Med2026/Med_eval_data

Med Eval Data

This dataset contains evaluation data for the Med project. Its data format is the same as Med2026/Med_training_data, and it can be loaded with the same codebase from 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.

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

• 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:
