Copilot Studio credits: licence exemptions, costs and deadlines
Diesen Beitrag auf Deutsch lesen
Copilot Studio moved to usage-based Copilot Credits on 3 August 2026, with legacy agents moving by 1 September.
TL;DR
Copilot Studio uses tenant-level Copilot Credits. Tenant graph grounding costs 12 credits per response, other knowledge costs 2, and tool calls cost 5. Microsoft 365 Copilot licences exempt licensed internal users only on classic harnesses. The GitHub Copilot harness bills building, testing and runtime usage, with no published new-harness rates.

Governance takeaway
- Admins/CoE: Model agent, test and evaluation consumption before deployment because credits are shared across the tenant and GitHub Copilot harness usage is billed during building and runtime.
- Leadership/Business: Compare pay-as-you-go against 25,000-credit capacity packs based on actual monthly demand, since unused pack credits reset each month.
- Security/Compliance: Identify classic versus GitHub Copilot harness agents when reviewing licence assumptions, because the internal-user exemption does not apply to the new harness.
Frequently asked questions
What does a Copilot Credit cost and how can I buy it?
One credit costs one cent by default and sits in one shared tenant pool.
Does a Microsoft 365 Copilot license exempt agents from credits?
Only on the classic harnesses. Internal users with such a license get the B2E exemption on Standard and Copilot Chat agents.
Who shares the credit budget with Copilot Studio agents?
Copilot Cowork, Dynamics 365 and Work IQ draw from the same tenant pool, so agents compete with Cowork users for one budget.
