arXiv:2606.15652v1 Announce Type: cross Abstract: 4-bit quantization significantly reduces the memory footprint and accelerates the inference of large language models (LLMs). However, its limited bit-width representation struggles to faithfully capture both dense common values (\emph{inliers}) and rare large-magnitude values (\emph{outliers}), causing substantial accuracy degradation. Existing mixed-precision methods mitigate this by retaining outliers in high precision, but at the cost of breaking the uniformity of low-bit execution, introducing precision conversion and extra data movement th
The rapid growth of Large Language Models (LLMs) is creating immense pressure for more efficient deployment, driving innovation in quantization techniques to balance performance and resource demands.
Efficient 4-bit quantization allows for wider deployment of powerful LLMs on resource-constrained devices, democratizing access and expanding AI application frontiers.
Previously challenging trade-offs between 4-bit quantization accuracy and computational uniformity are being addressed, potentially standardizing efficient LLM inference.
