Runway Solaris: When Software Interfaces Are Generated Frame by Frame
Published August 31, 2026 · Technology On the Net On August 31, 2026, Runway introduced Solaris , a system it calls the first Interface World Model . The pitch is blunt: instead of loading apps and websites that were coded months earlier, generate the interface itself—frame by frame—as someone uses it.

That claim sits at the intersection of video generation, agent training, and product design. It is also early. Solaris is not a public product yet; Runway is collecting early-access requests and working with partners.
