## Quick start

```bash
uv venv --python 3.13
source .venv/bin/activate

uv pip install "mlx-reason-ct==0.3.6"
uv tool install huggingface-hub

hf download MedMLX/MLX-Reason-CT --revision 5e5b5202fd04ac9f63ede203ebc9327aa676ae94 --local-dir models
```

Replace the example input paths with your own files.

```bash
mlx-reason-ct report \
  --input ct.nii.gz --model-dir models --output-dir outputs
```

Requires `mlx-reason-ct`; generic `mlx-vlm` and `mlx-lm` loaders are incompatible. Allow more than 22.7 GB unified memory for the model, preprocessing and macOS.
