How AI text watermarking works: a visual guide

I’m not convinced that they even know 100% how Anthropic is doing it. I can think of an easier way that doesn’t corrupt the text: just find a bunch of tokens where there is a good spread of token possibilities, and the more often the most likely one is chosen, the more likely it’s AI.

That being said, it doesn’t seem much different from what any of us do to identify AI text — it has lots of tells anyway.
