LLMRouter: Unified Infrastructure for Developing, Evaluating, and Deploying LLM Routers

Tao Feng, Fangxu Yu, Haozhen Zhang +9

No single large language model (LLM) is optimal across all queries and budget constraints, making model routing essential for cost-effective deployment. Existing routers adopt dive…

BEAM: Binary Expert Activation Masking for Dynamic Routing in MoE

Juntong Wu, Jialiang Cheng, Qishen Yin +5

Mixture-of-Experts (MoE) architectures enhance the efficiency of large language models by activating only a subset of experts per token. However, standard MoE employs a fixed Top-K…

Iterative Critique-and-Routing Controller for Multi-Agent Systems with Heterogeneous LLMs

Wenzhi Fang, Liangqi Yuan, Guangchen Lan +2

Multi-agent large language model (LLM) systems often rely on a controller to coordinate a pool of heterogeneous models, yet existing controllers are typically limited to one-shot r…
