# GGUF quantized version of Stable Diffusion 3.5 Medium
## Setup (once)
- drag sd3.5_medium-q5_0.gguf ([2.02GB](https://huggingface.co/calcuis/sd3.5-medium-gguf/blob/main/sd3.5_medium-q5_0.gguf)) to > ./ComfyUI/models/unet
- drag clip_g.safetensors ([1.39GB](https://huggingface.co/calcuis/sd3.5-medium-gguf/blob/main/clip_g.safetensors)) to > ./ComfyUI/models/clip
- drag clip_l.safetensors ([246MB](https://huggingface.co/calcuis/sd3.5-medium-gguf/blob/main/clip_l.safetensors)) to > ./ComfyUI/models/clip
- drag t5xxl_fp8_e4m3fn.safetensors ([4.89GB](https://huggingface.co/calcuis/sd3.5-medium-gguf/blob/main/t5xxl_fp8_e4m3fn.safetensors)) to > ./ComfyUI/models/clip
- drag diffusion_pytorch_model.safetensors ([168MB](https://huggingface.co/calcuis/sd3.5-medium-gguf/blob/main/diffusion_pytorch_model.safetensors)) 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](https://github.com/calcuis/comfy/blob/main/workflow-sd3.5m-gguf.json) (if it doesn't work, upgrade your pack: ggc y) 👻
- example workflow for the original [safetensors](https://github.com/calcuis/comfy/blob/main/workflow-sd3.5m-safetensors.json) 🎃
### Bug reports (or brief review)
- t/q1_0 and t/q2_0; doesn't work; encountering np.uint32(34 & 35) is not a valid GGMLQuantizationType error
- q2_k is super fast; but looks like x-ray film; might be good for medical research or abstract stylist
- q3 family is fast; finger issue can be easily detected but picture quality is interestingly good
- notice the same file size in 0 and s models; still keep them all here; see who can deal with it
- q4 and above should be no problem for general to high quality production
### Upper tier sets
- sd3.5-[large](https://huggingface.co/calcuis/sd3.5-large-gguf) (recommended)
- sd3.5-[turbo](https://huggingface.co/calcuis/sd3.5-large-turbo)
