## 👁️ Overview

**GSM8K-V** is a purely visual multi-image mathematical reasoning benchmark that systematically maps each GSM8K math word problem into its visual counterpart to enable a clean, within-item comparison across modalities. Built via an automated pipeline that extracts and allocates problem information across scenes, generates scene-level descriptions, and renders images, coupled with meticulous human annotation, the benchmark comprises 1,319 high-quality multiscene problems (5,343 images) and addresses limitations of prior visual math evaluations that predominantly focus on geometry, seldom cover visualized word problems, and rarely test reasoning across multiple images with semantic dependencies. Evaluations of a broad range of open- and closed-source models reveal a substantial modality gap—for example, Gemini-2.5-Pro attains 95.22% accuracy on text-based GSM8K but only 46.93% on GSM8K-V—highlighting persistent challenges in understanding and reasoning over images in realistic scenarios and providing a foundation to guide the development of more robust and generalizable vision-language models.

## 🚀 Quick Start

```bash
