Key Findings

Methodology

VenusBench-Mobile evaluates using user-intent-driven task design and capability-oriented annotation, covering 10 user intent categories and 80 environment variations. This approach allows for fine-grained behavior analysis, revealing deficiencies in perception and memory.

Key Results

  • On VenusBench-Mobile, current SOTA agents achieve only a 36.9% success rate, significantly lower than traditional benchmarks, indicating higher task difficulty.
  • Diagnostic analysis shows failures are primarily due to deficiencies in perception and memory, often obscured by coarse evaluations.
  • Even the strongest agents achieve near-zero success under environment variations, exposing their brittleness to realistic distribution shifts.

Significance

VenusBench-Mobile reveals the shortcomings of current mobile GUI agents in real-world deployment through more challenging and realistic tasks, providing a crucial evaluation benchmark to advance more general and robust agents.

Technical Contribution

The study introduces a user-intent-driven task design and capability-oriented annotation scheme, enabling fine-grained failure attribution analysis, distinct from existing coarse success rate evaluations.

Novelty

VenusBench-Mobile is the first benchmark to design tasks from a user-intent perspective, breaking away from previous app-centric evaluation paradigms.

Limitations

  • Current benchmarking is primarily conducted in simulated environments, which may not fully reflect real-world complexity.

Abstract

Existing online benchmarks for mobile GUI agents remain largely app-centric and task-homogeneous, failing to reflect the diversity and instability of real-world mobile usage. To this end, we introduce VenusBench-Mobile, a challenging online benchmark for evaluating general-purpose mobile GUI agents under realistic, user-centric conditions. VenusBench-Mobile builds two core evaluation pillars: defining what to evaluate via user-intent-driven task design that reflects real mobile usage, and how to evaluate through a capability-oriented annotation scheme for fine-grained agent behavior analysis. Extensive evaluation of state-of-the-art mobile GUI agents reveals large performance gaps relative to prior benchmarks, indicating that VenusBench-Mobile poses substantially more challenging and realistic tasks and that current agents remain far from reliable real-world deployment. Diagnostic analysis further shows that failures are dominated by deficiencies in perception and memory, which are largely obscured by coarse-grained evaluations. Moreover, even the strongest agents exhibit near-zero success under environment variations, highlighting their brittleness in realistic settings. Based on these insights, we believe VenusBench-Mobile provides an important stepping stone toward robust real-world deployment of mobile GUI agents.
