Dynamic Expert Quantization for Scalable Mixture-of-Experts Inference

arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • A new system called DynaExq has been introduced to enhance the efficiency of Mixture-of-Experts (MoE) models by dynamically managing expert precision during inference. This approach addresses the limitations of static post-training quantization, which often leads to accuracy loss due to fixed activation patterns. DynaExq employs a hotness-aware precision controller, an asynchronous precision-switching pipeline, and a fragmentation-free memory pooling mechanism to optimize resource allocation.
  • The implementation of DynaExq is significant as it allows for scalable deployment of large language models (LLMs) on consumer GPUs, overcoming the challenges posed by the large memory footprint of inactive experts. By aligning expert bit-widths with activation statistics, DynaExq ensures that memory budgets are adhered to while maintaining model performance, which is crucial for real-time applications in AI.
  • This development reflects a broader trend in AI towards optimizing resource management in complex models, as seen in various frameworks that aim to improve the adaptability and efficiency of MoE architectures. Innovations such as dynamic routing and on-demand expert allocation are becoming increasingly important as the demand for scalable AI solutions grows, highlighting the ongoing evolution in the field of machine learning.
