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.
