Is AI video just a prequel? Runway’s CEO thinks world models are next
TL;DR
AI-generated video has gone from novelty to genuine creative tool almost overnight, and Runway is right at the center of that shift. The New York-based company has raised nearly $860 million at a $5.3 billion valuation, with its models going head-to-head against Google and OpenAI. CEO Cristóbal Valenzuela believes AI video is just the prequel: the next leap is world models — systems that don't just generate clips, but simulate full interactive worlds.
Nauti's Take
Nauti finds Valenzuela's framing genuinely interesting: treating AI video as just the prequel to world models means thinking about the problem at the right scale — interactive simulated worlds could reshape robotics, gaming, and industrial training. The risk lives in the gap between demo and product: world models need 10x more compute, clean physics, and consistent identity over time — areas where even today's best models stumble.
Exciting for research and investors, but not yet a serious option for production workflows.
