New replay method boosts GRPO training for LLMs

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new method for improving the sample efficiency of GRPO, a reinforcement learning technique used for training large language models. The proposed rollout-level experience replay buffer stores and samples individual rollouts, preventing them from becoming stale and destabilizing training. This approach demonstrated performance gains across various scales of Qwen3-Base models on math benchmarks, with the largest improvement of +4.35 percentage points observed at the 4B scale. AI

IMPACT Enhances LLM training efficiency, potentially leading to faster development and deployment of more capable models.

    Rollout-Level Advantage-Prioritized Experience Replay for GRPO

    Reinforcement learning from verifiable rewards with GRPO is a standard approach for post-training reasoning LLMs. It remains sample inefficient. Each rollout is used for a single gradient update and then discarded. Naive replay is not well suited in this setting because LLM polic…
