Codeflash is a general-purpose optimizer for Python that uses advanced large language models (LLMs) to automatically generate, test, and benchmark multiple optimization ideas, then creates merge-ready pull requests with the best improvements for your code. Optimize an entire existing codebase by running codeflash --all. Automate optimizing all future code you will write by installing Codeflash as a GitHub action. Optimize a Python workflow python myscript.py end-to-end by running codeflash optimize myscript.py. Optimizing the performance of new code for a Pull Request through GitHub Actions. This lets you ship code quickly while ensuring it remains performant.

Features

  • Automatically generates optimization suggestions with LLMs
  • Validates correctness of optimizations
  • Benchmarks performance to choose the best variants
  • Creates merge-ready pull requests for review
  • Can optimize entire codebases via codeflash --all
  • Integrates as a GitHub Action to optimize future code
