OpenAI's GPT-5.6 Becomes Preferred Model for Microsoft 365 Copilot

• •OpenAI's GPT-5.6 is now the preferred model for Microsoft 365 Copilot.
• •The integration aims to improve productivity across Microsoft applications.
• •Microsoft is reportedly developing its own in-house models, raising questions about the partnership.

OpenAI has announced that its GPT-5.6 model will be the preferred engine for Microsoft 365 Copilot, integrating into applications like Word, Excel, and PowerPoint. This update aims to enhance productivity by providing better reasoning and precision while using fewer tokens than previous versions. Despite this announcement, there are reports that Microsoft is increasingly relying on its in-house models, known as MAI, to reduce costs. OpenAI emphasized its commitment to the partnership with Microsoft, stating that the integration of GPT-5.6 will help users create and collaborate more effectively. However, the exact implications of being the 'preferred model' remain unclear, as it does not negate prior reports of Microsoft shifting towards its own software solutions. The integration is expected to benefit millions of Microsoft 365 users globally.
