About

Fast LiteLLM

Fast LiteLLM is an open-source Rust acceleration layer for the LiteLLM Python library, distributed under the MIT license. It's a drop-in extension — install it from PyPI, add one import line, and benefit from Rust-accelerated connection pooling, rate limiting, and token counting with automatic Python fallback.

The source lives on GitHub and the package on PyPI. Issues and contributions welcome.

Neul Labs

Neul Labs is a small consulting and product practice founded by Dipankar Sarkar, focused on production LLM infrastructure: provider routing, proxy operations, latency and cost tuning, and integrating LLMs into existing systems without breaking them. Fast LiteLLM is one of our open-source projects.

We believe in honest benchmarks, deep technical writing, and shipping things that don't make 3am pages worse.
