Wan on a boolean that has to be set on every request
The reference describes the control as a boolean with a false default. Like its neighbour reached through a similar interface, the state of any given file was decided by code rather than by an account. As of 2026-09-22.
| Point | What the record holds |
|---|---|
| Who controls it | The caller: a boolean documented as defaulting to false |
| Read from | A text-to-video API reference for the hosted model |
| What it does not settle | How anything running downloaded weights behaves |
Inclusion rule. One cell of this generator's entry, quoted from the page the entry names. Coverage, commentary and third-hand summaries are not admitted, in either direction. Order. Fixed order: the cell, the page it came off, then the limit on reading it.
1Two interfaces, the same lever, different consequences
This entry and one other in the record both document an optional flag defaulting to off. As descriptions of an interface they are the same design. As facts about the world they are not, because only one of these models also ships its weights.
A flag reaches whoever calls the hosted interface. It does not reach an operator running the weights on their own hardware, and that operator is generating video with no boolean in sight.
2A boolean is the cheapest possible control and the easiest to lose
Setting one field is less work than any other lever in this record. Nothing has to be bought, no setting has to be found, and the decision can be made per clip if a production wants it made per clip.
The cost is that nothing remembers. There is no page to revisit and no invoice to consult, so a question about a file from last quarter resolves to whatever the pipeline wrote in its own logs.
3What the lever produces when it is used
The same reference states what the flag puts on screen and where, which makes this the only per-call lever in the record whose result is described rather than merely named. Those properties are recorded on their own rows.
Read together, the entry says a specific notice is available on demand and absent by default. Neither half of that sentence is a position on the article, and the record does not supply one.
