Microsoft 365 Copilot\u003C\u002Fh2>\u003Cp>Microsoft 365 Copilot is the product where this change matters most. It sits inside the company’s productivity suite, so model choices affect everyday tasks such as writing, summarizing, searching, and drafting across Word, Excel, Outlook, and Teams.\u003C\u002Fp>\u003Cp>For customers, model selection is usually invisible, but it shapes response quality, speed, and cost behind the scenes.

Microsoft’s in-house AI models\u003C\u002Fh2>\u003Cp>The backdrop here is Microsoft’s push to rely more on its own AI models.

Partnership questions\u003C\u002Fh2>\u003Cp>OpenAI’s statement reads like a reset of the public narrative. Rather than letting cost-cutting chatter define the relationship, the company is pointing to a concrete deployment in Copilot as proof that the partnership remains active and commercially important.\u003C\u002Fp>\u003Cp>That does not remove the strategic tension. It does, however, show how AI partnerships can look stable on the surface while both sides keep building alternatives underneath.\u003C\u002Fp>\u003Cul>\u003Cli>Signal to market: the partnership is still intact\u003C\u002Fli>\u003Cli>Signal to customers: Copilot’s model stack may keep changing\u003C\u002Fli>\u003Cli>Signal to competitors: model choice remains a live business lever\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>5. What this means for Copilot users\u003C\u002Fh2>\u003Cp>For most users, the headline matters because it hints at future behavior in Copilot rather than immediate controls they can click. If GPT 5.6 is the preferred model, users may see changes in answer style, reliability, or task handling as Microsoft rolls it deeper into the service.\u003C\u002Fp>\u003Cp>It also suggests that model competition inside \u003Ca href=\"\u002Ftag\u002Fenterprise-ai\">enterprise AI\u003C\u002Fa> products is now part of the product story.

If you care about Copilot as a user or buyer, the important part is that model choice can change without much fanfare, and those changes can affect the quality of the assistant you get.\u003C\u002Fp>\u003Cp>In short, GPT 5.6 becoming the preferred model is both a product update and a partnership message. It tells business readers to watch the model layer, not just the app layer, when Microsoft talks about Copilot.\u003C\u002Fp>","OpenAI says GPT 5.6 is now the preferred model for Microsoft 365
