Short answer
Reinforcement learning from human feedback (RLHF) is a training method in which humans rank AI model outputs, and those rankings train a reward model. The reward model is then used to tune a large language model toward responses people judge more helpful, accurate, and safe. It is a common step in making chat assistants usable.
