What If Apps Didn’t Need Code?

Runway co-founder Anastasis Germanidis explains Solaris, an “interface world model” that generates software frame by frame instead of rendering a traditional interface from HTML and CSS.

The model reacts directly to clicks, drags, and keyboard input, while language models or agents can still handle logic and tool calls behind the scenes. The conversation explores personalized interfaces, local-versus-cloud world-model architecture, robotics simulation, and Runway’s longer-term bet that world models could become a new foundation for software, games, and physical AI.
