In recent days, rumors of a potential rift between OpenAI and Microsoft have stirred the tech industry. Bloomberg reported that Microsoft was replacing some of OpenAI's software with its own internal models, known as MAI, to cut costs, fueling speculation of a breakup. However, on Thursday, OpenAI launched the GPT-5.6 family of models and announced that it would become the preferred model for Microsoft 365 Copilot, a clear move to reaffirm the strength of the partnership.
OpenAI Dismisses Breakup Rumors with Microsoft
The Bloomberg report raised questions about the future of the collaboration between OpenAI and Microsoft, once considered inseparable. Microsoft's internal MAI models were being used in apps like Word and Excel to optimize costs. But during the GPT-5.6 launch event, OpenAI aimed to dispel any doubts. In a blog post, the company stated: "Our partnership with Microsoft has always been about bringing the benefits of advanced AI to more individuals and organizations. We are excited to continue building on that shared commitment." GPT-5.6 will support Microsoft users across the entire productivity suite, including Word, Excel, PowerPoint, and Cowork.

GPT-5.6 Becomes the Preferred Model for 365 Copilot
The term "preferred model" may sound ambiguous, but in practice it means that OpenAI's software will continue to power Microsoft's productivity applications. Despite the speculation, it was never reported that ChatGPT would stop powering Microsoft's apps. Instead, Microsoft was increasingly relying on its own models to reduce costs. The new disclosure does not negate that previous report but reinforces the centrality of the partnership. GPT-5.6, with its Sol, Terra, and Luna variants, represents a significant leap in efficiency and cybersecurity. Integration with Microsoft Copilot 365 will offer users advanced productivity tools, automating complex workflows.
