OS-Genesis: Automating GUI Agent Trajectory Construction via Reverse Task Synthesis
Shanghai AI Laboratory; The University of Hong Kong; Johns Hopkins University; Shanghai Jiao Tong University; University of Oxford; Hong Kong University of Science and Technology
This paper introduces OS-Genesis, a novel pipeline for generating high-quality trajectory data aimed at training GUI agents. It tackles the limitations of traditional data collection methods by enabling agents to first interact with environments and then retrospectively generate tasks. This approach brings about improved data quality and diversity, leading to better agent performance on challenging benchmarks. OS-Genesis stands out in its efficiency and ability to produce superior trajectory generation when compared to the traditional approaches. Overall, I found the innovative method of reverse task synthesis particularly effective in enhancing agent training.
