Manifold-Aware Exploration for Reinforcement Learning in Video Generation

Mingzhe Zheng, Weijie Kong, Yue Wu +9 authors

Video generation methods face reliability challenges due to complex solution spaces and noise injection during ODE-to-SDE conversion, but a new approach constrains exploration within a learned data manifold to improve stability and quality.

SlopCodeBench: Benchmarking How Coding Agents Degrade Over Long-Horizon Iterative Tasks

Gabriel Orlanski, Devjeet Roy, Alexander Yun +6 authors

Software development is iterative, yet agentic coding benchmarks overwhelmingly evaluate single-shot solutions against complete specifications. Code can pass the test suite but become progressively harder to extend. Recent iterative benchmarks attempt to close this gap, but constrain the agent's design decisions too tightly to faithfully measure how code quality shapes future extensions. We introduce SlopCodeBench, a language-agnostic benchmark comprising 20 problems and 93 checkpoints, in which agents repeatedly extend their own prior solutions under evolving specifications that force architectural decisions without prescribing internal structure. We track two trajectory-level quality signals: verbosity, the fraction of redundant or duplicated code, and structural erosion, the share of complexity mass concentrated in high-complexity functions. No agent solves any problem end-to-end across 11 models; the highest checkpoint solve rate is 17.2%. Quality degrades steadily: erosion rises in 80% of trajectories and verbosity in 89.8%. Against 48 open-source Python repositories, agent code is 2.2x more verbose and markedly more eroded. Tracking 20 of those repositories over time shows that human code stays flat, while agent code deteriorates with each iteration. A prompt-intervention study shows that initial quality can be improved, but it does not halt degradation. These results demonstrate that pass-rate benchmarks systematically undermeasure extension robustness, and that current agents lack the design discipline iterative software development demands.

Rethinking Token-Level Policy Optimization for Multimodal Chain-of-Thought

Yunheng Li, Hangyi Kuang, Hengrui Zhang +4 authors

Researchers developed a token-level reinforcement learning method called PEPO that improves multimodal chain-of-thought reasoning by distinguishing visual grounding from inference through perception-exploration policy optimization.

2Xplat: Two Experts Are Better Than One Generalist

Hwasik Jeong, Seungryong Lee, Gyeongjin Kang +4 authors

A two-expert architecture for pose-free 3D Gaussian Splatting separates geometry estimation from appearance synthesis, achieving superior performance compared to unified monolithic approaches.

RoboAlign: Learning Test-Time Reasoning for Language-Action Alignment in Vision-Language-Action Models

Dongyoung Kim, Sumin Park, Woomin Song +6 authors

A systematic training framework called RoboAlign is proposed to enhance embodied reasoning in multimodal large language models by using zero-shot natural language reasoning and reinforcement learning to improve action accuracy and bridge the gap between language and low-level actions in vision-language-action models.
