+# SAT-v2 Dataset
+
+## Paper
+
+**SAT: Dynamic Spatial Aptitude Training for Multimodal Language Models**
+
+This dataset is part of the SAT (Spatial Aptitude Training) project, which introduces a dynamic benchmark for evaluating and improving spatial reasoning capabilities in multimodal language models.
+
+- **Project Page**: [https://arijitray.com/SAT/](https://arijitray.com/SAT/)
+- **Paper**: [arXiv:2412.07755](https://arxiv.org/abs/2412.07755)
+
+## Dataset Description
+
+SAT-v2 is a comprehensive spatial reasoning benchmark containing over 300,000 questions across multiple splits. The dataset tests various aspects of spatial understanding including perspective-taking, object relationships, and dynamic scene understanding.
+
+## Loading the Dataset
+
+```python
+from datasets import load_dataset
+
+# Load the training split
+dataset = load_dataset("array/SAT-v2", split="train")
+
+# Or load a specific split
+val_dataset = load_dataset("array/SAT-v2", split="val")
+static_dataset = load_dataset("array/SAT-v2", split="static")
+test_dataset = load_dataset("array/SAT-v2", split="test")
+
+# Access a sample
+sample = dataset[0]
+print(sample["question"])
+print(sample["answers"])
+print(sample["correct_answer"])
+```
+
+## Dataset Splits
+
+- **train**: 172,384 examples - Dynamic training questions
+- **static**: 127,405 examples - Static spatial reasoning questions
+- **val**: 4,001 examples - Validation set
+- **test**: 150 examples - Test set
+
+**Important Note on Test Set Evaluation:** When evaluating on the test set, please use circular evaluation by switching the position of the correct answer to avoid position bias. If you're using lmms-eval, refer to the implementation here: [https://github.com/arijitray1993/lmms-eval/tree/main/lmms_eval/tasks/sat_real](https://github.com/arijitray1993/lmms-eval/tree/main/lmms_eval/tasks/sat_real)
