GitHub makes Copilot Fusion generally available at Universe 2026, routing and orchestrating models per task
At Universe 2026 on Oct 28, GitHub made Copilot Fusion generally available: users choose Fusion and a Standard, High or Max effort level, and Copilot picks and combines models for each task. GitHub says Fusion Max scored 60 on the Artificial Analysis Coding Agent Index, within two points of Claude Code with Opus 5.5 Max, at about half the cost per task.
Why it matters: Coding assistants are moving from manual model picking to systems that route work across models; the cost and speed figures are GitHub's own, and paid plans get a limited-time 30% discount on Fusion model costs.
