Copilot

Copilot is an AI-powered productivity tool integrated into Microsoft 365 and GitHub's Visual Studio Code. In Microsoft 365 Copilot, it uses GPT-5.6 as its preferred model to assist in Word, Excel, PowerPoint, Chat, and Cowork. The tool helps users write code and draft content more efficiently. It is available to Microsoft 365 customers and developers using the Visual Studio Code extension. Users include enterprise professionals and individual developers working in office and code environments.

Microsoft has confirmed that GPT-5.6 is now the preferred model in Microsoft 365 Copilot, enhancing AI capabilities across core productivity apps like Word, Excel, and PowerPoint. This update is detailed in an OpenAI blog post that explains how the model improves performance in these applications. A report from Digital Trends notes that few paid Microsoft 365 customers have adopted the product, and even fewer are actively using it. The discrepancy between the model upgrade and low adoption remains a key point in the discussion. The trend reflects a continued focus on embedding AI into productivity workflows, though real-world usage remains minimal. The evidence shows a clear technical update with limited user uptake.
