Model Registry

OpenDetect ships a built-in model registry. Each model entry defines:

• model_id

• implementation family (rfdetr, yolox, rtmdet, or bytetrack)

• default input size

• remote artifact path

• aliases and description

Included Families

Family	Year	License	Why included
RF-DETR	2026	Apache-2.0	Strong modern accuracy/speed tradeoff
ByteTrack Detector	2022	MIT	ByteTrack MOT17 detector for accurate but slow detection
RTMDet	2022	Apache-2.0	Strong real-time detector baseline from MMDetection
YOLOX	2021	Apache-2.0	Stable last Apache-2.0 YOLO-family baseline

Inspect and Download

CLI:

opendetect-models list
opendetect-models info rfdetr-m
opendetect-models download rfdetr-m

Python:

from opendetect import list_models, get_model_spec

print([spec.model_id for spec in list_models()])
print(get_model_spec("rfdetr-m"))

Caching

Default cache path:

• ~/.cache/opendetect/checkpoints

Override with:

• OPENDETECT_CACHE_DIR

You can also override the registry base URL with:

• OPENDETECT_MODEL_BASE_URL
