Runway has been on a tear over the past couple months. Viral HORSE Video contest Solaris: the world's first Interface World Model Praxis-1: open-weight World Action Model for robotics Project Continuum: operating system research application built around real-time interfaces A video model. An interface model. A robotics model. An operating system. Are you getting it? These are not separate pretrains. They’re different applications, built around the same General World Model backbone, with different post-training on top. All of them are examples of what you can do when you can simulate any pixel. So I asked co-CEO Anastasis Germanidis to co-write an essay with me explaining how video, interfaces, operating systems, and robotics all fit together, why video was the right starting point for World Models, where the world is heading if Runway’s bets are right, and whether or not, as someone who simulates worlds, he believes we’re living in a simulation. Welcome to the future. Enjoy! (Video, of course, made with Runway)

Researchers at Harvard and Brigham and Women’s Hospital found that transplanted hearts shift toward the biological age of their recipients. Old hearts get younger in young bodies, and young hearts get older in older ones. Which is nuts. Today, we're launching a partnership with our friends @runwayml to, among other things, bring one of the stories from each week's Dose to life in video. I'm not great at it yet, but not bad for a few prompts! And I'm excited to get better. I have zero talent in film/video, but I can write, which now means that I can make movies. Age of miracles.
