The article details the significant open-source GELab-Zero project by Step-Stars, aimed at solving the engineering infrastructure challenges faced by mobile Agent's large-scale implementation. The core of this project includes three parts: a 4B GUI Agent model GELab-Zero-4B-preview that can run locally, which refreshes the performance records of models of the same size on multiple GUI leaderboards, achieves SOTA results, and can efficiently execute complex tasks and understand vague instructions; a set of plug-and-play complete inference engineering infrastructure, which realizes one-click multi-terminal deployment, distributed task orchestration, and multimodal Agent paradigm, greatly reducing the development threshold; and an evaluation standard AndroidDaily built on real business scenarios, focusing on high-frequency applications in life service categories, and using static and end-to-end dual-track evaluation to more realistically measure the practical value of GUI Agents. The GELab-Zero open-source project aims to accelerate GUI Agent innovation and implementation by enabling developers to focus on value creation.
