    NatureBench: Can Coding Agents Match the Published SOTA of Nature-Family Papers?

    • It covers 90 carefully selected tasks from 5,500 Nature-family papers across six scientific domains: cell omics, proteins, biological modeling, physical modeling, molecular design, and relational reasoning.
    • NatureGym is an automatic pipeline that builds a containerized task environment directly from a paper, which ensures reproducibility.
    • Even the strongest agent, Claude Opus 4.7, exceeds the published SOTA only 17.8 percent of the time at g greater than 0.1 and matches it 47.8 percent of the time, which shows that the benchmark relies more on translation than discovery.
    • In 45.5 percent of successful paths, the key step was methodological translation rather than scientific invention, meaning conversion into familiar supervised-learning form.
    • The main failure causes are wrong method selection at 45.1 percent and insufficient compute budget at 24.4 percent, not lack of task understanding.
    • An information firewall hides the original authors' methodology, which forces independent discovery instead of reproduction.

    Self-Compacting Language Model Agents

    • Fixed token-threshold compression can trigger in the middle of reasoning or retrieval and accidentally delete verified facts.
    • The method combines a compression tool that the model can call directly with a lightweight rubric that says to compress when a subtask is solved and suppress compression during reasoning.
    • When the tool is provided without the rubric, usage varies widely across models and is often invoked at the wrong time, which shows that the rubric is essential.
    • On math benchmarks such as IMO-Answerbench and HMMT, it improves by up to 18.1 points over the no-compression baseline.
    • On agentic search tasks such as BrowseComp, it improves by 5 to 9 points while reducing token cost by 30 to 70 percent per question.
    • Adaptive compression is possible at inference time alone, without any fine-tuning or external supervision.

    World Action Models: A Survey

    • The survey defines WAM as a model that predicts actionable futures from observation and action history together with task context, and then uses those predictions to generate action.
    • It organizes WAMs along two classification axes: what should be generated, such as rendered, latent, or free, and how the system is decomposed into substrate, backbone, coupling, and deployment.
    • It identifies five core properties: interactability, causality, persistence, physical plausibility, and generalization.
    • It systematically categorizes more than 200 studies into five backbone families: diffusion, autoregressive, joint, optional-future, and related variants.
    • Its core insight is that WAMs are evolving toward a 'generate less, preserve only what is needed for control' design philosophy.

    FAPO: Fully Autonomous Prompt Optimization of Multi-Step LLM Pipelines

    • The Claude Code-based optimization loop follows a pipeline of evaluation, intermediate-step analysis for failure attribution, scoped change proposal, safety review, and verification.
    • The prompt-first strategy prioritizes prompt edits and escalates to chain-structure or parameter changes only when attribution identifies a structural bottleneck.
    • It represents the pipeline as a stateful graph built with LangGraph, and it ensures reproducibility through tenant-isolated workspaces.
    • Across 6 benchmarks and 3 models, meaning 18 comparisons, GEPA wins 15 times with an average gain of 14.1 percentage points, and it wins all 6 structure-change comparisons on HoVer and IFBench with an average gain of 33.8 percentage points.

    VIMPO: Value-Implicit Policy Optimization for LLMs

    • It derives a closed-form expression under the optimality conditions of KL-regularized RL by expressing the value function as a policy-reference log-ratio, which removes the need for a critic.
    • It constructs a critic-free value-optimization objective with a terminal boundary condition V*(s_T) = 0 and a Monte Carlo group estimator.
    • From the same derivation, it obtains a PPO-style actor advantage, separating reward injection through the value loss from policy improvement through the actor update.
    • It shows consistent gains over GRPO on MATH-500, AIME 2024, AIME 2025, and OlympiadBench, with especially large improvements on contest-style problems.
    • It remains consistently better than GRPO even under 25 percent reward-flip noise, showing stronger robustness to reward noise.
    • It validates the method for math RLVR with a 4B base model, and shows that tuning the actor coefficient c_A and value coefficient β determines the tradeoff between learning speed and stability.

    Current World Models Lack a Persistent State Core

    • WRBench defines camera motion as an intervention on observability and evaluates it through a 6-dimensional hierarchical diagnostic chain, from requested-camera to visual integrity to re-observed consistency.
    • Natural-25 uses a design with 25 scene families and four event stages to separate spatial movement from state change orthogonally.
    • Across 23 models and four control paradigms, the common failure is to restore only the state from the time the object was left when the camera returns, without reflecting events that happened while it was unobserved.
    • Scaling Wan from 1.3B to 14B actually worsened re-observed state from 0.66 to 0.62, showing that scaling alone does not solve the problem.
    • LingBot-World has the strongest visible-state consistency, at 0.874 and 0.719, but the lowest requested-camera precision at 0.468, revealing a tradeoff between controllability and state consistency.
    • The key diagnosis is that all public models currently lack what-memory, meaning a record of hidden changes, and an endpoint-persistence training objective.

    HumanScale: Egocentric Human Video Can Outperform Real-Robot Data for Embodied Pretraining

    • Egocentric pretraining shows a clear scaling law, with validation loss decreasing monotonically as more data is added.
    • At the same 5,000-hour scale, egocentric data reduces validation loss by 24% versus robot data, improves in-distribution success from 40% to 92.5%, and improves OOD success from 0% to 90%.
    • The comparison is based on a World-Action Model with a MoT architecture, using a framework that combines video generation and action prediction.
    • Egocentric video has lower normalized jerk, meaning smoother motion, and a lower idle fraction, which makes the data more efficient.
    • In real-robot experiments on an AgiBot bi-manipulator, the egocentric pretraining model maintained a 90% success rate even on OOD objects, while the baseline collapsed to 0%.
    • Robot data shows almost no improvement in unseen-task generalization even when scaled up, demonstrating the fundamental limitations of real robot data.

    Code World Models for General Game Playing

    • The core method uses the LLM not as a policy that directly chooses moves, but as an inductive engine that translates rules and trajectory data into Python code. The generated Code World Model (CWM) is an executable simulation engine that includes state-transition, legal-move enumeration, and terminal-check functions.
    • On top of the CWM, it places MCTS for perfect-information games or ISMCTS for imperfect-information games to perform deep search-based planning. In addition, the LLM is asked to generate a heuristic value function and a hidden-state inference function as code.
    • For imperfect-information games, it proposes a code-based autoencoder paradigm. The inference function serves as the encoder from observation to hidden state, the CWM serves as the decoder from hidden state to observation, and the game rules act as a structural regularizer.
    • It was evaluated on 10 games, five with perfect information and five with imperfect information, including four OOD games newly created for the paper. CWM-MCTS and CWM-ISMCTS performed nearly as well as players based on ground-truth models, and they beat Gemini 2.5 Pro in 9 of the 10 games or tied with it.
    • In perfect-information games, CWM transition accuracy reached 1.0 in most cases, while in imperfect-information games hidden-state inference remained difficult and accuracy dropped to around 52% on the hard game Gin Rummy.
    • The limitations are that learning remains difficult in imperfect-information games with complex rules such as Gin Rummy, and extending the approach to open-world or vision-based games remains future work.

    How Transparent is DiffusionGemma?

    • The paper decomposes transparency into variable transparency, which is how well intermediate states can be understood, and algorithmic transparency, which is how well the process can be reconstructed.
    • Opaque serial depth drops from 28.6 times the initial Gemma 4 level to 1.1 times when mapped to a token bottleneck.
    • Compressing self-conditioning between denoising steps into O(c) tokens causes only a small downstream performance drop.
    • On monitoring evaluation, DiffusionGemma performs about the same as Gemma 4 in terms of CoT monitoring quality.
    • The paper finds diffusion-specific phenomena such as non-sequential reasoning, token and sequence smearing, and intermediate-context reasoning.
    • It provides a framework and benchmark for auditing the transparency of future latent reasoning models.
