AI-powered Python performance optimizer that automatically speeds up your code while verifying correctness
Codeflash speeds up Python code by figuring out the best way to rewrite your code while verifying that the behavior of the code is unchanged.The optimizations Codeflash finds are generally better algorithms, opportunities to remove wasteful compute, better logic, utilizing caching and utilization of more efficient library methods. Codeflash
does not modify the system architecture of your code, but it tries to find the most efficient implementation of that architecture.
Codeflash verifies the correctness of the optimizations it finds by generating and running new regression tests, as well as any existing tests you may already have. Codeflash tries to ensure that your
code behaves the same way before and after the optimization.
This offers high confidence that the behavior of your code remains unchanged.
Because Codeflash is an automated process, the main way to use it is by installing it as a GitHub action and have it optimize the new code on every pull request.
When Codeflash finds an optimization, it will ask you to review it. It will write a detailed explanation of the changes it made, and include all relevant info like % speed increase and proofs of correctness.This is a great way to ensure that your code, your teamβs code and your AI Agentβs code are optimized for performance before it causes a performance regression. We call this Continuous Optimization.
