On-Policy Distillation: Hard Examples Boost LLM Reasoning

A new paper explores the effectiveness of On-Policy Distillation (OPD) for enhancing large language models, particularly focusing on data efficiency and selection. The research found that even a single example (1-shot OPD) can be effective, with harder examples often yielding superior performance gains. The study suggests that improvements stem from longer Chain-of-Thought (CoT) paths in complex problems, which help maintain alignment with the teacher model and teach critical thinking patterns. Based on these findings, a data selection method was proposed that uses only hard examples, achieving performance comparable to a much larger dataset with just 8 selected hard examples. AI

IMPACT Suggests a more data-efficient approach to training LLMs, potentially reducing computational costs and improving reasoning capabilities.

    What Matters in On-Policy Distillation? A Perspective on Data Efficiency and Data Selection

    arXiv:2609.05198v1 Announce Type: new Abstract: On-Policy Distillation (OPD) has emerged as a widely adopted post-training paradigm for enhancing large language models in reasoning domains. However, the data-centric mechanisms in OPD remain relatively underexplored. This paper pr…
