OpenMobile-2 proves open-source smartphone agents can rival proprietary models

Researchers from Nanjing University, SenseTime and other universities released OpenMobile-2, two smartphone agent models built on Qwen3.5 (9B) and Qwen3.6 (27B) parameters, together with the full training environment, data and reproduction instructions. The training ground covers more than 110 apps, including 35 rebuilt Chinese and global apps, and the larger model reaches 79.9 points on AndroidWorld and 59.6 on SPA-Bench with real devices. Holding data constant and increasing app variety raised success on unseen apps from 60.7 to 67.5 percent.
