Openai his plans has changed and finally yes will launch O3 and O4-miniafter announcing their cancellation in mid -February to bet on the unification of the two main families of models.
The reasoning models, distributed under the family or, will be expanded with O3 and O4-mini, which OpenAi will launch “Probably in a couple of weeks“, As confirmed by the executive director, Sam Altman.
Initially, Altman himself announced in February that O3 would not be launched as an independent model, but part of its technology would be integrated into GPT-5. The reason is that integration was going to be more difficult than they had initially thought.
“We will be able to make GPT-5 Be much better than we originally thought“Altman said in a shared statement in X (former Twitter), which has also said that he will arrive” in a few months. ”
change of plans: we are going to release o3 and o4-mini after all, probably in a couple of weeks, and then do GPT-5 in a few months.
there are a bunch of reasons for this, but the most exciting one is that we are going to be able to make GPT-5 much better than we originally…
