Automatic model routing in coding assistants: what developers need to trust it
Overview
O'Reilly Radar argues that automatic model routing lets developers get more help from a fixed AI budget, but only if routing is tied to results and visible to the user.
The author cites RouteLLM, which reported more than a twofold cost reduction with minimal quality loss on its evaluated benchmarks. The author also cites SWE-Router, which uses a cheaper model's short first attempt to decide whether to switch to a stronger one. The author says developers still need to test routing performance on their own tasks and see which model the assistant used.
