OpenAI will release its GPT-4.5 and GPT-5 models within "weeks" and "months," CEO Sam Altman said in posts on X Wednesday.

Yes, but: Altman's "roadmap update" says that the o3 reasoning model, previewed with fanfare in December, won't get its own independent release, as originally planned, but will instead be integrated into GPT-5.

The big picture: OpenAI's next big model releases will be closely watched by the AI industry to see how the company's continued massive investments in scaling up large language models are paying off.

Between the lines: ChatGPT has become a bit of a maze for users, who have to select which of several confusingly named AI models should answer their questions.

What they're saying: Altman wrote, "We want AI to 'just work' for you; we realize how complicated our model and product offerings have gotten. We hate the model picker as much as you do and want to return to magic unified intelligence.

Altman said GPT-4.5, "the model we called Orion internally," will be "our last non-chain-of-thought model."
"In both ChatGPT and our API," he added, "we will release GPT-5 as a system that integrates a lot of our technology, including o3."
