Researchers have developed ProQuant, a new framework for post-training quantization of Mixture-of-Experts (MoE) large language models. This method addresses the challenges of preserving generation quality at extremely low bit budgets by considering cross-layer error propagation and mitigating routing drift. ProQuant utilizes a Prune-or-Prioritize Mixed-Precision Allocation (PoP) strategy for joint expert pruning and bit-width assignment, alongside a Routing-Consistent RMSNorm Finetune (RoCo) technique to adapt expert representations. Experiments show ProQuant surpasses existing methods in quality preservation across various generative tasks. AI
IMPACT This research could lead to more efficient storage and deployment of large language models, particularly Mixture-of-Experts architectures.
