What does RLHF stand for?

• A. Reinforcement Learning from Human Feedback
• B. Reasoned Learning with High Fidelity
• C. Robust Language Heuristic Framework
• D. Recursive Learning of Human Factors

Answer: (A)

RLHF stands for reinforcement learning from human feedback. The idea is to guide a model’s learning not just with automatic signals, but with judgments from people about which outputs are better. In practice, human evaluators compare or rate model responses, a reward model learns to predict those human preferences, and then the model is fine-tuned via reinforcement learning to maximize that reward signal. This helps the system align with human values and priorities, addressing shortcomings of purely self-supervised training. The other options aren’t standard terms in this context, so they don’t capture the method being described.
