> What does it mean "no AI"?
It means no AI. If I say you used no AI but had an LLM write or refine the script, I would have lied.
You may be getting downvoted because your comment's tone can read as accusatively presumptive. "Who knows" isn't a useful contribution to almost any discussion. Which is a shame, because you raise an interesting point–I would personally feel fine saying no AI was used to do work even if I used AI to help me with research. (Provided I read all the primary sources.)
I think he's right. We have no idea if AI contributed to the ad in any way, so "no AI" in this context only means "not AI-rendered". The entire script might have been written by an LLM (which is perfectly fine by me).
On the other hand, the McDonald's ad is obviously AI-rendered, but all the concepts and prompts and choices might have been made by humans? Which doesn't make it any better (although it's not that bad, it's just average).
