Is AI video just a prequel? Runway’s CEO thinks world models are next

Runway, the New York-based AI company behind popular video generation tools, has raised close to $860 million at a $5.3 billion valuation. On the latest TechCrunch Equity podcast, co-founder and CEO Cristóbal Valenzuela outlined a vision that extends far beyond Hollywood. He argues that AI video is just a stepping stone to "world models"—AI systems that simulate physical environments for applications in gaming, robotics, and potentially general intelligence. Valenzuela claims the real constraint on filmmaking has never been technology, and that real-time video generation will unlock use cases beyond content creation, such as interactive simulations and nonlinear media.

Runway is now going toe-to-toe with Google and OpenAI in the race to build these world models, but Valenzuela says Runway's approach differs in key ways. He also pushes back on the idea that AI companions are "inherently dystopian," suggesting they could serve beneficial roles. The episode dives into what "nonlinear media" means and why real-time generation changes the game. For professionals, this signals a shift from AI as a content tool to AI as a platform for simulating and interacting with complex environments.
