Prompt Engineering Guide

Prompt Engineering Guide is a free, open-source knowledge base maintained by DAIR.AI that teaches practical prompting methods for large language models. The site organizes core techniques (e.g., zero-shot, few-shot, chain-of-thought, self-consistency, prompt chaining, ReAct, RAG) with concise explanations and copyable examples. It also includes model-specific guidance (ChatGPT, Claude, Gemini, Llama, Mistral and more), an examples hub across tasks, coverage of risks and misuses, and curated links to papers, tools, notebooks, and datasets. The project is MIT-licensed, translated into multiple languages, and welcomes community contributions via GitHub.
