Sam Atlaman announces 'change of plans', says GPT-5 is coming in...

OpenAI has revised its plans and now intends to release both its o3 reasoning model and a next-generation successor, o4-mini , “in a couple of weeks.” This follows the company's previous decision to effectively cancel the consumer launch of o3 in February. Company CEO Sam Altman aslo said that the company’s next AI model, GPT-5 , will come “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,” Altman announced on X (formerly Twitter).

Altman explained that this change of course is linked to OpenAI's development of GPT-5, which the company has described as a unified model with enhanced reasoning capabilities.

“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 though. We also found it harder than we thought it was going to be to smoothly integrate everything. And we want to make sure we have enough capacity to support what we expect to be unprecedented demand,” he added.

“We were able to really improve on what we previewed for o3 in many ways; i think people will be happy,” he added.

What OpenAI said about GPT-5
Regarding GPT-5, OpenAI has previously stated its intention to offer unlimited chat access at the “standard intelligence setting,” subject to “abuse thresholds.” ChatGPT Plus subscribers will have access to GPT-5 at a "higher level of intelligence," while ChatGPT Pro subscribers will be able to utilise GPT-5 at an "even higher level of intelligence."

“[GPT-5] will incorporate voice, Canvas, search, deep research, and more. [A] top goal for us is to unify [our] models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks,” Altman stated in an earlier X post.

Google recently launched the Gemini 2.5 series of models and company CEO Sundar Pichai announced that Gemini 2.5 Pro is now available for users into public preview in AI Studio with higher rate limits..
