Models

The registry: a named version line across runs, and which version is in production.

A run id is a fact about an experiment. A model version is a decision — this is the one we are willing to serve. This screen holds the second kind.

The model registry: version lines, promotion and acceptance cards.

What you see

Region	What it shows
Version line	Every registered version of one model, newest first
In production	Which version is promoted, or that none is
Acceptance card	What the version shipped on, frozen at the moment it shipped
Data flywheel	Where the version’s data came from, what evaluated it, and what it is serving

The acceptance card

A card is either clean or it names what is missing. It records the evidence a version shipped on — the evaluation verdict, the data sources, the run that produced it — at the moment of shipping, not as a query run later.

That distinction is the point. Six months on, the run may have been reclaimed and the benchmark suite may have moved, and a question like “what did we actually check before shipping v3” has no answer unless somebody froze it.

A card marked with missing items is not a failure. It is an accurate statement that a version shipped without some piece of evidence — which is worth knowing precisely because it is easy to do by accident.

The data flywheel

Stage	What it answers
Data sources	Which platform datasets the run referenced. “No platform dataset” is itself informative
Training	The run, or that the version was registered from outside with no training run
Evaluation verdict	What scored it, or that nothing has
Serving	Whether it is deployed, and what traffic it takes
Cost	Kept separate on purpose — whether search cost belongs to this version is a judgement, not an arithmetic fact

A closed flywheel means production traffic can feed the next version through Reflow.

What you can do

• Promote a version to production. Deployments pointing at the model follow it.
• Open the acceptance card — it renders as a file a reviewer can read.
• Archive a version, taking it out of circulation without deleting its history.
