Inference locations

Provider API declarations are also available on each model's endpoint API. Direct chat and Responses replies separate advertised availability from serving location in usage.inference_location; the actual serving region remains unknown when not reported.

usage.provider_usage.gateway_region identifies the TrustedRouter gateway, not the provider's inference location. A value such as europe-west4 does not mean the model ran in Europe. usage.inference_location.serving_region remains null when the provider has not reported it. Older gateways may return the gateway-only field as provider_usage.region.

Where the upstream GPUs execute the model, not the provider's headquarters, API ingress, or data storage. ZDR and confidential inference do not by themselves restrict geography.

Declared countries or regions

Not verified
TrustedRouter uses api.siliconflow.com. Neither its hostname nor the provider's Singapore legal jurisdiction establishes the DeepSeek V4.1 Flash GPU location. No exhaustive route-specific country list verified.

Can locations change?

Per-model placement and cross-country failover behavior are unconfirmed.

Provider region pinning

No verified per-request regional pin for the integrated shared endpoint.

Pinning through TrustedRouter

Not supported by the current TrustedRouter integration.

Infrastructure declaration

Inference countries unconfirmed; no verified country-specific residency commitment.

Evidence

Public API and privacy documentation reviewed; GPU geography unconfirmed. Reviewed 2026-09-26.

• API documentation
• Privacy policy (not a GPU-location declaration)

Provider selection alone is not a region pin. TrustedRouter's US provider filter selects company jurisdiction, not GPU location. A regional gateway hostname does not pin a downstream GPU. For a binding residency requirement, confirm the model, region, failover scope and enforced controls before sending sensitive data.
