Microsoft bills Copilot by usage and ships a spend governor with it

Microsoft has unveiled its Copilot super app, three tabs covering chat, code and agents. Home merges chat with Cowork, Code lets any employee build and share an internal app, and Autopilot is the assistant Microsoft called Scout in May, now working in the cloud overnight. Read past the feature list and you reach the line that changes what Copilot costs.

“Just as Office defined work for the PC era, the new Copilot is built to define it for the AI era.”

The flat licence still covers Copilot in Word, Excel, PowerPoint, Outlook and Teams. Everything agentic moves to usage-based billing: Microsoft charges for what Cowork, Code and Autopilot consume, and for time spent on the heavier models. Alongside them it shipped FinOps for AI, a console the company describes as the way admins stop agentic usage getting out of control. Microsoft built that limiter before a single customer asked for one, which is the company's own estimate of how fast an always-on agent runs up a bill.

Two other companies answered the same question this week:

• OpenAI sells advertising: ChatGPT Ads passed a $1bn annualized run rate in under 200 days.
• Meta takes a cut: Muse is free on tokens and earns a small fee from transactions.
• Microsoft bills consumption: Cowork, Code and Autopilot are charged by usage, not by seat.

Each one bills a different party. OpenAI charges the people who do not subscribe, since ads run only on the free and Go tiers. Meta charges the merchant, taking a cut of the purchase its agent completes. Microsoft charges the employer by the minute. No two of them reach for the same wallet.

Identity is the part enterprises will examine

Autopilot lives in the customer's tenant with its own identity, memory, computer and workspace, turns up in Teams and Outlook, and you @mention it like a colleague, with permissions, audit and governance behind it. That architecture also describes the thing that goes wrong: an AI agent holding credentials inside a corporate directory. We measured how long one such failure took to surface, and the answer was 84 days from an agent reaching a government portal to the government hearing about it. An audit trail is what shortens that number.

Code may matter more. Any knowledge worker can create an app, tracker, dashboard or automation and publish it to colleagues as a cloud-hosted internal tool, sandboxed inside the tenant, built on the same technology as GitHub Copilot. Shadow IT with permissions and an audit log beats shadow IT without them. It also means the count of internal applications a company runs stops being a number its IT department sets.

Office had no competition

Office defined work for the PC era against almost nothing. Copilot enters a market where, by The Verge's own assessment, it has already lost the consumer battle to rivals, and where the commercial customers Microsoft counts on are slow to show interest. Home and Code reach early access in the coming weeks, Autopilot enters private preview this month, and Microsoft has published no usage rates. The price of running an agent all night is the number to wait for.

Informational material, not investment advice. Home and Code reach early access in the coming weeks, Autopilot enters private preview this month, and no usage rates were published.
