New framework for LLM agent distillation offers hierarchical control

Researchers have proposed a new framework for distilling interactive Large Language Model (LLM) agents, moving beyond the traditional on-policy vs. off-policy distinction. Their approach introduces a hierarchical distillation method that separates the policy for generating interaction history from the policy for generating action prefixes. Experiments showed that pairing student-induced histories with teacher-generated action prefixes yielded the strongest results, while fully on-policy data became beneficial when mixed with other configurations. The study also found that the timing and pairing of these policies significantly impact performance, suggesting practical guidelines for agent distillation. AI

    Beyond On-Policy vs. Off-Policy: At What Level Should LLM Agent Distillation Follow the Student?

    arXiv:2610.31918v1 Announce Type: new Abstract: Distilling interactive LLM agents requires choosing between teacher-generated demonstrations and student-generated experience, corresponding broadly to off-policy and on-policy distillation. While both have proven effective, we argu…
