LiteLLM

A library and gateway that calls many LLM providers through one OpenAI-style interface.

Definition

LiteLLM is an open-source Python library that normalizes the calling conventions of many LLM APIs — across providers like OpenAI, Anthropic, Cohere, and local runtimes — behind a single OpenAI-compatible interface. It also ships LiteLLM Proxy, a self-hosted gateway that adds logging, rate limiting, budget management, and load balancing on top of any supported provider. It lets applications switch models without rewriting code.
