arXiv:2606. 11627v1 Announce Type: cross Abstract: Recent work has shown that on-policy distillation can internalize privileged context, such as system prompts or task hints, into a student model so that the context is no longer needed at inference time.

The paper proposes a hierarchical framework for distilling large language model agents, distinguishing between the policy that generates interaction histories and the policy that produces token prefixes for actions. It explores various combinations of teacher-generated and student-generated data across multiple models and environments, finding that pairing student-induced histories with teacher-generated action prefixes yields the strongest training signal, while fully on-policy data is only beneficial when mixed with other configurations. The study also shows that the specific pairing of teacher and student proportions at each level significantly impacts performance, and that strategically front-loading teacher-generated contexts and delaying on-policy contexts improves results.

arXiv:2607. 04763v1 Announce Type: cross Abstract: We study on-policy distillation (OPD) for agentic tasks, where an LLM agent interacts with an environment over multiple turns and a student imitates a teacher over these multi-turn interaction histories.

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.

The paper introduces Validity-Calibrated Reasoning Distillation, a new framework for transferring multi-step reasoning from large language models to smaller ones. Unlike prior methods that rely on static teacher‑student hierarchies and trajectory imitation, this approach treats distillation as a local learning‑signal allocation problem. By comparing the teacher’s and student’s next‑step actions under the same prefix and modulating updates based on their relative local validity, the method provides dynamic, context‑dependent supervision that preserves structural guidance while adapting to local reasoning quality. Experiments on math, code, and instruction‑following benchmarks show that this strategy outperforms strong distillation baselines.
