Runway Says World Models Start With Video

Runway’s CTO says the company’s path to building a world model began with mastering video generation. After outperforming Google and OpenAI on the Video Arena leaderboard with Gen 4.5, Runway claims GWM-1 is more general than competitors like Google’s Genie-3. The company argues that pixel-level prediction at scale is key to creating general-purpose simulations that understand how the real world works.
