Regional inference now available on AI Gateway
Why it matters
Vercel removes friction for enterprises with data residency requirements by standardizing regional inference across all model providers on AI Gateway, making compliance-first deployments easier to audit and enforce.

- Residency is opt-in; requests without inferenceRegion flag route globally
- Supports all model providers that serve selected region with consistent behavior
- Request fails rather than failover if no provider available in pinned region
- AI Gateway now supports pinned regional inference (US, EU, global)
- Single inferenceRegion field replaces per-provider configuration
- Regional routing costs ~10% premium over standard rates
- Response includes region confirmation for audit/compliance verification
- Requests fail rather than falling back to non-compliant regions if provider unavailable
- Feature targets enterprises with data residency and compliance requirements
