UI-TARS

ByteDance's open-weights vision-language agent for GUI control. Prompt templates cover desktop and mobile; browser automation is a separate sibling project.

An open-weights GUI agent model with a companion desktop application — unusual in a field where the capable models are almost all hosted. Because the weights are available, it can run entirely on your own hardware.

Best for

Air-gapped or privacy-constrained deployments where nothing may leave the machine.

Watch out

The directory previously recorded this as controlling both a desktop and a browser. The repository documents desktop and mobile use, and points at separate projects for the desktop application and for web automation, so browser control is not this repository's job. The README's most recent dated update is September 2025.
