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.

## Evidence

Verbatim from https://github.blog/changelog/2026-10-23-usage-metrics-api-adds-usage-from-tools-like-opencode:

> More developers now use Copilot as the model provider behind tools outside the IDE. Because those tools often don’t send editor telemetry, their usage was missing from totals_by_ide and hard to account for.
