M365 Copilot licensing

A recent question was asked about Microsoft M365 Copilot licening. Does a tenant need to license all users or is a subset of users available?

M365 Copilot is like any other workload, you see the licenses in the admin center and can assign them to individuals or groups using the GUI or PowerShell.

From the How to prepare for Microsoft 365 Copilot page:

"As with other apps and services, admins will be able to manage Microsoft 365 Copilot licenses using the Microsoft 365 admin center (under Billing > Licenses). Here, you can assign a license to individual users or multiple users. You can also assign licenses to users by group membership in Azure Active Directory, and assign Microsoft 365 licenses to user accounts with PowerShell."
