# 🎯 SPAR-Bench-Tiny

> A lightweight subset of SPAR-Bench for **fast evaluation** of spatial reasoning in vision-language models (VLMs).

**SPAR-Bench-Tiny** contains **1,000 manually verified QA pairs** — 50 samples per task across **20 spatial tasks** — covering single-view and multi-view inputs. 

This dataset mirrors the structure and annotation of the full [SPAR-Bench](https://huggingface.co/datasets/jasonzhango/SPAR-Bench), but is **10× smaller**, making it ideal for low-latency evaluation.



## 📥 Load with `datasets`

```python
from datasets import load_dataset
spar_tiny = load_dataset("jasonzhango/SPAR-Bench-Tiny")
```
## 🕹️ Evaluation

SPAR-Bench-Tiny uses the **same evaluation protocol and metrics** as the full [SPAR-Bench](https://huggingface.co/datasets/jasonzhango/SPAR-Bench).

We provide an **evaluation pipeline** in our [GitHub repository](https://github.com/hutchinsonian/spar), built on top of [lmms-eval](https://github.com/EvolvingLMMs-Lab/lmms-eval).
