# GPQA-Diamond


## Overview

GPQA (Graduate-Level Google-Proof Q&A) Diamond is a challenging benchmark of 198 multiple-choice questions written by domain experts in biology, physics, and chemistry. The questions are designed to be extremely difficult, requiring PhD-level expertise to answer correctly.

## Task Description

- **Task Type**: Expert-Level Multiple-Choice Q&A
- **Input**: Graduate-level science question with 4 choices
- **Output**: Single correct answer letter (A, B, C, or D)
- **Domains**: Biology, Physics, Chemistry

## Key Features

- 198 questions written and validated by domain PhD experts
- Questions are "Google-proof" - cannot be easily looked up
- Designed to test deep domain knowledge and reasoning
- Diamond subset represents the highest quality questions
- Average human expert accuracy ~65%, non-expert ~34%

## Evaluation Notes

- Default configuration uses **0-shot** or **5-shot** evaluation
- Supports Chain-of-Thought (CoT) prompting for improved reasoning
- Answer choices are randomly shuffled during evaluation
- Only uses train split (validation set is private)
- Challenging benchmark for measuring expert-level reasoning

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets gpqa_diamond \
    --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=['gpqa_diamond'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
