Step-GUI - Step-Star Open Source AI Agent Series Models

What is Step-GUI

Step-GUI is the open source AI Agent series model of Step-Star, including the cloud model Step-GUI, the first MCP protocol for GUI Agents, and the industry's first open source end-side model Step-GUI Edge that supports cell phone deployment. focuses on automating the operation of graphical interfaces on cell phones, computers, and other devices through visual understanding technology. It supports execution of tasks in more than 200 apps such as Taobao and Weibo, and can be deployed by individual developers within 10 minutes. It is characterized by end-cloud collaborative design, taking into account privacy protection and efficient computing, and has opened APIs for free use, with supporting technical documentation and development competitions.

Features of Step-GUI

• end-cloud collaboration: Step-GUI adopts an end-cloud synergistic solution, which not only utilizes the powerful computing power of the cloud to handle complex tasks, but also runs locally through the end-side model Step-GUI Edge to protect user privacy and realize the privacy boundaries are knowable and controllable.
• Wide range of application scenarios: Step-GUI is now able to perform tasks in more than 200 APP scenarios such as Taobao, Weibo, Shake, Xiaohongshu, Idle Fish, etc. It greatly expands the capability boundaries of the GUI Agent and meets the needs of users in a variety of scenarios.
• Rapid deployment: Support individual developers and hardware manufacturers to quickly build Agent assistant in the terminal, the fastest 10 minutes can be deployed online, greatly reducing the threshold and time cost of development and deployment.
• Open source end-side model: As the industry's first open source end-side model to support cell phone deployment, Step-GUI Edge can run on cell phones and other end devices, keeping data local and further safeguarding user privacy and data security.
