| Task | Complete annotation file | Records |
|---|---|---|
| MCQ | annotations/train.mcq.v3.jsonl.gz |
6,850,706 |
| Open-QA | annotations/train.open_qa.jsonl.gz |
385,040 |
| Grounding | annotations/train.grounding.jsonl.gz |

The 47 MCQ part-* files are subsets covering the first 777,413 records of the complete MCQ file. For the full MCQ set, use annotations/train.mcq.v3.jsonl.gz alone.
Each compressed JSONL file contains one training record per line with messages and images.
MCQ and Open-QA records provide a direct image URL or an official dataset download page in images. Records with dataset-page URLs also include path, which locates the image within the extracted dataset. Obtain these images under the original providers' access conditions and replace images with local file paths before training.
Grounding records use image paths relative to the dataset directory. The 428,501 grounding images are included in image_shards/grounding-*.tar.gz. Extract all grounding archives from the dataset directory:
for archive in image_shards/grounding-*.tar.gz; do
tar -xzf "$archive" -C .
done
MCQ includes both ordinary and reasoning responses. Open-QA responses use <think>...</think> and <answer>...</answer>. Grounding responses contain bounding boxes in integer normalized [x1, y1, x2, y2] coordinates, as specified by each prompt.
