Optimize most Python code you write
Codeflash generates several candidate optimizations and presents you with the best-performing candidate. It's more than just "AI suggestions".

298x Speedup for Langflow by eliminating a loop, and deduplicating comparisons. Link to PR
34% Speedup for Pydantic by reducing recursion overhead by managing an explicit stack. Link to PR
89x Speedup by reducing algorithmic complexity by converting a list implementation to set.
148% Speedup for LangChain by not sorting a large array and instead using argpartition. Link to PR
