no, and that is widely known. the actual problem is that the margins are not sufficient at that scale to make up for the gargantuan training costs to train their SOTA model.
i.e They made more money on 3.5 than 3.5 cost to train, but didn't make enough money on 3.5 to train 4.0.
Because inference revenue is outpacing training cost based on OpenAI’s report and intuition.
