What is GitHub Copilot

GitHub Copilot remains one of the most practical AI platforms for developers because it meets them where they already work: inside editors, repositories, pull requests, and terminal workflows. It is not trying to be a general-purpose productivity suite first. It is trying to make software teams faster.

GitHub Copilot helped define the modern AI coding-assistant category after its early launch in 2021, and it has since expanded from autocomplete into chat, review, and agent-like coding workflows. Its history matters because the product’s credibility comes from being one of the earliest AI tools to find daily workflow adoption among professional developers.

Core offerings

  • Inline code completion and next-edit suggestions.
  • Chat, agent mode, cloud agent, and code review capabilities.
  • Support across GitHub, VS Code, Visual Studio, JetBrains, Xcode, Neovim, and more.
  • Model selection and usage-based billing via GitHub AI Credits.

Pricing

GitHub currently lists Copilot Free at US$0, Pro at US$10 per user per month, Pro+ at US$39 per user per month, and Max at US$100 per user per month. Organisation pricing includes Copilot Business at US$19 per user per month and Copilot Enterprise at US$39 per user per month. GitHub measures many AI features in AI Credits, with 1 AI credit equal to US$0.01.

Model footprint

Copilot now exposes a broader model catalogue than its original single-model positioning suggested. Public plan pages reference access to GPT-5 mini, Haiku 4.5, premium models such as Opus on higher tiers, and third-party agents including Claude Code and Codex.

Why select GitHub Copilot

Copilot is a strong default choice when the primary user is a software engineer rather than a general knowledge worker. It is especially compelling when you want AI inside coding workflows, pull requests, and repository context rather than in a separate general-purpose chat tab.

Model disclosure note

GitHub Copilot is a coding surface with model selection and agent features, not a single model family. GitHub’s public docs are clearer on plans, AI credits, and environments than on one immutable live model matrix.
