OpenAI Sora, read against Article 50
OpenAI Sora is documented in a system card rather than on a plan table, and it lists three provenance measures side by side: signed metadata on every asset, a visible moving watermark on downloads, and detection tools the vendor keeps in-house. As of 2026-09-12.
Fig. 1 The list is short enough to set against the article clause by clause, which is unusual for material written about a product.Fig. 2 Filled where the page behind the row names something in that column, hollow where that page is silent. Silence is recorded rather than filled in.
What OpenAI Sora publishes, set against the two duties Article 50 imposes. Recorded 2026-09-12.

Inclusion rule. Points are the same four for every generator recorded here: the two Article 50 duties, who controls the mark, and whatever the vendor states about it. A point the vendor does not publish is recorded as not documented. Order. Fixed order, identical on every generator page.

2Three measures listed together, which nothing else here does
The section this entry comes from is headed provenance and transparency, and it gives a bulleted list rather than a sentence buried in a feature table. That format matters for a record organised by clause, because a list of three named measures can be set against the two duties in the article without any reading-between-lines at all.
C2PA metadata on all assets, providing verifiable origin through an industry standard
That bullet is the shortest statement in this record that lands squarely on the provider duty: a named industry standard, applied to everything, described as carrying origin rather than as decorating a file. The paragraph asks for output marked in a machine-readable format, and a signed manifest is what the phrase points at.
The third bullet on the same list describes tools for assessing whether a video or audio clip came from the vendor, and describes them as internal. That is honest documentation and it is also a boundary: an obligation that a viewer or a platform can act on needs something readable by somebody other than the party who wrote it.
Set against the four qualities the marking paragraph names, the metadata bullet reaches the interoperability one through the standard it names, and this bullet does not reach it at all. Recording both on the same page is the point: one measure is published as an industry format and the neighbouring one as a house capability, and only the first is inspectable from outside.
Four words is all a row holds. Where a cell read off OpenAI Sora's Sora 2 system card needs the sentence behind it, the kind of document that sentence sits in and the limit on what it proves, it is filed on its own page below.
Sora on signed metadata — The Sora 2 system card names C2PA metadata on all assets as its first provenance measure.
Sora on a moving watermark — The system card describes a visible moving watermark on videos downloaded from the site or the app.
Sora on tools kept in-house — The system card's third provenance bullet names tools for assessing whether a clip came from the vendor's products, and calls them internal.
Sora on the download route — The visible watermark is described on videos downloaded from the site or the app, which scopes it to a route rather than to an account.
