GitHub Copilot

AI coding assistant built by GitHub (Microsoft). Started as inline code completion in VS Code (2021 technical preview, GA June 2022), expanded to chat (2023), then to agentic and multi-file capabilities (2025–2026). As of June 2026, 20M+ global users across individual and enterprise plans.

History

  • 2021: Technical preview as code completion only; trained on public GitHub repos
  • 2022: GA launch at $10/month individual, $19/user/month business
  • 2023: Copilot Chat added; JetBrains, Vim, Neovim, Visual Studio support
  • 2025: Copilot Workspace enters beta; agent mode added to VS Code
  • 2026: Copilot Workspace reaches GA; Project Polaris announced; new GitHub Copilot desktop app announced at Microsoft Build

Copilot Workspace

Browser-native agent (GA 2026). Works from a GitHub issue or PR description without requiring an IDE. Reads the repository, proposes multi-file edits, runs tests, and iterates — then opens a PR for human review. Enterprise customers can enable Autonomous Agent Mode (available July 2026), which writes, tests, and commits entire feature branches; all changes require human approval before merging.

Project Polaris

Microsoft's in-house AI coding model, built on a mixture-of-experts architecture. Replaces GPT-4 Turbo as the default Copilot engine starting August 2026, with automatic migration for all subscribers and an optional three-month fallback period. Benchmarked above GPT-4 Turbo on HumanEval and MBPP, with noted gains in low-resource languages (Rust, Haskell). Prior to Polaris, Copilot routed through GPT-4 Turbo; users can also select other models from a catalog including Claude and Gemini variants.

Editor Support

Available in: VS Code, JetBrains (IntelliJ, PyCharm, etc.), Vim, Neovim, Visual Studio, Azure Data Studio, and as gh copilot in the GitHub CLI.

Pricing (June 2026)

GitHub Copilot moved to usage-based billing on June 1, 2026. Plans include monthly GitHub AI Credits; one credit equals one cent of model usage.

Plan Price Credits/month
Free $0 Limited completions
Pro $10/month 1,500
Pro+ $39/month 7,000
Business $19/user/month 1,900/user
Enterprise $39/user/month 3,900/user
Max $100/month Heavy agentic use

GitHub Copilot for CLI

gh copilot is a CLI integration that explains shell commands and suggests commands from natural language. Ships as part of the GitHub CLI (gh). Separate from the IDE extension but shares the same Copilot subscription.

Strengths

  • Deepest GitHub integration: reads issues, creates PRs, understands repo history
  • Broadest editor support — the only AI coding tool in JetBrains, Vim, and Neovim by default
  • Enterprise features: SSO, audit logs, policy controls, IP indemnification at Business/Enterprise tiers
  • No separate tool to install for VS Code users; built into GitHub's native workflow

Weaknesses

  • Less autonomous than claude-code for long-running tasks — designed for human-in-the-loop
  • Model access is routed through GitHub, not direct API — less control than cline
  • Credit-based billing can be opaque for teams doing heavy agentic work
  • Copilot Workspace (browser agent) is separate from IDE agent — context is not shared
