GitHub Copilot Fusion: what's new (October 28, 2026)

GitHub Copilot Fusion is generally available in the Copilot model picker, with Standard, High, and Max effort and Single, Cascade, and Critique patterns, on all Copilot plans in VS Code, the Copilot app, Copilot CLI, and JetBrains. GitHub says usage is billed per model used, with a 30% discount for a limited time on paid plans, and a same-day note says local-model routing is an experimental preview. The changelog's coding-index comparison is a vendor claim.
