GitHub makes 'Copilot Fusion,' which automatically picks and combines models per task, generally available; local model routing in experimental preview

Announced October 28, 2026

Verified (fact)

GitHub made 'Copilot Fusion' generally available at its annual event, GitHub Universe 2026. Instead of users choosing a model for each task, selecting Fusion lets Copilot decide which models to use and how to combine them. On the same day, a routing feature that lets Fusion choose between on-device local models and cloud models was released as an experimental preview. Electronic Times (Korean daily) reported that the feature compares models on performance and cost to make its choice.

Needs fact-check (claim)

GitHub said Fusion intelligently routes and orchestrates models to fit the task. According to Electronic Times, GitHub says it speeds up development while also reducing AI usage costs.

Why it matters (interpretation)

Coding tools have begun handling model selection themselves rather than leaving it to users. The routing layer may come to have a bigger impact on cost and quality than individual model providers. With local models now included as routing targets, hybrid setups also become possible.
