OpenAI announces GPT-5

OpenAI announced that GPT-5.6 will become the preferred model of Microsoft Copilot 365, responding to rumors that the cooperation between the two parties has broken down. As discussions about the partnership between technology giants continue to heat up recently, OpenAI officially announced on Thursday that its latest GPT-5.6 model will become the "preferred model" of Microsoft Copilot 365. The move is widely seen as OpenAI's latest attempt to dispel speculation about the breakdown of its partnership with Microsoft. Previously, Bloomberg reported earlier this week that in order to cut costs, Microsoft is trying to gradually replace some of the OpenAI software with a self-developed model called "MAI". According to reports, these internally developed models have been increasingly used in core productivity tools such as Word and Excel. The news triggered widespread market speculation about whether the two technology giants, which have long worked closely together, are "parting ways." In a blog post published simultaneously on Thursday, OpenAI made it clear that GPT-5.6 will provide support for users in the Microsoft productivity suite, covering applications including Word, Excel, PowerPoint and Cowork. OpenAI reaffirmed the two parties’ commitment to cooperation in the statement, saying that its cooperation with Microsoft has always been aimed at bringing the benefits of advanced artificial intelligence to more individuals and organizations, and it looks forward to continuing to build on this shared vision. Although OpenAI carries the title of "preferred model," the specific meaning of this term is not yet fully clear, and it can only be confirmed that OpenAI's technology will continue to be an important power source for Microsoft applications. Some analysts pointed out that this latest official statement does not seem to directly overturn previous reports that Microsoft is increasing its reliance on its own software in order to reduce costs. Even in the context of "preferred", Microsoft's exploration of diversified model architectures in actual operations may continue.
