What problem does it solve?
It removes the complexity of calling multiple AI providers by providing a unified, production-ready routing layer that handles provider failover and usage visibility.
Core Features & Use Cases
- Unified model routing via provider/model strings: Use a single API entry point to access many models across providers without provider-specific wiring.
- Failover and provider selection controls: Configure provider order, allowed providers, and fallback models to keep requests working when a provider degrades or fails.
- Cost and operations guardrails: Apply per-user rate limiting, tagging for budget attribution, and caching strategies to control latency and spend.
- Observability and audit logging: Use Vercel’s AI Gateway logs for debugging, compliance support, and usage analysis.
Quick Start
Configure your project to use Vercel AI Gateway with OIDC by linking the Vercel project and running vercel env pull, then call models using the format provider/model such as openai/gpt-5.4 (optionally wrapped with gateway()).
