What is the role of a model registry in CPMAI governance?

• A. A repository for storing user feedback on models.
• B. A documentation hub for marketing AI capabilities.
• C. A repository documenting models, versions, lineage, and retirement criteria.
• D. A service to host model endpoints.

Answer: (C)

A model registry in CPMAI governance acts as a centralized ledger that records each model, its versions, lineage, and retirement criteria. This enables clear traceability and reproducibility across the model lifecycle: you can see which version was used for a decision, how that model was derived, and when it’s appropriate to retire or replace it. It also supports governance and compliance by providing metadata for audits, access control, and policy enforcement, helping ensure models meet organizational and regulatory standards. This focus on documentation of what exists, how it evolved, and when it should be retired distinguishes it from repositories for user feedback, marketing documentation, or hosting model endpoints.
