Metered usage for Copilot Coach agents

At the end of October 2024, Microsoft introduced five Copilot Coach agents.

• Prompt Coach
• Writing Coach
• Career Coach
• Idea Coach
• Learning Coach

Microsoft mentions in the announcement:

These Copilot agents, created by Microsoft, extend the native capabilities of Microsoft 365 Copilot with instructions and knowledge sources relevant to each use case. They will be available to Microsoft 365 Copilot licensed users from early October 2024. Make sure to check the Teams App Store or use the Microsoft 365 Admin Center to deploy them within your organization.

These agents have been available in the Integrated Apps and Teams apps since November 2024.

Microsoft documentation does not provide any further information about the Coach agents except for the introduction.

I do not use a Microsoft 365 Copilot license in my tenant, so I was surprised when Prompt Coach and Writing Coach responded.

I asked Copilot for information on whether Prompt Coach now supports “Metered usage” for accounts with no Copilot license.

It is a demonstrably wrong information.
In my tenant, Copilot Studio is still configured with Pay-as-you-go (PAYG) from my testing to evaluate PAYG billing. For accounts without a Microsoft 365 Copilot license and if they use Copilot Studio agents, Copilot Studio uses either a message package (25,000 messages per month) or PAYG via an Azure subscription.

I noticed that Copilot Studio charges for new usage after my Prompt and Writing Coach test.

A download confirms the timing aligns with my tests.

Two resource IDs are noted in the download. The resources cause the costs.

• P_f0ff38f1-4d81-a9b7-dbf1-b161328daa1f
• P_e3d64609-7a28-6de6-3093-402c20bb96ce

An analysis in the browser confirms that the IDs refer to the two Coach agents. The resource ID is linked to an agent.

Identical for Writing Coach.

Information from the five coach agents summarized.

It also proves Copilot Coach agents use Metered Usage for accounts with no Microsoft 365 Copilot license, even if Copilot continues to claim otherwise.
