On-Policy Distillation shows compute efficiency gains over GRPO

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the compute efficiency of On-Policy Distillation (OPD) compared to Group Relative Policy Optimization (GRPO) for training large language models. While GRPO generally outperforms OPD in accuracy per training FLOPs when using an external teacher, OPD demonstrates significant efficiency gains when trained on its own checkpoints, requiring substantially fewer FLOPs to reach comparable accuracy. The research also highlights that multi-teacher OPD can consolidate specialized GRPO models into a single student, achieving high performance with a notable reduction in total training compute. AI

IMPACT This research could lead to more compute-efficient methods for training large language models, potentially reducing the cost and environmental impact of AI development.

    Unpacking the Compute Efficiency of Strong-to-Weak OPD against GRPO

    arXiv:2611.08453v1 Announce Type: cross Abstract: On-policy distillation (OPD) trains a student on its own rollouts under a frozen teacher's per-token supervision. Does this dense signal reduce the training FLOPs needed to reach a target accuracy compared with reinforcement learn…
