# C-MMLU
## Overview
C-MMLU (Chinese Massive Multitask Language Understanding) is a comprehensive Chinese evaluation benchmark covering 67 subjects across STEM, humanities, social sciences, and China-specific topics. It evaluates models' knowledge and reasoning in Chinese contexts.
## Task Description
- **Task Type**: Multiple-Choice Question Answering (Chinese)
- **Input**: Chinese question with four answer choices (A, B, C, D)
- **Output**: Single correct answer letter
- **Subjects**: 67 subjects organized into categories including China-specific topics
## Key Features
- 67 subjects covering diverse Chinese knowledge domains
- Includes China-specific topics (Chinese history, literature, civil service exam, etc.)
- Questions from elementary to professional levels
- Tests both general knowledge and China-specific cultural knowledge
- Standard benchmark for Chinese language model evaluation
## Evaluation Notes
- Default configuration uses **0-shot** evaluation
- Uses Chinese Chain-of-Thought (CoT) prompting template
- Results can be aggregated by subject or category
- Categories: STEM, Humanities, Social Science, China-specific, Other
- Evaluates on test split

## Usage
### Using CLI
```bash
evalscope eval \
--model YOUR_MODEL \
--api-url OPENAI_API_COMPAT_URL \
--api-key EMPTY_TOKEN \
--datasets cmmlu \
--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=['cmmlu'],
dataset_args={
'cmmlu': {
# subset_list: ['agronomy', 'anatomy', 'ancient_chinese'] # optional, evaluate specific subsets
}
},
limit=10, # Remove this line for formal evaluation
)
run_task(task_cfg=task_cfg)
```
