BlueLM-GUI Technical Report: Real-Device Flywheel for Self-Improving Mobile GUI Agents
A new arXiv technical report introduces BlueLM-GUI, a mobile GUI agent trained end-to-end on real devices rather than in simulated sandboxes. The authors argue that sandbox-based training creates a mismatch with production conditions and propose a self-improving "flywheel" loop that collects and reuses real-device interaction data. It targets the practical obstacles industrial teams face when deploying mobile agents, including data collection cost and device-specific behavior.
