February 21, according to foreign media The Verge today, according to people familiar with the company's plans toMicrosoft engineers are currently working on the OpenAI upcoming GPT-4.5 and GPT-5 model preparation server capacity.
While OpenAI CEO Sam Altman recently acknowledged that GPT-4.5 will be available in a few weeks, the report mentions that Microsoft expects toNext week at the earliest.will be able to host this new AI model.
GPT-4.5 is OpenAI's next frontier model, code-named Orion, and its final non-thinking chain model. openAI has hinted that GPT-4.5 may be much more powerful than GPT-4, and the subsequent GPT-5 model is expected to see even more significant changes.
The report also states thatMicrosoft expects GPT-5 to be released at the end of MayThis is consistent with Altman's promise that the next generation of models will arrive in a few months.
While OpenAI released o3-mini last month, OpenAI no longer plans to release the o3 inference model separately.Instead, it is integrated into GPT-5. This is in line with OpenAI's goal of combining its large-scale language models to eventually create a more powerful model that can be labeled Generalized Artificial Intelligence, or AGI.
This update to GPT-5 will unify OpenAI's o-series and GPT-series models to achieve functional unification.
1AI notes that if OpenAI manages to launch GPT-5 by the end of May, it will coincide nicely with Microsoft's Build 2025 developer conference -- the The conference will begin on May 19th.
