About LiteLLM

LiteLLM provides a Python SDK and gateway for calling 100+ language models with OpenAI-style requests and responses. The SDK uses one completion() function across providers including OpenAI, Anthropic, Bedrock and Azure, with streaming, retries, fallbacks and per-call cost reporting. The gateway offers one endpoint for apps in different languages, with virtual keys that carry budgets and rate limits while recording requests and costs.

The same deployment can expose MCP servers and registered agent-to-agent endpoints with per-team access control. It also includes an Auto Router add-on that selects a model by cost for each request, a LiteAgents preview for switching agent harnesses with one parameter change, and a CLI and agent-based controls for managing keys, models and budgets. Single sign-on, SCIM, audit logs of admin changes and multi-region deployment require an Enterprise license.

LiteLLM FAQ

How do I change models in the Python SDK?
Change the model string in completion(); arguments stay the same and output uses OpenAI format.
How does the gateway track spending?
Each app or person uses a virtual key with a budget and rate limit; the gateway records each request and its cost.
How do I use Claude Code or Codex with the gateway?
Sign in with lite login, then start the tool through the gateway; budgets, logs and guardrails apply without individual provider keys.
