“GPT-5 will appear smarter beginning at present. Yesterday, we had a sev and the autoswitcher was out of fee for a bit of the day, and the consequence was GPT-5 appeared manner dumber. Additionally, we’re making some interventions to how the choice boundary works that ought to assist you get the best mannequin extra typically. We’ll make it extra clear about which mannequin is answering a given question,” Altman promised.
Nonetheless, folks on the AMA lobbied so onerous to carry 4o again for Plus subscribers that Altman promised to a minimum of look into that. “We’re wanting into letting Plus customers to proceed to make use of 4o. We are attempting to assemble extra information on the tradeoffs,” he wrote.

In any case, Altman promised fixes to the objects that appeared to concern folks essentially the most. He ended the AMA with a promise: “We’ll proceed to work to get issues secure and can maintain listening to suggestions.”
