Copilot Fusion is GA: pick an effort level, not a model
Original ~4 min → 25 sec here
The point
GitHub Copilot Fusion is generally available. Instead of picking a model for each task, you select Copilot Fusion and an effort level, and it routes and orchestrates models for you using three patterns: Single (one model), Cascade (a cheap model drafts, a check escalates if needed), and Critique (one model drafts, another reviews).
Why it matters
Model-picking per task goes away. Cost control moves to the effort level you choose and the model policies your admins set.
Key details
- Fusion Max scored 60 on the Artificial Analysis Coding Agent Index, within two points of Claude Code with Opus 5.5 Max in GitHub's comparison, at about half the average API cost per task
- Three effort levels: Standard for everyday coding, High for harder tasks, Max for the most demanding reasoning
- Available on all Copilot plans in VS Code, the Copilot app, Copilot CLI, and JetBrains IDEs; you are billed per model used, with a 30 percent discount on model costs for paid plans for a limited time
