According to CoinMeta, OneMillion.AI stated that the next generation of App may not have a fixed interface, and Jev allows the App interface to be reorganized in real-time. Engineers from Vercel Labs are integrating json-render with Jev to test the ability to directly combine UI during runtime. json-render is responsible for preparing components such as buttons, cards, and input fields in advance, while Jev decides on the selection and ordering of these components, which are then handed over to the UI renderer. During the demonstration, the jsonl mode took 3.21 seconds from request to completion, whereas Jev only took 0.88 seconds. In the future, the App interface may no longer be fixed and could be dynamically assembled based on the user, task, and status. The Jev demonstration has reduced the generation time to within 1 second, enhancing the sense of real-time interaction. Runway is also exploring a similar approach, using a world model to generate the interface frame by frame, bypassing traditional code and components.
