Stable Diffusion 3.5 Large (GGUF)

GGUF Quants of the new Stable Diffusion 3.5 Large model.

Pardon my image samples, I'm on a mac so diffuse'ing sd3 takes a while, so I didn't do much tweaking or many steps, but I'm gonna update them to be all the same seed/size and workflow to compare at least.

Thanks to city96 for all his hard work for the conversion utility work an getting things working with me on his github, all the thanks in the world to him for the incredible help.

Stable Diffusion 3.5 Large is a Multimodal Diffusion Transformer (MMDiT) text-to-image model that features improved performance in image quality, typography, complex prompt understanding, and resource-efficiency.
