What is FP4DiT: Floating Point Quantization for DiTs about?

The document presents FP4DiT, a novel Post-Training Quantization (PTQ) method designed for Diffusion Transformers (DiTs) that utilizes Floating-Point Quantization (FPQ) to improve image generation efficiency without compromising quality. FP4DiT addresses the limitations of existing integer-based quantization methods by aligning weight and activation distributions more effectively, achieving W4A6 and W4A8 precision levels. Experimental results demonstrate that FP4DiT outperforms previous methods in generatin
