## AI overview

AI Gateway adds opt-in regional inference that pins requests to the US or EU, verifies the serving region in responses, and fails requests when no provider can serve the selected region. The release also notes regional pricing may be higher.

## Source excerpt

AI Gateway now supports regional inference. Set inferenceRegion on a request to pin it to the US or EU. Every model provider that supports the selected region handles it the same way. Inference runs there, and any data the provider keeps is stored there. AI Gateway supports two pinned regions, plus global routing: If no model provider can serve it, the request fails rather than running somewhere else. Every response reports the region that served it, so you can confirm where each request ran. Here's a request pinned to the US with the AI SDK: Until now, teams with data residency or compliance requirements had to configure regional routing separately for every provider, with no reliable way to confirm where a request actually ran. Regional inference replaces that with a single field that behaves the same everywhere and a response that tells you where each request was served. Filter the model list for models available in the US or EU, or read the regions array from /v1/models. Without inferenceRegion, requests route globally with no residency guarantee, so residency is opt-in. Pinning a region can cost more. The provider sets the regional rate, often around 10% above standard, and AI Gateway passes it through with no markup. For per-provider overrides, response verification, pricing, and BYOK behavior, read the regional inference documentation. Read more
