They say this is their last fully non-reasoning model, but that research on both types will continue.
No, they said that GPT4.5 and GPT5 will be their last non-reasoning models.
They say it’s currently limited to Pro users,
Meh, it’s coming to plus users in ~a week.
It claims to be more accurate at standard questions and with a lower hallucination rate than any previous OAI model (and presumably any others).
I think this is a big point and a better world knowledge is going to prove tremendously useful when it comes to applying RL to base models and a lower hallucination rate leads to effective exploration of the reasoning space + a better dataset after rejection sampling. Which should lead to lots of gains over models trained with RL over 4o.
Not to speak about alignment—but looks like a big W for OpenAI—especially if they’re going to raise in the near future (<6 months).
