MobileGym: Verifiable Simulation Platform Enables Scalable Online RL for Mobile GUI Agents
arXiv·medium signal
Introduces MobileGym, a browser-hosted lightweight environment for mobile GUI agent research with deterministic state-based judging over structured JSON state and scalable parallel rollouts. Solves two key gaps: verifiable outcome signals (not screenshot heuristics) and scalable online RL for everyday mobile apps. Makes mobile agent training reproducible and affordable.
