FastRouter.ai is a unified API gateway for teams building and operating AI applications. It provides OpenAI-compatible access to more than 200 models and supports text, image, video, embeddings, and speech workloads. Teams can route requests across models and providers without changing application code, while using virtual model aliases to keep a stable interface as their model configuration changes.
Its core purpose is to centralize model access and operations: model selection, provider routing, failover, cost controls, observability, evaluations, and governance. The gateway can select models using factors such as complexity, domain, and cost, and can retry or fall back when a provider fails. Teams can also compare model outputs and inspect traffic to inform quality and cost decisions.
FastRouter.ai is available as a managed cloud service, with self-hosting available on the Enterprise plan. The site provides a free Starter plan, paid Pro and Business plans, and an Enterprise plan with custom terms.
