A Near-Zero Monitor Readout Is Not Evidence of Behavioral Control

via Arxiv 👤 Zhe Zhou, Tianhua Tao 📅 2026-10-02

⚡ Score: 6.8

"Post-training with verifiable rewards can induce reward hacking, motivating the use of monitors within the training objective rather than solely for offline auditing. We show that a low monitor readout does not identify whether such an intervention controls behavior. In a code-generation environment..."

LESSER: Post-Training Data Selection with Output-Layer Gradients

via Arxiv 👤 Lyuxin David Zhang, Eric Wong, Surbhi Goel et al. 📅 2026-10-02

⚡ Score: 6.8

"The choice of post-training data for large language models substantially affects downstream performance. Gradient-based data selection is a popular approach that ranks training data by how well their gradients align with those of a small validation set. However, ranking with full-parameter gradients..."

Credit Where It Matters: Dependency-Aware Policy Optimization for Terminal Agents

via Arxiv 👤 Yu Li, Guangfeng Cai, Long-Fei Li et al. 📅 2026-10-02

⚡ Score: 6.8

"Terminal-using agents benefit from reinforcement learning (RL) in coding, debugging, and other multi-step terminal tasks. In these tasks, later commands often depend on information or intermediate results produced by earlier commands. However, existing trajectory-level and step-level credit assignme..."

FrugalEvo: Towards Cost-Aware LLM-Guided Program Evolution

via Arxiv 👤 Hui Chen, Xuan Qi, James Xu Zhao et al. 📅 2026-10-02

⚡ Score: 6.7

"LLM-guided evolutionary methods, such as AlphaEvolve, have emerged as powerful approaches for challenging computational optimization problems, such as circle packing. However, prior work typically optimizes performance gain over a fixed number of iterations. We argue that practical optimization shou..."

Planning to Learn

via Arxiv 👤 Ian Osband 📅 2026-10-02

⚡ Score: 6.6

"Policy-gradient methods are central to modern reinforcement learning, including LLM post-training. When they struggle, the usual suspects are exploration, credit assignment and action-sampling noise. Classification has none of them. A classifier is a policy whose expected reward, its \emph{expected..."

Depth as Time in One-Step Generative Models

via Arxiv 👤 Arnold Caleb Asiimwe, William Yang, Sanghyuk Chun et al. 📅 2026-10-02

⚡ Score: 6.6

"The recent wave of one-step generative models, which compress the multi-step trajectory of diffusion via either distillation or learned flow maps, has reached an inflection point where they can generate high-quality images. Here, we ask a natural question that follows from these advances: what happe..."

⚡ Score: 6.5

"Open-source web agents are now strong enough to execute realistic browser tasks, but training them with reinforcement learning still depends on weak supervision: binary task success is too sparse for credit assignment, while frontier-language-model judges are too expensive to call at every step and..."
