ai-gateway routing model-fallback vercel deployments

AI Gateway routing rules block and redirect models

Apply firewall-style model rewrites and denials at the gateway level—no code changes needed when models fail or get retired.

Summary

Eliminates deploy cycles for model switching. When a model goes down or you need to enforce team policies, a single CLI command applies instantly across all requests using those credentials.

Why it matters

Eliminates deploy cycles for model switching. When a model goes down or you need to enforce team policies, a single CLI command applies instantly across all requests using those credentials.

Implementation verdict

Replaces in-app fallback logic and manual code deployments for model substitution. Requires Vercel AI Gateway and CLI access; works immediately for Rewrite (swap one model for another) and Deny (block requests with 403). Ready now in beta—low friction if already on Vercel stack.

2.When a model goes down or gets retired, you usually have to ship a code change to move off it. With routing rules, you push one rule and every request reroutes instantly
