I think there are two separate requirements? One that if you post something like an AI video on the internet or anywhere else, you must label it as AI. And another one that AI providers must watermark their outputs.
If you get caught uploading watermarked media without the clear label, you're in big trouble, mister.
And it mandates that Anthropic put it in their TOS rather than make it law.
We were talking about text.
Which must also be marked as AI, I hope. (But I doubt that is the law, because the EU is cucked to big businesses interests)
