AI pair programmer from GitHub. Inline completions, multi-line suggestions, slash commands, chat for explaining and refactoring, and agent mode that can author PRs end-to-end. Trained on public code with enterprise filters for license-safe output. Available in VS Code, JetBrains, Neovim, Visual Studio, and the GitHub web UI.
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.
Key Features
Copilot Coding Agent: triggered from a GitHub issue, spins up an isolated cloud sandbox, makes multi-file changes, runs tests, and opens a pull request — the agent operates asynchronously while engineers work on other tasks
Multi-model selection in the IDE: switch between GPT-4o, Claude Sonnet, Gemini, and other models per request without leaving VS Code, JetBrains, or the GitHub web UI — model selection surfaces in the chat interface
Copilot Chat with workspace context: answers questions about repo structure, explains functions, generates code, and writes tests with access to the full codebase rather than only the open file
PR description and code review: generates pull request summaries from the diff and adds inline review comments when enabled — reduces the description-writing step and provides a first-pass review before human reviewers engage
Enterprise admin controls: centralized policy enforcement, usage analytics per seat, IP indemnification, content exclusions for specific files or paths, and SSO/SAML integration through GitHub Enterprise
GitHub Actions integration: Copilot can trigger, monitor, and interpret CI workflow failures inline in the chat interface — surfaces the relevant log lines and suggests fixes without leaving the PR
