Abstract: Building agents that generalize across web, desktop, and mobile environments
remains an open challenge, as prior systems rely on environment-specific
interfaces that limit cross-platform deployment. We introduce Surfer 2, a
unified architecture operating purely from visual observations that achieves
state-of-the-art performance across all three environments. Surfer 2 integrates
hierarchical context management, decoupled planning and execution, and
self-verification with adaptive recovery, enabling reliable operation over long
task horizons. Our system achieves 97.1% accuracy on WebVoyager, 69.6% on
WebArena, 60.1% on OSWorld, and 87.1% on AndroidWorld, outperforming all prior
systems without task-specific fine-tuning. With multiple attempts, Surfer 2
exceeds human performance on all benchmarks. These results demonstrate that
systematic orchestration amplifies foundation model capabilities and enables
general-purpose computer control through visual interaction alone, while
calling for a next-generation vision language model to achieve Pareto-optimal
cost-efficiency.
