What happened

Runway unveiled Solaris, an Interface World Model that generates interactive interfaces in real time and evolves them based on user actions. It separates reasoning from rendering, allowing real-time visual evolution as users interact with elements.

Why it matters

Solaris could empower non-programmers to shape experiences, but it remains early and faces technical and accessibility challenges that may limit immediate adoption.

Runway introduced Solaris as its first Interface World Model, designed to create interactive interfaces in real time and adapt to user actions. It aims to bypass traditional intermediate representations like code, instead rendering the interface image by image as interactions occur.

The approach separates the thinking model from the rendering process, so a language model plans how the interface should evolve and a world model paints that evolution. Demonstrations look promising, but the platform remains early stage, with notable challenges around text stability, long-session coherence, and overall accessibility.

FOR PEOPLE

Benefits

Solaris could help people design interactive tools without coding.

FOR AI TOOLS AND COMPANIES

Benefits

The system routes user actions to a visual render while separate reasoning guides interface evolution.
