# Halluminate Westworld

A benchmark for web agents to perform tasks on realistic websites.

Repo: https://github.com/Halluminate/westworld

Blog post: https://halluminate.ai/blog/westworld

## Quick Start: Try a Task Yourself

Want to understand what the benchmark tasks look like? You can run them manually using our human-in-the-loop demo:

### Step 1: Install with Browser Support

```bash
# Using uv (recommended)
uv pip install -e ".[datasets,playwright]"
python -m playwright install chromium

# Or using pip
pip install -e ".[datasets,playwright]"
python -m playwright install chromium
```

### Step 2: Set Your API Key (for simulated environments)

```bash
export HALLUMINATE_API_KEY=your-key-here
```
*contact wyatt@halluminate.ai for an api key*

### Step 3: Run the Demo

You can run the demo in two ways:

**Option A: Run by dataset index**
```bash
westworld-demo --index 0
```

**Option B: Run by specific task ID**
```bash
westworld-demo --task-id westworld/azora/basic_checkout/0
```

**Alternative: Run as Python module**
```bash
# By index
python -m westworld.demo --index 0

# By task ID
python -m westworld.demo --task-id westworld/azora/basic_checkout/0
```

## Dataset

The benchmark dataset is available on [HuggingFace](https://huggingface.co/datasets/Halluminate/westworld):

```python
from datasets import load_dataset

dataset = load_dataset("Halluminate/westworld")
```

## Usage

### Loading and Running Tasks

```python
from westworld.base import DatasetItem, instantiate

# Load a task from the dataset
task_item = DatasetItem(**dataset[0])

# Generate the task configuration
task_config = task_item.generate_task_config()

# Access task details
print(f"Task: {task_config.task}")
print(f"URL: {task_config.url}")
print(f"Evaluation Config: {task_config.eval_config}")
```

### Task Categories

The benchmark includes the following task categories (L1 categories):

- **e_commerce**: Online shopping tasks across multiple platforms
  - Basic checkout flows
  - Delivery instruction handling
  - Pickup order management

- **travel**: Travel booking and search tasks
  - Flight searches (basic, roundtrip, date ranges)
  - Airline-specific searches
  - Hotel searches
  - Budget-constrained searches
