# SimpleVQA


## Overview

SimpleVQA is the first comprehensive multimodal benchmark to evaluate the factuality ability of MLLMs to answer natural language short questions. It features high-quality, challenging queries with static and timeless reference answers.

## Task Description

- **Task Type**: Factual Visual Question Answering
- **Input**: Image + factual question
- **Output**: Short factual answer
- **Domains**: Factuality, visual reasoning, knowledge recall

## Key Features

- Covers multiple tasks and scenarios
- High-quality, challenging questions
- Static and timeless reference answers (no temporal dependencies)
- Straightforward evaluation methodology
- Tests genuine factual knowledge beyond pattern matching

## Evaluation Notes

- Default evaluation uses the **test** split
- Primary metric: **Accuracy** with LLM judge
- Three-grade evaluation: CORRECT, INCORRECT, NOT_ATTEMPTED
- LLM judge uses detailed grading rubric for semantic matching
- Rich metadata includes language, source, and atomic facts

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets simple_vqa \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['simple_vqa'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
