Model files (2026-10)

The model files rascal's segmenter pack uses (segment, the remove_prompt recipe): OWLv2 base patch16 for text-prompted detection and SAM 2.1 hiera-tiny for the masks, exported to ONNX (opset 18). Both are Apache-2.0; provenance, revisions and the export's parity checks are in export.json and tools/python/MODEL.md.

rascal tools setup (and rascal-tools fetch) downloads these and checks each against the SHA-256 in tools/python/src/rascal_tools/artifacts.toml; the release bundles carry them under models/.
