Technology Oct 05, 2025

Microsoft just announced some big AI updates for Microsoft 365, previewed by CEO Satya Nadella this week.
The highlight is Excel's new "Agent Mode," which lets you chat with Copilot right in your spreadsheet to build complex models—no coding needed.

You can now choose between OpenAI and Anthropic models

Teams is getting multiplayer AI, so groups can use digital assistants together during chats and meetings—think project managers or research helpers on demand.
There's also a new Knowledge Agent that pulls in relevant info from across your company's apps.
Plus, you can now pick between OpenAI and Anthropic models for research tasks, making the whole suite more flexible for how you work.
