Runway Introduces "Solaris": An Experimental Model That Generates Interfaces in Real Time Instead of Code
Runway announced an unusual research project: Solaris. The idea is radical — an app interface is formed not from pre-written code, but by a model generating the image frame by frame as you click, drag, and type.
In brief
- What was announced: on August 31, Runway introduced Solaris as an "Interface World Model." In a traditional interface every button and window is coded; here there's no hidden code layer — the model takes your interactions (clicks, drags, text) as input and generates the interface directly. It runs at 720p, targeting under 500 ms latency. It's built on Runway's Gen-4.5 video model plus a GWM-1 "world model."
- What's different: objects become context-sensitive "tools," and the environment is "alive" — reflections shift, objects respond naturally. It promises open-ended interaction beyond predefined workflows.
- How good (Runway's own user study): 250 participants, roughly 7,500 pairwise judgments, 30 examples. For following instructions, Solaris was preferred 61% vs. 24% for a coded interface (the rest tied); for "natural behavior," Solaris 71% vs. 21%.
- Status and open problems: it's NOT available yet — "coming soon," with a waitlist, and no pricing given. Runway's own listed limits: stable text generation is unsolved, there are trust/hallucination concerns for commercial use, long-session coherence is still in research, and accessibility/screen-reader support is pending.
Our take
This is a research preview of a genuinely different idea: instead of coding a UI, a model "imagines" it in real time as you use it. It's striking because it opens a small window onto a possible future where software interfaces are generated rather than built. But keep your feet on the ground: there's no product yet (waitlist), the evidence is Runway's own preference study, and Runway itself lists serious open problems — text isn't reliable, hallucination/trust is unsolved, long sessions don't stay coherent, and accessibility isn't there. For our audience, this isn't something to use today. The honest read: a thought-provoking research direction worth watching — but years from becoming a dependable product.
