# Technical question: provider-attested served revision for Inference Providers > Source: > Published: 2026-08-02 08:27:30+00:00 Hello Hugging Face Inference Providers team, We operate a governance evaluation using sanitized, non-sensitive prompts. A provider-pinned routed call to openai/gpt-oss-120b:fireworks-ai completes and reports provider/model/usage, but the response does not expose a value that binds that response to the exact immutable revision or artifact digest served by the underlying provider. Could you confirm whether there is a currently supported non-sensitive response field or header for: If not, is there a supported Inference Providers configuration that provides provider-attested served revision metadata for every call? A Hub commit alone is insufficient for this purpose because a routed provider may serve different weights. We do not need account-specific help and will not include credentials, client content, account identifiers, or request IDs. Thank you.
