UFO² is rigorously benchmarked on two publicly‑available live‑task suites:
| Benchmark | Scope |
|---|---|
| Windows Agent Arena (WAA) | 154 real Windows tasks across 15 applications (Office, Edge, File Explorer, VS Code, …) |
| OSWorld (Windows) | 49 cross‑application tasks that mix Office 365, browser and system utilities |
The integration of these benchmarks into UFO² is in separate repositories. Please follow the above documents for more details.
!!!note we have revised the verification scripts of some cases to ensure the correctness of the results.
