Output unit: the thing actually being sold
An output unit is what is actually being sold: a second of footage, a finished clip, or a credit that converts into one of those. The unit decides how a retirement appears, because a model priced individually leaves a visible gap and a model inside a bundle does not. As of 2026-09-22.
| Unit sold | What a model leaving looks like |
|---|---|
| A second, priced per model | A price disappears from the list |
| A finished clip, priced per model | The same, with a different denominator |
| A credit, converted per model | A table edit, indistinguishable from a repricing |
| A subscription covering several makers | Nothing published changes at all |
Inclusion rule. Distinctions drawn from the priced pages in this register. Two entries meter per model and the rest bundle. Order. From the most legible unit to the least.
1Per-model pricing produces the record for free
Where each model carries its own price, the invoice already says which engine produced what. That is exactly the per-file record this register keeps recommending, and on one entry it arrives as a by-product of billing.
On a bundled subscription the same connection cannot be reconstructed, so the record has to be kept deliberately or not at all.
2Two units on one page is a disclosure
One entry states that some models meter a second and others a whole clip. That is a budgeting fact and a clue about the product: units are delivered rather than accumulated, so no library sits behind them.
Which is why that entry's stored work cell is structurally empty rather than merely unanswered. The shape of the meter explains the shape of the silence.
3A bundle hides the arithmetic in both directions
A subscriber cannot tell what a model costs, and cannot tell what its removal is worth either. So the commercial effect of a retirement is as invisible as the technical one.
Neither is a criticism of bundling, which is what most customers prefer. It is the reason this register reads priced pages rather than feature pages.
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 a bundle read against a line item. Nearby terms: Tier gating, Default engine, Announced date.
