GGUF quantized version of Stable Diffusion 3.5 Medium Setup (once) drag sd3.5 medium q5 0.gguf (2.02GB) to ./ComfyUI/models/unet drag clip g.safetensors (1.39GB) to ./ComfyUI/models/clip drag clip l.safetensors (246MB) to ./ComfyUI/models/clip drag t5xxl fp8 e4m3fn.safetensors (4.89GB) to ./ComfyUI/models/clip drag diffusion pytorch model.safetensors (168MB) to ./ComfyUI/models/vae Run it straight (no installation needed way) run the .bat file in the main directory (assuming you are using the gguf comfy pack below) drag the workflow json file (see below) to your browser generate your first picture with sd3, awesome! Workflows example workflow for gguf (if it doesn't work, upgrade your pack: ggc y) 👻 example workflow for the original safetensors 🎃 Bug reports (or brief review) t/q1 0 and t/q2 0; not working recently (invalid GGMLQ type error) q2 k is super fast; not usable; but might be good for medical research or abstract painter q3 family is fast; finger issue can be easily detected but picture quality is interestingly good btw, q3 family is usable; just need some effort on +/ prompt(s); good for old machine user notice the same file size in some quantized models; but they are…
