TL;DR

  • GitHub Copilot is the AI pair programmer from GitHub - code completions, function generation, conversational assistance, and an agent mode that can plan and execute multi-file changes
  • Works across VS Code, Visual Studio, JetBrains IDEs, Neovim, Xcode, and the GitHub.com editor
  • Now multi-model: routes between OpenAI’s GPT-5 family, Anthropic’s Claude Sonnet and Opus, Google’s Gemini, and several open-weight options depending on the task and plan
  • Tiered pricing: a Free tier with capped usage; Pro at $10/month; Pro+ at $39/month for heavier frontier usage; Business at $19/user/month; Enterprise at $39/user/month with org-wide controls
  • The original mainstream AI coding assistant - now competing with Cursor, Cline, and Claude Code on agentic depth
  • Best when your team already lives inside GitHub - the integration with Pull Requests, Issues, Actions, and the GitHub.com agent surface is the differentiator

GitHub Copilot is an AI pair programmer developed by GitHub, originally launched in partnership with OpenAI. It provides code completions, suggestions, and AI-powered development assistance across multiple IDEs.

GitHub Copilot is now multi-model. Depending on your plan and the task, it can route to OpenAI’s GPT-5 family, Anthropic’s Claude Sonnet and Opus models, Google’s Gemini, and a selection of open-weight options - rather than being locked to a single underlying model the way it was at launch.
