yolo26n-seg (ONNX)
The official Ultralytics YOLO26n-seg COCO weights (yolo26n-seg.pt), exported unchanged to ONNX so they can run in the
browser with onnxruntime-web. Not fine-tuned.
| Input | images — float32 [1, 3, 640, 640], RGB 0–1, letterboxed (pad 114) |
| Output 0 | [1, 116, 8400] = box cx, cy, w, h + 80 class scores + 32 mask coefficients. NMS is not included |
| Output 1 | [1, 32, 160, 160] mask prototypes — mask = sigmoid(coefficients · prototypes), cropped to the box |
| Size | ONNX 11.2 MB (opset 17, simplified) · source .pt 6.7 MB |
| Classes | COCO 80 |
