OpenRLHF is an open-source, production-ready framework for reinforcement learning from human feedback (RLHF). It combines a Ray + vLLM distributed architecture with a unified agent-based execution paradigm to enable scalable, extensible RLHF for very large models (70B+ parameters) and supports both single-turn and multi-turn interactions. It provides state-of-the-art RL algorithms (PPO, REINFORCE variants, GRPO, etc.), vision-language RLHF, async training with partial rollout, and production-grade features such as resumable checkpoints, logging, and multi-node deployment.
