Model ID
A string that uniquely identifies a pretrained model in SageMaker JumpStart, typically composed of the model name, framework, and version. It is used to obtain the model object and to associate the inference image and default hyperparameters.

The author now treats model IDs as leases rather than identities—they have a term, need renewal, and require a reminder before expiry.
In large model APIs, the model ID is usually the string value of the model field in the request body, determining which weights and inference configuration the server routes to.
Production systems generally lock to immutable snapshot model IDs, while test environments use stable aliases to detect changes early.
Rollback capability requires that the old model's call path remain available during the switch, and that model IDs not be hard-coded but instead dynamically delivered via a configuration center.
