**UI-Voyager** is a novel two-stage self-evolving mobile GUI agent fine-tuned from [Qwen3-VL-4B-Instruct](https://huggingface.co/Qwen/Qwen3-VL-4B-Instruct). Our 4B model achieves a **81.0%** success rate on the [AndroidWorld](https://github.com/google-research/android_world) benchmark, outperforming numerous recent baselines and **exceeding human-level performance**.

  <em>Overview of UI-Voyager performance on AndroidWorld</em>
</p>

## Highlights

- 🏆 **State-of-the-Art Performance**: Achieves **81.0%** success rate on AndroidWorld, surpassing human-level performance.
- 🔄 **Self-Evolving**: A two-stage training paradigm that learns from failed experiences to continuously improve.
- 📱 **Mobile GUI Agent**: Specialized for operating mobile device interfaces — recognizing UI elements, understanding functions, and completing tasks autonomously.
- 🧠 **Built on Qwen3-VL-4B**: Inherits the powerful vision-language capabilities of Qwen3-VL-4B-Instruct, including advanced visual perception, OCR, and multimodal reasoning.
