## Overview

LiteLLM normalizes model services behind one calling format, as a Python SDK or shared AI Gateway. The proxy manages virtual keys, spend, load balancing and guardrails for switching providers or centralizing access. It is not itself a generative model: connected services perform inference. Check licensing and enterprise-feature scope for the deployed version.
