sc-layout-models
ONNX exports of Armaggheddon/yolo26-document-layout
(MIT), used as the default layout detector by sc_toolkit's hybrid PDF parser.
Exported with tools/export_layout_onnx.py from the sc_toolkit repo:
imgsz=1280, opset=17, simplified, names class metadata embedded. Served
through onnxruntime (MIT); ultralytics is used at export time only and is
not required to run these files.
| file | variant | size |
|---|---|---|
yolo26m_doc_layout.onnx |
m — the sc_toolkit default | ~82 MB |
yolo26n_doc_layout.onnx |
n — the cheap option (HYBRID_LAYOUT_MODEL=superchaintech/sc-layout-models#yolo26n_doc_layout.onnx) |
~10 MB |
Known deviation from the source weights (measured, sc_toolkit repo,
docs/layout-model-comparison-2026-08.md): the ONNX decode agrees with the
ultralytics runtime on ~98% of regions at IoU≥0.5 and can differ on the rest.
