Recommended 4 to 8 steps. Photorealistic images work better with 8 steps while artsy images benefit from lower steps. If textures like skin look overworked, try lowering steps.

⚠️ IMPORTANT

Using BNB NF4/FP4 & GGUF Q4/Q5/Q8 in ComfyUI requires installing custom nodes that add corresponding model loader :

• UNET GGUF: https://github.com/city96/ComfyUI-GGUF

• AIO BNB: https://github.com/comfyanonymous/ComfyUI_bitsandbytes_NF4

• UNET BNB: https://github.com/DenkingOfficial/ComfyUI_UNet_bitsandbytes_NF4

For using UNET versions, you also need to have the TEXT ENCODERS and VAE.

If you don't have them, download them from here:

• TEXT ENCODERS: https://huggingface.co/comfyanonymous/flux_text_encoders/tree/main

• VAE: https://huggingface.co/black-forest-labs/FLUX.1-schnell/tree/main/vae

Place the model in "models/unet", both text encoders in "models/clip" and vae in "models/vae" folder.

In ComfyUI, use the standard flux workflow or add 'Load Diffusion Model', 'DualClipLoader' and 'Load VAE' nodes to replace the checkpoint loader and complete the setup.

In Forge, set the option "Diffusion in low bits" to "bnb-nf4"
