Runway Unveils Solaris, Its First Interface World Model

On September 1, Runway released new research called Solaris, describing it as the first "Interface World Model," along with an official intro video. This marks Runway's move beyond video generation into a new product and research direction.

Confirmed

• Solaris is described as a new type of operating system that can generate interactive interfaces in real time, frame by frame, without writing any code (including HTML/CSS)
• It uses direct rendering: the model generates each frame of the interface directly, without converting visual designs into code first
• According to its technical report, Solaris outperforms frontier LLMs on novel interface generation in both structural similarity and information retention
• Runway's official account (@runwayml) and research community authors (such as @mattshumer) both posted and relayed the announcement, confirming the positioning and capability descriptions above

Why it matters

• "Interface world model" is an entirely new concept: if interfaces themselves can be generated by models in real time, software development could shift from "writing code" to "describing intent," with potential disruption to traditional UI development and even the shape of operating systems
• This direction extends Runway's video/world-model capabilities into interactive interfaces, and its follow-up technical reports and productization progress are worth watching closely
