# Molmo2-ER · array/SAT
Spatial Aptitude Training: 175K binary-MCQ VQA pairs over ProcTHOR indoor scenes.
This is a re-hosted, **loader-ready subset** of the upstream dataset, used to train [`allenai/Molmo2-ER-4B`](https://huggingface.co/allenai/Molmo2-ER-4B). Files mirror the upstream layout; nothing in the data has been modified.
## Upstream source

- **Paper:** *SAT: Dynamic Spatial Aptitude Training for Multimodal Language Models* ([arXiv:2412.07755](https://arxiv.org/abs/2412.07755))
- **License:** `mit` (inherits from upstream)
