What each one is
Prompt Engineering Guide
DAIR.AI's comprehensive guide to prompt engineering: techniques, patterns, risks, and the research papers behind each of them — not folk wisdom.
- Every technique is backed by a paper
- Covers adversarial prompting and risks
- Available in many languages
OpenAI Cookbook
A collection of working code recipes for LLM tasks — embeddings, RAG, function calling, evaluation. Written for the OpenAI API, but the patterns apply to any OpenAI-compatible endpoint, including your local models.
- Working code, not pseudo-code
- The patterns work with local models too (Ollama, vLLM)
- Covers evaluation, which most guides skip
