GitHub puts agent orchestration in one app: Fusion Max lands within two points of Opus 5.5 Max at half the cost
GitHub used Universe 2026 to release a GitHub Copilot app built for agentic software delivery, gathering agent work across projects and repositories into one surface, alongside multi-model orchestration called Copilot Fusion. GitHub reports that on the Artificial Analysis Coding Agent Index, Fusion Max scored within two points of Opus 5.5 Max at half the cost and 40% less time per task. Copilot projects, session continuity and Copilot automations that learn from outcomes separate execution management from decisions.
