# BrowseComp
## Overview
BrowseComp is an OpenAI benchmark for evaluating browsing and search agents. It contains 1,266 hard-to-find, fact-seeking questions with short, verifiable answers. EvalScope loads the mirrored dataset from ModelScope (`evalscope/browse_comp`).
## Task Description
- **Task Type**: Search-agent factual question answering
- **Input**: Challenging natural-language question that generally requires persistent web browsing
- **Output**: Explanation, exact answer, and confidence
- **Grading**: LLM judge compares the final answer against the reference answer
## Key Features
- Tests persistence, creative search, and multi-hop evidence gathering
- Uses short answers to keep grading tractable
- Official data is distributed as encrypted CSV rows and decrypted at evaluation time
- Classified as an Agent benchmark and compatible with EvalScope agent loop modes
- Supports single-turn model evaluation by default and native/external agent execution when `TaskConfig.agent_config` is provided
## Evaluation Notes
- Default evaluation loads `evalscope/browse_comp` from ModelScope through the standard EvalScope dataset loader.
- Use `TaskConfig.agent_config` to evaluate BrowseComp with EvalScope agent loop capabilities such as native tool-use or external agent runners.
- The primary metric is `is_correct`; `is_incorrect` is also reported.
- LLM judge is enabled by default. `JudgeStrategy.RULE` falls back to normalized exact match.

## Usage
### Using CLI
```bash
evalscope eval \
--model YOUR_MODEL \
--api-url OPENAI_API_COMPAT_URL \
--api-key EMPTY_TOKEN \
--datasets browsecomp \
--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=['browsecomp'],
limit=10, # Remove this line for formal evaluation
)
run_task(task_cfg=task_cfg)
```
