Copilot Fusion is generally available as a router across major GitHub coding surfaces, with a 30% discount through November 30, 2026.

GitHub made Copilot Fusion generally available in Visual Studio Code, Copilot CLI, the GitHub Copilot app, and JetBrains IDEs, subject to subscription and organization policy. Fusion is a runtime router, not a new model: it selects Single, Cascade, or Critique and can change patterns between prompts. Modes are Standard, High, and Max, plus a Fast mode limited to VS Code inline chat. There is no separate Fusion fee; each model bills at its normal rate, and paid users get a 30% discount through November 30, 2026. High and Max can use more credits. GitHub says earlier Copilot prompt-injection and RoguePilot issues were patched and do not indicate a Fusion vulnerability.

Key facts
  • Available in VS Code, Copilot CLI, the Copilot app, and JetBrains IDEs.
  • Patterns are Single, Cascade, and Critique; Fusion does not launch subagents.
  • Paid users receive a 30% discount through November 30, 2026.
  • Local routing preview can use MAI Code 1.1 Flash or Qwen3.8 Flash Next.
  • Discarding a draft does not undo file edits that draft already made.
  • Fusion is hidden if policy leaves no eligible models.
