Runtime is billed on usage (new, June 2026): a Copilot Studio agent that grounds in your M365 data via the Work IQ API (GA June 16, 2026) is metered in Copilot Credits — Microsoft's unified consumption meter ($0.01 per credit pay-as-you-go). The licence is the access gate; agent runtime is billed on top via Copilot Credits / Foundry tokens. See Usage billing below.

| Document producer | Generates structured outputs (reports, checklists, briefs) from a consistent template | Recurring deliverables with a fixed format |
