About LiteLLM
LiteLLM is an open-source library designed to simplify and unify interactions with various Large Language Models (LLMs) from different providers, including OpenAI, Azure, Anthropic, Google, Cohere, and many others. It allows developers to call any LLM using a consistent, OpenAI-like API format, significantly reducing the complexity of integrating multiple models into an application. Beyond API unification, LiteLLM offers a robust suite of features crucial for production-grade AI applications. These include automatic retries and fallbacks to alternative models or providers, enhancing application reliability and resilience against API outages or rate limits. It also provides comprehensive cost tracking, enabling users to monitor and manage their LLM expenditures effectively.
Further capabilities include caching to reduce latency and API costs, secure API key management, and support for streaming responses. LiteLLM can also be deployed as a proxy server, offering centralized control over LLM calls, prompt management, and enterprise-grade features like user management and spend limits. Its primary use cases revolve around building multi-LLM applications, mitigating vendor lock-in, optimizing operational costs, and improving the overall reliability and performance of AI-powered systems. The target audience includes developers, machine learning engineers, and data scientists who are building or managing AI applications, as well as enterprises looking for a flexible and robust solution to orchestrate their LLM infrastructure.
