Runway Solaris Generates Stateful App Interfaces Frame by Frame Without Code
- Runway Solaris generates an application as a live stream of rendered frames, with no HTML, CSS, JavaScript, or other code representation in the described interface loop.
- Runway calls Solaris its first Interface World Model: clicks, drags, and text input condition the model to generate the next visual frame and interaction state.
- Runway says Solaris retrains Gen-4.5 for autoregressive frame generation, so each frame depends on previously generated frames instead of a full video clip being refined in batch.
- The company published its Solaris research post on August 31 and argues that pixel-level generation removes the usual translation from visual design into code.
