[Vercel AI Gateway](https://vercel.com/docs/ai-gateway) now supports [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules).

Routing rules are firewall-style rules that control which models your team can use, applied at the gateway level instead of in your application code.

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. There are two types:

Type | What it does | Use it to |
| Serves a request for one model using another | Keep traffic flowing when a model is unavailable, migrate off a retired model, standardize on one model, or route an expensive model to a cheaper one |
| Blocks requests for a model | Keep your team off models you haven’t approved |

Rules apply to every request made with your team's AI Gateway credentials. You manage them with the [Vercel CLI](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules#manage-rules-with-the-cli).

Create a rewrite with a source and a destination model. The Gateway swaps in the destination transparently, so your application keeps requesting the source model:

Create a deny rule to block a model. Requests for it return a `403`

:

Rules only change which model serves a request. Everything else you’ve configured still applies to the destination model, including:

**Request-level**: [BYOK], [model fallbacks](https://vercel.com/docs/ai-gateway/models-and-providers/model-fallbacks), [sorting](https://vercel.com/docs/ai-gateway/models-and-providers/provider-filtering-and-ordering), the `only`

[filter](https://vercel.com/docs/ai-gateway/models-and-providers/provider-filtering-and-ordering), and [provider options](https://vercel.com/docs/ai-gateway/models-and-providers/provider-options).

**Team-level**: [Zero Data Retention](https://vercel.com/docs/ai-gateway/security-and-compliance/zdr) and the [provider allowlist](https://vercel.com/docs/ai-gateway/security-and-compliance/provider-allowlist).

Routing rules are in beta. For more information, read the [routing rules docs](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules).
