The issue here is that the artists are confident that the suggestions (which they don't themselves understand) are good because they came from ChatGPT.
I would argue that if you cannot answer questions on something generated before suggesting it or handing it off, you absolutely should not be pushing for it. Do the research necessary to feel fully confident on a hand-off.
Hell, if something doesn't make sense, ask it again for clarity. It does a reasonable job at that, but again, before you hand off a solution, make darn sure you understand it, because chances are high, whoever pitches a solution that sounds usable, is going to break ground and work it.
Honestly had the same experience with a junior developer yolo-ing some changes into a PR before even running it themselves to check that it works. It's just a waste of everyone's time and a lack of respect. That's what needs to be conveyed to the artist colleagues.
