FLUX.1-schnell-Quantized

How to:

1. Dowload and build stable-diffusion.cpp
2. Download one of the models from this repo and
   • Autoencoder https://huggingface.co/black-forest-labs/FLUX.1-schnell/resolve/main/ae.safetensors
   • CLIP_L https://huggingface.co/comfyanonymous/flux_text_encoders/blob/main/clip_l.safetensors
   • T5XXL https://huggingface.co/comfyanonymous/flux_text_encoders/blob/main/t5xxl_fp16.safetensors
3. Enter your stable-diffusion.cpp dir
4. Run the following command:
   ./build/bin/sd --diffusion-model [path to gguf] --vae [path to ae.safetensors] --clip_l [path to clip_l.safetensors] --t5xxl [path to t5xxl_fp16.safetensors] -p "a frog holding a sign saying 'hi' " -o ../frog.png -v --cfg-scale 1.0 --sampling-method euler -v --seed 42 --steps 4
