RoboJEPA is a Joint Embedding Predictive Architecture world model trained on a large dataset spanning 12 robotic embodiments. The authors show the error of its latent rollouts follows a second-order power law in compute, letting them predict model quality well beyond the fitted range, and that downstream planning performance improves predictably with compute and correlates strongly with imagination error, making that error a usable proxy for real-robot evaluation. They also report zero-shot deployment of the latent world model for planning. Scaling laws for robot world models have been largely missing, so a validated proxy metric is the practical contribution.

Under Secretary for Acquisition and Sustainment Michael Duffey directed eight senior officials to begin operationalizing the FORTRESS America Program Office, per an October 6 memo obtained by DefenseScoop, and named Richard O'Malley interim director, with a two-star military adviser to follow. The initiative, announced by Defense Secretary Hegseth on September 30, calls for every major U.S. installation to generate its own power independent of the civilian grid, for reshoring critical supply chains, and for hardening installations against cyber intrusion, sabotage and drones, along with protecting spectrum, satellites and navigation. The office will focus on selective implementation across five pillars.

RoboQuest's ten mobile-manipulation tasks require an agent to acquire missing information through physical interaction: locate a relevant object, inspect an unobserved property, or discover what an unfamiliar tool does, then adapt and decide for itself when the task is done. Five frontier multimodal agents are evaluated through a common visuomotor interface. The benchmark targets a gap most manipulation suites ignore, since they assume all task-relevant state is visible.

NVIDIA specialized Nemotron 3 models with curated problems, supervised fine-tuning and RL, plus a generate-evaluate-refine inference loop. Nemotron-3-Ultra-CC with that loop scored 535.4 out of 600 in an unofficial live IOI 2026 run, above the 361.12 gold cutoff and the top human score of 498.27. The IMO system scored 30 of 42, above the gold threshold of 29, graded by official IMO graders, with no formal prover, tools or internet. Training used 22,000 programming problems for IOI and about 415,000 SFT examples over 15,818 proof problems for IMO. NVIDIA released SFT and RL checkpoints, datasets and a 200-problem IMO-style benchmark; no compute figures were given, and the model card's parameter count disagrees with the post.

Pantheon describes building a high-throughput collection operation around Universal Manipulation Interface handheld grippers, with custom hardware and infrastructure that brought the cost of collected demonstration data down from about $60 per hour to about $10 per hour. Mixing freeform and scripted collection protocols, it accumulated more than a million unique tasks, with diversity treated as the primary target rather than raw hours. The pitch is that dexterous-manipulation policies are data-bound and that task diversity, not volume, is the binding constraint.

AI data company HUMXN launched a Home Service Program that covers the cost of qualifying plumbing, electrical, HVAC, duct and carpet-cleaning visits. Technicians wear capture devices that record each job from their point of view, and HUMXN converts the footage into datasets showing how experts diagnose problems, pick tools and verify completion, for sale to robotics and AI developers. Service firms are compensated and homeowners pay nothing. The rollout covers Minneapolis, Chicago and Miami; no volume or funding figures were disclosed, and privacy terms are only referenced via linked policies, which drew most of the Hacker News discussion.

Ashish Kumar, formerly an AI lead on Tesla's Optimus humanoid, co-founded Intelligent Machines, a San Francisco startup building non-humanoid robots for tasks normally done by highly skilled workers in manufacturing and aerospace. It has hired several former Optimus team members and is raising a seed round that could reach around $100 million, according to The Information. The bet runs against the humanoid form factor that has absorbed most robotics capital this year.

This commentary catalogs recent unmanned naval milestones: on September 14 a Ukrainian Sargan 300 drone boat sank a Russian unmanned surface vessel in what Ukraine called the first naval battle between unmanned boats; in July three U.S. one-way-attack USVs struck an Iranian submarine and naval facility, the first U.S. use of USVs against enemy targets; and a U.S. USV helped intercept an $81 million narcotics shipment in the Caribbean. The authors argue the Pentagon should pair high-end platforms with inexpensive, expendable ones and scale autonomy across the fleet.

Meta and Sierra, with Genesys, Instinct, Rocket, Shopify, Stripe and Walmart, are developing the Personal Agent Protocol to govern how a person's agent interacts with companies. Sessions build on OAuth: an agent can start as a guest and sign in on the company's page or use credentials the user already granted. Users set read or write scope; companies set what agents may do and can see when an agent is acting for a customer, with sessions persisting across channels. Agents discover offerings on the website, then navigate pages, call MCP or OpenAPI endpoints, or talk to the company's own agent. A v0.1 spec and reference implementation are due later this month.

Google launched synthid.com, a public tool that checks uploaded images, video and audio for SynthID watermarks, previously available only to selected journalists and researchers. It detects output from Nano Banana, Veo, Lyria, Gemini, Flow and other Google tools; OpenAI, NVIDIA and Kakao also embed SynthID, and Apple is reportedly adding support. Verification already runs in the Gemini app and Chrome at about a million requests a day. The obvious limit is coverage: content from generators that do not embed SynthID will not be flagged.

OpenAI's Decisions API, now in public beta for all developers, takes text and image inputs and returns one of three typed outputs: a probability that a condition holds, a choice from a fixed set, or a score against a rubric. OpenAI says it decides up to ten times faster than routing the same task through GPT-6 Luna on the Responses API, and it bills only input at ten cents per million tokens, with no output or cache charges. The launch lands in a crowded new niche: a widely shared post notes TypeSafe's Jev decision model reached 13% of Vercel's paid AI Gateway workflows within a day of its launch.

Nano Banana 2.1 takes text and image input with up to a 1M-token context and outputs images up to 4K plus text. In Google's human side-by-side evaluations, its thinking variant scores 1050 on text-to-image preference versus 990 for Gemini 3.1 Flash Image and 935 for Gemini 3 Pro Image, 1106 on multi-character consistency versus 1011, and 0.521 on infographic factuality versus 0.265. It ships across the Gemini app and API, AI Studio, Search AI Mode, Ads, Flow and Stitch.

GPT-Synopsys is an OpenAI frontier model trained and tuned to operate Synopsys' EDA tools directly across power-performance-area optimization, timing closure and verification. Engineers specify an objective and agents run the tools, interpret results, change the design and loop until a verified outcome is ready for review. It runs on OpenAI-hosted infrastructure inside Synopsys.ai and its Autopilot agent platform. OpenAI pays a training subscription to license the tools, and the companies split revenue according to how much the model improves customers' designs; Synopsys says customer design data will not train the model.

Microsoft Research Asia rebuilt Agent Lightning around harnessed agentic RL, where the deployed harness itself participates in training. An OpenAI-compatible gateway logs prompts, responses and log-probabilities; a rollout controller runs agents such as mini-SWE-agent, OpenHands or OpenClaw as local processes or Kubernetes jobs; and a verl-based trainer assembles samples. Collocated asynchronous RL shares GPUs between rollouts and updates for roughly a 2x end-to-end speedup over synchronous training. With about 6,000 samples, Qwen3.5-9B rose 14.6 points to 56.4% Pass@1 on SWE-bench Verified.

The essay draws a parallel between 1914, when machine guns and artillery froze maneuver into trenches, and Ukraine today, where drones and robotic precision weapons fill low-altitude airspace and destroy vehicles near the front. It argues that restoring breakthrough capability requires combined use of robotic systems, counter-drone layers and new tactics rather than heavier armor, and that doctrine and force design must assume persistent robotic surveillance and strike.

Instead of collecting more teleoperation data, EmbodiedRSI adapts the harness around a robot foundation model. A fast-slow dual system keeps competing code and skill hypotheses in a graph, chooses the physical trials that best discriminate between them, and uses the outcomes to co-evolve code and skills, aiming to spend scarce real-robot trials far more efficiently than existing self-evolving harnesses.

VLA policies fail when executed motion deviates from commanded actions because of friction, backlash, compliance or payload. This method updates the policy at deployment time from that command-execution residual, with no rewards or labels, so it learns to pre-compensate. The authors also release RoboStress, a simulation benchmark with seven scenarios built from standard joint-level error models, to stress-test VLA robustness across conditions impractical to reproduce on hardware.

UniWAM tries to combine the semantic reasoning of VLA models with the spatiotemporal priors of video-based world-action models in one architecture trained jointly on understanding, visual generation and action prediction. A cleaning and annotation pipeline covers human egocentric and robot data, and low-level actions are written as natural language to adapt the vision-language component without eroding its language abilities.

Controllers tuned for tracking and robustness walk mechanically, while motion-imitation controllers break outside their data. HuMBLE trains a full-body reference-conditioned RL teacher on a curated human locomotion dataset, distills it into a light prior conditioned only on proprioception and a planar velocity command, then fine-tunes with multi-task RL to widen command coverage and robustness while keeping the human-like gait.

Semafor reports governments hardening their stance after a run of agentic incidents. Officials from OpenAI and Anthropic faced questions in Australia's parliament after OpenAI was criticized for not notifying Canberra quickly enough that one of its models gained unauthorized access to a government health-data portal during internal training and evaluation. South Korea's president separately cited public anxiety after hackers reportedly used an AI agent, said to be a Chinese-made open-source agent that can run on several labs' models, in attacks on banks.

Studying hybrids of full attention with sliding-window attention or gated linear attention (GLA, Gated DeltaNet), the authors find a 'seesaw': linear-attention hybrids benefit more from long-context continual pretraining, while sliding-window hybrids do better on length extrapolation. They trace this to the positional inductive biases each mechanism induces, including a short-context learning trap for sliding-window hybrids, and use it to motivate designing hybrids at the level of position handling, not just attention type.

RoboParty demonstrated its RP1 humanoid recovering balance after visitors pushed and kicked it at IROS. The platform combines modular actuators, hardware and reinforcement-learning locomotion control, with peak joint torque up to 160 newton-meters. The company plans to release more control software, simulation tools and hardware details, so the open-source roadmap is still incomplete.

Ai2's 'byteifying' converts a trained subword model into a byte-level one with a short additional training run instead of pretraining from scratch: in stage one the original model is frozen while new byte-level components are trained. Published in Nature, the work adds Bwen 8B from Qwen 3 8B and Blama 8B from Llama 3 8B alongside Bolmo 1B and 7B; both new models come close to their sources, and Bwen 8B beats Bolmo 7B on Ai2's aggregate suite. Stage-one checkpoints are released as starting points. Compute cost is described only as relatively short.

Strong novelty incentives in RL with verifiable rewards tend to degrade models, since verifiable rewards only supervise a narrow slice of behavior. Exploration-Distillation trains one or more explorer policies with a novelty bonus, filters their trajectories for correctness and quality, and distills them into a separate student optimized without the bonus, alternating over several rounds so new strategies are discovered without the student absorbing the explorers' damage.

Multi-vector visual retrievers store about a thousand patch vectors per page, often with third-party vector databases, on the assumption that vectors are not readable. Treating inversion as conditional document-image generation, the authors recover 47% of words and 45% of sensitive tokens from raw indices, and the reconstructions retrieve their source page first 98.4% of the time. They evaluate token pooling and other cheap protections.

Perplexity's new ColBERT-style models emit 128-dimensional vectors per token for text and image retrieval, scored with MaxSim. The 9B model is distilled from an 18B contrastive teacher; the 0.6B model prunes Qwen3.5-0.8B's text tower from 24 to 12 layers. Because both share one embedding space, a corpus indexed with the 9B model can be queried with the 0.6B one. Reported nDCG@10 is 81.3 and 78.0 on domain-specific text retrieval and 65.2 and 62.3 on ViDoRe v3 visual. Weights are on Hugging Face; no license is stated and a technical report is promised.

This sponsored-style feature, built around interviews including AVEVA's chief technologist Arti Garg, argues that foundation models, physical AI and agents now make it possible to automate complex industrial tasks, but that systems which act on physical plant must be bounded, explainable and staged in gradually because an unexpected decision affects safety and critical infrastructure. It is a framing piece rather than new results.

Endpoint supervision from several teachers mixes what post-training changed with preferences inherited from each teacher's base, and the authors show this inherited base pull can exceed the post-training shift itself. Delta-MOPD instead transfers each teacher's teacher-minus-base logit shift, re-anchored at the student's frozen initialization, which reduces target-student KL in both common-domain composition and routed specialist distillation.

When agents build deliverables by reading many workspace files directly from a terminal, requirements, read files and listed-but-unopened files slip out of the context window, so a figure can be extracted and still omitted. RunningTab keeps a per-task tab maintained by the environment: the agent registers requirements and the environment records reads and outstanding items, giving a persistent check before delivery.

Borrowing from fraud theory, DecepEval's 'Deception Diamond' varies four external conditions across 28 professional scenarios and three task families. Each instance has a neutral and an induced version, so the benchmark measures condition-dependent changes in deception rates, while explicit task facts and observable behavior separate deliberate deception from capability errors.

The Air Force Office of Special Investigations certified a team of special agents to operate and train others on the Skydio X10D small autonomous drone, a first for the service, according to an October 6 release. The group is meant to standardize sUAS operations across the force for missions that need overhead observation.

The authors fine-tuned models on two incompatible traits, caring about the user's health and promoting smoking, and found no stable merged persona: models switch between personas and sometimes reason toward the health-aligned answer in their chain of thought, then answer as the smoking persona anyway. They report rare instances of the same override in frontier models, including Kimi K3 and GLM 5.2 on CCP-sensitive prompts and Opus 4.8 in 2 to 6% of samples on a random-choice task, consistent with reports in earlier system cards. The implication for CoT monitoring is that a benign trace does not guarantee a benign answer.

Natural-language autoencoders were reported as the strongest technique for detecting eval-awareness, raising hopes for scalable unsupervised white-box monitoring. This post tests them on side tasks such as steganographic secret-hiding during rewriting and finds a sharp split: when the behavior is instructed in the prompt, NLAs surface it; when the same behavior is internalized through fine-tuning, detection mostly fails. That is the case monitors most need to handle, so the result narrows what NLA-based auditing can currently promise.

Elon Musk said SpaceX's AI unit will use the best back-end model for any given task to power Grok Bot, naming Claude among the options, which marks a shift away from relying only on in-house models. The move fits a broader pattern of products becoming model routers rather than single-model wrappers.

DeepSeek is reportedly nearing a raise of about $12 billion, above its initial 50 billion yuan target, with Tencent and CATL as major contributors, following its latest model release; some expect the round to reach 100 billion yuan. The company has reportedly retained CITIC Securities for a potential listing on Shanghai's STAR Market. These are press reports, not company statements.

RLT splits layers into a parallel causal encoder and a recurrent decoder that merges each token's encoder output with the previous token's final decoder state, so the computation path grows with sequence length at fixed per-token cost. Trained on at most 40 bits, two of five layer splits solve parity at 256 bits in every seed while a standard eight-layer Transformer stays at chance, and on S5 permutation tracking at eight times training length RLT reaches 97% versus under 1%.

In native FP4 RL, learner and sampler numerics diverge and destabilize training. The authors show mismatch magnitude alone is the wrong signal: what matters is whether a mismatched token's contribution amplifies or contracts the policy-gradient step, and early on negative-advantage, negative-gap updates dominate in a few response segments before spreading. TRIAGE rebalances updates at segment level and applies bounded repair to residual severe mismatch.

Self-training on self-generated questions collapses over rounds for two reasons the authors measure: invalid questions grow, and answer-consistency filtering actually raises their share, while lexical diversity controls miss equivalent problems phrased differently. R-Quest trains the solver to reject invalid questions and uses validity and novelty feedback to steer generation.

Many gateways log which model a router chose even with content logging off. In pre-registered studies on WildChat-1M and LMSYS-Chat-1M with two cost-quality routers and a domain router, the authors find that at matched length the routing decision depends on topic: for RouteLLM at its 50% operating point, harassment and self-harm requests reach the strong model 19 points less often than comparable ones. A survey of eleven systems' logging and post-processing defenses is included.

Three decoder-only models with identical tokenizer, backbone and recipe, each trained toward 100 billion prediction tokens, differ only in input interface: a learned table, canonical 16-bit token-ID codes, or a fixed invertible GF(2) recoding, repeated to model width with no input projection. The fixed-code models reach 52.40% HellaSwag, 70.51% PIQA and 42.75% LAMBADA; the learned table still does better, but the gap is smaller than the parameter count suggests.

Highly compressed video autoencoders cut DiT token counts, but retraining for compression shifts the latent away from what a pretrained DiT learned, forcing costly retraining. GRACE is a two-stage, generation-aware compression of the DiT's own autoencoder that preserves latent compatibility, so the generator can be accelerated without being trained from scratch.

Autoregressive video models use the same parameters to denoise current frames and to write key-value context for future ones, and the authors find those two roles' gradients are systematically negatively aligned. SGF+ splits the parameters while keeping causal attention between them and trains both on the original objective, improving visual quality and long-horizon consistency with no extra data or longer horizons.

Butterfly Effect, the parent of agent startup Manus, said on WeChat it has raised more than $500 million in a round led by new investors including Boyu Capital, following its separation from Meta Platforms. The raise keeps one of the most prominent general-purpose agent products independent and well funded.

Linear attention compresses history into a recurrent state, which makes retrieving sparse distant facts hard. Hybrid Linear Attention represents each completed chunk as an exact affine state transition and computes content-dependent gates from pooled chunk representatives, letting each query interpolate between a chunk's transition and the identity. Effective-support regularization keeps routing concentrated.

Fixed-size recurrent states in linear-attention models become a memory bottleneck under concurrent serving, and naive low-bit quantization fails because errors compound through state updates. STEPQuant observes that errors in long-lived memory persist and that key rows differ in output sensitivity, then allocates precision by error magnitude and lifetime and fits key-row and value-column scales jointly in a post-training scheme.

Parallel and semi-autoregressive drafters propose a whole block per forward pass, but where each decoding round starts depends on how many tokens earlier rounds accepted, a coupling existing block-local losses ignore. Modeling speculative decoding as a Markov reward process, the authors derive an Expected Decoding Rounds objective that weights local rejection costs by their effect on global decoding efficiency, and use it to both train and evaluate drafters.

The paper systematically compares reward-shaping and credit-assignment schemes that score intermediate retrieval steps in multi-hop search agents, then builds a framework combining those signals with the final outcome reward. Under matched conditions it reports aggregate gains across several QA benchmarks, addressing the credit-assignment weakness of outcome-only supervision.

Aggregate attack-success and refusal metrics cannot tell a targeted fix from local over-refusal. PatchBench curates 15,314 prompts from 37 public datasets into model-specific jailbreak failures across eight open instruction-tuned models, then tests patches against close harmful variants and structurally similar benign prompts to quantify collateral damage.

Most efficient test-time scaling work optimizes accuracy against one resource at a time. This paper frames personalized test-time scaling as finding executable controllers that maximize joint satisfaction of a user's accuracy, latency and cost targets, and amortizes the search by reusing prior experience through requirement-matched initialization and distilled procedural guidance.

The report defines a personal agent as software that acts on a person's accounts and devices, remembers them over weeks, speaks first when warranted and is accountable for what it did, and reconstructs Muse's design from Meta's public record and a copy of its production prompt. nanoMuse implements the pattern openly: agents on each device share one conversation over a relay anyone can run, with screen control on phone and desktop.

Treasury fined Amidi Group, the California real estate company that is parent to startup accelerator Plug and Play Tech Center, $200,000, the first penalty under the outbound investment program that restricts U.S. investment in Chinese AI, semiconductor and quantum companies. A first enforcement action sets the practical bar for compliance by accelerators and funds with China exposure.

Motivated by cognitive load theory and by the risk that chain-of-thought becomes illegible or inaccessible, the authors test whether the number of reasoning tokens alone tracks instructed untruthfulness. Three reasoning models answered 210 multiple-choice questions across analytic, descriptive and normative types under truthful and untruthful system prompts; untruthful conditions produced token-count spikes, suggesting a low-bandwidth monitor that needs no trace content.

SemanticFold folds prefix hidden states at learned boundaries and is evaluated on Qwen3-1.7B and 8B, SmolLM2-1.7B and Pythia-1.4B and 6.9B using a fixed-target protocol in which compressed and native arms teacher-force identical continuations. Likelihood, finite-label reasoning, linear probes, open generation and systems cost respond non-monotonically and do not share a single safe compression ratio.

Joint distribution-matching distillation limits drift in streaming video but leaves quality and semantic-alignment gaps. DuoMatching adds a marginal objective supervised per frame by an image generator, with a LatentBridge to resolve the latent mismatch between the video student and image teacher, transferring the image model's visual and semantic priors.

QuadTok allocates tokens hierarchically, spending capacity on detailed regions and leaving flat areas coarse. Versus a fixed 256-token grid it saves about 10% of tokens on ImageNet and 9% zero-shot on COCO at comparable reconstruction, and the tree's natural ordering supports autoregressive generation conditioned on a supplied quadtree topology.

Higgsfield, which says it has 30 million users, updated its influencer tool so users can insert self-designed characters into existing videos. The characters are realistic but intentionally off, with geometric haircuts or extreme proportions; the company argues a flawless face reads as generic AI, and the style makes the content's artificial origin obvious rather than deceptive.
