From the source
GitHub's Copilot usage metrics API now reports model usage from more of the tools developers use with Copilot, including tools like OpenCode that weren't previously captured in reports.
- A new totals_by_client array appears in the enterprise, organization, enterprise-user, and organization-user 1-day and 28-day reports, with each entry covering one client.
- Entries carry the client name, request_count for successful model requests, session_count for distinct sessions, token_usage for prompt and output tokens, and totals_by_model with a model_selection_mode.
- GitHub says more developers use Copilot as the model provider behind tools outside the IDE, and because those tools often don't send editor telemetry, their usage was missing from totals_by_ide; counting requests on the server closes that gap.
- The change is additive, existing fields are unchanged, and totals_by_client is an empty array when there is no usage to report.
- Access goes to enterprise owners and billing managers, organization owners, and anyone with a custom role granting the View Copilot Metrics permission, with the Copilot usage metrics policy enabled.
