UI-TARS 1.5 7B

UI-TARS 1.5 is a downloadable vision-language agent for screen-based tasks.

Model design

The release uses reinforcement learning to improve reasoning before an action. The model card links a separate desktop application and execution code. The checkpoint alone does not supply that runtime.UI-TARS 1.5 7B official model card

Practical use

Practical guidance. Evaluate complete actions in a controlled workspace. Check whether the agent selected the correct target and observed the result, rather than judging only its textual plan.
