Runway, the New York-based AI company valued at $5.3 billion, has become a key player in the rapidly evolving field of AI-generated video. But according to co-founder and CEO Cristóbal Valenzuela, the technology’s true potential extends far beyond Hollywood. In a recent episode of TechCrunch’s Equity podcast, Valenzuela outlined a vision where video generation serves as a stepping stone to general world models—systems that can simulate physics, environments, and even social interactions in real time.
From video clips to world simulators
Runway has raised nearly $860 million to date, competing directly with labs like Google DeepMind and OpenAI. While its models are best known for generating short video clips from text prompts, Valenzuela argues that the next logical step is building models that understand the world in three dimensions and over time. “Video is just a representation,” he said on the podcast. “What we really want are models that can reason about the world, not just generate pixels.”

This shift toward general world models opens up applications in gaming, robotics, and simulation. In gaming, real-time video generation could create dynamic, nonlinear narratives that respond to player actions. In robotics, world models could help machines address unfamiliar environments without explicit programming. Valenzuela described this as “nonlinear media,” where the output is not a fixed sequence but a responsive, interactive environment.
How Runway differs from Google and OpenAI
While Google and OpenAI are also investing heavily in world models, Valenzuela says Runway’s approach is distinct. “They’re building infrastructure for general intelligence. We’re building creative tools first,” he explained. Runway’s models are designed with artists, filmmakers, and game developers in mind, prioritizing real-time interactivity and creative control over raw computational scale.

This focus on usability has helped Runway carve out a niche. The company’s tools are already used in commercial film production, advertising, and independent content creation. Valenzuela believes that making these models accessible to non-engineers will accelerate adoption and uncover use cases that large labs might overlook.
Real-time generation and nonlinear media
One of the most ambitious goals Valenzuela discussed is real-time video generation. Currently, most AI video tools require minutes or hours to produce a short clip. Runway is working toward generating video in real time, which would enable live interactive experiences—think video games where every frame is generated on the fly, or virtual environments that adapt to user input instantly.
“Nonlinear media means the story changes based on what you do,” Valenzuela said. “That’s not just a new format. It’s a new medium.” This concept has implications beyond entertainment. Real-time world models could be used in training simulations, architectural visualization, and even scientific research.
Pushing back on dystopian narratives
Valenzuela also addressed concerns about AI companions and the potential for dystopian outcomes. He pushed back on the idea that AI-powered interactions are inherently harmful. “Technology is a tool. The outcome depends on how we design it,” he said. Runway’s focus remains on creative empowerment rather than replacing human decision-making, though Valenzuela acknowledged that the industry as a whole must remain vigilant about ethical design.
Why this matters
The evolution from AI video to world models represents a fundamental shift in how machines understand and interact with the physical world. For readers, this means that the tools used to create entertainment today could soon underpin everything from autonomous vehicles to virtual reality. Runway’s bet is that the path to general intelligence runs through creativity—not just computation.
Conclusion
Runway’s vision extends well beyond the current wave of AI video tools. By focusing on real-time generation, nonlinear media, and accessible creative tools, the company is positioning itself at the intersection of entertainment, simulation, and general intelligence. As Valenzuela put it, “Video was never the endgame. It was just the first frame.”
FAQs
Q1: What is a world model in AI?
A world model is an AI system that can simulate physical environments, predict outcomes, and reason about cause and effect—similar to how humans understand the world. Runway aims to build these models for gaming, robotics, and interactive media.
Q2: How does Runway differ from OpenAI and Google?
Runway focuses on creative tools for artists and filmmakers, emphasizing real-time interactivity and ease of use, while larger labs prioritize general-purpose intelligence and infrastructure.
Q3: What is nonlinear media?
Nonlinear media refers to content that changes in real time based on user input, such as interactive video games or adaptive narratives. Runway is developing AI models capable of generating this type of media on the fly.
