Microsoft is now making Copilot Cowork generally available worldwide—the AI agent that fully handles complex, time-consuming multi-tool tasks is now available to all Microsoft 365 Copilot customers.
Part of our AI Agents Guide. For the full picture, see our complete AI Agents Guide.
What is Copilot Cowork?
After a three-month preview in the Frontier program, Copilot Cowork has already attracted more than half of the Fortune 500 as users —including Accenture, Capital Group, Koch, and Zurich Insurance. And this is just the beginning.
Copilot Cowork isn’t a typical AI chatbot. The difference: You specify the task—Cowork handles it entirely and delivers a finished result. Instead of the AI simply providing answers via chat, the AI agent independently carries out the entire task—for example, reading files, entering data into Excel, uploading files to the web, creating an entire website, and much more.
Real-world examples illustrate what this means:
- A product team used AI to compare nearly 4,000 product files based on their software’s product versions and generated a complete to-do list, which the AI then worked through—work that would otherwise have taken weeks.
- A sales lead used AI to analyze a stalled pipeline and received a prioritized list of at-risk deals—including the exact follow-up needed for each one that had gone cold. A week’s worth of work compressed into a single morning.
- A software engineering team used AI to automate numerous batch job tables and automatically generates dependency flowcharts as documentation after every change—saving several weeks of manual work.

What Makes Copilot Cowork Special
Five factors set Cowork apart from other AI agents:
- Cloud hosting: Tasks continue to run even when your laptop is off. Files aren’t stored locally.
- Work IQ: Cowork understands your corporate context—emails, documents, meetings—and works with it.
- Enterprise security: All prompts and responses go through existing Microsoft 365 compliance controls (Audit Log, eDiscovery, Insider Risk Management).
- Multi-Model: Cowork selects the right model for each task. Currently: Anthropic Opus 4.8 and Sonnet 4.6; soon, its own “Cowork 1” model as well.
- Lower Costs: According to Microsoft, Copilot Cowork is, on average, 30–40% cheaper than Claude Cowork with the Microsoft 365 Connector.
Our article on Microsoft Open Agentic Web explains how Microsoft is positioning itself in the AI agent space in general.
Pricing and Billing
Copilot Cowork requires the Microsoft 365 Copilot User Subscription License (USL) as a foundation. In addition, billing is usage-based and calculated in Copilot Credits.
The cost per task is determined by four factors: Model Use, Context Retrieval, Tool Calls, and Runtime. Two payment options are available:
- PayGo (Pay-as-you-go): $0.01 per Copilot Credit – maximum flexibility.
- P3 (Prepaid): Commit to a volume in advance and secure a discount.
Three task types help with budgeting:
- Light Tasks: Few sources, simple reasoning, one output.
- Medium Tasks: Multiple sources, structured reasoning, 2 outputs.
- Heavy Tasks: Broad aggregation, deep reasoning, many outputs.
Microsoft provides a free budget calculator (Excel spreadsheet) directly: Download the Cowork Cost Estimator.
Important for Frontier users: Anyone who used Cowork between March 30 and June 16, 2026, will receive a grace period—billing will not begin until July 1, 2026.

FAQ: Copilot Cowork
How much does Copilot Cowork cost?
