Understanding GRPO: Group Relative Policy Optimization in Reinforcement Learning and Large Language Models

The article reviews reinforcement-learning fundamentals and the progression from policy-gradient to PPO, then introduces Group Relative Policy Optimization (GRPO)—a critic-free method that normalizes rewards across multiple sampled outputs to compute group-relative advantages—and shows how DeepSeek-R1 leverages GRPO with rule-based rewards to achieve strong reasoning performance.
