MobileGym: A Verifiable and Highly Parallel Simulation Platform for Mobile GUI Agent Research

Excerpt

arXiv:2605.26114v3 Announce Type: replace-cross Abstract: We present MobileGym, a browser-hosted, lightweight, fully controllable environment for everyday mobile use, targeting interaction fidelity without replicating proprietary backends. It enables two capabilities previously out of reach for everyday apps: verifiable outcome signals through deterministic state-based judging over structured JSON state, and scalable online RL through low-cost parallel rollouts. The full environment state is cap
