Route Anything framework studies routing across specialized AI models

They report that ideal per-input routing beats the best single fixed candidate by 5.4 points, and that learned routers beat it by 0.3 points across 16 benchmarks, 2.1 points on video generation and 1.1 points on robot manipulation while using 24% less policy time. Routing raised efficiency 8.82x on average over the reference model. The paper is available on arXiv.
