After effectively canceling the consumer launch of its o3 reasoning model in February, OpenAI now says it aims to release both o3 and a next-gen successor, o4-mini, in “a couple of weeks.” In a post on X on Friday, OpenAI CEO Sam Altman said the reversal in course is related to OpenAI’s upcoming GPT-5, which OpenAI has previously said will be a unified model incorporating so-called reasoning capabilities. “[W]e are going to be able to make GPT-5 much better than we originally thought,” Altman wrote. “[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 roll out GPT-5 “in a few months” — later than originally anticipated. To the extent that OpenAI has published details about GPT-5, the company has said it intends to offer unlimited chat access to GPT-5 at the “standard intelligence setting” subject to “abuse thresholds.” ChatGPT Plus customers will be able to run GPT-5 at a “higher level of intelligence,” while subscribers to OpenAI’s ChatGPT Pro plan will be able to run GPT-5 at an “even higher level of intelligence.”
