How Wan marks its output

Wan on Alibaba Cloud Model Studio (alibabacloud.com) is the one entry whose control is neither a plan nor a setting. The API takes a watermark parameter that defaults to off, and the pages read say nothing about a console stamp or about what the file carries. From 2 source pages, read 2026-10-25; no maker pays to be listed.

Inclusion rule. Fields are the same four for every generator on this site; a field the vendor does not publish is recorded as not documented rather than inferred from how the product behaves. Order. Fixed field order, identical on every generator page.

1A request field, off unless a caller asks

The text-to-video reference lists a boolean watermark parameter and documents it as adding a watermark in the lower-right corner with the text AI Generated, with a default of false. So the mark here is not bought or switched in a settings screen. For API callers it is decided by a field in the request body, which in most organisations means by whoever last edited the call.

A documented parameter whose default is false means the marked output is the exception rather than the rule on the API surface. That is the reverse of the plan-gated rows, where the default state of a file is marked until money changes it. Neither arrangement is stronger than the other, but they put the decision in different hands: a plan is chosen by whoever pays, a request field by whoever writes the integration.

2What the guide no longer says

An earlier reading of the video generation guide, made on 2026-09-22, recorded two statements about the console: that videos made on its Online Experience page always carry the stamp, and that it cannot be turned off there. That guide has since been replaced by a general overview of video generation and editing, and neither statement appears on it, so the register no longer carries them and records the console cells as not documented.

Nothing else in the reading changed. No provenance standard or metadata field appears in the API reference, so the machine-readable field is still recorded as not documented.

3The same field, across every generator

Inclusion rule. Generators whose public pages state whether output carries a mark. A generator silent on this particular field keeps its row, marked hollow. Order. Alphabetical by generator name.
