What Is LiteLLM?
LiteLLM is an LLM gateway and proxy layer for teams that need to manage authentication, routing, load balancing, and spend tracking across many model providers through one consistent interface. It helps developers keep model access under control instead of hardcoding provider-specific logic across every app.
That makes LiteLLM highly practical for teams building multi-model AI products, internal AI platforms, or production applications that need a cleaner way to work with OpenAI-compatible APIs across many providers.
