The record

Purpose: YoloLabel is a GUI for marking object bounding boxes in images to train YOLO neural networks.
Annotation: It supports manual bounding box labeling and uses a two left-click method to create boxes.
Image formats: The README says to load .jpg or .png images from a directory.
Local auto-labeling: It can run local inference with Ultralytics detection models exported to ONNX, including YOLOv5, YOLOv8, YOLO11, YOLO12, and YOLOv26.
Batch labeling: With a loaded ONNX model, users can auto-label the current image or batch-process all images in the dataset.
Cloud integration: YoloLabel integrates with yololabel.com for cloud open-vocabulary object detection, using an API key and optional detection prompt.
Cloud batch limit: Cloud Auto Label All submits images in batches of up to 20 per request.
Image tools: The app includes real-time contrast adjustment and a usage timer that runs while its window is focused.
Download platforms: The README lists prebuilt downloads for Windows x64, Linux x64, and macOS on Apple Silicon.
Build requirement: Building from source with auto-label support requires ONNX Runtime; without it, the app works without that feature.
Usage caveat: The README warns that moving the horizontal image slider does not automatically save the last processed image.
Maker: The maker’s GitHub profile identifies developer0hye as Yonghye Kwon.
Manual annotation: It uses a two-click method to create boxes and includes tools to move, resize, copy, paste, undo, and redo annotations.
Supported models: The README lists YOLOv5, YOLOv8, YOLO11, YOLO12, YOLOv26, and end-to-end ONNX models as supported for auto-labeling.
