GitHub Copilot

GitHub (Microsoft)
closed / Overall score: 4.3(strong)

GitHub Copilot's agent mode, which takes an assigned task and runs it as autonomous background work, planning, exploring the repository and executing changes. It orchestrates the first-party Copilot agent alongside Anthropic and OpenAI agents, and is built natively into GitHub across VS Code, Visual Studio, JetBrains and Neovim.

Scored as the agent surface; the in-IDE assistant is a separate record in ui_api. GitHub reports all-time users and no active-user figure. Verified 2026-08-13 via the GitHub Copilot product page.

Adoption

5 high confidence
5.0

GitHub Copilot has surpassed 20M+ all-time users, which Microsoft describes as "the world's most widely adopted AI developer tool"; agent mode is the autonomous surface of that base. That bands at >10M users, level 5. The 20M is an all-time cumulative count rather than an active one, and no agent-mode-specific figure is disclosed, so it stands in for an active count the product does not publish - which means the true active figure is lower, not higher.

Capability

4 medium confidence
4.0

Broad agentic feature set with frontier-model backends and best-in-class repository integration: autonomous background agents that plan, explore and execute, multi-model orchestration across Copilot, Claude and Codex, and deep GitHub, pull-request and CI integration. No SWE-bench figure is published for Copilot agent mode itself, so this is a judgment on features rather than a measurement, strong but below where a verified benchmark could take it.
