## What this evaluates

This evaluation probes the agentic capabilities of computer-use models by measuring their ability to complete multi-step web browsing and task-completion tasks on live websites. It assesses both functional success rates and operational efficiency, including token usage, cost, and interaction length.

## Datasets

- **WebVoyager** — total ?; splits: test (-1)
- **Online-Mind2Web** — total ?; splits: test (-1)
- **DeepShop** — total ?; splits: test (-1)
- **WebTailBench** — total 609; splits: test (609)
- **ScreenSpot** — total ?; splits: test (-1)

## Metrics

- `success rate` **(primary)** — range: percent
  - The percentage of tasks successfully completed out of the total number of tasks. Calculated by averaging results over three independent runs, with trajectories capped at 100 steps.
- `cost per task` — range: other
  - The average monetary cost in USD required to complete a single task, derived from token pricing and action counts.
- `actions per task` — range: other
  - The average number of low-level browser actions executed by the model to complete a task.

## Input / output format

**Input**: Screenshot of the current browser/UI state paired with the task instruction/prompt.

**Output**: Low-level browser actions (e.g., click, type, scroll) or agent step commands.

## Scoring recipe

```python
def compute_success_rate(tasks, judge_model):
    successful = 0
    for task in tasks:
        trajectory = run_agent(task.prompt, max_steps=100)
        if trajectory.failed_due_to_env_error:
            trajectory = retry_up_to_5_times(trajectory)
        if judge_model.evaluate(trajectory, task.gold_criteria):
            successful += 1
    return (successful / len(tasks)) * 100
# Average over 3 independent runs for final metric.
```

## Common pitfalls

- Live websites change daily, causing high variance; evaluations must be averaged over multiple runs and only retry on environment errors, not incorrect completions.
- Time-sensitive tasks become stale; requires filtering impossible tasks or modifying future dates to current ones to ensure solvability.
- LLM-as-a-judge success rates often overestimate human-verified accuracy due to prompt and model misalignment.

## Evidence (verbatim from paper)

> We evaluate our agent on three popular benchmarks against live websites: WebVoyager, Online Mind2Web, and DeepShop, as well as our WebTailBench. For ascertaining success rate, we retain the same prompts, llm-as-a-judge model type, and procedure published with each benchmark. Namely, we use GPT-4o along with the official respective prompts in the LLM-based judge for WebVoyager and Deepshop, and o4-mini as the LLM-based judge for Online-Mind2Web and WebTailBench.
