Microsoft's CEO confirmed 20M all-time Copilot users on an earnings call in July 2025; the free tier opened to 150M GitHub developers in December 2024; and paid subscribers stood at roughly 4.7M by January 2026. That puts it above 10M users, level 5 on the active-user scale. The 20M is an all-time count rather than an active one, and the one genuinely active-adjacent figure available, the 4.7M paid subscribers, would sit a band lower at level 4 - worth stating plainly rather than leaving hidden behind the label.

The most widely adopted and feature-complete AI developer assistant: chat, inline completion, agent mode and multi-model selection, deeply integrated into the IDE and GitHub, with enterprise controls. It defines the frontier for in-IDE assistants. The surface also includes a CLI, GitHub-native and custom agents plus third-party ones over MCP servers, Copilot Spaces for shared repository and document context, and enterprise-grade governance controls.
