Copyright (c) 2026 CoreYOLO contributors.

CoreYOLO is licensed under the MIT License (see LICENSE).

NOTE ON WEIGHTS: No pretrained weight files are shipped with this source
repository. Published CoreYOLO checkpoints live separately (GitHub Releases)
and carry their own per-file licenses, reflecting each upstream. Those
licenses vary and are not all permissive: some published YOLOv9 dumps are
AGPL-3.0, and this MIT License does not extend to them. Choosing a model
means choosing its license. See weights/LICENSE_NOTICE.txt and
docs/licenses.md for the terms on each source.

NOTE ON THIRD-PARTY CODE: CoreYOLO does not vendor another detector's
trainer source. Optional `coreyolo convert` remaps tensor names from a
checkpoint you already have; converting a file does not change its
applicable terms. The numbers keep the license of whoever trained them.

YOLOv9 GELAN (MultimediaTechLab/YOLO) — MIT
 Source: https://github.com/MultimediaTechLab/YOLO
 Release: v1.0-alpha files v9-t.pt, v9-s.pt, v9-m.pt, v9-c.pt
 Copyright (c) 2024 Kin-Yiu Wong and Hao-Tang Tsui
 The authors' MIT re-release, not WongKinYiu/yolov9 (GPL-3.0).
 Converted CoreYOLO zoo rows (coreyolo-n/s/m/l-coco) keep MIT and
 this copyright notice. Same source LibreYOLO uses for LibreYOLO9{t,s,m,c}.

YOLOv9 (Ultralytics yolov9t/s/m/c.pt) — AGPL-3.0
 Those files are a different dump. Converted checkpoints inherit
 AGPL-3.0. They are not covered by CoreYOLO's MIT License.

Weights you train from scratch on CoreYOLO — MIT
 The code is permissive, so a model you train yourself on data you
 have the right to use is yours. The pretrained checkpoint's terms
 never enter it.
