## Why Included

AI Gateway can pin inference and retained provider data to the US or EU, giving agent builders one residency control with per-response verification across supported providers.

## Source Summary

AI Gateway now accepts **inferenceRegion** to pin supported requests to the **US or EU**. The provider runs inference there, stores any retained data there, and the response identifies the serving region.

## Practical Implication

Use the field for agents handling residency-sensitive code or documents, and check model support through the model list or its regions array. Unsupported pinned requests fail instead of silently leaving the selected region.

## Agent-Ready Context

AI Gateway now accepts **inferenceRegion** to pin supported requests to the **US or EU**. The provider runs inference there, stores any retained data there, and the response identifies the serving region.

Use the field for agents handling residency-sensitive code or documents, and check model support through the model list or its regions array. Unsupported pinned requests fail instead of silently leaving the selected region.

Residency is opt-in: requests without the field route globally. Regional rates are set by providers and are often **about 10% higher**, while model availability varies by region.
