Before GPT-5 was launched, and after sama had said they would unify the ordinary and reasoning models, I think we all expected more than an (auto-)switcher, we expected some small innovation (smaller than the ordinary-to-reasoning one, but still a significant one) that would make both kinds of replies be in a way generated by a single model (don't know exactly how, I expected OpenAI to surprise us with something that would feel obvious in retrospect).
