After effectively cancelling the consumer release of its o3 reasoning model, OpenAI now says that it plans to release both o3 and a next-generation successor, o4-mini, in “a couple of weeks.”
In a post on X on Friday, OpenAI CEO Sam Altman said the change in roadmap is related to OpenAI’s upcoming GPT-5, which OpenAI has previously said will be a unified model that incorporates so-called reasoning capabilities.
“[W]e are going to be able to make GPT-5 much better than we originally thought,” Altman said. “[W]e also found it harder than we thought it was going to be to smoothly integrate everything. [A]nd we want to make sure we have enough capacity to support what we expect to be unprecedented demand.”
Altman added that OpenAI expects to release GPT-5 “in a few months” — later than originally planned.
