What is LiteLLM?

Editorial review

LiteLLM is an AI Gateway designed to simplify the management and access of Large Language Models (LLMs) for platform teams and developers. It acts as a universal API, allowing users to interact with over 100 different LLMs from various providers (like OpenAI, Azure, Gemini, Bedrock, Anthropic, and Hugging Face) using a single, OpenAI-compatible format. This eliminates the need for developers to adapt their code for each specific LLM provider, significantly accelerating development and deployment. The product offers robust features for cost tracking, budget management, and rate limiting, enabling organizations to accurately monitor and attribute LLM usage across teams and projects. It also provides critical functionalities like LLM fallbacks for increased reliability and observability tools for monitoring performance. LiteLLM is ideal for enterprises and platform teams looking to standardize LLM access, control costs, and ensure high availability for their AI applications.
