arXiv:2605.24144v1 Announce Type: cross Abstract: Large Language Models (LLMs) have achieved impressive performance across diverse domains but remain inefficient during the autoregressive decoding phase. Unlike the prefill stage, which employs compute-bound GEMM operations, decoding executes a sequence of small GEMV-like computations that are memory-bound and underutilize modern accelerators. Weight-only vector quantization (VQ) has emerged as an effective compression technique that clusters model weights into a shared codebook and replaces the original weight matrix with low-precision indices
The paper addresses a critical current bottleneck in LLM deployment, moving beyond training efficiency to tackle the very practical problem of efficient inference on existing hardware.
This development could significantly reduce the operational costs and hardware requirements for deploying large language models, making advanced AI more accessible and scalable.
The efficiency of LLM decoding, particularly the memory-bound GEMV operations, can be substantially improved, leading to faster inference and lower computational resource demands per query.
