GitHub makes Copilot Fusion multi-model routing generally available at Universe 2026
At GitHub Universe, Copilot Fusion left research preview and became available on every Copilot plan. Picking Fusion in the model picker hands each prompt to a router that decides which models to call and how to combine them, with Standard, High and Max effort levels. GitHub says Fusion Max lands near top single models on a coding-agent index at roughly half the cost.
Why it matters
Teams can stop hand-picking models per task; admins still control which models Fusion may route to, and billing stays per underlying model.
How to try it
Copilot Fusion is a routing system you select instead of a single model; it works in VS Code, the GitHub Copilot app, Copilot CLI and JetBrains IDEs on all Copilot plans, billed at each routed model's rate.
- Update VS Code (1.144+), the GitHub Copilot app, Copilot CLI or your JetBrains Copilot plugin.
- Open the Copilot model picker and select Fusion.
- Choose an effort level: Standard, High or Max.
- Org admins: set which models Fusion may use via enterprise/organization model policies, and optionally make Fusion the default via enterprise managed settings.
