camstack/camstack-models

CamStack model mirror

This repository is a mirror of third-party models converted by CamStack into the formats its inference engines run (ONNX, OpenVINO IR, CoreML). Nothing here is relicensed. Each folder stays under the licence of the model it was made from, stated in the folder's README.md and in the table below, with the full text in LICENSES/. The repository as a whole has no single licence; see LICENSE.

Every model file here is a modified version of its upstream: at minimum converted to another format; where the folder card says so, re-exported at a smaller input size, quantised (OpenVINO NNCF INT8), fine-tuned, or with a graph edit.

THIRD_PARTY_MODELS.md is the notice CamStack ships with its software. It covers every model CamStack can download, including those fetched from other repositories, with the attributions each licence requires.

AGPL-3.0 models (Ultralytics)

objectDetection/yolo26, objectDetection/yolov9 and segmentation/yolo26-seg hold Ultralytics weights under AGPL-3.0 (LICENSES/AGPL-3.0.txt). Their Corresponding Source is set out in Source offer for the AGPL-3.0 weights.

Non-commercial models

This may not be used commercially. See the folder's card.

Models

"Unknown" means no licence could be traced; it does not mean free to use. default marks the model a CamStack step runs when nobody chose one; hidden marks an entry kept resolvable for a saved selection but no longer offered.

This mirror holds only the models CamStack offers. Models it no longer offers (SCRFD, ArcFace, Inception-ResNet, VGG-English, MobileCLIP S1/S2, YOLOv8n-package, SSDLite MobileDet, the YOLOv8n plate detector, and earlier a third-party face, PaddleOCR, animals-10, NABirds and EfficientNet folders) were removed, and the repository history was squashed on 2026-10-06.
