UI-TARS 1.5 7B is a specialist — it lives and breathes graphical interfaces, trained to perceive screenshots and translate visual UI context into precise actions or descriptions. It handles grounding tasks like identifying clickable elements and navigating multi-step workflows with notable accuracy for its size. The 7B parameter footprint keeps it deployable on modest hardware, though it's narrowly focused and won't generalize well outside UI-centric tasks.
