Model lines with exactly one place to buy them
Eight model lines in this register appear on exactly one entry's pages, and in every case that entry is the company that made them. One page describes each line, one schedule governs it, and there is no second menu on which a change would show up. As of 2026-09-22.
| Model line | The single entry carrying it | What that concentrates |
|---|---|---|
| Aleph 2.0 and Gen-4.5 | Runway | One credit table, and no resale surface |
| Firefly Video Model | Adobe Firefly | Spans the tiers, so every plan depends on it |
| LTX-2.5 and LTX-2.3 | LTX Studio | Two generations, both under one clause |
| Pika 2.5 | Pika | Every plan, and nothing listed behind it |
| PixVerse V6 | PixVerse | Promoted, with earlier versions unmentioned |
| Ray3.2 and Ray3.14 | Luma | Two house lines on a mixed plan table |
| Vidu Q3 and Vidu S | Vidu | A speed split rather than a version cushion |
Inclusion rule. A line appears when exactly one entry in this register names it publicly. Lines carried by two or more entries are on their own pages instead. Order. Alphabetical by model line.
1One carrier means one document
For a widely carried line, several pages describe it and a reader can cross-check. For these lines there is one page, written by the company with a commercial interest in how it reads, and no second source.
That is not a criticism of any entry. It is the structural consequence of a house model, and it means the register's usual method of comparing two readings has only one page to compare across time.
2Concentration cuts both ways
A single carrier controls the schedule, which removes the inherited dates every aggregating entry carries. It also removes the fallback: when a house line moves, there is no other product still selling the old version.
Two of the lines here sit in pairs, an older and a newer generation on the same page, which is the nearest thing to a cushion on this list. Nothing states how long either pair lasts.
3Where this leaves the reader
For these lines the only evidence of change is the entry's own page, read twice. The register records what each page says today and the date it was read, which is the whole of what can be verified.
The counterpart page, lines on more than one menu, counts the opposite case. The two together are the carriage axis of this register.
4Sources
Each row is read from the page that entry publishes itself, 2026-09-22, and any date comes from whoever makes the model. Every announced date is on the calendar. Other models read this way: Lines on several menus, Veo 3.1.
