arXiv:2606.09927v1 Announce Type: cross Abstract: Post-training quantization (PTQ) is one of the most practical ways to reduce the serving cost of Large Language Models (LLMs), but activation quantization remains difficult because outlier-dominated channels lead to large quantization errors. This paper investigates whether part of this degradation is caused by over-migration in scaling-based equivalent transformations. We introduce a quantile-robust scaling policy for SmoothRot-style transforms by replacing max-based activation statistics with high quantiles, and we complement it with constrai
The continuous growth in LLM scale demands more efficient deployment, making post-training quantization research increasingly critical to manage serving costs and energy footprints.
This research addresses a core challenge in LLM deployment—reducing model size and computational demands without significant performance degradation, which directly impacts the accessibility and cost-effectiveness of advanced AI.
Improved quantization techniques will make deploying large language models more practical and less resource-intensive, potentially broadening their application across various industries and devices.
