Model Registry
A centralized repository that stores, versions, and tracks deployed model artifacts and their associated metadata.
A model registry is the central record of which models exist, what version they are, where they’re deployed, and what performance characteristics they have. Think of it like a package manager for models: instead of models living in ad hoc locations with inconsistent metadata, a registry provides a single source of truth for model provenance and deployment status. This becomes important at scale, when an organization might have dozens of model versions across different products and deployment environments. For behavior architects, the model registry is where behavioral metadata should live alongside technical metadata — notes on what behavioral problems a version fixes, what regressions it introduces, and what evaluation results it produced — so teams can make informed rollout decisions.
