GitHub made Copilot Fusion generally available on 28 October 2026 at its Universe conference. Instead of picking a model, developers choose Fusion and an effort level, and Copilot routes each prompt to one or more models. GitHub says Fusion Max scored 60 on the Artificial Analysis Coding Agent Index, two points below Claude Code with Opus 5.5, at about half the cost per task. It works on all Copilot plans, with a temporary 30% discount.
