Converted with MFlux 0.22.0 on 2026-10-09.

Standard MFlux quantization uses MLX affine quantization (6-bit) across the text encoder, transformer and VAE. The quantization level is stored in the weights, so no --quantize flag is needed.

Usage

Install MFlux

uv tool install --upgrade mflux

Generate an image using Fibo-1.5 Q6:

mflux-generate-fibo \
  --model mflux-community/fibo-1-5-mflux-q6 \
  --base-model fibo \
  --prompt "A puffin standing on a cliff" \
  --width 1024 \
  --height 1024 \
  --seed 42 \
  --output image.png

The weights are downloaded from this repo on first use. To keep a local copy instead:

hf download mflux-community/fibo-1-5-mflux-q6 --local-dir ./fibo-1-5-mflux-q6

then pass --model ./fibo-1-5-mflux-q6.
