AI Glossary Term
What does “Model Registry” mean?
Definition
A central catalog for versioning, approving, and tracking models across environments.
How Model Registry works
Example
A team keeps every trained model with its data version, scores, and approval status in a registry. If version 7 misbehaves in production, they roll back to version 6 in minutes.
Why it matters
A registry gives traceability and control over which model is live. It helps audits and safe rollbacks.
Common questions
What does it store?
Model files, version numbers, metrics, lineage, and approval stages.
Do I need one?
For a single hobby model, no. For teams running several, it prevents confusion.
Does it connect to deployment?
Often yes, so approved versions can be deployed automatically.
