How AI text watermarking works: a visual guide

But it doesn’t work. It looks like only the owner of the text generator is able to check if some text is written with this concrete generator (with some probability). I see no use of this technique.

It works for them not scraping their own slop back into training data. I assume that is actually the real purpose of the system. They don’t want to share the key with the public. But they probably will with other llm companies in exchange for theirs.

Hmm, yes. I just thought about outside usage, somehow haven’t thought about it as an inner LLM maintenance tool.

The article seemed to claim that some models allow outsiders to submit text for detection if I read it right. That seems like a decent way of doing it. If you “open source” the raw data, it means people can do things to try and get around it - same reason most websites don’t reveal their anti-spam techniques.
