  GitHub Copilot proprietary product, agent mode autonomous task execution, third-party model support

GitHub Copilot surpassed 20M+ all-time users (Microsoft July 2025 earnings): 'world's most widely adopted AI developer tool.' Agent mode is the autonomous surface of that base. >10M band. Note: 20M is all-time, not active; agent-mode-specific count not disclosed, but base scale firmly supports level 5.

  20M+ all-time users confirmed on Microsoft earnings call (corroborating)

Broad agentic feature set with frontier-model backends and best-in-class repo integration; no published SWE-bench for Copilot agent mode itself, so feature_matrix at 4, strong but below a verified-benchmark ceiling.
