In March, Microsoft unveiled Copilot Cowork, an agentic AI feature within Microsoft 365 Copilot that lets users delegate tasks to the AI for background execution. After a brief research preview with a select customer cohort, the company rolled out Copilot Cowork to its Frontier program on March 30.
Today, Microsoft confirmed that Copilot Cowork is now globally available to all Microsoft 365 Copilot users, noting that it has become the fastest‑growing feature ever seen in its Frontier program.
Distinct from standard Copilot Chat, Copilot Cowork can execute intricate, extended, multi‑tool workflows entirely in the cloud, leveraging organizational context via Work IQ. Microsoft asserts that, relative to Claude Cowork, its solution will average 30‑40% lower cost when using the Microsoft 365 connector.
Currently, Copilot Cowork operates on Anthropic models such as Opus 4.8 and Sonnet 4.6, while Frontier users now have access to GPT‑5.5. Additionally, Microsoft revealed Cowork 1—a secure, fine‑tuned model slated for release in the coming weeks—intended to manage routine Copilot duties more affordably.
Microsoft has rolled out a new billing model for its Copilot Cowork feature, which now requires a Microsoft 365 Copilot subscription. Users will be charged separately through Copilot Credits, with rates set at $0.01 per credit. The cost reflects the model’s usage, including context retrieval, tool calls, and runtime. To give IT teams granular control, Microsoft offers spending limits, usage alerts, user‑level controls, comprehensive reporting, and prepaid usage plans for organizations. Billing based on usage starts today, though Frontier customers who accessed Cowork between March 30 and June 16 will see their first charge on July 1, 2026.
The Microsoft 365 Copilot app now features a simple toggle that unlocks the full Cowork experience. In addition, Microsoft is expanding its partner ecosystem, with Enosix, Harvey, LSEG, Miro, monday.com, Moody’s, Morningstar, S&P Global Energy, and TeamsMaestro already integrated. Upcoming releases will bring Adobe, Atlassian, Box, Canva, Databricks, and other major players into the fold.
