Microsoft has announced the general availability of Copilot Cowork for commercial customers, a new AI productivity agent designed in collaboration with Anthropic that completes multi-step tasks on its own. Users can switch between Copilot Chat and Cowork via a toggle, and Cowork now supports multiple AI models, additional business-system plugins, custom skills, image creation, branded PowerPoint templates, browser-based actions, and push notifications for long-running tasks. Microsoft 365 Copilot now uses Work IQ to provide more meaningful answers from organizational data sources, allowing users to ask questions in natural language and receive insights directly from Power BI reports and semantic models. Copilot can also retrieve and analyze data stored in Dataverse, a feature expected to hit general availability in September. A new “deep citations” feature links Copilot responses directly to specific sections of source files, currently supporting PowerPoint and Word files. IT admins gain new controls via the Cost Management Dashboard in the Microsoft 365 admin center, enabling them to activate, manage, and optimize spending on AI experiences, allocate credits, create spending policies and usage limits for specific groups, and select between prepaid credits and pay-as-you-go billing models.
