The hook
Runway just shipped Solaris—a model that generates UI frames in real time instead of executing code. First in a new category: Interface World Models.
AI company Runway has unveiled Solaris, the first model in a new category it calls "Interface World Models." Instead of running code, the system generates the user interface frame by frame as you interact with it.
