Two stages with figures against three states you can query
These are the only two entries in the register with a real lifecycle vocabulary, and they built it differently. One publishes two stages, and the stage decides how many days of notice a retirement owes. The other publishes three states and exposes the current one through its interface. As of 2026-09-22.
| On this point | Microsoft Foundry | Amazon Bedrock |
|---|---|---|
| How many conditions | Two stages, plus retired | Three states, named on the page |
| Where the current value lives | In the model's documented stage | On the model, readable by software |
| What the condition decides | Thirty or sixty days of notice | Whether new adoption is allowed |
| What ends the last one | Requests return 410 Gone | Removal from all regions |
| Can the condition be checked automatically | Not described | Yes, through the interface |
Inclusion rule. Both cells on a row come from the entry's own lifecycle documentation. A state named for a non-video model still counts, because these policies cover every model served. Order. Number of conditions first, then what each one is wired to.
1One vocabulary is wired to days, the other to software
Stages that set a notice period tell a production what it is owed before anything happens. States exposed through an interface tell software when to start worrying. Those are different kinds of usefulness and neither entry has both.
A production would want the first and a platform team would want the second. Most readers of this register are the first and are two layers away from either.
2Three conditions describe a process; two describe a status
Naming a middle state with a period attached turns a removal into something with a beginning. Two stages plus retirement describe where a model sits rather than how it leaves, and the leaving is covered by the notice policy instead.
Both end up with a period and a date. They arrive at it from opposite directions, which is why the register keeps the state column separate from the notice column.
3Neither is an application
These are the two most complete lifecycle vocabularies here and both belong to platforms selling to developers. Twelve applications publish no state of any kind.
That pattern is the finding rather than the details of either vocabulary. The notice question examines why the commitment appears on one side of the market.
