[Paper] The Unreasonable Effectiveness of Scaling Agents for Computer Use
Behavior Best-of-N (bBoN) revolutionizes computer-use agents by generating multiple solution attempts and intelligently selecting the best one. This “wide scaling” approach, developed by Simular Research, dramatically improves task success rates, reaching 69.9% accuracy on benchmarks—nearly matching human performance at 72%. The framework’s key components, the Behavior Narrative Generator and Best-of-N Judge, efficiently summarize and compare solution trajectories. Built upon Agent S2 and introducing Agent S3, bBoN demonstrates consistent improvements with increased rollouts and model diversity. It shows strong generalization across different operating systems and suggests a promising direction for deploying reliable computer-use agents in real-world applications, despite some limitations in shared resource management.
