A New Paradigm for GUI Agent Trajectories: FSMs Generate Trajectories at $0.04 Each

GUI Agent轨迹获取新范式：有限状态机合成无限轨迹数据，平均每条轨迹成本低至0.04美元

AutoWebWorld synthesized 29 web environments, 875 pages, and 11,663 verified trajectories at about $0.04 per trajectory, using FSM-defined states, preconditions, and transitions to verify GUI agent tasks instead of human labeling or an LLM judge.

Why it matters: HKR-H/K/R all pass: $0.04 per trace, 11,663 verified traces, and FSM state checks give concrete hooks for GUI-agent data and eval cost. The source is not a top lab release, so it stays in the 78–84 research-tool band.
