 **RouterArena** is an open evaluation platform and leaderboard for **LLM routers** — systems that automatically select the best model for a given query. As the LLM ecosystem diversifies into specialized models of varying size, capability, and cost, routing has become essential for balancing performance and efficiency. Yet, unlike models, routers currently lack a unified evaluation standard that measures how well they trade off accuracy, cost, robustness, and latency.
