+# Ming-Image-0.1-Design INT4 ConvRot
+
+Repackaged model files for ComfyUI and others, with INT4 ConvRot converted for
+testing in Radiant Canvas for fast macOS inference:
+[Radiant Canvas on the App Store](https://apps.apple.com/us/app/radiant-canvas-ai-image-gen/id6802973075).
+
+The original model is
+[inclusionAI/Ming-Image-0.1-Design](https://huggingface.co/inclusionAI/Ming-Image-0.1-Design).
+
+## File
+
+- `ming_image_0.1_design_int4_convrot.safetensors`: the diffusion transformer
+  in ComfyUI's native ConvRot W4A4 format.
+
+For ComfyUI, place the file in:
+
+```text
+ComfyUI/models/diffusion_models/
+```
+
+Use a recent ComfyUI build with Ming-Image and native INT4 ConvRot support. The
+text model, connector, MLP, and VAE are not included in this repository. Use
+the original model files or another compatible ComfyUI package for those
+components.
+
+## Conversion details
