Vercel AI Gateway

Vercel AI Gateway is a managed service that provides a unified interface for calling AI models from multiple providers. Developers use it to route requests across different model providers through a single API endpoint, eliminating the need to integrate each provider's API separately. The gateway handles credential management, request logging, spend tracking, routing policies, and automatic failover between providers when one becomes unavailable. It supports various AI modalities including text generation, image generation, embeddings, and reranking across providers like OpenAI and Anthropic.

The service is offered by Vercel and includes observability features for tracking usage and costs. Developers can interact with the gateway through SDKs, REST APIs, or dedicated tools like the AI SDK. The platform provides options for security and compliance, including zero data retention settings and model allowlisting capabilities, enabling teams to centralize their multi-provider AI operations from any infrastructure.
