Core ML conversions used by a photo-editing **prototype** (research spike, MIXME-408).
Downloaded on demand by the app; not part of any shipping product.

| Model | Task | Size | Input | Output | Source & licence |
|---|---|---|---|---|---|
| `DDColorTiny.mlpackage` | B&W photo colorization | ~116 MB | 512×512 RGB image (gray rendered from L) | `ab` tensor (1×2×512×512) | [DDColor](https://github.com/piddnad/DDColor) (`ddcolor_paper_tiny`), Apache-2.0 |
| `RealESRGANx2.mlpackage` | 2× super-resolution | ~33 MB | 512×512 RGB tile | 1024×1024 RGB image | [Real-ESRGAN](https://github.com/xinntao/Real-ESRGAN) (`RealESRGAN_x2plus`), BSD-3-Clause |

Both converted with coremltools (fp16 mlprogram, iOS 17 minimum target) from the
authors' official released weights, and parity-checked against the PyTorch originals.
