As AI technology continues to advance, understanding user interfaces (UI) has become a key challenge in creating intuitive and useful AI applications. Recently, researchers at Apple introduced UI-JEPA in a new paper, an architecture designed for lightweight, device-side UI understanding that maintains high performance while significantly reducing the computational requirements for UI understanding. The challenge of UI understanding lies in processing cross-modal features, including images and natural language, to capture temporal relationships within UI sequences. Despite the complexity, multimodal large language models...
