What is LLM Proxy?

A server that forwards LLM API requests on behalf of your application, adding features like caching, logging, and failover.

An LLM proxy acts as an intermediary between your application and LLM providers. It can add authentication, rate limiting, caching, and observability without changing your application code. LLM proxies are often deployed as part of an AI gateway solution.

Examples

  • A proxy that adds your OpenAI API key to requests
  • A caching proxy that stores responses for repeated queries
  • A load-balancing proxy that distributes requests across multiple API keys
