GitHub Copilot is an AI coding assistant integrated into GitHub and supporting editors. The 2025–2026 version covers inline code completion, Copilot Chat with workspace context, PR description generation, inline code review, and the Copilot Coding Agent — which operates asynchronously from a GitHub issue, runs in an isolated cloud sandbox, and produces a pull request without synchronous IDE interaction.
Model selection allows per-request switching between GPT-4o, Claude Sonnet, Gemini, and other models from within VS Code, JetBrains, and the GitHub web UI. Feature parity across IDEs is uneven: VS Code receives capabilities first, with JetBrains and other editors trailing.
Enterprise and Business plans provide centralized policy enforcement, per-seat usage analytics, IP indemnification, content exclusions for specific file paths, and SSO/SAML through GitHub Enterprise. Pricing: Individual ($10/month), Business ($19/user/month), Enterprise ($39/user/month); free tier with usage limits exists.
