GitHub Copilot
Code AssistantGitHub's AI pair programmer with agent mode, multi-model support and IDE integration for completions, chat and automated fixes.
How It Works
As you type in your editor, Copilot's model predicts likely completions from your current file and related open files, shown as inline suggestions you accept with a keypress. Copilot Chat answers questions about your code in a side panel; Agent mode extends this to autonomous multi-step tasks - planning a change across files, running tests, and opening a pull request - while newer plans let you pick which underlying model (including premium ones like Opus) handles a given request.
Free tier (2,000 completions/mo); Pro $10/mo; Pro+ $39/mo; Max $100/mo; Business $19/user/mo; Enterprise $39/user/mo - code completions never consume credits on paid plans, only premium chat/agent requests do
