AI Partnership Put to Rest

Microsoft and OpenAI have put to rest any doubts about their partnership, with OpenAI's GPT 5.6 becoming the preferred model powering Microsoft's 365 Copilot.

Earlier this week, Bloomberg reported that Microsoft was replacing some of OpenAI's software with its own in-house models, known as MAI, in an effort to cut costs. These in-house models were increasingly being used to power apps like Word and Excel, the outlet noted.

However, this latest development suggests that OpenAI's software will continue to play a significant role in powering Microsoft's apps.

According to OpenAI, GPT 5.6 will support Microsoft users across the company's suite of productivity apps, including Word, Excel, PowerPoint, and Cowork.

"Our partnership with Microsoft has always been about bringing the benefits of advanced AI to more individuals and organizations, and we’re excited to continue building on that shared commitment," OpenAI wrote in a blog post.

While the exact implications of this partnership are unclear, it's evident that OpenAI's software will continue to be a key component of Microsoft's ecosystem.

• GPT 5.6 will become the preferred model powering Microsoft's 365 Copilot.
• OpenAI's software will continue to support Microsoft users across various productivity apps.
