LiteLLM

Introduction

LiteLLM is a powerful LLM gateway that acts as an OpenAI proxy, enabling developers and enterprises to unify and manage access to more than 100 large language models (LLMs) through a single integration. By delivering an API format fully compatible with OpenAI’s, it dramatically simplifies the development workflow for multi-model applications, so you never have to wrestle with the differing API conventions of individual vendors.

Key Features

• Unified authentication management: centrally handles API keys and credentials for all LLM providers, including Anthropic, Cohere, Azure, and more.
• Intelligent load balancing: automatically distributes requests across models and providers to keep your applications highly available and performant.
• Spend tracking and budget control: provides detailed cost analytics to help you monitor and manage spending across every model call.
• OpenAI-compatible API: fully adheres to the OpenAI API specification, so existing code can migrate seamlessly without any modifications.

Highlights

• Extreme simplicity and flexibility: abstracts away the complexity of underlying models, letting you call multiple models through a single endpoint.
• Built-in failover and retry mechanisms ensure robust application behavior even when a provider experiences issues.
• Detailed logging and analytics provide powerful support for optimizing both usage patterns and costs.

Who It's For

LiteLLM is the ideal choice for AI engineers, software development teams, and any organization that needs to integrate multiple large language models into their products or services. Whether you are building complex AI applications, running model tests and evaluations, or managing API costs efficiently across an enterprise, LiteLLM delivers significant, tangible benefits.
