This Cua-S1 component does not bundle third-party model weights, datasets, binaries, or media.

Parts of python/src/cua_s1/model.py are adapted from the MIT-licensed jevlike project at commit 94f5fd1b0b11d52bbdfdf4e0ee6aa96b568f8452. The adapted material is limited to the byte-collation and small attention-model primitives in that file.

The Python package declares Hatchling as a build-system requirement. Hatchling is build tooling and is not bundled in the resulting package; it is distributed under its own terms.

The Python package declares its runtime dependencies in python/pyproject.toml. The component-local python/uv.lock records the tested development resolution. Those dependencies remain distributed under their own licenses and are not copied into this repository.

Future checkpoint or software distributions must update this file with the applicable notices for all included third-party code, models, datasets, assets, and other materials. A reference to Cua-S1 or cua-s1-form-v0 does not grant rights to third-party material.
