Preview model: shorter notice, and no promises
A preview model is offered before general availability, usually with an explicit reservation that things may change. Where a platform ties its notice period to the stage, preview carries the shorter figure, and in this register the hosted video model is at preview stage. As of 2026-09-22.
| The label signals | What follows for a production |
|---|---|
| Behaviour may change without notice | A season cannot be guaranteed to look the same |
| The model may never reach general availability | Building a long run on it is a decision |
| A shorter notice period, where one exists | Thirty days rather than sixty |
| An earlier retirement date, in one case here | Preview identifiers went first |
Inclusion rule. Read from the lifecycle documentation and deprecations pages in this register that distinguish a preview stage. Order. What the label signals first, then the consequences.
1The label is a warning that most teams accept anyway
Preview models are often the newest and most capable, so productions use them knowing the reservation exists. The practical rule most teams settle on is that preview is fine for exploration and for anything with a short life.
A run of episodes that has to look the same in twelve months is the case where the label matters, and it is exactly the case where the newest model is most tempting.
2Preview lines have already gone first, once
In the one family here with dated rows for both stages, the preview identifiers carried the earlier shutdown date. So a team that built during a preview period was on the shorter runway with nothing on the page grouping the two as one decision.
That is a single observation rather than a rule. It is consistent with the stage-based notice policy published elsewhere in this register, which points the same way.
3Naming the stage is itself a disclosure
Two platforms in this register distinguish a preview stage. Twelve applications publish no stage at all, so a customer cannot tell whether the engine behind a tier is a released model or an early one.
A production that would decline a preview model cannot decline what it cannot see. The lifecycle states column records which entries publish a stage.
A definition rather than a dated entry: no line above is a vendor statement. Where this word turns up in a real notice, the wording and the date are on the preview lines already switched off. Nearby terms: Non-extendable date, Model version, Version alias.
