It’s the same problem with those ML models, the other day someone generated a children’s book using GPT3, turned out that there is a real children's book with the same name and a very similar content: The Very Lonely Firefly by Eric Carle.
Does anyone even know? Can we even check? What if 1 in a thousand, or one in a million outputs is (very close to) something existing? I find this especially relevant when generating faces.
