arXiv:2605.26189v1 Announce Type: new Abstract: Quantization-aware training (QAT) with low-bit floating-point formats enables efficient LLM deployment, yet introduces subtle failure modes invisible to standard training metrics. We present a systematic study of HiF8 W8A8 QAT for OpenPangu-Embedded-1B through the lens of Delayed Tensor Scaling (DTS). Across eight controlled experiments, we identify and disentangle two orthogonal failure modes: (i)amax saturation, where delayed scale estimates silently corrupt knowledge-sensitive representations via forward-pass clipping, and (ii)catastrophic for
The accelerating demand for efficient AI inference, especially for Large Language Models (LLMs), is driving intense research into quantization techniques to reduce computational and memory footprints.
Improving low-bit floating-point quantization without accuracy loss is crucial for deploying performant LLMs on resource-constrained edge devices and reducing the operational costs of large AI models.
This research provides a methodical approach to mitigate previously unseen failure modes in quantization-aware training, potentially leading to more reliable and efficient hardware-agnostic LLM deployment.
