// How AI learns to be helpful, harmless, and honest from human feedback

💡 The core idea: A raw AI trained only on internet text can be rude, make up facts, or give harmful advice. RLHF (Reinforcement Learning from Human Feedback) is how companies like OpenAI and Anthropic "align" AI to be helpful and safe. Humans rate AI responses, those ratings train a "referee" AI, and then the main AI learns to get high referee scores.

What is RLHF?

RLHF stands for Reinforcement Learning from Human Feedback. It's the secret sauce that turns a raw text predictor into a helpful assistant. ChatGPT, Claude, and Gemini all use some form of RLHF or a similar technique. Without it, AI would just complete text without caring if the answer is correct, helpful, or safe.
