I find the chatgpt-4o advanced mode to absolutely be "really interesting". And the video input they showed in the demos (and hope would same day release) could be a real game changer. One thing I would like to try, once that's out, is to put a computer with it amongst a group of students listening to a short lecture about something outside its training set and then check how the AI does on a comprehension quiz following the lecture - my feeling is that it would do significantly better than the average human student on most subjects.
