Vercel AI Gateway Key Features
One API key, hundreds of models
Unified routing, billing, and observability across your entire AI stack — text, image, video, and audio.
Smart routing and failover
Optimize routing for availability, cost, or latency; if a provider degrades, the gateway fails over to the same model on another provider.
Zero markup
Pay provider list prices for tokens — never a cent more — including when you bring your own keys.
Spend control
Budgets at team, project, and API-key level, plus API key management, real-time request logs, and usage analytics.
Drop-in migration
Migrate an existing AI stack by changing the base URL; compatible with the OpenAI SDK and supports bring-your-own keys.
Enterprise security
Zero data retention option, no training on your data, provider allowlist, and Vercel compliance coverage.
