New R&Q strategy balances SMoE LLM load without retraining

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new inference-time strategy called Replicate-and-Quantize (R&Q) to address load imbalance in Sparse Mixture-of-Experts (SMoE) large language models. This method dynamically rebalances workloads across experts without requiring retraining or modifications to the routing mechanism. Experiments show that R&Q can reduce imbalance by up to 1.4x while maintaining accuracy, making SMoE models more efficient and predictable for deployment. AI

IMPACT Improves efficiency and predictability of SMoE LLM inference, potentially lowering deployment costs.

    A Replicate-and-Quantize Strategy for Plug-and-Play Load Balancing of Sparse Mixture-of-Experts LLMs

    arXiv:2602.19938v2 Announce Type: replace Abstract: Sparse Mixture-of-Experts (SMoE) architectures are increasingly used to scale large language models efficiently, delivering strong accuracy under fixed compute budgets. However, SMoE models often suffer from severe load imbalanc…
