Proximal Policy Optimization Algorithms
by OpenAI · free · Last verified 2026-03-17
PPO introduces a clipped surrogate objective that constrains policy update step sizes, achieving the stability of trust-region methods (TRPO) with the simplicity and scalability of first-order optimizers. It quickly became the dominant RL algorithm for training large language models with human feedback.
