|
|
## **setup (once)** |
|
- drag pixart-xl-2-1024-ms-q4_k_m.gguf [[1GB](https://huggingface.co/calcuis/pixart/blob/main/pixart-xl-2-1024-ms-q4_k_m.gguf)] to > ./ComfyUI/models/diffusion_models |
|
- drag t5xxl_fp16-q4_0.gguf [[2.9GB](https://huggingface.co/calcuis/pixart/blob/main/t5xxl_fp16-q4_0.gguf)] to > ./ComfyUI/models/text_encoders |
|
- drag pixart_vae_fp8_e4m3fn.safetensors [[83.7MB](https://huggingface.co/calcuis/pixart/blob/main/pixart_vae_fp8_e4m3fn.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-node [pack](https://github.com/calcuis/gguf/releases) below) |
|
- drag the workflow json file (below) or the demo picture above to > your browser |
|
|
|
### **workflow** |
|
- example workflow for [gguf](https://huggingface.co/calcuis/pixart/blob/main/workflow-pixart-gguf.json) |
|
- example workflow for [safetensors](https://huggingface.co/calcuis/pixart/blob/main/workflow-pixart-safetensors.json) |
|
|
|
### review |
|
- should set the output image size according to the model stated, i.e., 1024x1024 or 512x512 |
|
- pixart-xl-2-1024-ms and pixart-sigma-xl-2-1024-ms are recommended (with 1024x1024 size) |
|
- small size model but good quality pictures; and t5 encoder allows you inputting short description or sentence instead of tag(s) |
|
- more quantized versions of t5xxl encoder can be found [here](https://huggingface.co/chatpig/t5xxl/tree/main) |
|
- upgrade your gguf-node (see the last item in reference list below) to the latest version for pixart model support |
