ByteDance Releases UI-TARS-1.5: An Open-Source Multimodal AI Agent

UI-TARS-1.5 is a free, open-source AI tool that can understand and interact with graphical user interfaces, like apps or websites, by using both images and text.

Key Features:

• UI-TARS-1.5 is the newest version in the UI-TARS series, built to automate tasks on computer screens.
• It’s good at seeing, understanding, remembering, and acting—similar to how a person would use a computer.
• It can complete many types of tasks in virtual environments just by looking at the screen and following written instructions.
• The model works from start to finish using only visual input (like screenshots) and natural language (like English or Chinese) to understand and act.
• It can run on various platforms: Windows, macOS, mobile phones, and web browsers.
• It performs very well on standard tests, showing it’s smart at solving problems and better than previous versions.
• You can tell it to do things like check the weather or post on social media just by typing your instructions.
• The tool follows a unified system to work the same way across different platforms.

Limitations:

Sometimes it might make mistakes, like misunderstanding parts of the screen or doing the wrong thing, especially in confusing or new situations.

However, it can learn from user feedback and improve over time, making fewer mistakes.

Background

The name UI-TARS-1.5 comes from the robot “TARS” in the movie Interstellar, highlighting its smart and independent nature.

The specific version released, UI-TARS-1.5-7B, is designed to help with general computer tasks but still performs well in game-related tasks too.
