# DDColor FP16 ONNX for WaveSpeed Desktop

This repository hosts a DDColor FP16 ONNX model artifact used by WaveSpeed Desktop's local Image Colorizer free tool.

DDColor is an image colorization model released under the Apache-2.0 license. This repository is intended to provide a stable, public, browser-downloadable model artifact for local inference in WaveSpeed Desktop.

## Files

- `ddcolor-fp16.onnx`: FP16 ONNX model used for local image colorization.
- `ddcolor-fp16.onnx.sha256`: SHA256 checksum for the ONNX file.
- `ddcolor-fp16.provenance.json`: Basic provenance metadata for this hosted artifact.
- `LICENSE-DDColor-Apache-2.0.txt`: Apache-2.0 license notice for DDColor.
- `qualcomm-ddcolor-release_assets.json`: Reference metadata for the Qualcomm DDColor release assets.

## Hosted Artifact

- Repository: https://huggingface.co/wavespeed/image-colorizer
- Model file: https://huggingface.co/wavespeed/image-colorizer/resolve/main/ddcolor-fp16.onnx

## Attribution

This model artifact is based on DDColor.

- Original project: https://github.com/piddnad/DDColor
- License: Apache-2.0

WaveSpeed does not claim authorship of DDColor. This repository hosts the model artifact for use in WaveSpeed Desktop.

## Notes

The current WaveSpeed Desktop Image Colorizer worker loads a single ONNX file as an `ArrayBuffer`.

The official Qualcomm DDColor ONNX release is distributed as a zip with external data files, so it is not a drop-in replacement for the current single-file loader without additional loader support.
