Show HN: Achilles – Automatic profiling and C++ optimization of Python via LLMs

5 achennupati 0 5/8/2025, 2:47:26 PM github.com ↗

Hey HN! We built Achilles, a tool that automatically accelerates your Python code. It identifies performance bottlenecks, rewrites those functions in optimized C++, and seamlessly patches them into your running program—without you changing a single line of code.

In CPU-intensive, loop-heavy tasks, we've observed performance improvements of 100-1000x.

Achilles can be installed via pip and works with just a single command.

We'd appreciate your feedback, and feel free to give us a star if you find it interesting!
