## Overview

General-VMCQ is a customizable visual multiple-choice question answering benchmark for multimodal models.
It uses MMMU-style format with image/video placeholders in text, supporting flexible media inputs.

## Task Description

- **Task Type**: Visual Multiple-Choice Question Answering
- **Input**: Question with `<image N>`/`<video N>` placeholders + choice options + media
- **Output**: Selected answer choice
- **Flexibility**: Supports custom datasets via local files

## Key Features

- MMMU-style format (not OpenAI message format)
- Supports up to 100 images and 100 videos per sample
- Flexible image/video input (path, URL, or base64 data URL)
- Chain-of-thought prompt template option
- Custom dataset support via local file loading

## Evaluation Notes

- Default configuration uses **0-shot** evaluation
- Primary metric: **Accuracy**
- Train split: **dev**, Eval split: **val**
- Images/videos are plain strings (do not wrap in `{{"url": ...}}`)
- See [User Guide](https://evalscope.readthedocs.io/en/latest/advanced_guides/custom_dataset/vlm.html) for dataset format

    --datasets general_vmcq \
    --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=['general_vmcq'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
