Microsoft’s Copilot Cowork is now generally available worldwide, bringing multi-model AI agents to every organization running Microsoft 365 Copilot. The feature, which lets businesses delegate complex, long-running tasks to autonomous agents, represents a meaningful architectural shift in how enterprise AI actually works day to day.
Instead of answering one question at a time like a glorified search bar, Cowork plans and executes multi-step workflows on its own. Think managing email threads, scheduling meetings, generating documents, and posting updates in Teams, all without a human babysitting each action. Users specify outcomes. The agent figures out how to get there.
From chatbot to co-worker
Copilot Cowork was first announced on March 9, 2026, as part of Wave 3 of the Microsoft 365 Copilot rollout. A Frontier preview program opened on March 30, giving a limited group of organizations early access. The worldwide general availability, confirmed as of June 16, 2026, brings the feature to every Microsoft 365 Copilot licensee globally.
Microsoft isn’t relying solely on OpenAI’s models to power Cowork. Anthropic’s Claude models have been integrated into the system, functioning as a subprocessor to provide additional reasoning capabilities. That means Cowork can route different parts of a complex task to whichever model handles it best, whether that’s an OpenAI solution or Claude.
