 We added documentation for the new Code generation tab, which is part of Copilot usage metrics. The docs now describe how to view code generation insights across your enterprise, compare user-initiated and agent-initiated behavior, and understand differences across models, languages, and modes. We also updated related conceptual and reference content for consistency and scannability. See [Viewing the code generation dashboard](https://docs.github.com/en/copilot/how-tos/administer-copilot/manage-for-enterprise/view-code-generation).
