OpenAI's Text Watermarking Approach Begins With Researcher Access

OpenAI says it is setting out its approach to text watermarking under EU provenance rules. Its own description of the material says it covers where watermarks apply, how detection works, and why access starts with researchers.

That last point is the one worth holding onto. Deciding that detection begins with researchers, rather than being handed out broadly, is a choice about who gets to check a claim of authorship, and the order in which a tool like this gets distributed shapes how much it helps. It is also the company describing its own system, which makes the document a statement of intent as much as a technical disclosure.
