Beyond Accuracy and Cost: Latency-Aware LLM Query Routing for Dynamic Workloads

Shivam Patel, Akaash R. Parthasarathy, Ankur Mallick +1

Modern language query routers improve inference efficiency by assigning each query to a model that balances response quality and monetary cost. However, current query routers are l…

Federate the Router: Learning Language Model Routers with Sparse and Decentralized Evaluations

Baris Askin, Shivam Patel, Anupam Nayak +4

Large language models (LLMs) are increasingly accessed as remotely hosted services by edge and enterprise clients that cannot run frontier models locally. Since models vary widely…

ProxRouter: Proximity-Weighted LLM Query Routing for Improved Robustness to Outliers

Shivam Patel, Neharika Jali, Ankur Mallick +1

Large language model (LLM) query routers are critical to modern AI platforms as they seek to improve efficiency by assigning inference queries to accurate, yet low-cost models. Par…
