# Runway Unveils Solaris: AI Generates Real-Time Software Interfaces

Runway introduces Solaris, an AI system that generates user interfaces in real time without pre-built code.

Runway has unveiled Solaris, the first model in a new category it calls 'Interface World Models.' [^1]

Instead of running code, the Solaris system generates the user interface frame by frame as users interact with it. [^2]

Runway wants the 'app' as a fixed unit to disappear, proposing that operating systems generate the right interfaces on their own rather than relying on a catalog of prebuilt applications. [^3]

The model renders the interface itself in 720p resolution and responds to clicks, drags, or voice commands. [^4]

In an evaluation across 7,500 pairwise judgments and 30 interaction examples, 250 participants preferred Solaris over coded interfaces for better adherence to instructions in 61% of comparisons. [^5]

Runway argues that conventional visual interfaces require designers and developers to translate designs into code and define interactions in advance, a step Solaris aims to bypass entirely. [^6]

Runway states that 250 participants preferred Solaris for behaving more naturally within the scene in 71% of comparisons against coded interfaces. [^7]
