SOD: Step-wise On-policy Distillation for Small Language Model Agents proposes a new framework that adaptively reweights distillation strength at each reasoning step based on step-level divergence. This approach mitigates cascading errors in tool-integrated reasoning by attenuating misleading teacher signals in high-divergence regions while preserving dense guidance where student and teacher align. Experiments on math, science, and code benchmarks show up to 20.86% improvement over the second-best baseline, with a 0.6B student scoring 26.13% on AIME 2025.

Large language model (LLM) agents are usually improved by changing prompts, models, or hand-written workflows, while the execution harness around the model is treated as fixed infrastructure. We argue that this harness is itself a learnable control layer.

The paper introduces an exploration-guided prompt scaffolding framework for multimodal large language models, dynamically adjusting the prompt distribution during reinforcement learning post-training. It uses an Exploration Potential Score (EPS) derived from KL-regularized policy improvement to assess prompt utility without extra overhead, and a teacher model rewrites low-utility prompts to preserve intent while improving informativeness. Experiments on Geo3K, MMK12, MathVision, and MMMU-Pro show consistent performance gains, up to 9.7% in-domain and over 11% on out-of-distribution benchmarks.
The paper proposes EvalXRL, a benchmark that evaluates explainable reinforcement learning (XRL) methods by measuring how well their explanations help a large language model coding agent diagnose and fix bugs in RL agents. Unlike current metrics that focus on faithfulness or human ratings, EvalXRL uses a closed‑loop, scientific‑method style interaction where the coding agent repeatedly invokes XRL methods, refines hypotheses, and repairs the agent, scoring each method by the resulting RL reward. This approach enables a head‑to‑head comparison of multiple XRL techniques in realistic debugging scenarios.
