# Mobile World: Benchmarking Autonomous Mobile Agents in Agent-User Interactive, and MCP-Augmented Environments
Mobile World is a substantially more challenging mobile-use benchmark designed to better reflect real-world mobile usage. It comprises 201 tasks across 20 applications, featuring long-horizon, cross-app tasks, and novel task categories including agent-user interaction and MCP-augmented tasks.
The difficulty of Mobile World is twofold:
- Long-horizon, cross-application tasks. Mobile World tasks require on average 27.8 completion steps, nearly twice as many as 14.3 steps required in AndroidWorld. Moreover, 62.2% of tasks involve cross-application workflows compared to only 9.5% in AndroidWorld.
- Novel task categories. Mobile World extends beyond standard GUI manipulation by introducing (1) agent-user interaction tasks (22.4%) that evaluate an agent's ability to handle ambiguous instructions through collaborative dialogue, and (2) MCP-augmented tasks (19.9%) that require hy…
