Microsoft 365 Copilot Wave 3 Adds Claude as AI Model and Launches Copilot Cowork in General Availability

My take: Wave 3 of Microsoft 365 Copilot is a real shift: it's no longer just an assistant that answers questions inside an app, but an agentic layer embedded across Word, Excel, PowerPoint, Outlook, and Copilot Chat, capable of orchestrating multi-step workflows. Microsoft also adding Anthropic's Claude alongside OpenAI models as a model option is notable: it gives users the ability to choose which AI handles their work, and gives Copilot the ability to automatically pick the best model for each task.

Copilot Cowork, now in general availability, goes further: from a single instruction it can build a presentation, pull financial data, draft emails, and schedule time on the team's calendar. That's not magic; it's automation of a process that used to take several hours and multiple people.

If you're an employee, freelancer, or run a team: how many repetitive coordination tasks could you delegate to an AI already inside the apps you use every day?
