GitHub Copilot

GitHub Copilot is an AI coding assistant that provides contextualized assistance throughout the software development lifecycle, from inline suggestions and chat assistance in the IDE to code explanations and answers to docs in GitHub. It integrates with leading editors and is natively built into GitHub.

GitHub Copilot Free is a free pricing tier with limited functionality for individual developers. Users assigned a Copilot Business or Copilot Enterprise seat are not eligible. Users with access to Copilot Pro through a paid subscription, trial, or existing verified OSS, student, faculty, or MVP account may elect to use Free instead.

GitHub Copilot is trained on all languages that appear in public repositories, with suggestion quality depending on the volume and diversity of training data for each language. It is available as an extension in Visual Studio Code, Visual Studio, Vim, Neovim, the JetBrains suite of IDEs, and Azure Data Studio. Inline suggestions are available across these extensions, while chat is currently available only in Visual Studio Code, JetBrains, and Visual Studio. It is also supported in terminals through GitHub CLI and as a chat integration in Windows Terminal Canary.

No, GitHub Copilot generates suggestions using probabilistic determination. The AI models may be trained on public code but do not contain any code, and they are not copying and pasting from any codebase. To generate a suggestion, the extension examines code in the editor and sends context to the model to make a probabilistic determination of what is likely to come next.
