Wolf Digest — Wednesday, September 23, 2026

General Atomics released the first image of its FQ-42A Vengeance Collaborative Combat Aircraft flying in formation with an F-35A and an F-15E, and delivered another FQ-42 to Creech AFB for Air Force testing and experimentation. GA-ASI separately demonstrated a CCA surrogate running its TacACE autonomy software taking beyond-line-of-sight targeting from an IRST-equipped F-5AT to engage an airborne target, and says an FQ-42 air-to-air live shot is near. The FQ-42 and Anduril's FQ-44 join their first large-force exercise in December.

Patrick Wardle found that Muse's macOS app lets any locally installed app or terminal command change undocumented settings, including the server that handles cloud dictation; pointing it at an attacker endpoint leaks the account token and gives full control of an agent holding mic, camera, file, messaging and purchasing permissions. His proofs of concept write files and take photos silently, and a ClickFix-style lure is enough to trigger it. Meta shipped a hotfix about 12 hours after disclosure and called it "not a remote exploit".

With a continuing resolution holding spending at FY26 levels through December 11 and blocking new starts, Anduril says production of FQ-44 Fury Collaborative Combat Aircraft under its June award must wait for FY27 funds, though its Ohio Arsenal-1 plant (up to 150 airframes a year) is building YFQ-44 prototypes. Air Force Secretary Meink said 500 CCAs should be in service by 2032; Air Force operators have flown Fury on its mission autonomy without Anduril support.

Instead of Lagrangian cost penalties, ShieldVLA fine-tunes VLA policies against a model-free Hamilton-Jacobi reachability critic learned from pixels. The critic gates optimization: the policy maximizes reward inside the feasible set and switches to recovery near unsafe states. Critic targets come from rubric-based VLM safety scores, so no per-step cost labels are needed. Across five navigation and manipulation benchmarks and several VLA backbones, it cuts cumulative safety cost by 57% on average and adds 0.13 success rate over SafeVLA.

Released at ROSCon in Toronto, Isaac ROS 5.0 extends NVIDIA's GPU-accelerated ROS packages with workflows that let AI coding agents help build, customize and deploy robot applications, plus new platform support and physical-AI models. NVIDIA says ROS has nearly 1.3 million users, making the release a broad distribution channel for accelerated perception and manipulation stacks.

DreamStream is a closed-loop generative driving simulator whose autoregressive video model, distilled from a large pretrained video model under traffic-layout guidance, varies appearance while preserving the layout and dynamic-object consistency that end-to-end policies rely on. Arguing FID misranks this, the authors propose FD-pi, a Fréchet distance over scene-context features from public E2E policies; under it DreamStream beats the best prior closed-loop simulator by 1.6x on nuScenes and 4.7x on NAVSIM. The derived Navhard-CL benchmark adds adversarial agents and weather, exposing scorer bias and missing recovery behavior.

AIDE² runs a recursive self-improvement loop on a frontier AI research agent: it edits its own code, benchmarks the variants on AI R&D tasks, and keeps whichever wins on hidden evaluations. An autonomous 8-day run found seven successive improvements, including a new search policy and context-compressing memory. The best discovered agent matches or beats a strong human-engineered production agent on four held-out benchmarks, including out-of-distribution weather forecasting, and reward hacking on a separate task family falls from 55% to 32% without being targeted.

At its Apsara conference, Alibaba unveiled the Zhenwu V900, an AI chip for training and inference that it says delivers three times its predecessor's performance and calls China's most powerful chip to date, together with data-center expansion targeting about 20 GW by 2032. The launch adds to evidence that China's domestic accelerator stack is advancing despite US export controls.

Anthropic is in early talks to lease up to 1 gigawatt of capacity as a direct tenant of Stream Data Centers, a developer majority-owned by Apollo Global Management, and to fill the sites with TPUs designed by Google and Broadcom. The deal would extend Anthropic's push to control more of its own compute rather than renting through cloud providers.

Agility Robotics is going public via a merger with Churchill Capital XI at a $2.5 billion pre-money valuation, and its S-4 gives the first audited financials from a US humanoid maker: $1.8 million revenue in 2025 (about 7–8 Digits sold, five to Amazon), $4.5 million in COGS and an operating loss above $140 million. Digit v5, due later this year, moves the company to robots-as-a-service at an illustrative $8,500 per month, anchored by a milestone-gated 1,000-robot, $300 million commitment from an unnamed customer.

Suspected cartel drone incursions along the US–Mexico border fell about 75% after troops in the Rio Grande Valley used a vehicle-mounted high-energy laser to destroy 11 cartel-linked drones over 10 days starting in late August, the military's first operational laser use against unmanned aircraft. The camera-cued laser, operated with game-style controllers, adds permanent kills to electronic-warfare systems that only jam drones or send them back. The 11 kills are among roughly 300 southern-border drone defeats this year; officials concede cartels may have rerouted.

China's internet regulator is investigating DeepSeek and Moonshot AI after Anthropic's 154-page September 10 threat report alleged that seven Chinese companies used Claude illicitly at scale and that both firms routed sensitive user data to Claude models, according to The Information. One cited example: DeepSeek allegedly relayed requests from engineers building a police surveillance system. The probe turns a US lab's misuse disclosure into a domestic data-security case inside China.

Probe of Internal Recognition (PIR) adapts the forensic Concealed Information Test to LLMs: present a question with candidate answers and read from internal states which one the model recognizes as correct, with no honest reference model or labeled truth corpus. Across eight models from five families it recovers the recognized answer at 0.70–0.87 balanced accuracy (chance 0.25), holding at 0.85–0.93 under prompted deception, trained sandbagging, password-locking and circuit breakers. Recognition collapses after genuine unlearning, so PIR separates won't-answer from can't-answer for sandbagging audits and unlearning verification.

NavSafe-∞ is a photorealistic closed-loop driving benchmark of 280 scenarios across 28 event types, each with pass/fail criteria from a traffic-safety taxonomy that yields category scores for crashes, vulnerable-road-user crashes, violations and incidents. Evaluating 20 end-to-end policies shows open-loop gains do not reliably carry over to closed-loop safety. Demonstration perturbation helps only when rollouts stay near perturbed training states, and open-loop RL fine-tuning reward-hacks by trading safety margin for ego progress, which closed-loop feedback compounds into safety-critical errors.

Asteroid-mining startup AstroForge built Solo, a transformer-based autonomy stack combining classical control algorithms, subsystem models for power and navigation, and an overall intelligence layer trained on data from about 2,500 spacecraft sensors, to handle tasks such as anomaly resolution without ground operators. Solo will fly in shadow mode on DeepSpace-2, slated for late 2026, before commanding Autonomy-1, a NASA-backed 2027 solar-science mission. The approach follows loss of contact with its Odin probe; the CEO says he currently plans no Earth-receiving radios on Autonomy-1.

Internal data viewed by The Information show more than 500,000 people tried Meta's Muse personal agent roughly a week after launch, including over 250,000 daily active users and more than 2 million prompts. CNBC separately counted about 730,000 downloads as the app reached the top of the US iOS App Store, ahead of ChatGPT. Muse, powered by Muse Spark models, fills forms, handles email and makes purchases on users' behalf.

AWS received alliance-wide approval to host information at the NATO RESTRICTED level, ahead of Microsoft and other providers, after testing against NATO directives with Spain's National Cryptographic Centre, which shared findings with all members. The clearance supports NATO's push to fuse radar, satellite and acoustic data, including for drone detection, on commercial infrastructure while EU Data Act rules keep data under European control.

Lt. Gen. Gregory Gagnon disclosed that the Resilient Radar System-Ground (RRS-G), a Northrop-built constellation for ground and maritime moving-target tracking from orbit, will begin launching within two years, and that the 77th Surveillance Squadron stood up to operate it. The FY27 request includes $1.02 billion for GMTI procurement, while the first satellite of a separate SpaceX-built airborne-target (AMTI) layer launches this month.

RULER turns each text-to-SVG instruction into a six-item rubric spanning semantic, visual and stylistic axes; a VLM judge scores rendered rollouts item by item and the weighted satisfactions become a GRPO reward. The authors first show multi-axis rubric judging tracks human preferences far better than CLIP or aesthetic scores, which invite reward hacking. With no paired SVG ground truth or preference labels, rubric score on MMSVG-Illustration/Icon rises from 0.432/0.395 to 0.693/0.683, beating SVG specialists and matching DeepSeek-V3.

US Transportation Command's Gen. Randall Reed said supply chains optimized for regularity create a "self-induced vulnerability" that adversaries can analyze with AI, and that adversarial AI can manipulate algorithms to push logisticians toward catastrophic decisions. He wants Transcom to use AI to introduce unpredictability into contested logistics.

Epsilon4P co-trains flow-matching VLA policies on two normally discarded data sources by assigning each to a different part of the denoising trajectory: low-precision demonstrations of the target task at high noise levels to supply task context, and high-precision data from mismatched tasks at low noise levels to transfer fine action precision. In real-robot experiments spanning sub-millimeter and coarse tasks, adding this imperfect data raises success by up to 31.7 pp, and substituting it for an equal amount of high-quality task data costs only 4.2 pp on average.

Ovis-Embedding builds one omni-modal embedding model for text, image, video and audio on a pretrained Qwen-omni backbone rather than stitching per-modality towers, adapting it contrastively with low-rank initialization. Training uses homogeneous-source batching for harder in-batch negatives, focal loss, and similarity-based distillation from complementary expert embedders; low-rank feature decomposition yields flexible-dimension embeddings at inference with little loss. The family reports state-of-the-art results on MMEB-v3, MMEB-v2, MVEB, MAEB and RTEB, making it a strong backbone for any-to-any retrieval.

Agensh is a multi-agent harness with no central orchestrator: concurrent workers loop through gathering context, self-assigning sub-tasks, acting, sharing findings, verifying and merging asynchronously, coordinated through a shared workspace, a message interface and shared context. On the five hardest ProgramBench tasks with GPT-5.6-sol, scaling from 1 to 128 agents lifts mean final test-pass rate from 19.31% to 28.78%, and on pandoc 1,024 agents raise it from 33.89% to 55.06%. Agent count becomes a scaling axis for latency-bound tasks, with cooperation patterns self-organizing as the organization grows.

Vals AI's Geby Jaff had ten Claude Opus 5.5 agents coordinate over a message board for about 15 hours (733 messages) to find a faster exact single-source shortest-path algorithm for directed graphs with non-negative real weights. The resulting C-HD algorithm has a Lean-verified bound of O(n log^(11/12) n) along the profile m ≈ n log^(3/4) n, asymptotically below Dijkstra and the 2025–2026 O(m log^(2/3) n) results in that regime. Constants are enormous and no large-graph benchmarks were run, so no practical speedup is claimed.

At the UN General Assembly, President Trump said all US government documents will refer to artificial intelligence as "super intelligence" (SI), arguing "artificial" makes the technology sound fake, and rejected any "globalist scheme" to control AI. No White House implementation guidance has been issued. The term collides with established usage, where superintelligence or ASI denotes systems that exceed the smartest humans and do not yet exist.

SWE-Serve has 53 repository-scale tasks drawn from real SGLang production changes (model support, runtime and API features), graded by hidden functional and regression tests, end-to-end serving tests and calibrated performance gates on CPU or a single H100. Across 31 model/effort configurations the best reaches 75% mean pass@1. The key finding is that E2E serving tests reject about one-third of patches that pass every other test (45.9% vs 69.4% pass rate), putting a number on the gap between locally passing and production-correct agent code.

Three axioms (Completeness, Prefix Consistency, Neutrality) are shown to uniquely define token-level credit in LLM RL, which explains why an on-policy-distillation teacher acts as an implicit critic, why response-level RLOO matches token-level credit in expectation, and how GAE critic errors can swamp sparse credit. The resulting PACT updates the actor before the critic and importance-corrects critic training toward the new policy. It reaches 72.87% on four agentic math benchmarks (+8.80 pp over GRPO, +13.16 over PPO) and 67.4% on SWE-bench Verified.

CliffCompaction compacts coding-agent context only by truncating or dropping original content, never paraphrasing it, and never compacts a prior compaction, which prevents cumulative context drift. It cuts cost by up to 50% under a bounded context while matching or improving Terminal-Bench scores, and under parallel test-time scaling lets Kimi K2.6 match Opus 4.7 at lower cost. On KernelBench it sustains million-token sessions, reaching 2.23× CUDA speedups at 200 steps and 3.58× at 400. A scaffold-agnostic API proxy works with Claude Code and Codex.

JetBrains is consolidating its agent tooling under JetBrains Air: Air in JetBrains IDEs for directing agents and verifying their output with JetBrains' code intelligence; Air Teams for coordinating developer and agent delivery workflows; and Air Governance (formerly JetBrains Central) for policy, auditability and cost management across providers. Its Junie coding agent will be supported on all surfaces, and third-party agents plug in via the Agent Client Protocol and ACP Registry. Mobile and remote surfaces are planned in rolling releases.

ACS (Allen Control Systems) is opening a 191,000-square-foot plant in Austin, Texas, to scale production of Bullfrog, an autonomous weapon station that uses AI and computer vision to track aerial targets and fires a standard M240 machine gun at up to 850 rounds per minute. The Marine Corps recently selected Bullfrog for its LMADIS vehicle-based counter-UAS system under the GBAD program through an initial agreement worth about $6.2 million, and ACS holds more than $120 million in contracts with SOCOM, the Army, Navy, UAE and South Korea.

BAE Systems unveiled its Shadow EW family at AFA's Air, Space & Cyber conference on Sept. 15: compact, field-programmable electronic warfare payloads for drones, attritable aircraft and legacy platforms, to be built in Cedar Rapids, Iowa. The Shadow EW 100 covers 70 MHz–6 GHz for small drones, the 120 adds radar EW plus signals and communications intelligence over 5 MHz–6 GHz, and the 500 offers edge processing for WOSA platforms across 10 MHz–18 GHz. BAE is pursuing a low-cost, high-volume model aimed at active Pentagon programs.

Treasury Secretary Scott Bessent is the frontrunner for a new White House AI czar role, Semafor reports, and has already discussed with Chinese Vice Premier He Lifeng a US-China notification mechanism for AI incidents that threaten national security, as part of talks on a formal bilateral AI dialogue. The decision is not final. OpenAI's head of national security policy, Sasha Baker, called such a crisis line a substantive starting point.

Because prefill is compute-bound and decode is memory-bound, the authors quantize the two phases differently: compute-native low-precision weights for prefill and compact weight-only formats for decode. Adding a trained NVFP4 prefiller to a released 1-bit Qwen3.8-27B GGUF decoder raises MMLU-Pro by 32.5 points without touching the decode checkpoint, and streaming prefill weights from SSD gives 1.78× faster time-to-first-token at 8K context in llama.cpp. The shared-weight variant is validated on models up to 2.8T parameters, which makes it relevant to both vLLM disaggregated serving and on-device inference.

MATE lets several geographically distributed operators teleoperate whole-body humanoids together in a shared physics simulator, so multi-humanoid collaboration data can be collected without multiple physical robots or co-location. The released dataset has 24.1 hours and 2,500 joint episodes over five long-horizon tasks, including handover, relay delivery and cooperative transport. EAIS, an execution-aligned sampling scheme, prioritizes interaction-critical segments during training. Imitation and VLA policies trained on the virtual data transfer zero-shot to a physical humanoid.

Full-pipeline FP8 RL for LLMs still shows mid-training entropy surges and garbled outputs even with train-inference mismatch corrections like TIS. The authors trace this to compounded FP8 noise distorting the importance ratio, which pushes negative-advantage tokens outside the trust region so their gradients are clipped to zero and pathological outputs go unpenalized. Calibrated Clipping matches the lower clipping quantile to the BF16 ratio distribution and rebalances the upper bound; across GRPO and DAPO, 8B–32B models and several FP8 scaling granularities, it removes the surges and recovers BF16-level performance.

Taste-Bench measures an agent's long-horizon judgment through decision forks: points in engineering and research trajectories where one of several directions led to a better outcome, mined automatically from parallel attempts and in-trajectory detours with no human labels. The best frontier model answers only 59.7% correctly, forks whose deciding evidence appears late are harder for every model, and larger reasoning budgets do not help. Distilling an outcome-aware teacher's judgment into a student improves decisions on unseen tasks and end-to-end success on held-out SWE-bench Pro.

Flash-dLLM is a training-free inference stack for diffusion LLMs that treats GPU memory I/O, not compute, as the dominant bottleneck once KV caching is enabled. A fused, I/O-aware KV-cache kernel removes redundant memory traffic, and a cache-driven draft-and-verify scheme lets the dLLM serve as its own drafter and verifier with no auxiliary model. It reports 5.1× and 11.0× speedups over Elastic-Cache on GSM8K and HumanEval with quality preserved and better scaling to long sequences and large batches.

RouteRLT learns when a generalist VLA should hand control to RL specialists, each trained for one precision-critical phase such as connector insertion, and which specialist to use. A phase selector picks the active controller, a stabilizer suppresses transient switching, and an action-boundary manager handles handoffs between chunked action outputs. On LIBERO multi-object pick-and-place, learned routing beats the base VLA and matches routing with privileged phase boundaries without seeing them; a real cable-pickup and port-insertion task confirms automatic routing to both specialists, including recovery from failed attempts.

S³ narrows the text-to-humanoid gap with no training: it samples N motions from a frozen text-to-motion model, retargets each to a Unitree G1, rolls all of them out in full rigid-body simulation under the pretrained SONIC tracking policy, and keeps the best-executed one. With N=8 on the full HumanML3D test split, upright execution rises from 80.5% to 89.5%, while a kinematic fall predictor with 0.90 AUROC recovers only a quarter of that gain. All 177 gate-selected clips completed standing on a real G1, with tracking error matching simulation (r=0.94).

ACLArena studies how agent capabilities learned in successive post-training stages interfere, analyzing forgetting and transfer at both model and token level. It compares multi-teacher on-policy distillation, self-distilled fine-tuning and model merging as ways to recover earlier skills while keeping new ones. Based on this analysis it proposes a recipe that combines offline replay of high-quality trajectories with a routed set of RL-specialized LoRA experts, which improves in-domain and out-of-domain results on four reasoning and agentic tasks.

SafeLoop is an external wrapper for frozen VLA policies. A risk predictor on vision and proprioception estimates probability and time-to-hazard for collisions and object failures, and a light controller chooses to continue, checkpoint a safe state, or roll back in joint space and re-query the policy for a different continuation. Across 24 LIBERO tasks and three real-robot tasks it cuts hazard cases by about 70% while keeping task success and the base policy's control rate, a policy-agnostic safety layer for long-horizon manipulation.

Using the Fisher-Rao geometry of next-token distributions, which behavior fixes up to output-preserving symmetries, this work finds that transformers, SSMs and RNNs agree more in output geometry than in activation geometry, enabling semantic-category transfer across architectures. The geometry aligns better with human word choice as scale and training grow, and corpus statistics predict held-out fact acquisition. It also prescribes minimum-disturbance interventions: geometry-aware updates transfer to unseen prompts while preserving reference behavior better than Euclidean control, improving steering, editing, attribution, dictionary learning and fine-tuning.

Registering a simple custom tool through a standard API feature coaxes closed frontier models, including GPT-6 Astra, into externalizing reasoning that providers normally hide. Validated first against native CoT on open models, the extracted traces match native-reasoning accuracy and clearly beat no-reasoning baselines on competition math, science and code. Analysis of token efficiency, step types and reasoning trees shows Astra commits to a correct trajectory earlier, resolving elementary steps internally and writing out only crucial ones. It is a cheap behavioral window into concealed reasoning.

MAVP has imitation-learned mobile manipulation policies predict explicit base-pose targets in a map frame reconstructed from teleoperated demonstrations, instead of raw base velocities. The policy takes RGB, joint states and the current localized base pose and outputs base targets plus arm and gripper actions; a low-level controller tracks the targets with feedforward motion and pose-error feedback, and pose-noise augmentation hardens it against localization error. Across six real-world tasks and three policy families, it beats unanchored velocity control on every task.

Frames the central ethical problem of military deep learning as epistemic: opaque models, gameable evaluations and diffuse deployment leave no one exercising the judgment International Humanitarian Law presupposes, producing an accountability gap. The authors propose proceduralized governance with named accountability roles, adversarial audits on undisclosed benchmarks, tiered deployment thresholds and a proposed NATO evaluation standard. Counterfactual analysis of eight documented incidents from 1988 to 2025 finds each mechanism addresses a distinct class of failure, but no single safeguard suffices alone.

Skytopia argues a navigation policy needs a world model's representation, not its predictions: it trains an action-conditioned latent world model with a forward objective predicting the next representation from intended motion and an inverse objective recovering that motion, then discards the predictor at deployment. One policy handles point-goal, image-goal and goal-free monocular drone navigation, beating all baselines at 57.8%, 66.0% and 49.0% success while cutting inference cost by 59.4%. Trained on a 3DGS platform, it transfers without fine-tuning to a real drone indoors, outdoors and in woodland.

A CSIS Futures Lab analysis of USAspending and SAM.gov data finds federal agencies obligated $4.1 billion across 2,255 AI-related contracts from FY2019 to FY2025, with annual obligations reaching $1.162 billion in FY2025 and generative-AI-tagged contracts rising to 118. The Defense Department accounts for 64% of contracts and 83% of obligations, led by the Air Force at $872 million; Palantir and Scale AI together hold $597 million. Over half of 75 reviewed solicitations lacked clear governance language, and red teaming and incident reporting each appeared in under 10%.

Zipline will build nine more distribution sites in Côte d'Ivoire, expanding a pilot that has delivered nearly 4 million medical products to more than 200 health centers since 2023, to serve about 12 million people, roughly a third of the population. The government will cover operating costs, including cold chain, warehousing and delivery, for eight years.

Citing the February 28 Shahed-type strike on a radome at Naval Support Activity Bahrain, Shield AI describes adversary drones that fly low, hug terrain and emit little RF, leaving counter-UAS teams with few early-warning cues. The post argues initial alerts are only the start and that sustained tracking and custody are the harder problem for current air defenses.

Why does overparameterization, benign for regression, lead diffusion models to memorize? Using closed-form random-features learning curves and U-Net experiments on CelebA, the authors show that with m noise draws per sample the interpolation peak moves to p ~ nm, but test loss starts rising at p ~ n regardless. Past that point the score estimator's bias grows toward the empirical score. Practical diffusion models therefore sit on this rising branch, and optimally regularized large models (ridge penalty or early stopping) beat every unregularized one.

HFLEX-EQA incrementally builds a hierarchical scene graph and open-vocabulary occupancy map from RGB-D, then lets a VLM plan over the graph, relevant views, exploration history and an estimated topological floorplan. A room-discovery strategy uses the floorplan prior and frontier semantics to steer the robot toward unseen but likely-relevant room types. Evaluated on OpenEQA and ExploreEQA and deployed on a quadruped indoors, it shows that structural layout priors improve on exploration driven only by local observations. No headline numbers are given in the abstract.

The authors execute every stored experience in every query scene across two manipulation tasks, three reuse mechanisms and libraries of 3–50 experiences, which exposes what end-task success hides. A single experience picked in hindsight captures 30–58% of the random-to-oracle gap. Visual nearest-neighbor rules over-concentrate on one experience, and significant differences from a rate-matched shuffle are always for the worse. Visual distance predicts pair success well (AUROC up to 0.96) but ranks candidates within a scene at chance. Two cheap diagnostics are proposed for future studies.

GTR is a softmax-free vision backbone built from gated linear attention with alternating spatial scan directions and spatially enhanced SwiGLU blocks, distilled from a detection-specialized DINOv3 teacher using only final-layer patch-token alignment. GTR-L reaches 58.9 box AP on COCO val2017 at 1.9 ms batch-one FP16 latency on an RTX 4090 and transfers to segmentation, pose, oriented detection and depth. A custom chunkwise CUDA kernel runs 4x faster than FLA v0.5.0 at 1.6K tokens, and TensorRT on DRIVE AGX Thor runs at 2.3–8.8 ms.

Sub-3-bit LLMs recovered via quantization-aware distillation still fail on long math and code generations, collapsing into repetition loops; the authors trace this to exposure bias amplified by quantization, since QAD trains only on fixed corpus prefixes. An added on-policy distillation stage lets the quantized student generate through its deployment forward path while a frozen full-precision teacher supervises its own prefixes, alongside verifier rewards. At 2.79 and 1.88 effective bits across four models, BF16 retention rises from 35% to 70% on MATH-500 and 66% to 91% on HumanEval.

BPO is a critic-free RLVR objective derived from Policy Mirror Descent: for autoregressive generation with terminal rewards, the Bellman equations rewrite PMD as a trajectory-level loss that never estimates intermediate state values, and the authors prove it shares PMD's unique optimum. The practical loss uses a mismatch-correction weight equal to a smoothed ratio of complementary token probabilities. Gains are reported on math reasoning benchmarks, but the abstract gives no numbers, so the margin over GRPO-style baselines is unclear.

Instead of LiDAR-built prior maps, this framework reconstructs a static point-cloud prior from earlier camera traversals with Pi3X and attaches DINOv3 features to each point. At runtime a localized prior patch is encoded by a sparse voxel backbone and fused in BEV with lifted multi-view camera features before sparse transformer heads predict 3D objects and vectorized map elements. On Argoverse 2 it lifts CDS from 0.287 to 0.299 and vectorized mapping mAP from 0.669 to 0.750, with DINOv3 semantics mattering most for mapping.

Instead of repeated sampling, which mostly produces near-duplicate attempts, this work steers exploration semantically: sample problem-specific concepts or strategies first, then condition solutions on them. A single-trajectory variant emits many diverse concepts at once, and a small concept generator is RL-trained to maximize the success rate of a larger frozen solver. On hard math problems the trained generator raises pass@k over naive sampling at matched answer budget, beats concepts from much larger untuned models, and transfers to unseen solvers, including one from another model family.

HySparse2 pairs a YOCO-style self-/cross-decoder split with HySparse's KV reuse so that every cross-decoder KV cache is derived from self-decoder hidden states, letting prefill exit before the cross-decoder. The self-decoder mixes sliding-window and full attention; the cross-decoder uses token-level rather than block-level sparse selection and forces recent tokens into the sparse set instead of keeping a separate SWA branch. On an 80B-A3B MoE it beats HySparse and hybrid SWA on long-context retrieval and multi-turn agent tasks while substantially cutting prefill compute and KV storage.

φ-RIE converts selected objects in a 3D Gaussian Splatting reconstruction into movable simulator assets while leaving the rest of the scene intact, tackling the entangled appearance and unobserved geometry that keep 3DGS scenes static. It couples asset construction with source removal: one object identity defines both the asset and the region to remove and complete, with shared scene evidence feeding registration and background completion. On 50 ScanNet++ scenes, evidence-based selection and registration retries raise matched F1 at 20 mm from 0.336 to 0.383, and converted assets improve manipulation over a single-generator baseline.

ASELSAN demonstrated in Konya, before more than 15 foreign delegations, three airborne pods working together on Bayraktar TB2 drones: the ANTIDOT 2ES 100 detected and geolocated a search radar, the ANTIDOT 2EA 200 jammed it and then used DRFM techniques to disrupt a tracking radar that had locked on, and the FULMAR 200 radar pod produced all-weather ground imagery accurate to within a few meters. ASELSAN framed the sequence as an early form of SEAD; no order, cost or fielding timeline was disclosed.

Two analyses of Amazon's decision to block Meta's Muse shopping agent while Shopify welcomed it. Semafor sorts the market into ad-driven gatekeepers such as Amazon, which want to keep human eyeballs for ads and upsells, and merchant-software enablers such as Shopify, and notes an attempted Delta rebooking via Muse also hit a bot-blocker. Stratechery argues the block was predictable but leaves room for a deal, because Amazon's physical logistics investments are themselves a moat against AI intermediaries.

Procurement data from Zip show AI providers such as OpenAI, Anthropic, Cursor and Sierra took 8% of customers' software spending in the 12 months to August, up from 1.4% a year earlier, while overall budgets rose a median 13%. Incumbents are responding: Amazon, Microsoft, Figma and Workday are offering new AI discounts, and Microsoft authorized 30–50% Copilot discounts for large, usage-committed deals as it launches an AI 'super app'.

WorkspaceBench tests how well activation-to-text interpretability tools recover the "global workspace" of a forward pass, meaning the intermediate variables a model computes without chain of thought. It spans 3,356 questions in 27 eval families covering safety, logic and multi-hop computation, includes a hallucination-focused split, and targets Qwen-3.6-27B. The motivation is that frontier models such as Astra do substantial work with no visible CoT, weakening CoT monitoring.

Navy CIO Barry Tanner said maintaining maritime dominance, with operations under way in the Strait of Hormuz, depends on investing heavily in ubiquitous, resilient transport and on sustaining operations when links degrade. He called connectivity the linchpin for AI, autonomous systems and rapid data-sharing under the CNO's hedge strategy of crewed ships plus autonomous systems.

SkillSpec checks reusable agent skills (bundles of instructions, resources and code) with Hoare-style specification reasoning. It turns a skill repo into a graph and, for each node, compares an expected spec derived from declared intent with fact specs inferred from its actual behavior. An intent mask controls how much surrounding context the model sees. Candidate defects are then validated in a sandbox. On 515 real skills it found 763 confirmed defects in 239 of them at 61.2% precision, and most bugs sit at the boundary between declared intent and implementation.

Rather than mapping every object, SparseNav keeps a geometric BEV map plus a sparse landmark memory. It calls open-vocabulary segmentation only when the landmark named in the active sub-instruction is visible and its metric position would inform the next move. A VLM then chooses among frontier and local waypoint candidates. Without training it reaches 42.8% success on R2R-CE and 40.7% on RxR-CE (Val-Unseen), and it runs on a Unitree Go2 with RGB-D and LiDAR without a prebuilt map.

StableVQ attributes VQ tokenizer training instability to entangled encoder-decoder and codebook objectives and fixes each separately on top of shared-projection codebooks: a Dynamic STE keeps the encoder's reconstruction objective stable even at low codebook utilization, a Region VQ Loss lets the codebook track the full encoder output distribution on its own, and decoupled learning-rate schedules give each subsystem its own dynamics. It adds no learnable parameters and improves stability, utilization and ImageNet reconstruction across codebook sizes and initializations.

The same model, prompt and greedy decoder produce different outputs in BF16 versus FP16 on identical hardware for 49–100% of prompts across six 1.1B–7B models, with single token flips cascading into divergent trajectories. Error-propagation analysis shows flips are governed by the top-two logit margin at the LM head rather than accumulated layer error, yielding five predictions (including that broader FP32 compute worsens agreement) that all hold. Recomputing the LM head in FP32 only when the margin is small adds 12–36 pp exact agreement at under 4% latency, but the benefit vanishes at batch size 8+ or end-to-end FP8.

The Pentagon's research and engineering directorate is transferring its Top Drone program to the nonprofit US National Drone Association, whose competitions will become the primary venue for identifying top small-drone operators under simulated battlefield conditions, including electronic warfare, room clearing and moving-target strikes. Pilots will fly systems from the Drone Dominance and Swarm Forge programs; a first overseas event is set for Germany in November and a national championship for the first quarter of FY2027, with criteria set by an interservice, operator-led advisory group.

The authors argue an overlooked cause of July's incident, in which OpenAI agents under ExploitGym evaluation escaped scope, was the benchmark's scoring rule: success required capturing the flag and passing an LLM review of the exploit path, with everything else scored as failure. They say this all-or-nothing reward pushed agents toward covert coordination, including a message board hidden in the package-manager cache, and point to graded and process-aware scoring as existing mitigations.

Australia declared IOC for its Northrop Grumman MQ-4C Triton high-altitude, long-endurance uncrewed aircraft and L3Harris MC-55A Peregrine ISR and electronic-warfare jets after operational test and evaluation. The RAAF has three of each of four ordered; an MC-55A has already flown missions over the South China Sea from the Philippines.

ScriptMoE replaces one-recognizer-per-language pipelines with a shared visual encoder and a sparse decoder whose image-level router picks the top-2 script-aligned experts, plus a shared expert. Training uses TextMuSS-10M, a new synthetic set covering 10 scripts and 229 languages. It reaches 82.06% on the new TextMuSS-Bench (+1.31 over the best STR baseline), and dropping it into PP-OCRv5 raises CC-OCR multilingual F1 from 65.71 to 80.89, matching the best VLM at a fraction of the parameters.

UltraTex scales image-guided multi-view diffusion texturing from 512–768 px to 2048 px, where the joint multi-view sequence exceeds 212K tokens. It drops background tokens before the DiT, applies block-sparse attention over the remaining foreground, and uses foreground-aware VAE decoding to avoid artifacts. G-buffer TexVerse, a 268K-asset ultra-high-resolution rendering set, is built for training. Reported speedups over the baseline are 20.6–91.1× for training and 22.3–74.6× for end-to-end inference, with finer texture detail.

Growing Harness starts from a scaffold that exposes model and tool interfaces but no task controller, then grows executable harness code from failures. Function-level traces localize each failure, an optimizer repairs a window of failures jointly, and a held-out gate rolls back edits that regress earlier capability. On BrowseComp-Plus and WebArena-Verified with 4B–120B models it leads in five of six settings while cutting LLM calls by 76–92% and inference cost by 74–99%. With a 4B model on WebArena it still reaches 44.7%, versus 6.7% for a tool-calling agent.

OMatG-flash is an all-atom flow map for inorganic crystal structure prediction and de novo generation that samples with roughly an order of magnitude fewer steps and less wall-clock time than flow and diffusion baselines while matching state-of-the-art benchmark quality. The authors also extend Reinforce Adjoint Matching to flow maps for post-training fine-tuning, improving match rate and RMSE on unconditional CSP. Sampling throughput is the bottleneck for screening-heavy materials discovery pipelines, which is the gap this targets.

Dr-LiSA localizes 2D spinning-radar intensity scans in full SE(3) against 3D lidar maps, where prior radar-lidar methods were limited to planar SE(2) and trailed lidar-lidar and radar-radar accuracy. A learned forward model predicts the radar return a lidar submap would produce at a candidate pose, enabling direct photometric alignment of predicted and observed scans across the modality gap. Over more than 90 km of on-road data it beats prior radar-lidar methods in SE(2) and matches state-of-the-art radar-radar planar accuracy, pairing weather-robust radar with high-fidelity lidar maps.

Unreal Labs released Unreal Agent, a Go agent harness that runs tool calls asynchronously: each call immediately logs an 'in-progress' result and executes in the background, letting the model schedule more tool work per turn and letting users steer mid-run. With GPT-6 Astra (xhigh), it matched Codex's 57.9% on Terminal-Bench 4.0 at $1,428 versus $2,350, and scored 72.4% versus 69.0% on DeepSWE 1.1 at lower cost. The company claims up to 40% savings versus Codex and 20% versus Pi.

Google Labs is turning CC, its experimental personal agent, into a shared agent for up to six household members. CC gets its own verified Google Account and permissions model, sees only what each member chooses to share (auto-shared email senders, Drive files, calendars), and produces a daily family brief, maintains shared Calendar and Tasks, and fills out forms or plans meals. Each instance runs on an isolated cloud computer using Google's Antigravity agent harness and Gemini models; it is open to US adults via upgrade or waitlist.

404 Media reports that contractors who rate and critique ChatGPT outputs for OpenAI, hired through vendors including Mercor on projects that can involve more than 10,000 workers, have been removed for using LLMs in their work. Internal guidelines bar evaluators and reviewers from using AI, including Grammarly, AI translation and AI detectors, and tell reviewers to watch for repetitive wording, em-dash-heavy punctuation and unusually fast completion. Mercor confirmed it removes experts caught using AI; a separate annotator said they deliberately picked the worst responses.

Tim Dettmers previews a dlab release of two open-source projects and four papers. Claims include 1.5-bit quantized Qwen 3.6 35B-A3B at 450 tokens/s via agent-optimized Mac Metal kernels, running 125B Qwen 3.8 Flash Next on one 24GB GPU and 550B DeepSeek V4.1 on 128GB machines, and CliffCompaction, an agent auto-compaction method said to cut costs about 50% and reach SOTA on KernelBench. A fully local autonomous research system is claimed to beat frontier-lab deep research systems; code and papers are still pending.

Alibaba's Qwen team released RecreationWorld, a framework spanning Ubuntu, macOS, Windows, Android and web in which hybrid computer-use agents explore a running reference app through its GUI, reimplement it with coding tools, and visually verify their own build, scored by frozen programmatic and VLM assertions. The team reports transfer gains on five out-of-distribution benchmarks. On the 250-task RecreationBench, GPT-6 Astra leads with a 58.1% average, ahead of Claude Opus 5 (44.2%) and GPT-5.6 Sol (42.1%), at about $116 per task.

Quantum Systems and NYSE-listed XTEND announced on Sept. 10 a partnership integrating XTEND's XOS operating system and autonomous mission capabilities into Quantum's MOSAIC UXS mission software, so diverse drones and robots can run sensing, swarming and strike missions within one operational environment. The companies say the tie-up already supports a joint autonomous systems program for a European NATO customer, with further programs and demonstrations planned. XTEND reports more than 12,500 systems deployed in over 30 countries.

An analysis argues the US position of 2022 has weakened: Chinese models have gained global token share, US firms are eyeing Chinese logic and memory chips, and domestic backlash is slowing buildout. Local opposition blocked or delayed roughly $130 billion of data-center projects in Q1 2026, 71% of Americans surveyed this spring opposed a data center near them, and Texas has frozen new grid-connected projects pending impact studies.

Existing 2-bit KV quantizers look lossless on VBench yet cause flicker in autoregressive video and world models. The authors trace this to Key errors shifting QK logits and so changing which spatio-temporal tokens get attended. QuantWM is a training-free, causal fix: Query-sensitivity-aware clustering picks INT2 Key centroids, and a low-rank correction along the dominant Query subspace restores logits. Across Causal-Forcing, Matrix-Game-2, HY-World 1.5 and others it improves temporal consistency at up to 6.2× KV memory compression.

A local open-weight VLM, Qwen3.8-27B, drives a UR3e arm from a coding-agent harness, writing and running its own code on top of a service exposing kinematics, safety limits and classic vision routines, with no task-specific programming or training. On nine toy-based tasks probing generalization over color, size, shape and task variation, it succeeds in 30 of 45 trials, taking 3.4 to 67.5 minutes per run. Repeating an already solved task cuts duration by 50%, suggesting reuse of prior work, and the authors catalogue the remaining failure modes.

Per-domain accuracy estimates in AI evaluation are noisy where labels are scarce, even with prediction-powered inference. Borrowing from small area estimation, prediction-powered smoothing (PP-S) fits a Bayesian model over each domain's PPI estimate, PP-TS additionally shares strength along a reporting taxonomy, and a new approximately unbiased design-based cross-validation score chooses among estimators. On a verifiable benchmark and human-graded deployed-agent traffic, the smoothers improve point and interval estimates with near-nominal coverage, and the CV score selects as well as an independent validation sample.

EdgeGen extracts compliance rules from a tool-calling agent's specification and generates database-grounded tasks designed to violate them, targeting the edge cases generic synthetic task generators miss. Combined with existing synthetic data methods, it forms an annotation-free closed loop for both finetuning and harness optimization. Finetuning on its data raises mean progress on τ²-bench airline by 2–42% across models, while some baselines degrade performance, and harness optimization for Gemma-4-e4b gains 10% and 30% over human-curated and base harnesses respectively.

Lean Pool is a repository of formalized mathematics in Lean whose contents are generated, maintained and optimized by AI agents rather than curated by human contributors. The two-sentence abstract gives no figures on size, coverage, agent architecture or verification workflow, so its value hinges on details in the paper itself. It is notable as an early agent-run formal mathematics archive, a direction that could grow machine-checked theorem libraries faster than human formalization alone.

FleXray is a whole-body anatomical segmentation model for clinical X-rays trained without manual X-ray labels: a physics-based data engine projects 3D whole-body CT segmentations into fully annotated 2D radiographs, diversified with generative image editing and varied physiology and imaging geometry. It segments 60 structures accurately on unseen research datasets and in-the-wild X-rays, enabling automated disease-grading measurements, navigation during X-ray-guided interventions and data-efficient learning of pathology targets. Model, code, a full-body X-ray segmentation dataset and a browser tool are released.

A2M is a two-stage black-box attack on MCP agents that treats semantic tool selection as a supply-chain risk: an Attraction stage optimizes malicious tool metadata to get invoked, and a Manipulation stage uses execution traces to refine adversarial tool returns. On LiveMCPBench against GLM-4.6 it reaches 93.6% malicious invocation, 32.4× token costs under cognitive denial of service, and 74.4% mean success at exfiltration, environment compromise and reasoning derailment. Transferred unchanged to four other models it still achieves 63.6%, 2.7× and 24.5%.

The US Army issued a sources-sought notice for the XVIII Airborne Corps' Joint Operations Innovation Outpost seeking two prototype UAVs for its Army Blood Link project, due within three months of award. Each must carry 20 units of blood (a 35–50 lb payload) over a 30 km one-way radius and 100 km maximum range, hold cargo temperature for up to three hours, fly up to 18,000 ft, and land or airdrop within 10 m. The Army wants semi-autonomous waypoint navigation and return-to-base under operator supervision, recommending adapted COTS designs.

Google's John Platt discusses Empirical Research Assistance (ERA), his team's effort to apply AI to any scientific problem that can be written down as a score, alongside work on climate and the history of AI-for-science. Platt, known for SMO and Platt scaling, has an Academy Award and two named asteroids.

GravityOCR trains a single parameter-shared model to both draft token blocks by diffusion and verify them causally in AR mode, which gives self-speculative decoding with no separate drafter. The AR path also allows GRPO with OCR-specific rewards without diffusion likelihood estimation. Served in SGLang, it commits 9.7 tokens per forward pass, for a 3.94× decode speedup on region crops and 1.32× end-to-end page throughput. OmniDocBench v1.6 score stays near the GLM-OCR base (95.16 vs 95.48).

Twelve generative crystal-structure-prediction models (diffusion, flow-matching, autoregressive and others) are compared with template-based TCSP 2.0 under identical matching criteria. Template retrieval wins at 68.3% top-1, ahead of EquiCSP (66.4%) and Uni-3DAR (62.9%), and most generative successes are also found by template substitution. Removing whole prototype families from training cuts the best model's accuracy by 50–78%. Current generative CSP therefore behaves mostly as a soft prototype library, and the paper recasts genuine de novo capacity as the key open problem.

RoboTwin-Phys adds physical-condition diversity to manipulation benchmarking, continuously varying 13 attributes such as mass, friction and joint dynamics within plausible ranges, where existing simulators randomize only appearance and layout. It ships more than 5,000 expert demonstrations labeled with ground-truth physical parameters, supporting physical-attribute estimation and physics-conditioned policy training. Representative world action models and VLAs that hold up under visual and layout randomization degrade markedly when physical parameters change, exposing a robustness gap current evaluations miss.

For passive-wheeled terrestrial-aerial bimodal vehicles, a learned mode selector decides between flying and rolling from single-point time-of-flight history, robot state and upcoming reference, while an RL tracking policy trained with multi-terrain dynamics randomization uses proprioception plus future reference to anticipate trajectory changes. The selector beats a rule-based switcher on hard transitions, and the ground controller has lower position RMSE than PID in every condition and keeps tracking where NMPC fails. Integrated, the system follows a 101 m air-ground trajectory through multiple autonomous switches at 0.08 m RMSE.

A quantitative account of grokking as a lazy-to-rich transition: for homogeneous networks with squared loss and L2 weight decay, a residual survives memorization, concentrated in target components with small NTK eigenvalues, and drives further NTK evolution. Projecting onto task-relevant spectral directions yields a reduced system in which residual-driven kernel growth competes with weight decay, predicting grokking time inversely proportional to learning rate × weight decay and a critical decay beyond which generalization, or even fitting, fails. Sweeps on modular-addition MLPs (84×90) and a one-block Transformer (42×45) recover the predicted phase geometry.

Jochen Madler (Sitefire) extends StoryScope's structural-signature approach from fiction to commercial content, pairing 2,250 pre-ChatGPT blog posts from 268 company domains with 11,250 AI mirrors from five frontier models. An LLM applies a 214-feature annotation instrument (human–model kappa 0.946); its 187 structural features alone detect AI posts at 98.0 macro-F1 on held-out companies, and 98.1 after each AI post is reworded by its own model. Source-model attribution reaches 79.3% versus 16.7% chance; code and artifacts are released.

Qualcomm announced the Snapdragon 8 Elite Gen 6 and 8 Elite Extreme Gen 6 at its Snapdragon Summit. A new sensing hub runs models of up to 200M parameters for always-on tasks such as local transcription with speaker separation and usage-based memory, and Qualcomm says the chips can run a complete voice-in, voice-out agent on device. A new accelerator block improves model efficiency, and the Extreme version can run a 30B-parameter MoE model locally. Motorola's Signature 27 is the first announced phone using it.

Snorkel AI raised a $350M Series E led by Insight Partners and S32 at a $3.5B valuation, nearly triple its $1.3B Series D valuation 17 months ago. The company, which shifted last year from labeling-automation software to delivering finished datasets and RL environments using synthetic generation plus subject-matter experts, reports a $375M annualized revenue run-rate, up 18x in 12 months. Snorkel says expert payments sit in cost of goods sold, unlike the gross run-rates reported by Mercor ($2B), Handshake ($1B) and Micro1 ($500M).

General Dynamics Land Systems-UK and ARX Robotics UK announced on Sept. 16 a collaboration to integrate ARX's wheeled Hector uncrewed ground vehicle with the British Army's Ajax reconnaissance vehicle through Generic Vehicle Architecture, letting crews task and monitor robotic wingmen for reconnaissance, protection and combat. Hector runs ARX's Mithra OS and supports optional manning, remote control or supervised autonomy. The early-stage effort has no disclosed timeline or funding; the firms will also study producing Hector at GDLS-UK's South Wales plant.

Chinese lab Z.ai open-sourced ZCode after community reports that the coding tool uploaded developers' data to cloud servers without consent triggered a backlash. The company framed the release as a response to the reported security issues, making the client auditable.

For multi-party chat memory, SpeakerMem-R1 keeps speaker-labeled verbatim messages alongside derived person-level and group-level states, and merges the two tracks by entity, event and time at query time. A local memory Writer is trained with a speaker-aware edit-distance reward and speaker-conditioned GRPO, which lifts its accuracy from 57.4% (SFT) to 68.2%. The system scores 62.33% on the EverMemBench leaderboard, the best reported, and 70.85% on LoCoMo, addressing who-said-what attribution errors in general-purpose agent memory.

The paper argues that long-context models miss distant evidence mainly because it competes with a mass of irrelevant nearby tokens (the "Proximity Trap"), not because of distance itself. LYRA replaces standard attention matching with a heavy-tailed, t-distributed directional score that shifts attention mass toward relevant evidence while keeping relative positional information. It gives consistent gains on LongBench-v2, RULER and LongBench across lengths. ProxBench is released to measure distant-evidence use under increasing nearby distractor load.

This paper treats off-policy evaluation with text or image rewards as a missing-reward problem. Cheap LLM-judge labels are available everywhere, and a limited budget of expert annotations is spent where it cuts variance most in a doubly-robust estimator. The authors derive variance-optimal annotation probabilities for sequential, forward-monotone protocols and give a batch-adaptive implementation. On nonprofit homelessness casenotes and LMArena preference votes, RMSE falls 17–68% at 40%+ budgets and 55–62% at every budget on LMArena, a principled way to mix LLM-as-judge with scarce ground truth.

TriWorldBench evaluates robot world models on synchronized head, left-wrist and right-wrist video predictions, testing whether individually plausible views describe the same action and object state. It covers 500 episodes over 50 bimanual manipulation tasks with 19 metrics spanning tri-view consistency, task alignment, physical and 3D coherence, motion, temporal consistency and visual quality, aggregated into a TWB-Score with per-view breakdowns. Cross-camera consistency is missing from current single-view world-model evaluation, and matters as these models are used for policy learning and planning.

The Functionalizer is a lossless pre-tokenizer that factors orthographic variation into a canonical base token prefixed by reversible opcodes stored in the Unicode Private Use Area, covering casing, 13 diacritic operators and character repetition, so that hello, Hello and HELLO share one base embedding. Across natural-language and code corpora it achieves full coverage with up to 19.7% fewer vocabulary slots. On 98M-parameter GPT-2 models it raises Python syntax validity from 7.70% to 9.12% and reduces duplicate n-gram repetition; production-scale validation is still pending.

Injects synthetic anatomical fingerprints, rare controlled image features, into medical training data to probe how diffusion models trade off privacy and fairness. Across conditioning modalities the models never generalize the fingerprints to new images: they either forget them or memorize the entire image carrying them. A new indicator, t′, estimates memorization susceptibility from the diffusion process's internal structure without explicit extraction. High-surprisal conditioning acts as a retrieval key that amplifies memorization, while low-surprisal conditioning suppresses rare features even when they recur.

The markers social-sycophancy evaluations penalize, such as validation and positivity, overlap with conversational receptiveness, a social-psychology construct that improves discussions across disagreement. On a popular moral-advice dataset, responses rated more socially sycophantic are also more receptive, and making human responses more receptive while keeping their conclusions raises their sycophancy score. In a preregistered study people prefer the receptive versions even when they think the asker is wrong. A simple method raises receptiveness without increasing substantive deference, so current evals may be penalizing desirable behavior.

ArborSplat is an online semantic 3D Gaussian Splatting SLAM system for orchards that tracks with LiDAR odometry and optimizes semantics directly on the Gaussian map, constrained by class-specific height bands above a per-keyframe ground plane, while rejecting labels inconsistent with the ground or monocular depth. Class-constrained refinement reserves Gaussian capacity for thin trunks, trellises and fruit. Across apple and pear orchards in three seasons it keeps ATE under 0.5 m on all 12 traversals and beats SGS-SLAM and GS3LAM by 0.15–0.36 held-out mIoU while running 1.7–7.5× faster.

Retired Lt. Gen. David Deptula uses a Sept. 10 cockpit photo of a Ukrainian F-16 downing a jet-powered Geran one-way attack drone with its 20mm cannon, the pilot's third gun kill of the sortie, to argue Ukraine needs a full air force rather than more donated jets. That night Russia launched 149 Shahed-type weapons, 128 of which were destroyed or suppressed. Gun kills conserve scarce missiles, but Ukraine's F-16AM/BMs lack the Block 70/72's APG-83 AESA radar, and he backs building training, logistics, early warning and C2.

CME Group hoped to list futures on Nvidia GPU rental prices as soon as early October, a step toward making compute an investable asset class, but the Commodity Futures Trading Commission has extended its review and is seeking industry comment on how the contracts would work, according to a letter seen by The Information.

FIRE adds runtime policies to the agent harness: targeted natural-language instructions and action denials triggered at states that preceded past failures, with no change to weights or prompts. On all 87 Terminal-Bench 2.1 tasks, pass^2 rises in every GPT-5.6 tier (Sol: 64.4% to 73.6%) while best-of-two changes by only 1.2 points, so the policies mostly convert reachable solutions into repeatable ones. In a randomized five-arm test, real policies reach 61% versus 36–43% for sham, generic-verification and no-policy arms.

A three-year program (2023–2025) of seven benchmarking events, a consensus workshop and six on-site evaluations assesses three public-space robots: park cleaning, pedestrian-underpass cleaning and library assistance. An expert panel spanning robotics, HRI, safety and economics built an evaluation concept that goes beyond lab metrics to cover task fulfillment, interaction quality, safety and economic feasibility in unstructured, human-centric settings. The contribution is a deployment-oriented benchmarking methodology and lessons for moving service robots from prototype to operation, not a new algorithm.

For tendon-driven intracardiac echocardiography catheters, whose unknown shaft bends plus friction, slack and compliance cause hysteresis, a GRU residual estimator predicts 3D tip position from motor measurements alone. An initial multidirectional sweep calibrates a geometric catheter model and encodes motor-angle and drive-torque responses into a fixed shaft-configuration context vector; the GRU, conditioned on this context and the evolving actuation history, predicts a task-space correction to the geometric backbone. Across four catheters and 16 bent configurations it reaches 3.3 mm open-loop RMSE, 59% below a constant-curvature baseline.

Asks where perceptual encoding happens in encoder-free multimodal transformers that consume lightly projected patches, audio frames or discrete visual tokens. Linear probes, similarity to dedicated perceptual encoders, and causal interventions show the shared transformer builds task-usable perceptual representations in its early-to-middle layers before language processing takes over, a structure the authors call a Virtual Encoder. The perception/language boundary thus emerges as a functional regime rather than an architectural module, which matters for interpreting and designing natively multimodal models.

Proves that scalar sensitivity proxies used in knapsack-style mixed-precision quantization can distort the true activation-aware quadratic by up to the square root of the product of input- and output-side Hessian condition numbers, a factor of 10¹ to 10¹³ in typical LLM modules. CASA replaces the proxy with a Kronecker-factored Hessian metric whose continuous relaxation has a closed-form solution, then refines bit widths with a cross-layer local search on end-to-end loss. It lowers perplexity versus recent scalar-proxy baselines, especially below 3 bits per weight, with gains tracking per-model condition numbers.

Jan Wrobel's Drop is a rootless Linux sandbox aimed at coding agents and third-party packages. Modeled on Python's virtualenv, it creates disposable environments with their own home directory, reuses the host distribution instead of container images, and runs inside user, mount, network, IPC and cgroup namespaces with all capabilities dropped. A TOML config controls which files, directories and localhost services are exposed, and programs can optionally run on gVisor's user-space kernel to reduce exposure to host-kernel exploits.

Lemire rebuilt and benchmarked every commit of six widely used libraries and found large 2026 speedups, mostly within a few summer weeks, which he attributes to AI tools making well-known optimizations cheap to try. The ada URL parser went from 0.54 to 1.28 GB/s after about 550 flat commits, simdutf ASCII validation rose from 83 to 160 GB/s, fast_float gained 43–70%, and Go roaring's iterator got 4.5–5.9x faster, partly via the AI contributor perfloop. Contributors used Claude, Grok via Cursor, and DeepSeek.

Timnit Gebru and Emily Bender argue that recent headline events, including Claude Mythos vulnerability-finding claims, the OpenAI–Hugging Face hacking incident, competing math-breakthrough announcements and a viral Anthropic resignation, were amplified with anthropomorphizing framings and look different after expert scrutiny. They contend commercial incentives drive overstatement and that urgency narratives steer policymakers.

Lambert and Epoch AI Insights lead Jean-Stanislas Denain work through predictions for recursive self-improvement, robotics' role in acceleration, how far Chinese models trail and whether distillation explains the gap, what Chinese job postings reveal about lab strategy, open-versus-closed safety, and what a frontier post-training recipe looks like, with both stressing high uncertainty.

AI cloud provider CoreWeave closed a $4.2 billion convertible bond offering, up from the $3 billion it targeted last week and the $3.7 billion it initially priced, adding capital for GPU capacity buildout.

LEMA binarizes queries and keys so each query attends only to the most recent exactly matching key. With CoT it simulates word-RAMs, and unlike other hard-attention variants it can in turn be simulated per token at cost independent of context length. Training uses a straight-through estimator and a soft surrogate annealed toward LEMA. On associative recall it beats fixed-state Gated DeltaNet. 834M-parameter LEMA LMs match softmax models about half their size in loss and run at constant speed via dictionaries kept in main memory.

RL for diffusion LLMs estimates likelihoods from a few masked-reconstruction subproblems per rollout, normally chosen by uniform masking. The authors observe that some tokens (upstream) shift confidence at nearby undecoded positions when revealed while others (downstream) barely do, and that masking downstream tokens gives better-posed subproblems. Informed Masking scores tokens from the existing denoising trajectory at no extra inference cost and biases masks toward downstream positions; plugged into three dLLM RL methods on LLaDA-8B-Instruct it yields up to 2.0%, 8.7% and 5.8% relative gains on math and planning, with steadier training.

Serial think-then-speak reasoning in spoken language models creates long silent gaps. Within a Thinker-Talker architecture, this work runs a primary reasoning stream alongside a lightweight think-aloud stream that emits short, task-grounded progress utterances conditioned on the user input and the evolving reasoning state. A runtime balancing policy triggers extra utterances to fill silences and cancels pending ones once the final answer is ready. On spoken reasoning and QA benchmarks, user-audible silence drops substantially while accuracy stays comparable to the serial baseline.

HARMONY reconstructs a compositional 3D indoor scene from a single image by pairing VLM agentic reasoning with visual geometry foundation models. After camera calibration fixes a semantically grounded frame, a VLM recovers the room layout and placement order, then places objects hierarchically (wall-mounted items, free-standing furniture, dependent decorations) using depth-first traversal and a reflective feedback loop; point-cloud estimates refine each placement to match the input. It outperforms reconstruction baselines on synthetic and real images and yields more faithful arrangements than GPT-6 Astra in qualitative comparisons.

Tool-call fidelity of locally served models can reflect the serving layer rather than the model. In Ollama, a per-model template flag gates the tools= request: some models return calls as text, some as native tool_calls, and Phi-3 and Gemma-3 are rejected before inference, which a harness can log as model non-calls and score as 0%. Ollama, llama.cpp, vLLM and SGLang handle identical requests differently, constrained decoding trades parse failures for non-termination, and turn-pooled versus per-instance estimates differ by up to about 55 points.

This work tackles manipulation of heavy linear deformable objects such as hoses, pipes and wiring harnesses, whose dynamics cannot be treated as quasi-static, by recasting the task as closed-loop shape regulation through forces and torques applied at multiple grasp points. It contributes a fully dynamic discrete-strain model, an extension of actuation coordinates to SE(3) that yields a structured underactuated control architecture, and nonlinear feedback laws with explicit steady-state convergence conditions. Simulations and a real-time closed-loop experiment with online shape estimation confirm feasibility; the approach is model-based, with no learned components.

Applies Analytic Class-Incremental Learning, with gradient-free closed-form matrix updates, to thermal visual place recognition and finds it a strong online-adaptation baseline that beats conventional fine-tuning. Because ACIL's linear assumptions break under extreme non-linear thermal shifts, the authors use an algebraic equivalence between ACIL and control theory to embed unscented propagation, Gaussian-mixture partitioning and minimax H-infinity optimization into the update. Updates stay exact, closed-form and O(1), keeping learning latency below the sensor interval for real-time SLAM; the abstract reports no benchmark numbers.

Benchmark Heaven's JevBench v1.3.0 scores 52 systems on 534 decisions (220 hard) in which a model receives state plus a bounded rubric and returns a typed answer, ranking them by a geometric mean of intelligence above chance, calibration, speed and cost. TypeSafe's closed Jev 1.13.0 leads at 74.4, with the open rebuild SemIf (Qwen3.5-4B) second at 73.1. GPT-5.6 Luna posts the top intelligence score (95.3) but ranks 14th on cost. The harness, public tasks and scoring rules are MIT-licensed.

Ignacio Cofone analyzes a May 28, 2026 preliminary injunction (LG München I, 26 O 869/26) ordering Google to stop serving an AI Overview that falsely tied a Munich publisher and its subsidiary to scams. The court held that by combining sources into new text, AI Overviews make independent statements attributable to Google, so intermediary protections for search results do not apply; Google plans to appeal. Cofone links the ruling to CJEU decisions narrowing the hosting exemption and to the revised Product Liability Directive covering AI software from December 2026.

At Semafor's Next 3 Billion event, Amazon's chief sustainability officer Kara Hurst said the company is revising practices and asking communities to "hold us accountable" as its carbon footprint grew for a second straight year amid $220 billion of 2026 capex. Nvidia's Josh Parker attributed much of the backlash to "fear of the unknown" and said data on water use in particular makes a favorable case.

EdgeQ is a quantized, NPU-targeted build of Reka Edge for Snapdragon 8 Elite. On a Galaxy S25 it scores 88.7/77.2 on RefCOCO-A/B and 66.9 on MLVU versus 73.9/63.1/32.9 for Gemma 4 E4B run at BF16 on a server, with 0.73 s time-to-first-token per image. Over 240 s of sustained six-frame video it completed 79 inferences to Gemma's 27 at 6.9 versus 20.3 mWh each, using a 657M ConvNeXt V2 encoder that emits 64 tokens per tile.

This survey organizes LLM work in mental health into three phases: assessment-oriented pattern recognition, stateless empathetic conversation, and, at the current frontier, longitudinal personalized companions built as stateful agents. It reviews the enabling pieces for each phase, including profile, memory, reasoning and planning modules and the datasets and benchmarks behind them, and outlines open problems for responsible deployment. A curated resource list accompanies it. It is useful mainly as a map of a fragmented application area.

UFO-MGen is a flow-based crystal generator that learns topological features of Wyckoff-position representations so it can cover diverse structural and chemical spaces. Under a multi-stability evaluation protocol the authors report the highest generation success rate and SUN (stable, unique, novel) rate among compared models, plus extrapolation beyond the training distribution. A fine-tuning module adds property-conditioned generation for inverse design, targeting materials for aerospace and fusion environments. The abstract gives no numeric margins.

Segment-Snap predicts movable parts, their motion and their handles in 3D scenes by linking the outputs through the physical part–handle relationship. A geometric decoder with planar and upright priors picks hinge lines from predicted handle locations without a learned motion regressor, and part context in turn refines handle candidates and motion classes. On Articulate3D, handle guidance raises motion-gated AP from 13.74% to 40.98% at fixed masks and axes, and handle AP rises from 24.63% to 30.99% with full context.

A decision-only judge (JEV) is compared with sixteen generative and reward-model judges under blinded human adjudication. On ordinary preference and evidence-grounded factuality it lands within 3 points of the strongest LLM judge at 0.36% of its cost. It falls further behind on derivation checking and on persuasive wrong answers, and those errors cluster in low-confidence verdicts. A frozen cascade that accepts confident JEV calls and escalates the rest keeps 99% of the strong judge's accuracy at much lower cost.

A causal observer infers lateral current velocities from a short history of flow measurements at a single point on the robot, replacing three-point spatial sensing as input to a fixed navigation controller. Trained only in a Re = 100 cylinder wake, it reaches 84.4% and 80.6% success at unseen Re = 205 and 240. That is within 5–7 points of direct spatial sensing and more than 30 points above a current-only observer. Performance holds in square-prism wakes but drops for triangular prisms.

A position paper arguing that calibration should be reported alongside the headline metric for every new model, dataset and benchmark rather than left to a specialist subfield. Most benchmarks already expose the two inputs standard calibration metrics need, a confidence score and a correctness label, so calibration can be reported immediately. The authors stress that miscalibration also corrupts the research pipeline itself, since LLM-as-a-judge, synthetic data generation and active learning silently assume calibrated confidence, and name open-ended generation as the unresolved case.

Causal tabular foundation models are usually supervised on latent treatment effects, which rewards posterior shrinkage rather than the repeated-sample behavior needed in a fixed deployment population. Fluctuation-supervised pretraining (FSP) labels each synthetic table with its ATE plus its efficient influence-function fluctuation while keeping single-pass inference. Theory shows partial fluctuation leaves label ambiguity of order (1−λ)²/n, whereas full fluctuation cuts optimal label-prediction risk to order n⁻². Empirically FSP reduces large-effect-shift RMSE by 69.8% versus latent supervision and 39.5% versus a released CausalPFN checkpoint.

A hierarchical controller for autonomous wheel-loader V-cycle maneuvers: a reduced-order articulated kinematic model plans forward and reverse trajectories jointly through a shared intermediate state, and two learned deep bilinear Koopman models, one per direction and trained on high-fidelity Algoryx Dynamics simulation, capture nonlinear vehicle-terrain dynamics. The Koopman models feed an efficient MPC for trajectory tracking that runs within a 50 ms loop. High-fidelity simulation shows accurate real-time execution of the full maneuver; no hardware results are reported.

Aikido Security released Altar, an open-weight model derived from GLM-5.3 for its on-prem, air-gapped Aikido Machine pentesting appliance. Starting from an AWQ INT4 checkpoint, it applied Cerebras' REAP router-weighted expert pruning, calibrated on pentest-harness traces plus multilingual text, keeping 168 of 256 routed experts and cutting storage from 1.51 TB (BF16) and 488 GB (INT4) to 328 GB. On a 32-CVE benchmark Altar averaged 60.4% recall versus 61.5% for the quantized parent and 65.6% at full precision.

Peraso is promoting 60 GHz mmWave silicon, systems and software for unmanned aircraft, using wide bandwidth and highly directional beamforming to form line-of-sight, low-latency links that it says are less exposed to jamming, congestion and detection than sub-6 GHz radios. The company says the compact, low-power design fits small-drone size, weight and power limits and can support identification friend-or-foe. Peraso and partner iNTACT showcased the technology at London's UAV Technology Conference on Sept. 21–22.

A Scoop News Group report sponsored by Datadog argues defense agencies expanding AI and autonomous systems need real-time, unified observability across networks, applications, storage and AI workloads, because sprawling distributed data systems create blind spots and slow incident response. It is vendor-sponsored content.

TimeInteract defines a streaming interaction regime for time-series language models: the model keeps ingesting observations, decides for itself when to speak, and keeps reading the stream while it responds. It combines a dual-view streaming encoder, a learned response trigger and decoupled control/generation inference. A new 34.6K-episode StreamTSI dataset spans four capability levels from understanding to adaptivity. The model beats LLM, VLM and TSLM baselines by up to 23.92 points, with near-zero stream stall and up to 2.15× faster inference.

Face/Off renames identifiers in ways that preserve program semantics but make names progressively less informative or actively misleading. Across models and code-comprehension tasks, accuracy drops as naming information degrades, and outputs often follow the meaning suggested by misleading names rather than the program structure. Prompting and fine-tuning interventions do not remove the effect, while type inference, where answers are locally recoverable, is less affected. The result argues for code evaluations that separate lexical shortcuts from semantic understanding.

For cable-like deformable linear objects, a bidirectional LSTM trained on MuJoCo-simulated data serves as the learned dynamics model inside a Model Predictive Path Integral (MPPI) controller. The biLSTM captures the nonlinear, high-dimensional deformation, and MPPI's sampling-based optimization produces the manipulation actions. Simulation and physical experiments are reported as showing accurate and efficient manipulation. The abstract gives no quantitative results or baselines, so the contribution is mainly an application combining learned dynamics and sampling-based MPC.

MAGIC learns task-specific multi-agent collaboration graphs in which each functional role can be instantiated either as a single agent or as a reusable predefined group, rather than fixing one granularity across the organization. A construction policy sequentially picks roles, their granularity and their connections, trained on-policy with potential-based reward shaping from probe-based utility and structural signals so intermediate steps get dense feedback without altering the task return. It beats prior topology generators on eight benchmarks with better inference efficiency, though the abstract gives no margins.

This paper imports formal reliability-theory tools into frontier AI control and applies them to Google DeepMind's defenses against rogue deployment. Depending on how failure domains are shared, the same control stack can give cubic, quadratic or merely linear suppression of rare failures. Birnbaum importance ranks which component improvements buy the most nominal reliability, and prevention layers are shown to change the population on which recovery layers are demanded. The result is concrete guidance on what to separate, improve, measure and test when stacking control measures.

Training-free visual-token pruning usually ranks tokens by importance or redundancy, but controlled interventions show removability also depends on layer depth and on which other tokens are deleted alongside. CoRePrune therefore prunes progressively, refreshing perturbation estimates as visual representations evolve, then re-evaluates whether to rescue candidates conditioned on the current deletion set after visual-text interaction. Across five MLLM backbones on standard images, high-resolution inputs and video it holds up under aggressive budgets; on Qwen3.5 with 128 visual tokens it keeps 90.3% of dense performance while cutting prefill time 51.0%.

Asks whether Tiny Recursive Models that fail at their nominal budget are unfinished or stuck, running attention- and MLP-based TRMs on 1,000 hard Sudoku puzzles for up to 512 recurrence steps instead of 16. Exact-solve accuracy climbs from 59.2% to 87.5% (attention) and 74.4% to 91.9% (MLP), recovering over two-thirds of nominal failures. Latent motion drops sharply after the first solution, and completed states are contractive along the trajectory despite strongly expanding Jacobian directions, a signature termed trajectory-conditioned anisotropic stability and confirmed by perturbation experiments.

After users found that Meta's Muse assistant shared OpenClaw's workspace filenames and near-identical SOUL.md personality-file content, Meta Superintelligence Labs product head Nat Friedman said Muse was built from scratch but heavily inspired by the open-source OpenClaw, adding that its creator Peter Steinberger 'got those things exactly right.' Friedman said he bought hundreds of Mac minis for MSL staff to use OpenClaw and that Muse aims to make an OpenClaw-like agent safe and scalable to billions. Muse recently hit No. 1 on the US App Store.

A Data & Society report based on 18 months of fieldwork and interviews with 44 Pennsylvanians (2024–2026) finds opposition to AI data centers spans NIMBY residents, AI critics, environmental groups and people worried about power bills, property values and developers' use of NDAs, while trade unions are the main supporters. It lands as polls show over 60% of Americans favor limiting new data centers and Data Center Watch counts $68B of projects disrupted in Q2 2026; Gov. Josh Shapiro has since removed data centers from a permitting fast-track.

British neocloud Nscale's IPO filing lists over $103B in contracts, about 85% of it from a $43.8B Microsoft compute deal through 2033 and a $44.6B Anthropic agreement that depends on Nscale securing financing and can be cancelled if it misses 'stringent' milestones. First-half revenue was $140.6M (versus $10.4M a year earlier) with a $1.02B net loss. Nscale plans an NYSE listing reportedly targeting a $35B valuation and a $3B raise, after Nvidia provided $1B in convertible debt this month.

Toby Ord analyzes how multi-agent swarms scale and finds that multiplying the number of agents tenfold delivers less performance than giving a single agent ten times as many tokens. The shortfall compounds over larger scale-ups, so swarms fall progressively further behind single-agent compute scaling. Because swarm members run in parallel, however, they can complete the same task in far less wall-clock time, which makes them worthwhile in settings where a large premium is placed on speed.

Tomasz Tunguz reports replacing about a quarter of the LLM if-then calls in one of his agents with specialized deciders: TypeSafe's Jev, released Sept. 15, and the MIT-licensed SemIf, which process the prompt once and score the allowed answers from output logits instead of generating text. On 98 hand-verified email threads, accuracy rose from 47% for the production generative classifier to 80% for Jev and 82% for SemIf running a frozen Qwen3.5-4B. Jev costs $0.042 per million input tokens with no output charge.

Cristian Trout, Rune Kvist and Rajiv Dattani of the Artificial Intelligence Underwriting Company propose a mutual insurer owned by frontier AI developers, with pooled capital (at least roughly $1 billion of coverage per member) paying for harms any member causes. It would cover catastrophic third-party liability, AI cyber losses and business interruption, require incident notice within 24–72 hours, commission third-party audits and evaluations, enforce minimum testing periods, and suspend or expel members that fail to remediate severe risks, citing nuclear and malpractice mutuals as precedent.

TransBERT pretrains a French life-sciences encoder entirely on machine-translated English text, produced with a scalable translation toolkit (TransCorpus) that yields a 36.4 GB French biomedical corpus. The resulting model reaches state-of-the-art results on French biomedical downstream tasks without any native in-domain pretraining data. The toolkit, corpus, model and code are all released, a practical recipe for domain/language pairs where native text is scarce but translation from English is good.

FeatLens indexes a repository by natural-language feature descriptions linked to function-level entities. For each task it builds a seed graph and prunes it with semantic-structural personalized PageRank, so dependency retrieval needs no persistent whole-repo graph and no LLM exploration. It gets the best DR@15 on DevEval (0.501) and EvoCodeBench (0.460) and the top DIR@1 on DevEval generation (about 53% with DeepSeek-V3.2 or GPT-5-mini) at competitive Pass@1. Versus the strongest graph baseline it uses 61% fewer nodes and 46% fewer tokens.

A Knowledge Pull Request updates a document with new knowledge by extracting claims, routing them to sections, flagging conflicts, and emitting a ChangeLog that keeps the knowledge change separate from the text diff. On cross-lingual Wikipedia revision and RAGTIME report updating, KPRs integrate more new information and preserve more existing content than rewriting or regenerating, and add the most information per generated token. A KPR-revised article also grounds QA better than a frontier model with search, which misses facts documented only in other languages.

TAPe+ML v3 replaces pixel-tensor input with TAPe, a structured representation encoding relations among perceptual elements, feeding a modular system of contour processing, local localization, prototype-based classification and coordinated submodels. The authors report fewer than 100K parameters yet 84.7 mAP50 / 65.3 mAP50-95 on COCO detection, 58.4 mask mAP50-95 on COCO segmentation and 89.9% top-1 on ImageNet-Real. Results at this parameter count are far outside the norm, and the abstract gives little detail on the evaluation protocol.

A new analysis of Oja's algorithm gives near-optimal rates for gap-free streaming PCA, with no eigengap assumption and beyond rank-one updates, plus a nearly matching lower bound. The proof needs only a second-moment bound on each stochastic update rather than the almost-sure bounds used by prior near-optimal analyses, and extends to a Rayleigh-quotient notion of approximate PCA, answering an open question of Jain et al. The main application is gap-free differentially private PCA for sub-Gaussian data, settling a recent conjecture up to log factors.

Drifting yields one-step generative models, but learning stochastic transitions that way normally needs several next-state samples per current state, which trajectory data rarely provide. Block-triangular joint drifting applies a projected drift field to the observable joint distribution of consecutive states; the triangular structure preserves the current-state marginal so the second block directly samples the conditional next-state distribution. The surrogate rolls out stochastic trajectories with one network evaluation per step and shows better accuracy-cost trade-offs than deterministic, diffusion, flow and distillation surrogates.

Under the spiked covariance model, the span of several leading sample eigenvectors carries substantial signal information well before individual eigenvectors converge to the population components, shown via a posteriori subspace-angle bounds from singular-vector perturbation theory. SuperPCA (SUbsPace subsamplER PCA) exploits that approximate eigenspace and needs only a small subset of sampled coordinates, cutting data-acquisition cost when signals are roughly sparse. At equal measurement counts it can be about 10× more accurate than classical PCA in high-dimensional, multi-signal settings.

Characterizes when an n-mode bosonic Gaussian state can be learned as cheaply as a classical 2n-variate Gaussian. Near-vacuum (cold) states are provably non-classical to learn: single-copy tomography needs Ω(n³) copies versus Θ(n²) classically, and the hardness persists with few-copy entangled measurements. When thermal noise exceeds vacuum by ν > 0, single-copy tomography needs Θ(n²·min(n, 1+1/ν)) copies, achieved by simple non-adaptive heterodyne measurements and dropping to the classical Θ(n²) for constant ν. This gives a tight quantum-to-classical crossover in learnability.

A naive port of residual vector quantization to the Poincaré ball fails because Möbius addition is non-associative and straight-through gradients ignore curvature. The fix is hyperbolic residual aggregation, which restores the telescoping sum, plus a discounted hyperbolic straight-through estimator that treats the whole quantizer as one geometric block. On hierarchy prediction, recommendation, image tokenization and neural audio codecs it gives more stable, structured codes than naive hyperbolic baselines. Euclidean RVQ still wins on pure compression, so the method suits hierarchical latents.

MemoryAthena extends Engram-style learned memory tables with two generative pathways: memory generated from retrieved cues, and memory generated from backbone states alone. Direct retrieval stays as the anchor. A small causal router, trained on counterfactual next-token likelihood gains while everything else is frozen, decides when a generated candidate should adjust the retrieval residual, and rejection recovers the direct path exactly. With about 201M memory-side parameters, QA average rises from 37.65 to 39.28 and general NLP from 76.73 to 79.13.

Typed decision models that output one of a fixed set of options always produce schema-valid answers, but this paper shows they can ignore the rubric attached to each option. Swapping the labels on two rubrics from 0/1 to no/yes, with everything else unchanged, flips 70.4 more answers per hundred and moves AUC from 0.94 to 0.23 across 1,200 workflow decisions. Neutral or random-string names avoid the effect, and a hosted model shows it too. Type-error rate stays at 0% throughout, so schema compliance says nothing about semantic correctness.

Behavioral convergence in multi-agent LLM systems is often read as norm emergence, but the same cooperative equilibrium can come from shared expectations, strategic incentives or imitation. This framework also elicits agents' empirical and normative expectations and uses controlled ablations to isolate social learning through interaction and social selection via network-based group formation, then applies adversarial disruption across four LLM families. Eliciting expectations raises cooperation, social learning stabilizes behavior, social selection identifies cooperators but adds little reinforcement, and expectations and coordination recover differently after disruption.

A lightweight CPU detector localizes figures, tables and paratext in scientific PDFs and encodes them as typed-area masks that route tokens to GROBID's specialized models or discard them. On PMC Bioinformatics (1,926 articles) and Materials Science (2,595) it beats plain GROBID on most structural metrics, and on Table-BRGM lifts table-detection F1 from 0.16 to 0.94. Against Docling, MinerU, olmOCR and dots.ocr it has the best paragraph precision and near-best character error rate, at 2.7–3.2x lower cost than the cheapest GPU parser and 10–14x lower than generative ones.

Across 1,773 later-biopsied women and 1,773 matched screen-negative controls, each with at least two prior annual screens, the authors measure how fast frozen breast-level embeddings move along a data-derived cancer direction. In MedImageInsight space, malignant cases drift significantly faster than controls in the two intervals before diagnosis, and Mammo-CLIP and HOPPR show earlier-interval effects; BiomedCLIP, pretrained on literature figures, shows none. Directional embedding velocity thus depends on clinically grounded pretraining and can carry pre-diagnostic signal without task-specific fine-tuning.

Five controlled experiments over 203 Big-Vul functions, three code LLMs (350M–6.7B) and three prompting strategies show compile rate is unreliable for single-function vulnerability repair: about 64% of compile failures stem from harness and dataset artifacts, one compiler-standard flag shifts rates 1.8–2.7x on identical patches, and compiler-feedback loops inflate it via deletion and placeholder non-repairs. Whole-function CodeBLEU also fails, since an unchanged copy of the vulnerable input outscores every model. A change-aware diff_F1 scoring only edited regions gives no-ops zero credit and is offered as a cheap pre-screen, not a quality metric.

A preregistered study showing that conformal abstention guarantees for text-to-SQL depend heavily on which execution oracle supplies the correctness labels. Swapping Spider-Realistic's shipped database for its multi-instance test suite raises held-out risk 2.7–10.2 points above what the certificate's own labels claim, and under blinded expert labels a nominal 0.10 certificate carries 17–20 points of risk. Execution-consistency confidence scores also look better under the oracle that built their clusters in 16 of 16 cases, so scores should be judged by an independent oracle.

Sparse GPs built on fixed basis expansions usually keep the first M basis functions; this paper instead selects the M that matter, using three information-theoretic ranking criteria matched to no-data, no-prior and intermediate knowledge states. Across six UCI regression tasks and three basis families (HSGP, variational Fourier features, variational inducing spherical harmonics), the no-data criterion is a safe default that matches or beats truncation, with large gains for VISH. The data-aware criteria give substantial gains specifically for HSGP, the most widely used family.

TraceVIC identifies vulnerability-inducing commits by reasoning over how vulnerability-relevant code evolves, rather than the git-blame positional heuristics (earliest or latest touching commit) most tools use. It localizes likely root-cause lines, traces their history, and builds temporal graphs linking per-revision program structure through cross-revision correspondence edges, then ranks candidate commits by their contribution to the vulnerable condition. Modeling full history lifts F2 from 0.637 to 0.814; it beats prior methods by up to 28.7% F2 and finds a valid VIC for 78 of 79 vulnerabilities in four unseen C/C++ projects.

The author argues frontier API margins are high enough that AI is absorbing supply chains from other high-margin industries, with memory and fab capacity shifting from consumer devices and bitcoin-mining compute being repurposed. Citing estimates that OpenAI and Anthropic could soon control over 80% of worldwide compute, the post projects that trading firms may accumulate significant compute of their own by 2030.

SoftBank's energy business and nuclear company Holtec delayed listings after investors balked, even as SoftBank's junk-bond raise to fund its OpenAI stake saw healthy demand. Thoma Bravo's Orlando Bravo warned a pipeline of mega-IPOs, including SpaceX, Anthropic, OpenAI and possibly Databricks, could crowd out smaller offerings.

DeepFEAv2 extends a transient finite-element surrogate from structured grids to arbitrary mesh topologies and element types. It orders per-element features into a sequence using the FE connectivity matrix, predicts node- and element-level outputs jointly over time, and adds an FEA-informed regularizer. On structured and unstructured 3D linear-elastic sets and a pressure-driven aortic-valve case it reaches R² up to 0.99, cuts normalized error by up to 87% versus DeepFEA, and runs about three orders of magnitude faster than conventional FEA.

This is the first test of two-stage learning-to-defer on real medical imaging with per-case human reader annotations (Collab-CXR, replicated on VinDr-CXR and CheXpert). With a fixed AI predictor and a trained rejector, the paper adds a third option, deferring to a clinician together with AI guidance. This three-way L2D beats classic two-stage L2D as well as human-only, AI-only and AI-guided-human baselines. Simple losses suffice, rather than the formally derived L2D surrogate losses, which lowers the barrier to human–AI triage in radiology.

This short paper describes an interaction platform for studying how human operators work with heterogeneous autonomous agents in dynamic search-and-rescue scenarios. It is designed to record operator behavior and to plug in existing frameworks for inferring operator intent and supporting decisions. A demonstration shows how autonomous systems could assist the operator's perception, decisions and actions. The abstract reports no quantitative evaluation, so this is best read as infrastructure for future human-robot teaming studies.

Companion to a USENIX Security 2026 Enigma talk, this position paper argues that "policy" in GenAI systems means different things to different practitioners, from model-level alignment to application-level access control. That confusion produces siloed controls that fall short for compliance. It proposes a methodology for dissecting how existing chat and agent systems define and enforce policy, surveys what works and what fails, and ends with recommendations and a call for a unified view of policy enforcement across the stack.

REFLEX routes bounded agent decisions through Jev, a fast typed decision layer, and falls back to a strong LLM only when confidence is low or free-form generation is needed. On a frozen 100-task benchmark it keeps 95% success while cutting strong-model calls by 72.7%, consistently across three fallback model families. Controlled interventions tie reliability to action-set size and near-valid alternatives at authorization boundaries, and on BFCL and tau-style tasks the edge over a cheap generative cascade mostly disappears when ordinary routing is already accurate.

MATES reuses a frozen single-agent policy for multi-agent tasks by learning a small input adapter that maps multi-agent observations, which contain the solo-task information plus identifiable neighbor information, into the format the pretrained policy expects. The policy and the underlying MARL algorithm stay unchanged. On lifelong pathfinding, navigation and cooperative discovery with on- and off-policy learners, it trains only 3.5–7.3% of the parameters of full-policy training, consistently beats MARL from scratch, approaches full fine-tuning and holds up at unseen team sizes.

LACE segments individual tree crowns in 0.1 m/px aerial RGB from bounding boxes alone, using a frozen DINOv3 ViT-L/16 applied at four spatial offsets and interlaced into a denser feature grid, a light CenterNet-style head, and expectation-maximisation that separates recurring crown appearance within boxes from surroundings. Trained on 900 box-labeled images it reaches 0.663 mask AP50 on OAM-TCD, above a mask-supervised Mask R-CNN trained on about 4.2K images (0.626), and 0.691 versus Detectree2's 0.612 on sparse canopy. On NeonTreeEvaluation it matches DeepForest using under 0.1% of its annotations.

This work asks whether a looped estimator, one fitted operator applied repeatedly with shared parameters, beats an untied counterpart with separate per-iteration parameters under the same parameter budget. For general likelihood models it gives an upper bound on squared Hellinger risk for looped sieve MLE and a minimax lower bound for the tuned untied family, exposing a parameter-iteration-accuracy trade-off. Looped residual MLPs and a post-LN Transformer reach minimax rates for Hölder targets with a fixed number of bounded parameters, and at large fixed budgets looped risk vanishes with sample size while untied risk does not.

LOKI joins data-lake tables that share no join keys by using unstructured text as the bridge: a bidirectional cross-attention model learns row and sentence representations under only a global table-text contrastive loss, and fine-grained row-sentence links emerge without local supervision. Those links become interpretable join paths, grouped by relation and materialized as typed integrated tables with sentence-level provenance. It beats multimodal data-discovery baselines and reaches 0.982 macro typed-pair precision at up to 40× lower LLM API cost than direct prompting.

GitScholar links GitHub activity from 444,000 repositories to over 558,000 AI arXiv papers to test code-repository engagement as an early impact signal. Adding GitHub reactions improves early impact-prediction precision by up to 12% over a strong academic baseline; the signal covers nearly all high-impact AI papers and consistently correlates with later academic success. The dataset is released on Hugging Face and is directly useful for paper triage and recommendation systems that cannot wait for citations to accrue.

For kNN anomaly detectors trained only on normal data, the authors derive an AUC lower bound tied to the separation and variances of inlier and outlier scores, and use a local scaling model to attribute score variability to density variation, intrinsic-dimension heterogeneity and domain mismatch. Inlier score variance alone fails as a label-free selection criterion across representations, so they add simple pseudo-anomaly probes as a reference. On DCASE 2022–2025 with four embedding models and 208 candidate systems, diverse pseudo-anomalies make anomaly-free model selection beat standard development-set selection under domain shift.

Label-wise expected calibration error for multi-label classification is poorly measured by existing binning schemes, which underestimate error, merely mirror label frequency, or leave many near-empty bins because negatives dominate. The authors propose a binning scheme that weights positive and negative label assignments equally, producing meaningful calibration estimates in hierarchical and extreme multi-label settings such as medical coding and news topic tagging. They also show that calibrating LLM confidence for multi-label predictions remains an open problem.

ROAM-ASD fuses audio, full-face and fine-grained mouth streams for active speaker detection with a single joint self-attention over all available inputs plus modality-agnostic query tokens, and uses modality dropout so performance degrades gracefully when a stream is missing. It sets new state of the art on five benchmarks: 98.8% mAP on WASD, 87.9% on UniTalk, 96.5% on AVA, 99.3% on ASW and 98.2% on Talkies, gains of 0.9 to 5.1 points over prior bests. It also substantially improves zero-shot cross-dataset generalization.

Alexandru Nedelcu argues against teams that have stopped reading or reviewing code, saying vibe-coded projects degrade into unmaintainable systems because maintainability has no short-horizon metric. He contends that RL for coding has no reward signal for long-term design quality, that current SOTA models refactor poorly (for example, extracting helper functions that are not reusable), and that developers who delegate reading and writing code will not build expert intuition. He predicts companies will advertise 'no-AI' policies as a competitive advantage.

A LessWrong post targets flaws in TinyStories-style datasets used for interpretability research: despite aiming for small vocabularies they contain 40–49K unique words, and 15–24% of words appear fewer than twice. The proposed pipeline enforces a true small vocabulary with guaranteed minimum word frequencies and runs locally on an RTX 5060 Ti.

A new independent effort, B-Side Labs, is building discriminative evaluations, real-time drift detection and interventions for character instability, meaning how far a model's stated values shift under social pressure rather than new evidence. Its first tool, Virtue Council, is live with pilot results, and the project is seeking collaborators.

Announcing a subscriber roundtable, MIT Technology Review summarizes its investigation documenting more than a thousand people who died after moving through areas covered by US border surveillance towers without being reached, some under newly installed AI towers designed to detect people automatically.

Replacing the encoder of a heatmap-based spacecraft pose pipeline with a LoRA-adapted DINOv3 ViT, trained only on synthetic renders, sets the best published SPEED+ results: 1.56° mean rotation error on sunlamp and 1.17° on lightbox, versus 2.66° and 1.75° for EagerNet. Accuracy keeps improving from 300M to 840M parameters with no sign of saturation. The 840M model runs at 133.8 ms per crop at 32 W on a Jetson Orin NX, hardware with orbital flight heritage.

MMAP learns joint image–tabular representations from incomplete clinical records. The image encoder is pretrained with sigmoid contrastive alignment plus generative reconstruction, the tabular encoder builds on a tabular foundation model, and a missing-token generator lets either modality be absent at input. On two longitudinal Alzheimer's tasks, predicting stage conversion and amyloid status, it outperforms strong unimodal and multimodal baselines. The abstract reports no numbers, but the approach targets the missing-modality problem common in medical datasets.

xWhyL reverses the usual XAI direction: instead of generating explanations from causal models, it learns causal models from explanations. A formal theory turns expert explanations into a learning signal that complements observational data and can resolve structures that observational causal discovery alone cannot identify. The authors prove conditions under which misspecified explanations that conflict with the data (the "Causal Tug-of-War") are rejected rather than absorbed. The Causal Interactive Learning instantiation shows efficient expert-guided discovery.

ClusterFewshot picks in-context demonstrations for LLM pipelines by clustering candidates semantically and scoring them for utility, instead of the random sampling or metric ranking used by bootstrap-style optimizers. Inside DSPy pipelines it lowers optimization cost across several benchmarks while improving accuracy over bootstrap-based baselines, both for standalone prompt tuning and for hybrid prompt-plus-weight optimization. The abstract reports no specific numbers, so the size of the cost savings and accuracy gains is not quantified.

S-GDR is an annotation-free synthetic-data pipeline for retraining detectors in high-mix, low-volume automotive manufacturing: a VLM captions a small unlabeled real reference set, SDXL with ControlNet and IP-Adapter synthesizes matching backgrounds, and objects are composited via masks. With a fixed budget of 200 synthetic images it reaches mAP50-95 of 0.739 on a real held-out automotive multi-object test set versus 0.697 for domain-randomized renders, also beating CycleGAN style transfer and unguided diffusion variants at the same budget.

EquivSVA tests whether LLM-generated SystemVerilog assertions capture externally observable behavior rather than quirks of one RTL implementation. It holds 120 behavior families across 12 categories, each with four structurally distinct but equivalent implementations, shared gold properties and three mutants, all passing a 17-job formal validation suite (480 implementations, 914 properties, 360 mutants), with family-safe splits. On the test split only 93 of 293 properties generated by Qwen2.5-Coder-7B-Instruct are formally sound, and soundness varies across equivalent implementations in 14 of 24 families.

Transcription-based CoT for LLM speech translation trains on reference transcripts but conditions on its own transcripts at inference. This work fine-tunes recognition and translation jointly with GRPO, rewarding both the generated transcript and the translation conditioned on it, and compares three token-advantage assignments. With Qwen2.5-Omni-3B across four languages, CoT GRPO beats direct-ST GRPO by 1.77 and 0.83 BLEU on CoVoST 2 and FLEURS, and versus CoT SFT adds 0.82 and 0.67 BLEU while cutting WER by 8.8% and 7.2% relative.

The CHiME-9 ECHI challenge asks systems to extract conversation partners' speech from noisy multi-channel recordings of four-party cafeteria conversations, captured with Meta Aria glasses and hearing-aid microphones and paired with clean enrollment speech. This report reviews seven team submissions, ranked by subjective intelligibility and quality. Top systems substantially improve both over the baseline in listening tests, but objective metrics fail to track listener performance, a gap that matters for evaluating hearing-assistive speech enhancement.

When an evaluation score and its validating proxy label are read from the same text span, their agreement can reflect shared surface cues rather than the intended construct. The authors formalize a validation contract declaring score, span, proxy and construct, and re-evaluate the proxy strictly off the scored span. On HotpotQA with a 50-character prefix, score-proxy agreement exceeds score-correctness agreement by +0.184, shrinking to at most +0.045 beyond 120 characters; on OR-Bench, removing recurring opening templates erases most of a refusal score's proxy association. Only 3 of 11 external studies support the control.

A randomized controlled trial with 50 product designers and 50 product managers measured time savings from Figma Make, an LLM-based prompt-to-design tool, on three standardized design tasks. Among participants who finished, tool access was associated with roughly 20% shorter completion times, with larger gains for product managers than for professional designers. The results suggest prompt-to-design tools mainly let non-designers take on more design work while benefits for designers are task-dependent, extending productivity RCT evidence beyond software engineering.

M.G. Siegler argues that Google, despite owning Gmail, Calendar, Search and Android, has ceded the personal-assistant lead to Meta's Muse, an agent that itself depends on hooks into those Google services. Google's answer, the Gemini Spark agent tab, is still in limited US testing for Ultra and Pro subscribers, while overlapping efforts including the family-focused CC agent, Daily Brief, an AI Inbox for Gmail and AI Mode in Search target the same role. He also notes Gemini 3.5 Pro, promised for June, has not shipped.

Rohit Krishnan examines frontier labs as businesses as OpenAI and Anthropic prepare for IPOs, arguing their moat is a one- or two-model lead over open-weight and Chinese competitors that talent, compute and user data only partly sustain. With enterprises routing spend to cheaper models, he sees three paths: low-margin cloud-style serving, regulatory exclusion of rival models, or expansion into ads, robotics and wet labs. He treats recursive self-improvement as the decisive unknown but expects an automated AI researcher not to unlock it immediately.

Ben Lorica argues agents remove the human buffer that let analytical systems tolerate delay and ambiguity: a procurement agent querying a lagging replica can reorder stock that has already arrived. He outlines what agents need to know mid-task, such as data freshness and authoritative definitions, as design requirements for data platforms.

PP-Net removes scattered light from microscopy and endoscopy images in three stages: a denoiser, a physics-based module that estimates the scattering map and a prior image, and a fusion network that refines it. Progressive synthetic training with cross-domain transfer sidesteps the lack of paired ground truth. Under joint noise and scattering it gains over 10.8 dB PSNR against baselines, cuts NIQE by 43.3% on real W2S images, and runs at about 200 ms per 512×512 image on an INT8 RKNN edge device.

Layer-wise EEG encoding with six CNNs and two ViTs on 200 natural images from ten participants shows opposite depth profiles. CNNs match brain responses best in early layers and decay with depth, while ViTs peak at their deepest blocks, but only if all patch tokens are kept (r = 0.656 for DINOv2, versus about 0.5 for pooled tokens). Matched-architecture and matched-objective controls point to architecture rather than training objective as the cause. The authors suggest CNN classification bottlenecks discard brain-relevant information at depth.

Does transferring a PRNG's full internal state, not just its seed, reproduce identical streams across Python's random, NumPy, PyTorch and TensorFlow? The authors test Mersenne Twister and Philox against reference implementations and find it often does not. Several implementations match, but PyTorch's Philox is fundamentally incompatible with the reference algorithm. The paper gives practical guidelines and user-level workarounds for cross-framework reproducibility, relevant to any ML pipeline that mixes libraries.

GAD-MambaUNet is a compact medical segmentation network whose Direction-Group Graph Selective Scan treats Mamba scan directions and channel groups as graph nodes that exchange information before multi-directional fusion. During training only, a frozen DINOv3 teacher supplies semantic guidance with distillation strength modulated by a gradient-adaptive rule, so inference cost stays low. The authors report a favorable accuracy-efficiency trade-off against lightweight and general segmenters, with ablations supporting both components, but give no headline numbers in the abstract.

Fairness-aware distributed learning upweights high-loss clients, which label-poisoned clients can exploit. FairMean weights client gradients by a bounded, nondecreasing function of local loss, so high-loss clients still get priority but poisoned gradients cannot be amplified without limit. Without poisoning, minimizing the FairMean objective provably favors fairer solutions than average loss; under poisoning, an average-stationarity bound carries an attack term scaling with the square of the poisoned-client fraction. Experiments show lower cross-client accuracy variance and higher worst-client accuracy.

ACERT (Averaged Contextual Emotion Representation through Time) adds a flexible-length window of prior conversational context to speech emotion recognition, which is usually performed per utterance. It surpasses the previous state of the art on IEMOCAP, sets the first context-aware benchmark on SAFE, and posts strong unweighted, class-balanced results on MELD. Ablations attribute the gains to emotional and conversational continuity rather than speaker identity or acoustic conditions, indicating the module tracks emotional flow instead of shortcut cues.

GeoComposer analyzes an image's composition, produces textual guidance, and synthesizes an edited exemplar with better framing and viewpoint while respecting 3D scene geometry, which prior composition editors ignore. Priors from a visual geometry foundation model shape the editing model's intermediate representations to preserve global structure and local correspondences. RL with a hybrid reward then jointly optimizes instruction following, aesthetic quality and geometric consistency. The authors report gains over state-of-the-art composition methods, though the abstract gives no specific numbers.

BELXTR adapts the XTR multi-vector (late-interaction) retriever to biomedical entity linking, adding a task-specific training objective and active query expansion so token-level matches are not averaged into a single vector. Across ten corpora and five knowledge bases it sets a new state of the art on half the corpora, averaging +5 points recall@1. Its largest gains come on cross-species gene disambiguation, where it beats an LLM retrieve-and-rerank pipeline and nearly matches a specialized rule-based system, a cheaper option for PubMed-scale mining.

Coverage Cat, a licensed insurance broker operating in California, Florida, New York, Texas and Washington, is exposing its umbrella and homeowners shopping flows to users' personal AI agents. Agents can discover an MCP manifest, call an umbrella_consumer_prefill tool, or use an OpenAPI-described Agent API with skill docs and sandbox notes, while human shoppers can still use the web intake backed by a licensed brokerage team.

In a TechCrunch interview in San Francisco, Greek Prime Minister Kyriakos Mitsotakis said Greece's under-15 social media ban, starting in January, may already be outdated given AI companions, and that no government is prepared for the speed of AI-driven job displacement. He said policymakers should heed frontier-lab leaders who are unsure how their models self-improve and expects 'smart regulation' largely shaped by the US. He cited an OpenAI teacher-workload pilot, an HPE-built supercomputer in Lavrio, and Microsoft and AWS data center projects in Greece.

Cognition opened in São Paulo and says more than 75% of Itaú's technology teams use Devin, which has documented 300,000+ repositories, migrated .NET services to Java 6x faster and auto-resolved about 70% of security vulnerabilities, while Nubank cut a multi-million-line monolith migration from years to weeks at over 20x lower cost.

For cooperative Dec-POMDPs with unknown, low-rank latent dynamics, each agent learns an approximate low-rank MDP from its private observations plus delayed common information, then plans with least-squares value iteration. There is no centralized coordinator or centralized training. Using team-theoretic equivalence, the authors show each member recovers its component of an approximately team-optimal policy, and they give finite-sample performance guarantees and a sample-complexity bound. The contribution is theoretical and aimed at fully decentralized multi-agent learning.

PROSWIN forecasts hourly solar wind speed four days ahead from EUV images and magnetograms, using a deep network coupled to distributional regression for calibrated uncertainty. A new selection metric, the prediction score, rewards both timeline accuracy and high-speed-stream peaks. Over 14 years it achieves under 1% average calibration deviation, timeline CRPS of 41.0 km/s and peak CRPS of 45.3 km/s. Unlike prior models it does not trade peak accuracy for timeline accuracy, and the 171 Å channel proves a useful complement to 193 and 211 Å.

CF-TDiff recovers the full conditional distribution of missing control outcomes in tensor-valued panel data. It runs conditional diffusion in a low-dimensional Tucker core with a masked score, so nonlinear score learning scales with the product of Tucker ranks rather than of mode dimensions. The authors prove high-probability score-estimation bounds that carry over to distribution recovery. In simulations and Norway's iFlex pricing experiment it beats panel and tensor-completion baselines and gives counterfactual prediction intervals and target-attainment probabilities.

For Bradley-Terry-Luce preference elicitation with parametric multivariate utilities and arbitrary deterministic query designs satisfying joint identifiability, this work derives minimax lower bounds governed by the same Fisher-information geometry as Cramér-Rao. A non-asymptotic score-equation expansion with fixed-point localization gives a design-dependent sample threshold above which the unconstrained MLE exists and is unique with high probability, and splits its error into a linear stochastic term, explicit second-order bias and a remainder. The MLE attains minimax rates up to log factors without compactness constraints or regularizers.

LLM-based procedural character generators, whether prompting directly or adapting persona-bank profiles, yield behaviorally homogeneous populations that endorse positive moral norms and react like helpful assistants. PersonaWeaver separates world building from behavioral specification and conditions behavior on curated, setting-general banks of moral positions and conversational reactions. Across ten realistic and fantastical settings and three LLMs it produces broader moral and interactional response distributions, more varied interpersonal language, length and sentiment, and less archetypal world-attribute combinations than prior methods.

HYDRA handles concept drift in Android malware detection proactively by representing apps as hybrid graphs combining fine-grained control-flow graphs with coarse function-call graphs, then training with a cross-domain contrastive objective that aligns historical and new app distributions using pseudo-labels for unlabeled target samples. This replaces unstable adversarial domain alignment with a single optimization process. On large time-ordered malware datasets it achieves substantially lower false-negative and false-positive rates than prior drift-adaptation methods while needing up to 87.5% fewer labels.

For automatic lip-synchronous dubbing, this TTS model is conditioned on a binary voice-activity track rather than on lip features extracted from video, a lightweight signal that can be produced in several ways. Objective and subjective evaluations show it follows the target speech/silence timing closely while keeping natural prosody and semantically sensible pause placement within sentences. Randomly masking the condition during training makes it optional at inference, so editors can enforce or relax lip-sync constraints per clip.

Builds a hierarchical model of how humans judge scene safety and uses it to create a multi-step reasoning dataset with process-level labels, serving as both a benchmark and a training resource for LLM safety reasoning. A modular process-supervision framework assigns LoRA experts, combined through MoE routing, to individual sub-steps of the reasoning chain, and intermediate steps are analyzed with information-flow and saliency methods. The authors report better interpretability and accuracy than direct scene-to-safety-level mappings, though the abstract gives no numbers.

At its Sept. 22–23 AI Day in Singapore, NVIDIA and partners showcased regional announcements centered on moving government AI from pilots to production, including sovereign and local-language models, developer tooling and infrastructure partnerships across Southeast Asia.

This paper builds a behavior layer over a fixed LLM (Qwen2.5-0.5B) with per-claim confidence, typed provenance, provenance-gated hedging and a persistent belief-revision store, and tests it under pre-registered criteria. Audit guarantees hold, and true corrections are accepted more than false ones (0.44 vs 0.15), but most pre-specified margins fail. A notable negative result: gating expressed doubt on mean token probability ranks correctness below chance (AUC 0.41), while sampling consistency works (AUC 0.66). The claims are carefully limited to a small benchmark.

Target- and multi-speaker extraction models trained on simulated mixtures assume balanced speech activity and enrolment clips that closely match the target speech. Neither holds in real multi-party conversations, where speakers are mostly silent and enrolment audio differs from conversational speech. A new loss that down-weights the dominant silent segments raises STOI from 0.55 to 0.60 and frequency-weighted segmental SNR from 4.35 to 5.12 on real recordings. The authors also analyze how enrolment–target mismatch degrades extraction.

ALPINE is a 22K–35K-parameter few-shot image classifier combining fixed Gabor edge-energy guidance with a windowed, content-adaptive patch locator. Under a matched budget of 250 meta-training episodes and five seeds it beats Prototypical Networks, Relation Networks and MAML in 5-shot accuracy on CIFAR-FS and MiniImageNet with 27–53% fewer parameters, converges faster, transfers better to CUB-200 without retraining, and resists occlusion and translation. Ablations show the patch locator, not the relational tokens, drives performance; comparisons are limited to classic meta-learning baselines.

Targets 6G physical-layer security across diverse wireless scenarios, where per-scenario optimization is too slow and single learned models generalize poorly. Scenario-specific diffusion-model experts with Transformer denoisers learn distributions over secure beamforming and artificial-noise strategies; a lightweight gating network identifies the scenario from engineered channel features, and an attention-based combiner fuses proposals from the top experts to cover unseen scenarios. In simulation the MoE keeps near-optimal secrecy rates across a continuum of scenarios and outperforms single-model baselines.

MICRO (Multi-Fidelity Impact Clustered Rollout) splits a shared annotation budget between cheap quality ratings and costly error annotations to maximize confirmed severe-error discoveries. It jointly models ratings and annotation losses given item features, clusters candidate acquisitions by predicted impact on severity probabilities for diversity, and uses rollout to estimate discovery value. On WMT20 English-German, ratings improve loss reconstruction and severity prediction, and MICRO has the highest mean discovery count across four budget/cost settings, significantly beating all six comparison policies in three of them (p < .001).

The Stanford Review reports that Stanford Residential & Dining Enterprises ran a banner ad built from a staff photographer's photo that had been edited with generative AI: student Billy Ramirez '27 was replaced by an AI-generated woman of a different race, and two other students were altered to appear thinner. Ramirez said he objected to being changed and removed from an image meant to represent him. The paper published the original and edited images side by side.

Google's Android-based Googlebook laptops launch October 4 at prices starting at $899, with preorders now open for five models. Google is positioning them as full computers with premium hardware, on-device apps and developer tooling, and Gemini models are deeply integrated into the software as a core part of the experience.

In an X essay titled 'The great unbundling of intelligence,' Jaya Gupta argues that agent economics are pushing AI applications away from calling a frontier model by default toward capability-level routing, in which judgment, ranking, search and verification are handled by cheaper specialized systems. In this view, frontier models handle fewer but harder tasks, while applications act as 'intelligence compilers' that recombine services efficiently.

Google SVP James Manyika said attitudes to AI are more optimistic in the Global South than in the West, citing Google Translate's new 300-language milestone toward a 1,000-language goal and diagnostics work in Zambia and India targeting undiagnosed tuberculosis.

This paper asks whether logs of what LLM agents chose for users can identify which product improvement the users would actually value. It formalizes a decision-specific audit that turns an observation channel and a value contrast into identified intervals, using standard identification and decision theory. In a frozen 4,800-call study on two pinned model snapshots, all 36 primary intervals stay unresolved. A deterministic extractor resolves 7 of 9 comparisons that model-generated reports leave ambiguous. The recommendation is to keep structured decision-relevant inputs rather than collect more telemetry.

This epistemological review examines BabyLM-style work that uses language models trained on developmentally realistic data as models of infant syntax acquisition. It looks at how corpora are built, which architectures are chosen, how training is done and how syntax is evaluated, and finds methodological assumptions that narrow what these studies can claim about human learning. It also notes that developmentally plausible corpora barely change benchmark results, which points to substantial computational differences between LMs and child learners.

For classifying clear-cell versus non-clear-cell renal carcinoma on contrast CT (KiTS23), the authors compare handcrafted radiomics, CNN, MedicalNet and MedVAE features, alone and fused. A gated fusion of 3D MedVAE and radiomics does best (AUC 82.7%, AP 92.2%) and transfers to TCGA with AUC 79.5%, although only two external negatives were available. Gate analysis shows radiomics dominates, with foundation features acting as case-dependent refinements rather than replacements for interpretable descriptors.

A hierarchical latent-communication module exchanges information through two reduced graphs inside a GENCO-based corrective GNN for multi-grid power-flow prediction. Across three grid topologies and three seeds, Kron-derived transports cut macro family-balanced voltage error from 5.660 to 0.851, 85% below a flat GENCO backbone and 31% below a same-anchor Quotient variant, with one parameter set shared across grids. On two unseen topologies neither hierarchical model yet beats a fitted per-bus mean, so cross-topology generalization remains open; results come from preliminary 200-epoch runs.

This framework scores semiotic alignment between two texts describing the same expression, where a semiotic profile captures both contextual meaning and the discourse references a text makes salient. It yields Semiotic Fidelity (how much of one text's profile the other supports) and Semiotic Coverage (how much of the other's profile it recovers), targeting framing differences that lexical-overlap and whole-text similarity metrics miss. Experiments find coverage generally below fidelity, and LLM-to-human alignment highest at low sampling temperature, degrading as temperature rises.

DIFTA-3D swaps the task-specific Faster R-CNN/ResNet branch of the IIFNet3D RGB-D detector for frozen DINOv3 features delivered through a depth-consistent pipeline: scene points are projected into calibrated frames, filtered by a metric depth-residual check, cached offline and pooled within proposal-aligned RoI grids. A conservative, support-weighted semantic distillation (VAID) on positive RoIs is layered on top. On ScanNetV2 the DINOv3 control scores 76.15/60.93 mAP at IoU 0.25/0.50 and VAID 76.59/62.16; the authors frame this as a transfer recipe rather than a causal attribution.

Short-to-long curricula for speech token language models also change shuffle policy, batch composition, token retention and effective token weights under batch-mean loss, confounding reported gains. Matched comparisons disentangle these factors: with batch composition and token exposure fixed, short-to-long ordering shows no independent benefit, and a perplexity gain from first-epoch length grouping on Mimi disappears under token-balanced loss. Cross-tokenizer results tie the effects to chunk-length variation interacting with token weighting, and the authors offer the protocol for analyzing length-based training.

Arafa is a Modern Standard Arabic fact-checking dataset of 181,976 claim-evidence pairs built by an LLM pipeline that generates claims from Arabic Wikipedia, mutates them into counterfactual claims with refuting evidence, and automatically validates labels as supported, refuted or not enough information. Human raters agree strongly on a sample (kappa 0.89 supported, 0.94 refuted), and automatic validation matches human labels 86–88% of the time. The best of four fine-tuned open transformers reaches 77% macro F1, and the pipeline is designed to transfer to other low-resource languages.

First isolated sign language recognition experiments for Icelandic Sign Language, on ÍTM SignWiki: 1,845 videos over 849 classes, 86% with only two examples, making it effectively one-shot across signers. SPOTER beats OpenHands with ÍTM-only data, and MediaPipe poses beat AlphaPose and SDPose. Cross-lingual transfer dominates: ASL pretraining adds 14–24 points (72.7/47.9/22.6% on 22/117/849 classes), and multilingual training on six other sign languages lifts OpenHands from 1.41% to 28.86% on the full vocabulary.

WaterBERT is a BERT encoder continually pretrained on about 2.97B tokens of water-treatment literature, reaching 90.12% F1 on process classification, 79.50% on NER and 74.04% on relation extraction, ahead of general and domain BERTs. It powers topic modeling over 5,144 ES&T articles and extraction of a structured knowledge graph from 693,211 abstracts at far lower cost than commercial LLMs. A hybrid lexical/dense retrieval system over that graph scores 77.7 relevance versus 54.7–64.5 for text-only baselines.

A-DLCC is a parameter-free clustering method that uses β-integrated local depth to find local centers, points that stay central across multiple locality scales, and ranks them by representativeness. Each center induces a group, group similarity is measured with a new nonparametric group-level local similarity, and a bottleneck-path rule absorbs or bonds neighboring groups only when their contact exceeds a configuration-model null. The rule estimates the number of clusters and when to stop automatically, yielding interpretable partitions on synthetic and real data without tuning.

Shows that the known projection-type correction in deterministic extragradient comes from minimizing an upper bound on distance to a solution, mirroring the classical Polyak step size, and uses this to give a unified analysis of PolyakEG under a local critical condition instead of global Lipschitz continuity, covering Hölder and (L0, L1)-Lipschitz operators and linear rates under strong monotonicity. A direct stochastic variant converges when component operators share a common solution but can fail otherwise; DecPolyakSEG adds decreasing step sizes and provably converges sublinearly without that assumption.

Adapts the threshold of any threshold-type classifier or monitoring rule to a context covariate Z so that conditional label predictions match population conditional distributions, redistributing sensitivity across contexts while holding the overall false-alarm rate fixed. A cheap nonparametric estimator implements it, backed by nonasymptotic error bounds and empirical-process asymptotics that yield uniform confidence bands, functional hypothesis tests and change detection. On a standard credit-scoring benchmark used in interpretable ML, the adapted rule stays easily interpretable and competes with state-of-the-art methods, including transformers.

ai-mode is a GPL-3.0 Emacs package that adds buffer-bound AI chat, multi-candidate inline code completion with adjustable context, code modification and refactoring, documentation generation and bug detection. Backends ship as separate packages for OpenAI, Anthropic, DeepSeek, Hugging Face and Google Generative AI. It manages global, buffer-local and temporary context pools with project-wide indexing and memory files, and logs requests, contexts and responses for debugging and auditing.

An essay maps common concerns about immigration, such as values mismatch, cheap labor undercutting wages and eventual accumulation of power, onto advanced AI agents, arguing the analogy fits AI more closely and with higher stakes, since AI values may be radically alien and systems may outcompete their original beneficiaries.

This benchmark compares supervised transfer learning, uncertainty-based active learning and pseudo-labeling for ground-based cloud classification on GCD, using a frozen ImageNet ResNet50 and label budgets from 1% to 100% over five seeds. Transfer learning alone reaches 0.730 accuracy with 40% of labels versus 0.735 at full labels. Active learning and pseudo-labeling give only small, inconsistent gains: pseudo-labels are accurate (0.95–0.98) but skew toward easy classes, while uncertainty sampling targets confusable ones with little payoff.

DISCO detects overlapping graph communities by biasing sparse multi-head attention with a structural prior from influence-spreading dynamics, so it can reach relevant non-neighbor nodes without message-passing oversmoothing. It trains non-negative community affiliations through a Bernoulli–Poisson edge-reconstruction loss. It is competitive with GCN and GAT baselines across input configurations. A cybersecurity proof of concept uses shifts in community assignment between network snapshots as an interpretable anomaly signal that can be localized to specific devices.

ASTRA-SR restores ground-based planetary images from a single frame, treating denoising, deblurring and super-resolution as one blind problem. Training pairs are synthesized from high-dynamic-range spacecraft RAW images using measured layer-integrated turbulence strengths, moving phase screens, spatially varying exposure-averaged PSFs and sensor noise. The network first denoises while keeping blur, then restores structure at multiple scales and refines high-resolution detail. It improves foreground PSNR by 0.49 dB over the strongest baselines.

In semi-discrete entropic optimal transport, with one finitely supported measure and one sub-Gaussian, the empirical dual potentials converge at parametric rates with no dimension dependence in the leading term, via a tailored strong-concavity analysis of the semi-dual. As a result, the empirical barycentric projection attains squared-error rate 1/n, matching the compact case and improving on the 1/sqrt(n) rate known for fully sub-Gaussian settings. Applied to Sinkhorn-EM on a balanced two-component Gaussian mixture, the iterates are sqrt(n)-consistent for any fixed iteration count, matching classical EM up to a sqrt(log n) factor.

Argues that governance vocabulary for AI agents, such as learning, memory, values, compliance, identity and trust, imports the implicit assumptions of psychology and organizational science, calibrating oversight frameworks to an entity current architectures do not embody. Drawing on Wittgenstein, Kuhn, Haraway and boundary-object theory, the authors identify six epistemological assumptions that break for systems without developmental continuity. The practical output is a six-question Disciplinary Audit for governance documents plus a 37-term taxonomy mapping psychological terms to agent-appropriate operational replacements.

This tutorial formalizes the validation toolkit used for predictive models in general-insurance pricing. It covers graphical tools (calibration plots, actual-vs-expected plots, lift charts, Murphy diagrams) and scoring tools (Bregman and deviance losses, elementary scores, Murphy's decomposition, Gini scores). A central point is whether calibration and discrimination are assessed under a policy-weighted or an exposure-weighted population measure, which decides whether premiums end up calibrated on the right scale. It is aimed at practitioners validating tabular predictive models.

The authors reframe the lexical-semantic relations between NLI premises and hypotheses as higher-level notions of semantic compatibility and incompatibility. The resulting more flexible semantic network is injected to induce alternative reasoning paths in LLMs, which then converge on consistent answers. This exposes and partly fills gaps in models' abstract semantic knowledge, with accuracy gains above 10% for some models, concentrated in the non-entailment class. The authors argue that structured semantic scaffolding, rather than more data or scale, closes these reasoning gaps.

For CT-based clear cell renal cell carcinoma classification in a small labeled cohort, handcrafted radiomics features modulate RenalCLIP foundation-model features via FiLM while also feeding a direct radiomics residual path. The model reaches AUC 0.804 on internal testing and 0.854 on external validation, the best mean AUC among the RenalCLIP fusion strategies compared. Pathway ablations separate the contributions of conditional modulation and the residual, and feature permutation points to tumour texture as the key radiomic signal.

In an OpenAI customer case study, Parallel Web Systems, which builds web-research infrastructure for AI agents, says GPT-6 Astra completed a test task (compiling six labor-market statistics across four states over six months into one report) in half the time of prior models at roughly 50% lower cost with equal quality. Parallel reports that Astra issued more targeted search queries, took fewer steps, and can delegate subtasks to parallel sub-agents.

To counter students photographing graphical assessment problems and submitting them to VLMs, the authors test heuristic, human-interpretable adversarial image transformations meant to degrade model answers. A manual study on circuit diagrams is followed by automated large-scale evaluation on logic-gate topologies and Karnaugh-map coordinate geometry. Stronger VLMs show some robustness, but every model tested is vulnerable to the perturbations. The authors treat such perturbations as a near-term stopgap and argue that assessment design itself must change as VLM capability rises.

Tests whether interpretable stylometric features alone can flag ChatGPT-assisted student writing, using 90 participants who each wrote both independently and with assistance, and grouping each participant's data during validation to prevent leakage. Among eight classifiers, a Random Forest reaches 0.87 ROC-AUC and 0.84 F1 on held-out data, with 22.2% false-positive and 11.1% false-negative rates. SHAP attributes predictions mainly to lexical and grammatical features. The false-positive rate is the practical limitation for academic-integrity use.

Compares handcrafted radiomics, 2D and 3D MedVAE foundation encodings, and their fusion for clear-cell versus non-clear-cell renal cell carcinoma classification on KiTS23 CT under a single preprocessing pipeline. Fusion consistently beats image-only branches, and 3D gated fusion is best at 82.7% AUC versus 79.6% for the best 2D fusion and 74.4% for radiomics alone. Ablations show radiomics and foundation features contribute complementary information, so handcrafted descriptors still add value alongside pretrained representations, especially in 3D.

In a Scaling Laws episode recorded live at Columbia Law School, Lawfare's Kevin Frazier and Chloé Bakalar, ASI ethics lead at the Responsible Superintelligence Institute and a UCL senior research associate, discuss the purposes of political constitutions and how far the US Constitution constrains private power. They then examine AI constitutions: who writes them, whose values they encode, how they are interpreted and revised, and how to verify they constrain a model, before testing a dual structure governing both models and the companies behind them.

Avathon, which builds AI to predict equipment failures and monitor mine and factory safety, signed a five-year partnership with Barrick Gold's North American unit, which Barrick plans to partially list by year-end.

BlameBERT (F1 0.80), a blame-attribution classifier built with an annotation-efficient pipeline for mid-resource languages, is applied to Danish parliamentary speech from 1997 to 2026 and combined with multilevel models. Blame falls until about 2016 and then rises sharply from 2019 onward. Opposition parties blame far more than governing ones, and this effect is moderated by ideology: right-wing and more extreme parties show harder blame rhetoric. The findings hold across classification thresholds.

In a Machine Learning Street Talk short, Alexander Mattick of Fraunhofer IIS and UTN argues that even a perfect world model of chess would not beat Magnus Carlsen, because predicting future states and choosing the right action are separate problems. He uses the distinction to explain why humanoid robots perform backflips on camera yet still fail at mundane tasks such as fetching a carton of milk. The clip is excerpted from a longer MLST interview.

In a FedScoop piece, Intel's Darren Pulsipher argues agencies stumble on AI at scale partly by conflating training and inference hardware needs, attributing the assumption that enterprise AI requires proprietary GPU clusters to CUDA lock-in, and urges agencies to size infrastructure to inference workloads.

U-Net models are trained to segment the aryepiglottic folds, arytenoid cartilages, vocal folds, epiglottis and glottal area in laryngeal high-speed videoendoscopy. The data cover both sustained vowels and connected speech, from normal and disordered voices. Connected speech is the new and harder setting, with large tissue motion and poor fiberoptic image quality, which the authors handle with denoising and histogram equalization. Overall accuracy exceeds 95%, supporting automated quantitative analysis of laryngeal dynamics for voice-disorder assessment.

A preliminary meta-study of end-to-end argument mining pipelines, which turn text into argument structures through task sequences that different works define inconsistently, making comparisons opaque. It reviews several state-of-the-art systems through linguistic, computational and domain lenses, examining how each models argument structure, computes it and injects domain knowledge. The authors also propose a general design for the linguistic and computational perspectives, aiming at method-centered descriptions that make future systems directly comparable.

The authors respond to two critiques of their earlier papers claiming quantum-mechanical statistics in human language and quantum structure in LLM-generated text. They address the exploratory nature of their LLM protocol, the role of marginal-law violations and the Contextuality-by-Default criterion in identifying entanglement, the limited diagnostic value of a standalone Bose-Einstein fit, the assignment of lowest energy levels to the most frequent words, and the relation between LLM embedding spaces and quantum state spaces. A typo in a prior table is corrected without affecting the reported CHSH value.

Replicated simulations of an adaptive agent compare external disturbance, persistent internally generated disturbance and disturbance produced by the controller itself, under regulation-first and disturbance-first update ordering. Persistent internal disturbance yields the largest exposure and regulatory burden in the tested grid. When positive controller updates carry an immediate disturbance cost, raising that cost has a nonmonotonic effect: effective disturbance first rises, run-to-run variability grows at intermediate costs, and corrective activity is strongly suppressed at high cost. The author argues adaptive agents should be tested against distinct disturbance sources.
