OptRot: Data-Free Rotations Improve LLM Quantization

Published:Dec 30, 2025 10:13
1 min read
ArXiv

Analysis

This paper addresses the challenge of quantizing Large Language Models (LLMs) by introducing a novel method, OptRot, that uses data-free rotations to mitigate weight outliers. This is significant because weight outliers hinder quantization, and efficient quantization is crucial for deploying LLMs on resource-constrained devices. The paper's focus on a data-free approach is particularly noteworthy, as it reduces computational overhead compared to data-dependent methods. The results demonstrate that OptRot outperforms existing methods like Hadamard rotations and more complex data-dependent techniques, especially for weight quantization. The exploration of both data-free and data-dependent variants (OptRot+) provides a nuanced understanding of the trade-offs involved in optimizing for both weight and activation quantization.
