Plain Language Accessible to non-experts
Imagine you're in a huge mall looking for a specific item. Traditional methods involve using a map (similar to HTML or AXTree) to find the item's location, but these maps might not be detailed or accurate enough. Aria-UI acts like a smart shopping assistant, able to find the item you need just by observing the mall's layout and customer behavior. It analyzes visual information and shopping history to help you quickly locate the target item in a complex environment.

Abstract
Digital agents for automating tasks across different platforms by directly manipulating the GUIs are increasingly important. For these agents, grounding from language instructions to target elements remains a significant challenge due to reliance on HTML or AXTree inputs. In this paper, we introduce Aria-UI, a large multimodal model specifically designed for GUI grounding. Aria-UI adopts a pure-vision approach, eschewing reliance on auxiliary inputs. To adapt to heterogeneous planning instructions, we propose a scalable data pipeline that synthesizes diverse and high-quality instruction samples for grounding. To handle dynamic contexts in task performing, Aria-UI incorporates textual and text-image interleaved action histories, enabling robust context-aware reasoning for grounding. Aria-UI sets new state-of-the-art results across offline and online agent benchmarks, outperforming both vision-only and AXTree-reliant baselines. We release all training data and model checkpoints to foster further research at https://ariaui.github.io.
