New framework tackles MoE LLM trilemma with dynamic clustering and compression

Researchers have developed a new framework to address the trilemma faced by Mixture-of-Experts (MoE) Large Language Models (LLMs), which involves load imbalance, parameter redundancy, and communication overhead. Their method uses dynamic expert clustering and structured compression, periodically regrouping experts based on parameter and activation similarity to stabilize utilization. This approach reduces parameters by up to fivefold per group while maintaining specialization, leading to significant efficiency gains. Evaluations on GLUE and WikiText-103 show the framework matches standard MoE model quality while reducing total parameters by approximately 80%, improving throughput by 10-20%, and decreasing expert load variance by over three times.
