DemoPSD: Disagreement-Modulated Policy Self-Distillation

arXiv:2607. 02502v1 Announce Type: cross Abstract: On-policy self-distillation (OPSD) has emerged as a practical method for training large language models (LLMs) to reason, where a single model acts as both the teacher and the student with different levels of information access.

RISE: Recursive Improvement via Self-Extrapolating Policy Distillation

RISE (Recursive Improvement via Self-Extrapolating Policy Distillation) is a new method that builds a synthetic teacher from a language model’s own RLVR training trajectory. By extrapolating the displacement between the current checkpoint and a trailing anchor in parameter or logit space, RISE transforms sparse outcome-based updates into dense token-level targets without external models or privileged conditioning. The approach recursively refines the student model, combining RLVR and on‑policy distillation, and demonstrates superior performance across mathematical reasoning, STEM, code generation, and multi‑turn agentic tasks.

Learning from Interaction Experience via Localized Context Distillation

The paper introduces Localized Context Distillation (LoCD), a method that improves learning from interaction experience for large language models. LoCD identifies critical spans in a student’s trajectory that need revision, then has a teacher regenerate only those spans from the student’s own prefix, reducing exposure bias while focusing on informative states. Experiments across math reasoning, code generation, and agent tasks show that LoCD outperforms strong baselines and yields more stable training with smaller, sparser updates.

Trajectory-Refined Distillation

arXiv:2606. 08432v1 Announce Type: new Abstract: On-policy distillation (OPD) has become a central post-training tool for large language models (LLMs), providing dense per-token teacher supervision along the student's own rollouts.
