High-accuracy Low-Bit KV-Cache Quantization via Local Distribution Restoration

Gradwell Dzikanyanga, Yanqi Pan, Weihao Yang, Donglei Wu, Wen Xia, Hao Huang

Long-context large language model inference relies on the KV cache to avoid redundant attention computation, but incurs high memory and bandwidth overheads. Low-bit KV-cache quantization reduces this cost, yet it severely degrade quality; particularly, one-bit quantization reduce…Read more
