COMPASS: Routing via Capability-Oriented Model Profiling with Adaptive Search, Selection, and Tool Use
Compass, an agentic router in which an LLM follows a routing recipe, gathers performance and cost evidence through tools, and optionally inspects candidate answers before selecting a model, is proposed and shown to improve accuracy and lower model-call cost relative to specialized and trained routing baselines.
