BitsFusion: 1.99 bits Weight Quantization of Diffusion Model Y ang Sui 1,2, Y anyu Li

Diffusion-based image generation models have achieved great success in recent years by showing the capability of synthesizing high-quality content. However, these models contain a huge number of parameters, resulting in a significantly large model size. Saving and transferring them is a major bottleneck for various applications, especially those running on resource-constrained devices.
