I'm sorry but I simply do not believe you that it does handle things like puns and things requiring footnotes, my experience is that LLMs are miserable at this even when directly "instructed" to.

But for what it concerns my previous comment: It doesn't really matter what the "state of the art" AI is because companies simply do not use that. They just pipe it through the easiest & cheapest models, human review (that does not actually get the time to do meaningful review) optional.
