How to Confirm a Production Service Loaded the Intended Model Artifact

A model deployment may appear complete while long-running workers continue using a previous artifact or a cache points to the wrong version. This can make evaluation results differ from production behavior and complicate rollback.

Trace artifact identity

Record the artifact checksum or immutable ID, model version, deployment timestamp, and worker instance. Check startup logs and any artifact download cache. Confirm that every replica reports the expected model and feature schema.

• Use immutable artifact identifiers rather than mutable filenames.
• Expose model version in internal health or inference metadata.
• Drain old workers and verify rollout completion.
• Test a representative request after deployment.
