Vercel AI Gateway

The service provides a single API endpoint that lets developers route requests for text, image, and video generation to a wide catalog of AI models from providers such as OpenAI, Anthropic, and others. It handles API key management, unified billing, and observability across the entire stack, allowing applications to switch between models without changing code. Built‑in failover logic automatically falls back to alternative providers when a model becomes unavailable, helping maintain uptime.

Developers can call the gateway with a straightforward SDK or HTTP interface, specifying the desired model and prompt; the gateway forwards the request to the upstream provider and returns the response. Pricing mirrors the upstream provider’s list price with no additional markup, and the platform does not impose its own rate limits, relying on the limits of the underlying services.

The gateway is intended for teams building web applications that need to integrate multiple AI capabilities while simplifying credential handling, cost tracking, and reliability concerns, all within Vercel’s edge‑enabled, serverless environment.
