+## Overview

+
+We introduce OS-Genesis, an interaction-driven pipeline that synthesizes high-quality and diverse GUI agent trajectory data without human supervision. By leveraging reverse task synthesis, OS-Genesis enables effective training of GUI agents to achieve superior performance on dynamic benchmarks such as AndroidWorld and WebArena.
+
+## Quick Start
+OS-Genesis-4B-AW is a mobile action model finetuned from [InternVL2-4B](https://huggingface.co/OpenGVLab/InternVL2-4B).
+
+###  OS-Genesis AW Family Models
+In the following table, we provide an overview of the OS-Genesis AW Family Models used for evaluating the AndroidControl Benchmark.

+### Inference Example
+First, install the `transformers` library:
+
+```
+pip install transformers
+```
+
+For additional dependencies, please refer to the [InternVL2 documentation](https://internvl.readthedocs.io/en/latest/get_started/installation.html).
+
+For evaluating the AndroidWorld Benchmark, please refer to the [**evaluation code**](https://github.com/OS-Copilot/OS-Genesis/tree/main/evaluation/android_world).
+
+Inference code example:
+```python
