The Open-Source Multimodal AI Agent Stack: Connecting Cutting-Edge AI Models and Agent Infra

← AI and models
UI-TARS: AI computer control agent. Operates your desktop and browser using visual AI models.

In simple English

This tool lets you type what you want done on your computer, like booking a flight or changing a settings file. A visual AI reads your screen, moves your mouse, and clicks the right buttons for you. You can run it on your own machine or connect to a remote one. It requires a powerful vision model API key to work, which can cost money based on usage. Setting it up takes some technical steps.

What it is

A multimodal AI agent desktop application and command-line tool. It connects large language models with screen capture and input simulation to operate graphical user interfaces.

What it is good for

Solo builders who want to automate repetitive desktop tasks, test web applications through a browser, or build custom task workflows using natural language.
