Model registry.
A model registry is the catalogue of trained models: versions, the data and code that produced each, evaluation results, stage — staging, production, archived — and who approved the promotion.
Where Model registry fits on a long engagement.
The question a registry answers is the one that matters after an incident: which model is in production, what produced it, and how did it score. Without one, the answer is reconstructed from memory and file names, and it is frequently wrong.
Promotion should be a governed transition rather than a file copy. A model moving to production ought to carry its evaluation results, an approver and a timestamp, because that record is what makes a rollback decision possible when a deployed model starts behaving differently.
What an assigned team does with Model registry.
Lineage is the part that is hardest to retrofit. Linking a model version to the exact training data, code commit and hyperparameters has to be captured at training time; afterwards it is genuinely unrecoverable.
Building that in from the first training run is far cheaper than adding it later, and it is part of the delivery standard scoped under ai engineering services.
What we use Model registry for.
- Knowing what is actually deployed A definitive record of the production model and what produced it.
- Rollback to a known-good version Previous models retained with their scores, so reverting is a decision rather than a rebuild.
- Promotion with an approver A governed transition carrying evaluation results and accountability.
How Model registry capacity is assigned.
Model governance is assigned inside AI capacity, with lineage captured at training time because it cannot be reconstructed afterwards.
