Open-source LLM Gateway that standardizes access to 100+ large language models using the OpenAI API format.
Developers and enterprises struggle to integrate and manage multiple large language model APIs from different providers, each with unique authentication, input/output formats, and pricing structures. This fragmentation increases development time, operational complexity, and makes it difficult to switch between providers or implement fallback strategies.

LiteLLM is an open-source LLM Gateway that simplifies how developers and enterprises manage access to multiple large language models. Founded in 2023 and based in San Francisco, LiteLLM has become a trusted infrastructure solution for companies seeking to standardize their LLM integrations across diverse AI providers.
LiteLLM provides a unified interface for calling over 100 large language models from different providers including OpenAI, Anthropic, Azure, Google Vertex AI, AWS Bedrock, and others. The platform translates API calls into the OpenAI format, eliminating the need for developers to learn and implement separate integrations for each provider. This standardization reduces development time and operational complexity when working with multiple LLM providers.
The platform offers several enterprise-grade capabilities designed for production environments. Cost tracking enables organizations to monitor spending across all LLM providers in a centralized dashboard. Load balancing distributes requests intelligently across multiple models to optimize performance and cost. Authentication management provides secure access control through JWT, SSO, and SAML integrations. Rate limiting protects against overuse, while fallback mechanisms ensure service continuity by automatically switching to alternative models if a primary provider experiences issues.
