GitHub reports an all-time cumulative user count for Copilot rather than an active-user figure, and describes it as the most widely adopted AI developer tool; agent mode is the autonomous surface of that same user base. Because no agent-mode-specific or active-user count is published, this cumulative total is used as a proxy, which means the true active figure is lower rather than higher.

  "has now reached more than 20 million users"; a GitHub spokesperson confirmed it represents "all-time users", and "Microsoft and GitHub don't report how many of these 20 million people have continued to use the AI coding tool on a monthly or daily basis".

Copilot agent mode runs autonomous background agents that plan, explore and execute, orchestrating Copilot alongside Claude and Codex with deep GitHub, pull-request and CI integration. No benchmark result is published for agent mode itself, so it is judged on features and sits a step below OpenHands, which has a verified benchmark result.
