GitHub Copilot

GitHub Copilot is Microsoft's AI coding assistant — embedded in VS Code, JetBrains, Neovim, Visual Studio, and GitHub.com itself. It started as ghost-text code completions and has expanded to include conversational chat, autonomous agent mode for multi-file tasks, and GitHub Models for experimenting with foundation models directly in the GitHub UI. In June 2026, GitHub is transitioning to a usage-based AI Credits billing model.

GitHub Copilot Overview

Plans (Free, Pro, Business, Enterprise), pricing, setup, supported IDEs, and the June 2026 AI Credits billing change.

Code Completions

Ghost text completions, multi-line suggestions, fill-in-the-middle (FIM), and how context windows work for autocomplete.

Copilot Chat

Conversational AI inside the IDE — explain code, fix bugs, generate tests, write docs, and ask questions about your codebase.

Agent Mode

Autonomous multi-step task completion — Copilot plans, edits multiple files, runs terminal commands, and iterates on failures.

GitHub Models

AI model playground in GitHub — test and compare foundation models (GPT-4o, Claude, Llama, Mistral) without leaving GitHub.com.
