FALQON: Accelerating LoRA Fine-tuning with Low-Bit Floating-Point Arithmetic

arXiv — cs.LGWednesday, October 29, 2025 at 4:00:00 AM
The recent study on FALQON highlights the benefits of low-bit floating-point formats like FP8 in accelerating model training and saving memory. This is particularly relevant as modern GPUs and NPUs support these formats natively. However, the analysis reveals that while FP8 quantization can enhance performance for large-dimensional matrix multiplications, it may not be as effective for low-rank adaptation (LoRA) due to inherent quantization overheads. Understanding these nuances is crucial for researchers and developers looking to optimize machine learning models.
