What is RouteLLM?

RouteLLM is a framework for serving and evaluating LLM routers.

Our core features include:

  • Drop-in replacement for OpenAI's client (or launch an OpenAI-compatible server) to route simpler queries to cheaper models.
  • Trained routers are provided out of the box, which we have shown to reduce costs by up to 85% while maintaining 95% GPT-4 performance on widely-used benchmarks like MT Bench.
  • Benchmarks also demonstrate that these routers achieve the same performance as commercial offerings while being >40% cheaper.
  • Easily extend the framework to include new routers and compare the performance of routers across multiple benchmarks.
