Probably in between. The point of my comment is that depending on how you interpret the description "predicts the next token", something that can do this well enough should be superhumanly clever. The task is "AI Complete". Don't misinterpret me as saying that GPT is superhumanly clever. I'm just saying that something that's sufficiently good at what people think GPT is doing, should be superhuman.
