What is mshumer/gpt-prompt-engineer - GitHub?
mshumer/gpt-prompt-engineer is an open source prompt engineering toolkit that generates, tests, and ranks candidate prompts for a task you define. You describe the use case, supply test cases, and the notebooks create multiple prompt variants, run them against every test case, and sort results with an ELO rating system starting at 1200. It ships as Jupyter notebooks you can run in Google Colab or locally.
Most prompt tools help you write one prompt at a time. gpt-prompt-engineer treats prompt selection like a tournament: dozens of candidates compete on your test cases, and the highest ELO scores surface the winners. Separate notebooks cover classification tasks, Claude 3 Opus with auto-generated test cases, and Opus-to-Haiku conversion for cheaper inference. Optional Weights & Biases and Portkey logging trace each run.
ML engineers, prompt engineers, and AI developers use it when they need reproducible prompt tuning instead of manual trial and error. The repo has 9.7k GitHub stars and runs on your own OpenAI or Anthropic API keys. It is free under the MIT license.
PromptPerfect

What is PromptPerfect?
PromptPerfect helps you improve your AI prompts for better results with models like GPT-4, ChatGPT, Midjourney, and Stable Diffusion. It offers prompt engineering to refine your inputs, optimization to boost performance, and debugging to fix issues. You can also host your text and image prompts for free, making deployment simple without extra setup.
Note that PromptPerfect will be discontinued after September 1, 2026, following Jina AI's acquisition by Elastic. ai for AI search and embedding solutions going forward.
