Summary
Researchers propose a foundation model for LLM routing that assigns queries to the best-suited model from a diverse pool without retraining for each environment. This method improves the quality-efficiency trade-off in LLM inference by avoiding the need for local fitting or additional supervision.

What happened
Large language model (LLM) routing aims to assign each query to the most suitable model from a heterogeneous candidate pool, improving the quality--efficiency trade-off of LLM inference. Existing routers are typically learned through local fitting: a router is optimized for a particular query workload and...
Why it matters
Current LLM routers require retraining or supervision when query workloads or candidate models change, limiting flexibility. A foundation model for routing could streamline inference across heterogeneous LLMs, enhancing adaptability and efficiency.
