[Also on CivitAI](https://civitai.com/models/630820)

Merge of Schnell and Dev variants of the Flux.1 model, almost all block are set to different ratios so it's not a perfect proportion of each model.

Recommended 4-8 steps.

# Important

**All in one versions** include VAE + CLIP + T5XXL (fp8). 

**UNET versions** (Model only) need Text Encoders and VAE, downloads:
- Text Encoders: https://huggingface.co/comfyanonymous/flux_text_encoders/tree/main
- VAE: https://huggingface.co/black-forest-labs/FLUX.1-schnell/tree/main/vae

**GGUF versions (Q4, Q5, Q8)** require a custom node to work in comfy: https://github.com/city96/ComfyUI-GGUF

**BNB versions (NF4, FP4)** require a custom node to work in comfy:

- All in one versions: https://github.com/comfyanonymous/ComfyUI_bitsandbytes_NF4
- UNET versions: https://github.com/DenkingOfficial/ComfyUI_UNet_bitsandbytes_NF4
