# GitHub Copilot

> AI coding assistant from GitHub that provides completions, chat, agent mode, code review, and a CLI across major IDEs and GitHub.com.

GitHub Copilot is GitHub's AI coding assistant. It works inside the editor, on the command line, and across GitHub.com to suggest code, answer questions, edit multiple files, and run agentic tasks. It supports a roster of models from Anthropic, Google, OpenAI, and others, and is sold in individual and business plans.

## Where It Runs

- **Editor integration** — *Runs as an extension in VS Code, Visual Studio, JetBrains IDEs, Neovim, Xcode, Eclipse, Zed, Raycast, and SQL Server Management Studio*
- **Terminal** — *Copilot CLI brings natural-language commands and workflow planning to the shell*
- **GitHub.com** — *Chat, pull request summaries, and code review are wired directly into the GitHub web interface*

## Core Coding Features

- **Inline suggestions** — *Generates line, block, and full-function completions as you type, with unlimited inline suggestions on paid plans*
- **Copilot Chat** — *Conversational assistant for explaining code, refactoring, debugging, and answering questions about open files and workspaces*
- **Agent mode** — *Multi-step task execution that can plan, edit across files, run commands, and iterate until a task is done*
- **Cloud agent** — *Assigns work to background agents (Copilot, Claude, or Codex) that operate on issues and pull requests asynchronously*

## Review and Collaboration

- **Code review** — *AI-generated review comments on pull request diffs, including coverage for users without a Copilot seat when enabled by admins*
- **Pull request summaries** — *Auto-generated descriptions of changes inside GitHub.com pull requests*
- **Copilot Spaces** — *Shared knowledge surfaces that combine repositories and documentation as context for the team*

## Models and Extensibility

- **Model selection** — *Access to models including Haiku 4.5, GPT-5 mini, Claude Sonnet, Claude Opus, and Codex, with the highest tiers unlocking the full model roster*
- **MCP and extensions** — *Integrates with Model Context Protocol servers and third-party Copilot Extensions; admins can allow-list servers for governance*
- **Custom instructions and agent skills** — *Tailor Copilot's behavior to a codebase or workflow with project-wide instructions and reusable skills*

## Plans and Usage

- **Premium request system** — *Free plan includes 50 chat/agent requests and 2,000 completions per month; Pro and Business include 300 premium requests; Pro+ and Enterprise multiply that allowance and can buy more*

## Enterprise and Trust

- **Enterprise controls** — *User management, audit logs, IP indemnity, content exclusions, single-control-plane agent governance, and policy management*
- **Privacy posture** — *Business and Enterprise data is not used to train models; individual subscribers can opt out of training*
- **Code referencing** — *Optional duplication filter detects suggestions matching public code and surfaces license information for matches*
