Local auto-labeling
It can run local inference with Ultralytics detection models exported to ONNX, including YOLOv5, YOLOv8, YOLO11, YOLO12, and YOLOv26.github.com · 30 Sept 2026
Batch labeling
With a loaded ONNX model, users can auto-label the current image or batch-process all images in the dataset.github.com · 30 Sept 2026
