Download all necessary model files and move them to the following paths:
From text_encoders folder, the files clip_g.safetensors, clip_l.safetensors, t5xxl_fp16.safetensors, or t5xxl_fp8_e4m3fn.safetensors to the location ComfyUI\models\clip
From transformer folder, the file diffusion_pytorch_model.safetensors to the location ComfyUI\models\unet
From vae folder, the file diffusion_pytorch_model.safetensors to the location ComfyUI\models\vae
While this model can handle long prompts, you may observe artifacts on the edge of generations when T5 tokens go over 256. Pay attention to the token limits when using this model in your workflow, and shortern prompts if artifacts becomes too obvious.
The medium model has a different training data distribution than the large model, so it may not respond to the same prompt similarly.
We recommend sampling with Skip Layer Guidance for better structure and anatomy coherency.
