GitHub launches Copilot Fusion to route coding work across models
Original title: GitHub Launches Copilot Fusion for Smarter and Cheaper AI Coding
Paid Copilot users get a 30% Fusion discount through November 30, 2026, while High and Max can use more credits.
GitHub made Copilot Fusion generally available in Visual Studio Code, Copilot CLI, the GitHub Copilot app, and JetBrains IDEs. Fusion is a router, not a new model: it picks Single, Cascade, or Critique execution and can switch patterns mid-conversation. Tiers are Standard, High, Max, and a user-unselectable Fast mode for VS Code inline chat. GitHub says prior Copilot prompt-injection and RoguePilot issues were patched and do not show a Fusion vulnerability.
- Cascade and Critique add model calls, so they take longer than Single.
- Local models can join Fusion Standard in a public preview.
- Discarding a draft does not undo file edits that draft already made.
- Selection follows subscription, admin, data-residency, and FedRAMP limits.
- Fusion does not launch subagents.
- Vendors
- GitHub
