All ml is AI, based on the use of the term AI for many decades. For many problems I think it’s more descriptive (learning the rules from data rather than being shown them) and not all classical AI is ML (path finding for example). LLMs are absolutely ML and AI as far as tradition goes and personally I think are one of the very few things that are AI as regular people might have thought it meant back when it was much more obscure (I was into it before it was cool dontchaknow, an AI hipster).
