The GRPO algorithm directly compares the quality of a group of answers to the same question through an intra-group relative reward mechanism, eliminating the need for the separate critic model required by PPO.

UnverifiedGRPO is naturally suited for verifiable tasks, and in scenarios such as mathematics and coding, rule-based rewards can replace complex reward models.69% similarUnverifiedGRPO用组内基线替代传统价值函数估计，通过组内标准化A_i = (R_i - mean(R)) / std(R)计算优势值，省去单独训练价值网络的开销66% similarUnverifiedThe experiment compared four strategies—direct prompting, supervised fine-tuning, chain-of-thought reasoning, and rule generation under GRPO training—and GRPO combined with rule generation achieved the best performance on all four ToM benchmarks.66% similarUnverifiedAfter code is generated, the system automatically runs a test suite, calculates a reward signal based on pass/fail results, and then updates the model parameters using reinforcement learning algorithms such as PPO or GRPO.63% similarUnverifiedD-GRS generates K conditionally independent candidates at each node and tests them sequentially in generation order, with the first candidate that passes the test being selected.63% similar
