Large diffusion models like Flux can generate impressive images but require substantial memory, making quantization an attractive option to reduce their size without significantly affecting output quality. The article discusses various quantization backends available in Hugging Face Diffusers, including bitsandbytes, torchao, and Quanto, and provides examples of how to implement these quantizations to optimize memory usage and performance in image generation tasks.

SINQ is a fast and model-agnostic quantization technique that enables the deployment of large language models on GPUs with limited memory while maintaining accuracy. It significantly reduces memory requirements and quantization time, offering improved model quality compared to existing methods. The technique introduces dual scaling to enhance quantization stability, allowing users to quantize models quickly and efficiently.
