Runway, the company known for AI video generation, has released Solaris, a system it calls an Interface World Model. Instead of running an app or website built from code, Solaris generates the entire screen as video, frame by frame, live, as a person clicks, drags, or types.
That sounds abstract, so picture how software works today. A designer draws a screen, an engineer turns that drawing into code, and the code decides what happens when someone clicks a button. That code gets built once and stays fixed until a developer changes it. Solaris skips the code step entirely. The screen itself is generated on the spot, and it can respond to an action nobody explicitly programmed for.
Runway is not a small player making a wild claim. It built its business on Gen-4.5, a video generation model that topped independent industry rankings earlier this year, and the company recently raised more than three hundred million dollars at a valuation above five billion dollars. Its revenue reportedly grew from roughly one hundred twenty million dollars in 2024 to around three hundred million this year. That funding and growth is part of why this launch deserves attention rather than a shrug.
Runway is also not alone in chasing this idea. Google DeepMind has been building its own version, called Genie, which generates playable, interactive worlds from a text description. Both companies are betting that the next big shift in AI is not just answering questions in text, but generating entire environments a person or another piece of software can act inside of. That is a real trend, not a one-off product stunt.
One detail is worth slowing down on. Runway tested Solaris against an interface built by another AI, Claude Opus 5, and reported that people preferred Solaris in most head to head comparisons. That is a fair test between two AI approaches, but it is not the same as beating the storefront your company already runs, one that was designed and refined by real people over months. Treat the comparison as a signal of promise, not proof this beats what you have today.
The rough edges matter for anyone thinking about using this. Runway says readable text is still one of the hardest problems, which is a real issue for a checkout page, an insurance form, or anything with prices and legal wording. Long sessions can drift and lose consistency. Generating a new screen for every click also costs far more than serving a normal webpage, and nobody has published what that costs at real business volume.
None of this is available as a product yet. Access is by invite through a signup form, aimed at partners rather than the general public. The realistic path for most businesses is to watch this space for a year or two, starting with low-risk uses like marketing pages, virtual showrooms, or product demos, well before anything resembling a checkout page or a customer account portal.
