Overview

The Prompt Engineering Guide is maintained by DAIR.AI and published both as a website and as an MIT-licensed GitHub repository with more than 77,000 stars, making it one of the largest open AI-education projects in existence. The site is organised into around fourteen top-level sections: Introduction, Prompting Techniques, AI Agents, Guides, Applications, Prompt Hub, Models, Risks & Misuses, LLM Research Findings, Papers, Tools, Notebooks, Datasets and Additional Readings. The Introduction covers LLM settings such as temperature and top-p, the elements of a prompt, and general design tips. The Prompting Techniques section is the core and documents eighteen named methods in a consistent format: zero-shot, few-shot, chain-of-thought, meta prompting, self-consistency, generate-knowledge, prompt chaining, tree of thoughts, retrieval-augmented generation, automatic reasoning and tool-use, automatic prompt engineer, active-prompt, directional stimulus, program-aided language models, ReAct, reflexion, multimodal chain-of-thought and graph prompting. Applications covers fine-tuning, function calling, code generation and synthetic data generation; the Prompt Hub is a browsable library of worked prompts grouped by classification, coding, creativity, mathematics and reasoning; the Models section profiles more than twenty model families. The repository is translated into thirteen languages, and DAIR.AI additionally sells self-paced courses through its academy, but the guide, the notebooks and the paper index are entirely free.

What You’ll Learn

  • Tune temperature, top-p and other settings before blaming the prompt itself
  • Apply eighteen named prompting techniques and know when each one fits
  • Move from zero-shot to few-shot to chain-of-thought deliberately rather than by guesswork
  • Build retrieval-augmented generation and tool-use prompts from documented patterns
  • Recognise prompt injection, jailbreaking and other adversarial misuse patterns
  • Adapt prompts across model families using the per-model guides
  • Use the Prompt Hub's worked examples as starting points for your own tasks

Highlights

  • 77.4k GitHub stars and MIT licensed, so it can be forked as internal training material
  • Each technique links the paper it came from, letting you go straight to the primary source
  • Kept current with new techniques and model releases rather than frozen at 2023
  • Runnable notebooks and a datasets section, not prose alone
  • Available in thirteen languages, which is rare for material at this depth

Who It’s For

Best For

  • Engineers who have been prompting by intuition and want the named techniques
  • Teams writing internal prompting standards or onboarding material
  • Anyone who needs the paper behind a technique, not just the recipe
  • Developers moving an existing prompt set between model families

Prerequisites

  • None for the introduction: it starts from what a prompt is
  • Python and notebook familiarity for the hands-on notebooks
  • API access to an LLM in order to try the examples

FAQ
