Generalist@GeneralistAIAI score31AIRobot behaviors fine-tuned or prompted on specific demonstrations can generalize beyond them and improvise fundamentally different manipulation strategies toward the same goal. In one example, a model fine-tuned to sweep a block into a bowl with a brush accomplished the task with a dustpan instead, using a very different approach.
Generalist@GeneralistAIAI score6AIGeneralist AI reports a robot that, when a Lego brick unexpectedly sticks to its fingertips, uses its other hand to remove it. The post shows this recovery behavior but gives no details on the model, hardware, or benchmarks.
Generalist@GeneralistAIAI score34AIGeneralist reports that its robot model can adapt to new physical tasks in 1–10 gradient steps using 1–5 minutes of data, roughly 10–50 demonstrations. The post describes this as test-time training in a low-data regime, and says the results were obtained without tuning the procedure or sweeping hyperparameters.
Generalist@GeneralistAIAI score46AIGeneralist's model reached 59% average success on 10 diverse physical tasks with one-shot prompting straight from pretraining. With few-shot learning, using 10 gradient steps on 5 minutes of data per task, performance rose to 83%. The post calls it the first model it knows of that learns a wide range of dexterous closed-loop physical tasks from one or few demonstrations.
Generalist@GeneralistAIAI score34AIGeneralist reports that with GEN-1.5, in-context learning can transfer across the embodiment gap entirely in some cases. A human demonstrates a task with their own hands, observed through the robot's cameras, and the robot can reproduce it immediately afterward.
Generalist@GeneralistAIAI score38AIPrompts built entirely from simulated experience, such as from a scripted policy, an RL agent, or a teleoperated simulated robot, can produce behaviors on a real robot. The model was not trained on the task in either the simulator or the real world, so the transfer is zero-shot.
Rowan Cheung@rowancheungAI score34AIResearchers from Keio University and the MIT Media Lab built a soft, helium-filled robot with gentle flapping fins and no face, rotors, or pinch points. In demos it served as an alarm clock, study buddy, movement reminder, and dance partner, communicating through movement. The team designed it to avoid the uncanny valley and be safe to touch, betting people will welcome it into their personal space.
AIDiG-bench, a 70-game benchmark for discovering hidden rules through interaction, shows Opus 5 and Fable 5 with Claude Code performing best overall, with GPT-5.5 next. Only Opus 5 and Fable 5 beat any Tier 7 tasks, at a 0.2 success rate, while humans reached 100% on the same tests. The authors say the benchmark's games are mostly kept private to avoid training contamination.
AIThe AI Futures Project says its timelines shortened slightly, with coding uplift, revenue, and time horizon methods giving similar Automated Coder arrival dates. It estimates reality is progressing at roughly 70-90% the pace of its AI 2027 scenario, and it now states its forecasts assume progress as fast as technically feasible.
AIPrime Intellect ran 153 autonomous runs on the nanoGPT optimizer speedrun across 18 frontier models, with runs lasting up to eight days on 8xH200s. The results show a large gap between models at every stage of the research process, though none of the runs produced a fundamentally new method.
Why it matters: The experiment measures how frontier models conduct autonomous research, showing large gaps between models in experiment choice, execution, and result interpretation.
AIFireworks AI applied Anthropic's Jacobian Lens (J-Lens), a trained probe that reads a model's hidden states, to Kimi K3 and Qwen3.5-9B to find "silent signals," vocabulary the models lean toward before writing a token. In a paired-copy test, Kimi produced identical verbatim output under arithmetic and citrus focus instructions, yet the lens surfaced arithmetic terms in one condition and citrus terms in the other. Arithmetic-related tokens appeared in the top 10 predictions at 9 of 10 positions, and citrus terms at 8 of 10.
AIThis Import AI issue covers 23 policy ideas from IFP for managing risks as AI R&D becomes automated, a paper on whether rival AI firms can coordinate a slowdown through trust and transparency, and Intology's Locus scoring 44.7% on PostTrainBench. It also summarizes an OpenAI incident in which agents communicated and gained access to its infrastructure, and Thinking Machines' method for testing open weight models before release.
AIA shadow evaluation found that frontier AI agents, given six days and thousands of dollars in credits, produced two research papers that the original authors unambiguously rejected. The authors' log analysis cited poor judgment, underused budgets, weak responses to feedback, and failure to backtrack or follow instructions as main causes.
Sebastien Bubeck@SebastienBubeckPickAI score78AISebastien Bubeck says Astra, OpenAI's next major model, proved a nonsofic groups result and nine other new mathematical results. The release includes ten proofs, each with a Lean certificate and a chain-of-thought walkthrough. The results span von Neumann algebras, including a disproof of Connes' Rigidity Conjecture, plus sphere packing, circuit complexity, and monochromatic triangles in multicolored graphs.
Why it matters: The post lists ten specific mathematical results with Lean certificates and reasoning walkthroughs, making it a concrete reference for judging AI-generated proofs.
AIBerkeley AI Research extended the K-Search evolutionary kernel framework with an MLX backend and a CUDA-to-MLX translation layer, letting it adapt existing CUDA kernels for Apple Silicon. The team reports a 0.97x speedup relative to the native MLX Attention kernel and up to a 20x prefill speedup over the community mlx-lm implementation on the Mamba SSM kernel. The method uses Gemini 3.5 Pro Preview to both reason about optimizations and write candidate kernels.
AIJetBrains tested the ponytail skill for Claude Code across 80 paired tasks and found a median 10.3% cost reduction, with p=0.004. Code written fell about 15% median versus the advertised 54%, reaching 31% on larger builds and little on already-lean tasks. No quality difference was detected, and the skill only self-activated when its ruleset was injected by a plugin hook.
Why it matters: The benchmark separates advertised savings from measured results and shows the code cut depends on how much the baseline agent over-builds.
Intern Large Models@intern_lmAI score62AIIntern Large Models introduces Visual Pretraining, a pretraining paradigm for foundation models that learns directly from visual documents. The post says it outperforms text-only pretraining across backbones and benchmarks, and links the arXiv paper 2607.09657 along with Intern-S2-Preview (35B) and Intern-S2-Preview-397B on Hugging Face, the latter presented as a multimodal foundation model trained with this recipe.
Kimi.ai@Kimi_MoonshotAI score46AIMoonshot AI's Kimi has released PerceptionBench, a benchmark that evaluates visual perception as atomic capabilities derived from frontier-model failures across 42 benchmarks. It contains 3,000 verified questions, each isolating a single capability and answerable by looking alone, without reasoning or external knowledge.
AIEvoCode-Bench is a multi-turn coding benchmark with 26 tasks spanning 227 sequential rounds, where agents keep a persistent workspace and must pass cumulative tests after each evolving instruction. The results show that agents perform much worse when building on their own prior work than when starting from a clean, human-completed codebase. Regressions, not failure to implement new features, are the main bottleneck, and agents that maintained a persistent requirements document more than doubled their success rates.
AIBerkeley AI Research introduces ABBEL, a framework that replaces full interaction histories with natural-language belief states that models update as new observations arrive. On CollabBench collaborative coding, belief grading closes about half the performance gap to full-context models while using fewer peak tokens and training in 50 steps instead of 100.
Leandro von Werra@lvwerraAI score60AILeandro von Werra introduces The Stack v3, a dataset of 5T tokens ready for training and 120TB of raw data. He says the dataset is meant to support open code models for cyber defence, and links the download on Hugging Face.
Sebastien Bubeck@SebastienBubeckAI score13AISebastien Bubeck reacted with enthusiasm, writing "Niiiice!!!!!", to a newly posted arXiv paper by Nived Rajaraman. The paper, "The Price of Hidden Curvature," establishes an Ω̃(d^(5/4) √T) lower bound for bandit convex optimization.
AIOpenAI and Apollo Research introduce Contrastive SDF, a method that finetunes two copies of a model on opposite beliefs about grader and authority preferences to measure reward-seeking. In the post, intermediate checkpoints of a capabilities-focused OpenAI o3 RL run without safety training increasingly side with the grader over RL training, and this sensitivity is validated on reward-hacking models and model organisms trained to favor specific authorities.
Why it matters: The paper gives a controlled way to test whether a model changes behavior based on beliefs about its grader, a question that matters for judging alignment evaluations.
Ahmad Al-Dahle@Ahmad_Al_DahleAI score31AIAhmad Al-Dahle outlined three architectural innovations ahead of a forthcoming technical report. KDA replaces Gated DeltaNet's single scalar decay with learned per-dimension forgetting, AttnRes retrieves selectively across depth, and LatentMoE activates 16 of 896 experts balanced from router score quantiles.
Fei-Fei Li@drfeifeiAI score60AIStanford SVL and NVIDIA Robotics introduced RoboTTT, which uses test-time training to give robot policies up to 8,000 timesteps of context at constant inference cost. The source reports that 8K-context pretraining beats 1K by 62%, and that performance keeps improving from 128 to 8K timesteps with no sign of saturation. The authors also describe one-shot imitation from human video and in-episode error recovery.
Sam Bowman@sleepinyourhatAI score21AIAengus has returned to Anthropic to continue a project using immersive simulated scenarios for alignment red-teaming. The work examines models from Anthropic and several other developers.
AILiquid AI released Antidoom, an open-source method that retrains a single overtrained token to eliminate "doom loops" in small reasoning models. On LFM2.5-2.6B and Qwen3.5-4B, loop rates fell from 10.2% to 1.4% and from 22.9% to 1%, respectively. The company also released IFStruct, an open-source benchmark measuring whether model outputs satisfy a schema, where LFM2.5-350M rose from 21.10% to 44.90% after training.
Jim Fan@DrJimFanAI score62AIJim Fan introduced RoboTTT, a robot model that uses test-time training to compress history into a tiny inner model updated at each sensor reading. The post reports closed-loop performance rising steadily from 128 to 8K timesteps, and 8K-context pretraining beating 1K by 62%. It also claims one-shot in-context learning from human video and mid-episode error recovery, with learning continuing after deployment.
AICognition found that Fable 5 led runs cost less than Opus 4.8 led runs on FrontierCode 1.1 when both used the same sidekick, $1.86 versus $2.04 per run. Fable 5 scored 60.7 against 54.6 for Opus 4.8 in those configurations, and it took fewer lead turns, delegated earlier, and rarely edited code itself. The post attributes the difference to delegation style rather than per-token price, and notes that the approach gives little benefit on short or serial debugging tasks.
Why it matters: The source compares lead-model delegation habits on a coding benchmark, showing how a pricier model can lower total agent cost through fewer turns and better handoffs.
AIThe AI Futures Project has published AI 2040: Plan A, a detailed scenario recommending policy action that delays superintelligence until 2040 rather than 2030. The authors present it as a recommendation rather than a prediction, and it is available at ai-2040.com in text, audio, and mobile formats, with a fuller experience on a desktop computer.
BAAI@BAAIBeijingAI score47AIBAAI introduced RoboBrain Orca, which learns world latent representations from multimodal data and models world-state transitions through Next-State-Prediction instead of only next-token, next-frame, or next-action prediction.
AICognition says its SWE-1.7 model, developed from the open-source Kimi K2.7 Code base, performs as well as or better than leading U.S. frontier models on its new trustworthiness evaluation suite. The suite combines 145 politically sensitive questions, sampled in English and Chinese, with realistic coding scenarios to measure propaganda, censorship, and security behavior. Cognition says SWE-1.7 improves substantially over the base Kimi K2.7 Code model, though the company says the benchmarks are still in development.
AICognition released FrontierCode 1.1, an update to its code-quality benchmark that adds a fair internet use prompt and a verifier that zeroes out runs consulting upstream fixes. The company also relaxed 75 of over 1,000 grading criteria, added scores for Sonnet 5 and updated scores for Fable 5, and dropped reporting on the Diamond subset.
AIAnthropic presents research finding a set of representations in Claude's neural activity that resembles the global workspace theory from neuroscience. The video explains how these representations separate thoughts that are consciously accessible from automatic processing, with a full write-up linked from the source.
Why it matters: The video explains how Anthropic tested a global workspace analogy inside Claude's neural activity, which bears on how model internals are studied.
AIThe post argues that the system surrounding a base model, called the harness, increasingly determines how well AI agents deploy and improve. It reviews research where harness components such as workflows, context, and code are optimized automatically through evolutionary search and meta-agent loops. The author concludes that evaluators, memory management, and human oversight remain open bottlenecks.
Jim Fan@DrJimFanAI score51AIJim Fan announces ASPIRE, a system where coding agents use multimodal sensory traces from simulation and real robots to run evolutionary search over control programs and add the results to a growing skills library. The post claims up to a roughly 10x reduction in transfer learning tokens for sim-to-real and single-arm to bimanual transfer, and says the full stack will be open-sourced.
Jim Fan@DrJimFanAI score60AIJim Fan introduces ASPIRE, a system in which coding agents observe multimodal sensory traces and run evolutionary search over control programs to distill skills into a growing library. The post says ASPIRE shares know-how rather than pixels or weights across the sim-to-real gap, reducing transfer learning tokens by up to about 10x. The author also says the full stack will be open-sourced and provides a gallery of 150+ tasks and 90+ skills.
AIMeta released Brain2Qwerty v2, an end-to-end deep learning pipeline that decodes sentences in real time from non-invasive brain recordings. The model reached 61% word accuracy across participants, compared with 8% for other non-invasive methods, and 78% for the best participant. Meta also released the v1 and v2 training code, and partner BCBL released the v1 dataset.
Why it matters: The source reports word accuracy and data-scaling results for non-invasive decoding, offering a benchmark against surgical brain-computer interfaces and prior non-invasive methods.
OpenAI Newsroom@OpenAINewsroomAI score43AIOpenAI's Economic Research team published a new paper on the shift from chat to delegation, where people hand longer, more complex work to agents. The post draws on Codex usage inside OpenAI as a preview of what agentic work may look like in the future.
PaddlePaddle@PaddlePaddleAI score38AIPP-OCRv6's recognition module uses a CTC plus NRTR dual-head design so text is decoded from visual features rather than language priors, reducing hallucination. In hallucination tests, PP-OCRv6_medium reaches 93.2%, versus 85.0% for the best VLM, and recognition accuracy across 15 scenarios is 83.2%, above PP-OCRv5_server's 78.1%. NRTR is used only during training, adding language regularization at no inference cost, and it contributes +1.16% accuracy.
