# Reinforcement Learning from Human Feedback (book)

by [Nathan Lambert](https://rlhfbook.com/)

[Read the original →](https://rlhfbook.com/)

A conceptual path through reward modeling and post-training methods.

Lambert organizes the book around the stages that turn a pretrained model into a useful assistant. It explains the reinforcement-learning background before comparing reward models, preference methods and newer post-training questions.
