Let’s skip the part where I explain what prompt engineering is. You’re here because you’ve already burned hours getting garbage outputs from GPT, watched your token costs spiral, and wondered why the same prompt works beautifully on Monday and completely falls apart on Tuesday.
If you want to read the full guide with all the working examples and detailed explanations, I suggest checking out the original article here: 10 GitHub Repos Every Serious Prompt Write
The difference between developers who ship reliable AI features and those who don’t? They’ve stopped guessing and started engineering their prompts systematically.
These 10 repositories are where the serious work happens. Just the resources that actually move the needle for everyone.
The Knowledge Base
1. dair-ai/Prompt-Engineering-Guide
66k+ stars | The one everyone references for a reason
This is the Wikipedia of prompt engineering, except it’s actually good. DAIR.AI built a complete knowledge system, covering everything from zero-shot basics to bleeding-edge techniques like tree-of-thought and self-consistency.
Three million people have learned from this guide. It’s been cited by The Wall Street Journal and Forbes. Available in 13 languages.

Prompt Engineering Guide
Sponsored by 
Prompt engineering is a relatively new discipline for developing and optimizing prompts to efficiently use language models (LMs) for a wide variety of applications and research topics. Prompt engineering skills help to better understand the capabilities and limitations of large language models (LLMs). Researchers use prompt engineering to improve the capacity of LLMs on a wide range of common and complex tasks such as question answering and arithmetic reasoning. Developers use prompt engineering to design robust and effective prompting techniques that interface with LLMs and other tools.
Motivated by the high interest in developing with LLMs, we have created this new prompt engineering guide that contains all the latest papers, learning guides, lectures, references, and tools related to prompt engineering for LLMs.
🌐 Prompt Engineering Guide (Web Version)
🎉 We are excited to launch our new prompt engineering, RAG, and AI Agents courses under the…
When you’re debugging why chain-of-thought isn’t working or need to explain RAG to your team, this is where you’ll end up anyway. Bookmark it now.
You only need quick templates, not deep understanding.
2. NirDiamant/Prompt_Engineering
22 runnable notebooks | Learn by breaking things
Reading about few-shot prompting is one thing. Running a Jupyter notebook that lets you swap examples and watch outputs change in real-time? That’s how the concepts actually stick.
This repo gives you 22 hands-on tutorials covering the full spectrum — basic prompting, chain-of-thought, self-consistency, prompt chaining, and more. Each technique comes with executable code you can fork and destroy.
You’ll learn more in an afternoon of experimenting with these notebooks than a week of reading blog posts.

The prompt engineering world has split into two camps:
- Camp 1 — Prompt templates: collect system prompts, share copy-paste recipes, curate persona prompts. Useful, but limited.
- Camp 2 — Prompt as engineering: compile LM programs (DSPy), test and regress prompts (promptfoo), control generation structurally (Guidance), optimize prompts automatically (TextGrad, GEPA). This is where the long-term value is.
This repo covers both. The engineering camp gets more space.

6. hwchase17/langchain-hub
Production-ready | For LangChain builders
If you’re building with LangChain, stop writing prompts from scratch. The LangChain Hub organizes battle-tested prompts by use case — summarization, QA, agents, SQL generation — with documentation explaining how to plug them into your chains.
These prompts are designed for production patterns, not demos. Each one comes with context on when and how to use it.
LangChainHub
| 🌐 This repo is getting replaced by our hosted LangChain Hub Product! Visit it at https://smith.langchain.com/hub 🌐 |
|---|
Introduction
Taking inspiration from Hugging Face Hub, LangChainHub is collection of all artifacts useful for working with LangChain primitives such as prompts, chains and agents The goal of this repository is to be a central resource for sharing and discovering high quality prompts, chains and agents that combine together to form complex LLM applications.
We are starting off the hub with a collection of prompts, and we look forward to the LangChain community adding to this collection. We hope to expand to chains and agents shortly.
Contributing
Since we are using GitHub to organize this Hub, adding artifacts can best be done in one of three ways:
- Create a fork and then open a PR against the repo.
- Create an issue on the repo with details of the artifact you would like…
You’re not using LangChain. These prompts work best within that ecosystem.
The Research Stacks
7. promptslab/Awesome-Prompt-Engineering
The academic deep-dive
Want to understand why chain-of-thought works, not just how to use it? This repo curates the research papers that define the field, AutoPrompt, few-shot learning, prompt tuning, reasoning techniques.
It’s dense. It’s academic. And if you’re building anything serious, understanding the foundations will save you from cargo-culting techniques that don’t apply to your use case.

The Power Tools
9. mshumer/gpt-prompt-engineer
Automated optimization | Stop guessing
Here’s the problem with manual prompt iteration, it’s slow, inconsistent, and biased by whatever test cases you happen to remember.
This tool generates prompt variations automatically, tests them against your criteria, and ranks results using an ELO rating system. Prompts compete head-to-head. The best ones rise to the top. No gut feelings required.
For any prompt that runs thousands of times in production, systematic optimization pays for itself immediately. A 5% improvement in accuracy compounds fast.
gpt-prompt-engineer
Be the first to know when I publish new AI builds + demos!
Overview
Prompt engineering is kind of like alchemy. There's no clear way to predict what will work best. It's all about experimenting until you find the right prompt. gpt-prompt-engineer is a tool that takes this experimentation to a whole new level.
Simply input a description of your task and some test cases, and the system will generate, test, and rank a multitude of prompts to find the ones that perform the best.
New 3/20/24: The Claude 3 Opus Version
I've added a new version of gpt-prompt-engineer that takes full advantage of Anthropic's Claude 3 Opus model. This version auto-generates test cases and allows for the user to define multiple input variables, making it even more powerful and flexible. Try it out with the claude-prompt-engineer.ipynb notebook in the repo!
New 3/20/24: Claude 3 Opus -> Haiku Conversion
…You’re prototyping, not optimizing. This is overkill for one-off prompts.
10. langfuse/langfuse
Open-source prompt ops | The production layer
At some point, “I’ll just update the prompt in the code” stops working. You need version control, you need to A/B test changes, or you need to know which prompt version caused that regression last Tuesday.
Langfuse is open-source LLM infrastructure that handles prompt management, observability, and evaluation. Version control your prompts. Test them in a playground before shipping. Track performance across deployments.
Built by a YC W23 team. Self-host or use their cloud. Integrates with OpenAI, LangChain, LiteLLM, and more.
If you’re running prompts in production, you need this layer. The alternative is spreadsheets and prayer.

The Meta-Point
Here’s what separates good developers from great ones where AI is booming, the great ones treat prompting as engineering, not guessing.
They version control their prompts. They test systematically, understand why techniques work, not just how to copy-paste them, and build on the collective knowledge of communities instead of reinventing everything from scratch.
These 10 repositories represent thousands of hours of work from developers who’ve already solved the problems you’re facing, use them.
Your prompts, and your token bills, will thank you.
Did you learn something good today?
Then show some love. 🍭
