  "account": "On Monday, Runway unveiled Solaris, marking the debut of a new breed of AI systems known as Interface World Models. This innovative model transforms the traditional process of converting designs into code by directly generating interfaces from visual input. Solaris operates in real-time, learning from user interactions such as clicks and drags to determine what to render next. By eliminating the need for explicit programming of each interaction, Solaris promises a more intuitive and fluid user experience.\n\nUnlike conventional visual interfaces, which require designers and developers to pre-define designs and interactions, Solaris generates every frame and response to user input automatically. This approach allows users to interact directly with the scene itself, creating a continuously evolving and interactive experience. To demonstrate the potential of this technology, Runway showcased examples like dragging a shirt from a rack onto an image of oneself, rearranging furniture in a room, and observing a salad bowl change as ingredients are dragged and dropped.\n\nSolaris is powered by Runway's Gen-4.5 video generation model and follows a similar architecture to GWM-1, its general world model. It processes user interactions as signals to generate subsequent frames, learning from these interactions to respond visually without the need for explicit coding. The model cuts down on denoising steps, learns to generate frames autoregressively, and is trained on its own outputs to ensure high visual quality during extended sessions.\n\nTo enhance usability, Solaris is paired with a language model that interprets user requests, decides on the next action for the application, and generates prompts to guide rendering. This combination enables Solaris to generate behavior in real-time, responsive to user actions. The company argues that conventional coded interfaces often struggle to generalize when layouts change, but Solaris can adapt to ever-changing interfaces and new layouts without prior programming.\n\nRunway's adoption of Interface World Models encompasses three new software capabilities: visual, interactive interfaces that remain coherent and open-ended. By bypassing the step of translating visual designs into code, the image users see is literally the application itself. Runway conducted evaluations comparing coded and generated interfaces, demonstrating that Solaris preserves the complete visual and semantic state of interfaces more effectively than traditional methods. In user studies, participants preferred Solaris over coded interfaces for better adherence to instructions and more natural behavior in 61% and 71% of comparisons, respectively. The evaluations suggest that Interface World Models generate interactions that remain coherent within the scene, unlike coded interfaces which treat each interaction as an isolated update.\n\nLooking ahead, Runway anticipates interface generation will follow the trajectory of image and video generation, with successive models improving in speed, coherence, and controllability. Key challenges include maintaining legible text and coherence over long sessions, grounding generation in richer, verified context, and integrating generated interfaces with existing software systems. Runway envisions a new operating layer capable of generating interfaces tailored to various user needs, potentially redefining the basic unit of interaction from apps to more dynamic, generated experiences. The company is currently working with partners to launch Solaris publicly and is accepting requests for early access.",
