You can now train mobile agents at scale with deterministic, verifiable rewards in simulation, and the skills transfer well to real devices—solving a major bottleneck in agent research.
MobileGym is a lightweight simulation platform for training mobile app agents that runs hundreds of parallel instances in a browser. It provides verifiable task outcomes through structured JSON states and enables scalable reinforcement learning training, with a benchmark of 416 tasks across 28 apps that shows strong transfer to real devices.
