# Med Eval Data

This dataset contains evaluation data for the **Med** project. Its data format is the same as [`Med2026/Med_training_data`](https://huggingface.co/datasets/Med2026/Med_training_data), and it can be loaded with the same codebase from [`GAIR-NLP/Med`](https://github.com/GAIR-NLP/Med).

## Overview

Each example is stored in the same JSON / parquet schema as the training data, with the following top-level fields:

- `images`
- `data_source`
- `prompt`
- `ability`
- `reward_model`
- `extra_info`
- `agent_name`

This means the dataset is directly compatible with the data loading pipeline used in the Med codebase.

## Compatibility

This dataset has the **same format** as [`Med2026/Med_training_data`](https://huggingface.co/datasets/Med2026/Med_training_data).

You can use the same loading logic and preprocessing pipeline from:

- [`GAIR-NLP/Med`](https://github.com/GAIR-NLP/Med)

No format conversion is required.

## Data Split by File Naming

The evaluation data is divided into two settings according to the file name:

- Files with `single_turn_agent` in the filename correspond to **evaluation without tool use**
- Files with `tool_agent` in the filename correspond to **evaluation with tool use**

In other words:

- `*single_turn_agent*` → without-tool evaluation
- `*tool_agent*` → with-tool evaluation

## Data Format

Each sample is a JSON object with the following structure:

```python

  "prompt": [
