What’s new for Copilot – September 2025
September brought another wave of updates for Copilot across Microsoft 365, but one stands out as a true game changer: Copilot now supports models beyond GPT. This marks a major step toward giving organizations more flexibility and choice in how they leverage AI within Microsoft’s ecosystem.
The first implementation of this shift is already here—Anthropic’s Claude models (Opus 4.1 and Sonnet 4) are now available in Copilot Researcher and Copilot Studio, alongside OpenAI models. This opens the door to a multi-model future where users can pick the best AI for their needs. Rollout began on September 24, with Anthropic models in preview and governed by Anthropic’s terms. Don’t miss the details in this article—there’s plenty more AI innovation to explore across your favorite Microsoft 365 apps.

Quickly grasp the key topics, summaries, and insights from your Copilot Notebooks – without having to dig through every document or detail.
Library is a central, visual-first space in the Microsoft 365 Copilot app where users can easily access their Copilot-generated content like images and pages – as well as Copilot-generated content shared with them.
A picture is worth a thousand words. Before, Copilot Studio agent builders would need to use the default icon or manually upload their own image. This process meant browsing the web for an image, asking different teams for icons, or manually drawing one. Users can now use AI to describe how the icon should look like, thus helping inform end users of the agent’s function more easily, with more expression. Users can now generate icons using AI in the lite version of Copilot Studio in M365. Users can enter custom prompts or use the description of the agent to generate the icon. Alternatively, users can manually upload their own icon or select from a set of pre-created icons. Icons are capped at 1 MB (192px).
Starting October 2025, the Microsoft 365 Copilot app for Windows will show a non-blocking “Update available” button, allowing users to update immediately or later without interrupting use. No admin action is needed, and the update ensures access to new features and improvements.
