I was extremely skeptical, but after playing with these things and listening to discussions held by their creators, I'm fairly convinced that this is intelligence-adjacent. In the same sense that there must be thoughts an organic brain can't think, there are types of intelligence that don't map exactly onto ours. Vaguely like Feynman's peculiary methods of doing integrals - his method was different, so he could solve things unsolvable by people with standard methods.
after this LLM breakthrough a lot of smart people started questioning what intelligence really is.
