    Trajectory-Refined Distillation

    • It is the first to formalize the prefix-failure problem in OPD, showing that token-level improvements cannot solve it at the root.
    • TRD performs distillation after refining trajectories within the on-policy support region through trajectory-level refinement.
    • It can be applied to both OPD and OPSD self-distillation and yields consistent gains across the Qwen3 model family.
    • On AMOBench, Qwen3-8B shows roughly 50 percent relative improvement in Pass@16, and the refined trajectories are compressed by about 9 times.
    • This trajectory-level approach outperforms prior token-level loss-improvement methods such as clipping, reweighting, and top-K selection.

    Self-Harness: Harnesses That Improve Themselves

    • It proposes Self-Harness, a paradigm in which the agent improves its own harness through weakness mining, harness proposal, and proposal validation.
    • Across three models, MiniMax M2.5, Qwen3.5-35B-A3B, and GLM-5, the held-out pass rates improve from 40.5% to 61.9%, from 23.8% to 38.1%, and from 42.9% to 57.1%, respectively.
    • Different harness changes are produced for different models, so the updates are model-specific rather than generic instruction additions.
    • A regression-test-based acceptance rule prevents overfitting, and the edits remain small and auditable.
    • The work is directly related to existing harness systems such as SemaClaw and OpenClaw.
    • It is a meaningful step forward in the self-improvement research line for agents.

    LARA: Latent Action Representation Alignment for Vision-Language-Action Models

    • We overcome the limitations of existing separate training pipelines by jointly optimizing LAM and VLA with a bidirectional representation-alignment loss.
    • LAM is grounded in real action trajectories, which suppresses learning spurious visual variations such as background and lighting.
    • VLA is regularized by LAM's forward-dynamics prediction, reducing hallucinated trajectories that are kinematically feasible but functionally wrong.
    • We find that inserting alignment at DiT layer L-2 is optimal, and that alignment in deeper layers is effective.
    • We achieve consistent performance gains on three simulation benchmarks and in a real robot manipulation environment.

    On the Geometry of On-Policy Distillation

    • OPD lies in a relaxed off-principal regime between SFT, which aligns principal components, and RLVR, which localizes non-principal components.
    • The authors discover subspace locking, in which updates lock into a narrow low-dimensional channel soon after training begins.
    • Under a rank-16 projection constraint, OPD preserves performance while SFT degrades sharply, which shows that the locked subspace is functionally sufficient.
    • Token sparsification and off-policy rollouts preserve the rank trajectory, but objective mixing changes it, which confirms that objective composition is the key control axis.
    • Controlled experiments based on Qwen3-8B use multidimensional diagnostic metrics such as update sparsity, spectral drift, and principal-component rotation.

    Continual Learning Bench: Evaluating Frontier AI Systems in Real-World Stateful Environments

    • It is a set of high-quality, expert-validated tasks from six real-world domains, and each task contains latent structure that cannot be solved through pretraining alone.
    • It proposes an evaluation methodology that introduces a gain metric to separate base model capability from experience-based learning.
    • Simple in-context learning (ICL) outperforms dedicated memory systems such as Mem0 and ACE on most tasks.
    • Even the best system reaches only 25.4% normalized gain, suggesting that the continual learning ability of current frontier models is still limited.
    • Memory modules are frequently observed to hurt performance by producing false generalizations and stale beliefs.
    • In terms of cost efficiency, ICL is also superior, and expensive systems fail to deliver proportional gains.

    OneReason Technical Report

    • The paper analyzes the cause of the problem in generative recommendation, where thinking mode fails to outperform non-thinking mode, along two axes: perception and cognition.
    • In pretraining, it obtains strong item-level token perception through an itemic tokenizer and four-granularity training.
    • It uses a three-level cognition-enhanced chain-of-thought, or CoT, SFT scheme that goes from R0, which stands for perception, to R1, derivation, to R2, evolution, and finally R3, recommendation.

    • On TwiFF-Bench, the average score rises from 2.44 to 3.04, and latent span usage increases adaptively as reasoning depth grows.
    • With the same data, text-only SFT reaches only 65.0, whereas interleaved latent SFT reaches 73.2, showing that the gain does not come from extra supervision.

    Flash-WAM: Modality-Aware Distillation for World Action Models

    • It identifies the structural reason why prior consistency distillation fails in video-action joint diffusion: gradient signals vanish because of an asymmetric noise schedule.
    • It selects modality-specific consistency functions, using linear-gradient scaling for actions and variance-preserving parameterization for video.
    • It delivers a 23 times speedup, reducing per-chunk latency from 8.1 seconds to 348 milliseconds and enabling real-time control.

    Reasoning Structure of Large Language Models

    • We build a scalable benchmark based on 21 two-dimensional grid logic puzzles, enabling controlled scaling studies across four difficulty levels.
    • We develop a pipeline that automatically converts unstructured text reasoning traces into atomic claim-dependency graphs.
    • We propose the reasoning efficiency metric eta, a topology-based measure that distinguishes focused reasoning from diffuse search.
    • We empirically show that token count is a poor proxy for reasoning quality, with a correlation of r = -0.05 with eta, and that extra tokens are mostly consumed by verification overhead.
    • Analysis of open-source reasoning models shows that the highest difficulty level is barely solved by any model, even with large token budgets, confirming the limits of simple compute scaling.
    • Early errors are strongly associated with inefficient traces, with r = 0.28, and eta increases when the time of error occurrence is later.

    Why Muon Outperforms Adam: A Curvature Perspective

    • A second-order Taylor expansion decomposes the loss reduction of Muon and Adam. The first-order gains are similar, but the difference appears in the second-order curvature penalty.
    • The update norms are similar, but Muon has lower NDS (normalized direction sharpness), so its curvature cost is smaller.
    • Controlled experiments with Zipf-PCFG show that data imbalance amplifies Muon's NDS advantage.
    • In the middle and later stages of training, Muon's lower NDS comes mainly from reduced within-layer curvature.
    • On heterogeneous-curvature second-order problems, Muon allocates update energy evenly across high- and low-curvature directions.
    • It is rigorously proven that when curvature heterogeneity is sufficiently large, Muon achieves a lower loss than GD.

    OrderGrad: Optimizing Beyond the Mean with Order-Statistic Policy Gradient Estimation

    • We propose an unbiased gradient estimator for order-statistic objective functions, and by changing only the rank weights, it can express many distributional objectives such as VaR, CVaR, trimmed mean, and best-of-K.
    • It is a plug-and-play design that can be applied to existing likelihood-ratio and reparameterization updates in one line of code by reformulating them as reward transformations.
    • Top-M@K shows consistent gains over the existing Max@K, which is the special case max@K with m=1, on both pass@1 and pass@256.
    • Combining a correct-answer reward for Top-M and a length penalty for Bottom-M shortens responses far more effectively than the simple scalarization used by GRPO.
    • Choosing K, the target size, and m, the number of top ranks, controls the exploration-exploitation tradeoff, with larger K improving pass@256 while reducing pass@1.
    • It has effectively negligible overhead, with an O(N log N) sorting cost.

    Latent Reasoning with Normalizing Flows

    • We place a normalizing flow inside the LLM backbone to provide exact likelihoods for continuous CoT while preserving left-to-right decoding and KV-cache support.
    • Continuous thought positions are handled by the NF head, while text positions are handled by the LM head, and both are processed jointly in the same causal stream.
    • The system supports both supervised likelihood training and policy-gradient optimization through a unified interface.
    • Even with Gaussian perturbations in latent space, pass@1 remains nearly unchanged, showing that the learned continuous thought space is locally smooth and functionally robust.
    • On code-generation benchmarks, it improves accuracy while reducing inference cost compared with explicit CoT and prior latent reasoning methods such as LaDiR.

    • It is a large benchmark with 55 subdomains, 13 industry clusters, and 1,490 task instances based on the O*NET and SOC 2018 occupational taxonomy.
    • Tasks are collected from projects already completed by working professionals and are evaluated automatically with deterministic scripts and structured rubrics, removing dependence on human raters.
    • The tasks are classified into three tiers by difficulty, Near-Term with 59 tasks, Full-Spectrum with 55, and Last-Exam with 36, to support agent evaluation at different levels.
    • Failure analysis shows that lack of domain knowledge, meaning understanding and approach, accounts for about 75 percent of all failures, so knowledge is the main bottleneck rather than execution ability.
    • Model choice creates about three times larger performance differences than agent harness choice, and using more resources does not always lead to better performance.
    • Even the strongest configuration, Codex plus GPT-5.5, reaches only a 2.6 percent average pass rate, which suggests that the benchmark is still far from saturated.

    How abundant are good interpolators?

    • It establishes a large-deviation principle for the generalization error when a classifier is chosen at random from the set of interpolating classifiers.
    • It shows that almost all interpolating classifiers concentrate exponentially around the same generalization performance.
    • The analysis is carried out on two natural distributions: Gaussian mixture models and logistic models.
    • In the overparameterized regime, gradient descent and linear programming outperform random interpolators.
    • The result suggests that benign overfitting in practical algorithms is a nontrivial phenomenon rather than something obvious.
