## Summary

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, and 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 check routing performance on their own tasks and see what the assistant did.
