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 console always stamps videos; the API takes a watermark parameter that defaults to off. As of 2026-09-22.

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.

1Two surfaces for the same model, with opposite defaults

Videos generated on the Online Experience page of the console always carry a watermark, described as the text AI generated in the lower-right corner, and the guide states it cannot be turned off from the console UI, attributing that to legal compliance requirements. The same models called through the API behave the other way: the request takes a boolean watermark parameter, documented as adding a watermark in the lower-right corner with the text AI Generated, and its default value is false.

So the mark here is not bought or switched in a settings screen. It is decided by which door the caller came through, and for API callers by a field in the request body. A studio evaluating the model in the console and then shipping through the API would see the mark disappear without changing any plan, which is a transition nothing else in this register produces.

2Why the default is worth recording as carefully as the parameter

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.

The compliance sentence attached to the console lock is the only place in this register where a vendor explains an unremovable mark by pointing at a legal requirement. It is recorded as the vendor's own stated reason and nothing further, because this register does not assess whether any product meets any rule. No provenance standard or metadata field appears in the API reference, so the machine-readable field is 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.
