YOLO26M Question Segmentation

Larger release checkpoint with stronger localization than the older public YOLO11m baseline.

• Task: object detection
• Classes: question
• Input size: 1280
• Base model: yolo26m

Intended use

This model is designed to detect question regions in exam booklets, worksheets, and PDF page renders. It works best on dense educational pages with clear question boundaries.

Release notes

This release checkpoint is a cleaned fine-tune of a previously trained YOLO26M run, finalized without mosaic augmentation.

Test results

Old held-out test set

Combined held-out test set

Usage

from ultralytics import YOLO

model = YOLO("hf://samil24/yolo26m-question-segmentation")
results = model("page.png", imgsz=1280, conf=0.25)
