Route requests to the right LLM for cost, latency & quality

Visit WebsiteShare

FastRouter gives developers and enterprise teams a single, unified gateway for all their LLM work. Instead of wiring up each model provider separately, you connect once through an OpenAI-compatible API and FastRouter sends every request to the best model from a pool of 200+ LLMs. It weighs cost, latency, output quality, and reliability in real time, and it handles failover automatically when a provider slows down or errors out. You also get observability into every call and governance controls for your team. The result is that you can scale AI applications without rewriting code or locking yourself into one vendor.
