This is really fascinating. Even the AI companies have incentives to reject AI generated content. It's like they want you to use AI for everything, but they don't want AI output fed back to them.

At work, right after an AI training, we were asked to use our "authentic" voice when writing mid year reviews.

Claude watermarks are a farce and a waste of time. It's hilarious to me that they burn cash to even entertain the idea. Any attempts they use are defeated by a text editor and CTRL SHIFT V. Unicode characters are no new thing. Reminds me of how people tried to argue that NFTs aren't anything more than just jpegs.

You misunderstand how Claude watermarks things.

TFA is talking about C2PA, a regular signature in the meta data. A lack thereof means nothing, but if it's there, the false positive rate should be near zero.

Earlier quoted context omitted.

Yes, but I also think it will be trivially by-passable if you pass your output through another LLM. At least for text. It might help catch students cheating, but not real spam-bot usage. As soon as platforms start checking for watermarks spambots will add anti-watermark passes.

I read through their earlier announcement, i don’t think it’ll be trivially by-passable without distorting the original message.

I would agree it may not help spam-bot usage, however at this case seemingly the only user detection is likely an id/badge check, which is not good.

How long before they change the terms and conditions to subtly claim ownership of your files? When you write code they already insert Co author attribution/ Say I write a text by hand And then I tell it to clean up the grammar and fix some sentences Did it make it? This is also interesting for those companies that siphoned the entire open web

Microsoft Word has not claimed ownership in 40 years. Why would Anthropic do?

Just like the tech company owners not allowing their kids access to social media…

Could this be used to perform some sort of distillation or exploit? e.g. reminds me of the OWASP guideline on attack vectors where knowing if an ID is present or not in the database can be a form of exploit, like in password resets where they will say 'email foo@bar.com not found' rather than 'If foo@bar exists we have sent an email to foo@bar' or some other generic equivalent
