Quick Start (Apple Silicon)

1. Installation

pip install -U mflux

2. CLI Generation

mflux-generate-qwen \
  --model SirSahOl/Qwen-Image-mlx-16bit \
  --prompt "A cinematic portrait of a robotic artisan crafting glass in a neon workshop, 8k, photorealistic" \
  --steps 25 \
  --seed 42

3. Python API

from mflux import QwenImagePipeline

pipeline = QwenImagePipeline.from_pretrained("SirSahOl/Qwen-Image-mlx-16bit")
image = pipeline.generate(
    prompt="A serene mountain lake at sunrise with golden mist, ultra realistic",
    num_inference_steps=25,
)
image.save("output.png")

Architectural Note

These weights represent the 60-block transformer topology (Qwen/Qwen-Image-2512 base) supported by mflux. Native 32-layer Qwen-Image-2.1 weights will be released once upstream mflux merges support for the newly announced 32-layer architecture.
