Copilot Cowork Now Generally Available
- Read time: 5 mins.
Microsoft has officially launched Copilot Cowork. With the preview period ended, starting July 1, 2026, Cowork will stop working for any tenant that has not set up usage-based billing.
This article explains what Cowork is, how the new billing model works, and what you need to do as an admin.
What Is Copilot Cowork?
Copilot Cowork is an agentic AI experience built into Microsoft 365 Copilot. It is designed for complex, long-running, multi-tool tasks, the kind of work that usually takes hours to do manually and that standard Copilot chat isn’t built to handle end-to-end.
Where Copilot chat generates a draft or a recommendation, Cowork will execute. Users define the work and Cowork runs it, using the tools it needs to return a completed result.
Examples from Microsoft’s Frontier preview period:
- An engineering team automated batch-job spreadsheet edits and dependency flow chart generation after every change, eliminating work that previously required careful manual intervention.
- One team compared nearly 4,000 files across two product versions in a fraction of the time it would have taken manually.
- A sales lead used Cowork to analyze a stalled pipeline and receive a ranked list of at-risk opportunities with the specific follow-up that had gone cold on each account.
Cowork runs in the cloud, not locally. Files are not stored on user devices. Tasks keep running even when a user’s laptop is off. All activity still operates within your existing Microsoft 365 security and compliance boundary. Audit logs, eDiscovery, Insider Risk Management, and sensitivity label inheritance are all supported at general availability.
What Changed at General Availability
Cowork was previously available only through Microsoft’s Frontier program, which gave early access to a limited group of customers. Now, Cowork is available worldwide to all Microsoft 365 Copilot subscribers (excluding GCC tenants as FedRAMP compliance is not yet supported).
With that availability comes a shift in how Cowork is billed.
During the Frontier preview period, Microsoft did not charge for Cowork usage. That grace period ends July 1, 2026. After that date, any tenant without usage-based billing configured will lose access to Cowork.
If your organization had at least one user active in the Frontier program before June 16, this deadline applies to you directly.
How Copilot Cowork Usage-Based Billing Works
Cowork is not included in the base Microsoft 365 Copilot User Subscription License (USL). The USL covers Copilot Chat, Copilot in Word, Excel, PowerPoint, Outlook, and Teams, and features like Researcher and Analyst agents. Cowork sits on top of that, billed separately on a usage basis.
The currency is Copilot Credits.
Each task a user runs in Cowork consumes credits. The number of credits consumed depends on four inputs:
- Model use: which AI model handled the task
- Context retrieval: how much organizational data was accessed
- Tool calls: how many tools Cowork invoked to complete the task
- Runtime: how long the task ran
Microsoft categorizes tasks into three tiers:
- Light tasks use a small number of sources, limited reasoning, and produce one output or fewer.
- Medium tasks draw on multiple sources, apply structured reasoning, and generate two or more outputs.
- Heavy tasks aggregate broadly, apply deep reasoning, and produce many outputs.
Your actual credit spend will depend on how your users work and which task types they run most frequently. Microsoft provides a Customer Cowork Estimator to help you model usage before you enable billing.
Payment Options
You have two ways to pay for Copilot Credits:
- Pay-as-you-go (PayGo): $0.01 per credit. No upfront commitment. Billed based on actual usage.
- Prepaid (P3): Commit to a usage volume in advance in exchange for a discount off the PayGo rate. It is important to note that the prepaid plan requires an annual subscription.
For organizations just getting started, PayGo gives you flexibility while you establish your usage baseline. P3 makes more sense once you have a clear picture of consumption.
Cost Management Controls Admins Should Know
Microsoft built a cost management layer directly into the Microsoft 365 admin center. Before you enable billing, take time to configure these controls. They are your guardrails against unexpected spend.
Spending limits can be set at the tenant, group, and user levels. You define the budget. Cowork stops charging when that limit is hit.
Usage alerts notify designated admins when spend crosses a threshold you set. You choose the thresholds and who receives the alerts.
Usage reporting gives you visibility at the tenant, group, and user level. You can drill into which users are running the most tasks and what those tasks are costing.
User-initiated credit requests let users ask for additional credits from inside Cowork when they hit a limit, rather than going around it.
The Cost Management dashboard is in the Microsoft 365 admin center. You can set limits and define budgets before any usage accumulates, which means you can enable billing safely and adjust from there.
HBS Tip: Make Credit Usage Visible at the Task Level
Tell your users to end any Cowork process with a final message of /cost.
Cowork will return the number of credits consumed in that session, giving users immediate visibility into what each task actually cost. This is one of the fastest ways to build cost awareness across your team before spend becomes a problem.
What Admins Should Do Now
- Go to the Microsoft 365 admin center and open the Cost Management dashboard.
- Enable usage-based billing. Connect to an Azure subscription to support billing at scale.
- Set spending policies. Define budgets at the tenant, group, and user levels before usage begins.
- Configure alerts. Set thresholds so you’re notified before spend gets away from you.
- Use the Cowork Estimator (aka.ms/CustomerCoworkEstimator) to model expected credit usage based on your user personas and task mix.
If you’re not sure whether your organization has users active in Cowork, check your Microsoft 365 admin center usage reports.
A Note on Copilot Model Choice
At general availability, Copilot Cowork runs on Anthropic models: Opus 4.8 and Sonnet 4.6. Customers in the Frontier program can also access GPT 5.5.
Microsoft will be releasing a new model called Cowork 1, post-trained specifically for Cowork tasks at a lower cost per task. Once available, Cowork 1 will be the efficient default for cost-sensitive workloads, with frontier models available when the task warrants it.
Admins in Frontier also have access to a model picker, which lets users select the model for a given task.
