Introduction

MobiZen-GUI-4B is a native GUI agent model built on Qwen3-VL. It is trained on a large, hand-curated corpus of Chinese mobile GUI interactions, the model has learned from hundreds of thousands of real Chinese app sessions spanning e-commerce, transport, social, and finance. Each record includes screenshots, touch traces, and Chinese instructions, giving the agent deep insight into Chinese UI conventions and workflows.

The goal of MobiZen-GUI-4B is to make it easier—and faster—to build and ship Chinese Mobile GUI agents. It delivers:

• A 4-billion-parameter agent that runs completely on your own desktop or laptop.
• Fast execution speed, relying only on a single image and historical actions. It relies solely on a single current image and historical actions, requiring no additional information, resulting in fast execution speed.
• A turnkey inference kit that auto-handles ADB links and pulls in every required library.

What it can do

• Runs on everyday machines: engineered for snappy response while keeping data on-device.
• Sees and acts: spots buttons, text fields, lists, etc., then taps, types, swipes, or waits as needed.
• Masters long procedures: carries out multi-stage jobs in food, ride-hailing, shopping, social, and other apps.
• Works out of the box: copes with brand-new apps and shifting layouts without any extra fine-tuning or domain-specific tweaks.
