About
Codeflash is a general-purpose optimizer for Python code that uses LLMs to generate optimization ideas, tests them for correctness and benchmarks them for speed. It then opens merge-ready pull requests containing the best optimization it finds. It runs as a CLI with commands such as codeflash --all and codeflash optimize, and can be added as a GitHub Action with a GitHub app. The site describes a codeflash-agent that runs continuously, with engineers reviewing each change before it ships.
Use cases: coding, refactoring, version-control
