What is LibreYOLO?

LibreYOLO is an MIT-licensed computer vision library with inference and training support for a variety of models. It provides a familiar high-level Python and CLI interface and reads common YOLO-format datasets, so existing workflows port over with minimal changes. There is no AGPL anywhere in the dependency chain, so you can use it in closed-source or commercial products.

from libreyolo import LibreYOLO, SAMPLE_IMAGE

model = LibreYOLO("LibreYOLO9t.pt")
result = model(SAMPLE_IMAGE, save=True)

The flagship families are YOLOv9 (CNN) and RF-DETR (transformer) for detection and segmentation. The weights hosted in this organization auto-download on first use.
