Route Anything: Research on model and policy routing for general-purpose AI systems

The study proposes Route Anything, a unified framework for studying model and policy routing in general-purpose AI systems, and establishes an optimal routing theory under quality-cost trade-offs. The authors construct an omni-modal trajectory matrix covering 25 benchmarks across language, image, video, speech, coding and workplace agents, and robotic manipulation, with 452 candidate configurations and 374,401 scoring runs.
