China announces plan to label all AI-generated content with watermarks and metadata.

This is a most excellent place for technology news and articles.
How so? If it's anything like llm text based "water marks" the watermark is an integral part of the output. For an llm it's about downrating certain words in the output, I'm guessing for photos you could do the same with certain colors, so if this variation of teal shows up more than this variation then it's made by ai.
I guess the difference with images is that since you're not doing the "guess the next word" aspect and feeding the output from the previous step into the next one, you can't generate the red green list from the previous output.
