Dr. Fei Fei Li: preference

16 Nov 2025 Lenny's Podcast The Godmother of AI on jobs, robots, and why world models are next | Dr. Fei-Fei Li

“And in fact, just a couple of weeks ago, we rolled out the world's first real time demoable, real-time video generation on a single H100 GPU. So part of our technology includes that, but I think Marble is very different because we really want creators, designers, developers to have in their hands a model that can give them worlds with 3D structures so they can use it for their work.”

Transcript context

…Because imagining all the exposure therapy stuff, this could be so good for that. That is so cool. Okay, so I should have asked you this before, but I think there's going to be a question of just, how does this differ from things like VO3 and other video generation models? It's pretty clear to me, but I think it might be helpful just to explain how this is different from all the video AI tools people have seen. World Labs' thesis is that spatial intelligence is fundamentally very important, and spatial intelligence is not just about videos. In fact, the world is not passively watching videos passing by. I love, Plato has the allegory of the cave analogy to describe vision. He said that imagine a prisoner tied on his chair, not very humane, but in a cave watching a full life theater in front of him, but the actual life theater that actors are acting is behind his back. It was just lit so that the projection of the action is on a wall of the cave. And then the goal, the task of this prisoner is to figure out what's going on. It's a pretty extreme example, but it really shows, it describes what vision is about, is that to make sense of the 3D world or 4D world out of 2D. So spatial intelligence to me is deeper than only creating that flat 2D world. Spatial intelligence to me is the ability to create, reason, interact, make sense of deeply spatial world, whether it's 2D or 3D or 4D, including dynamics and all that. So World Lab is focusing on that, and of course the ability to create videos per se could be part of this. And in fact, just a couple of weeks ago, we rolled out the world's first real time demoable, real-time video generation on a single H100 GPU. So part of our technology includes that, but I think Marble is very different because we really want creators, designers, developers to have in their hands a model that can give them worlds with 3D structures so they can use it for their work. And that's why Marble is so different. The way I see it is it's a platform for a ton of opportunity to do stuff. As you described, videos are just like, here's a one-off video that's very fun and cool and you could... And that's it. That's it. And you move on.…
