# Model mirror — sources and licences

Mirror of the model weights the line-extraction tool uses, kept so it keeps working if an upstream file is
removed. Nothing here is ours: every file is redistributed unchanged under its original licence,
which sits next to it. Verify a file with `shasum -a 256`.

`controlnet_aux` network definitions (Apache-2.0, `controlnet_aux/LICENSE`), TEED `ted.py` (MIT),
mflux (MIT, `mflux/LICENSE`).
