Runway unveils Solaris interface world model

Solaris is a compelling glimpse at post-DOM software—but it remains a research bet, not a drop-in app runtime.

• –It collapses design, behavior, and rendering into one model, letting developers describe interactions instead of coding every workflow.
• –Generated interfaces could give computer-use agents more varied environments for training and evaluation.
• –Runway reports Solaris beat a coded interface powered by Claude Opus 5 in user preference, but the comparison is company-run rather than an independent benchmark.
• –Legible text, long-session consistency, trust, accessibility, and deterministic behavior remain major obstacles.
• –If it works at scale, frontend engineering shifts toward grounding, testing, and evaluating generated environments.
