GitHub launches Copilot Fusion, which picks and routes models for each task
At its Universe conference (Oct. 28), GitHub introduced Copilot Fusion, which automatically routes each task to a selected model or mix of models. GitHub says the system delivers near-frontier performance at half the cost; according to The New Stack, agents already start 40% of pull requests.
Who is affected and how
- tech lead
- Compare Fusion's cost and quality with your current fixed model choice, and update the team's Copilot settings accordingly.
- CTO
- Automated model selection affects licence and token cost planning, so budgets need to be recalculated.
- senior developer
- Model choice is taken out of your hands, so check which tasks Fusion handles with predictable results.
