ProQuant: Preserving Expert Quality over Quantity in Ultra-Low-Bit Quantization of Mixture-of-Experts Models

Read the original on Hugging Face Trending Papers →

ProQuant is a weight‑only post‑training quantization framework designed for Mixture‑of‑Experts large language models. It introduces PoP, which jointly prunes experts and assigns mixed‑precision bit‑widths to better use a tight bit budget, and RoCo, a routing‑consistent RMSNorm fine‑tune that mitigates routing drift caused by quantization errors. Experiments show ProQuant outperforms existing methods on a range of generative tasks.

Colla-Q: Toward Collaborative Experts in MoE Quantization via Minimax Precision Balancing

The paper introduces Colla-Q, a Mixture-of-Experts (MoE) quantization technique that uses activation entropy to allocate bit-widths across experts. By balancing performance among experts, Colla-Q improves overall MoE accuracy and reduces reliance on calibration datasets. The method aims to maintain robustness and stability in quantized MoE models.

WINDQuant: Weight-Informed Neural Decision-Making for Global Mixed-Precision LLM Quantization

arXiv:2605. 26660v2 Announce Type: replace Abstract: Quantization is an effective approach to reduce the memory footprint and inference cost of large language models (LLMs), yet maintaining performance in the ultra-low-bit regime remains challenging.
