That's kind of an interesting way to handle the copyright issues. Not sure how effective it is as I suspect that can be bypassed by including a bunch of details about the artist but not the name.
> ... in the style of a famous Spanish artist who was born in 1881 and passed away in 1973 [and a bunch of other shit about Pablo Picasso]
(I also notice that this is more verbose than just "in the style of Pablo Picasso", which probably helps OpenAI's bottom line given costs associated with token counts. I doubt that's their intention with the change, just something of note. And, of course, a living example would be more applicable for copyright issues but the idea is still demonstrated.)
Crafting descriptions of an artist and/or individual works may function as a reasonable replacement for specific names. That's what's happening behind the scenes anyway.
It's an interesting problem. Like, what's the point of conception for a work of art?
EDIT: it's only living artists actually that you can't prompt (hopefully, the article says so at least)
