“O-one like, to be perfectly honest, it was really mostly good at solving puzzles and like maybe a few kind of thinking problems here and there, but it wasn't like, it wasn't a very useful model. It was almost more like a technology demonstration.”

Tworek: GPT-5 can effectively be considered an iteration like 'o3.1'
“Like GPT-Five in some way I can be considered as like, oh, 3.1. It's a little bit of like, you know, iteration of like the same thing and the same concept”
Tworek: OpenAI team was initially underwhelmed by pre-trained GPT-4
“When we trained GPT-IV, we were pretty underwhelmed internally, and then there was a lot of moments, oh, we trained this small, we spent a lot of money on it, and it's kind of like, you know, pretty dumb, at least, like, you know, we have GPT-IV, GPT-III alrea…”
Tworek: Traditional human data labeling is becoming obsolete as models advance
“I think, like, in a way, I think it's getting more and more to be a thing of the past as the models are getting smarter and smarter. This is becoming less of a thing, but I think a few years back, and especially in GPT-IV days, this was the thing.”
Tworek: Calling LLMs strictly next-token predictors is inaccurate in RL era
“Language models do on their own, like fundamental level is they are often called as next token prediction machines. And that's not completely accurate in the age of reinforcement learning, but they still operate on mostly on tokens that are mostly text.”
