2 Apr 2026 Latent Space Moonlake: Causal World Models should be Multimodal, Interactive, and Efficient — with Chris Manning and Fan-yun Sun

“I think Sun is also too polite to point out that, both like Google’s genie, demos as well as world Labs is marble, do not have interactive worlds.”

Transcript context

…Very, very detailed. You gotta you don’t even realize it, right? Like when a video is generated, what happens when a ball strikes a pin, right? So first, like you, there’s audio in that, like audio triggers happens, score increments, the world changes. Like pins have to start dropping. There’s a timer that goes on. It’s just like very similar to how now we’re used to reasoning for language models. There’s a whole state of what happens. So geometry, physics, all this stuff. And then yeah, there’s kind of that single prompt. So asset, ation all this stuff. It’s like a, it’s a nice view to see what’s going on. I think Sun is also too polite to point out that, both like Google’s genie, demos as well as world Labs is marble, do not have interactive worlds. That’s the benefit of having a reasoning model, right? Like, because you can, you can say, oh, like maybe in this particular context, I want to learn how to bowl. And then you can say, okay, then what is it important when it comes to learning how to bowl? Okay, maybe it’s like I need to understand the, the basic of like, physics and I want to throw it over [00:22:00] them. I wanna know that when I, when it resets it’s a new game. So I know that yeah, basically, you know to pick up the ball, you know that ball’s gonna cause the pins to fall down. You know that what’s important to this particular bowling game is to score and you know that the score corresponds to the number of pins that fell down. So it’s just like, if it’s a model that sort of knows what it. Looks like, knows what a bowling game looks like, but doesn’t actually allows you to practice over and over again and to understand that, oh, like what it takes to actually get a high score. Then it sort of doesn’t actually allow you to learn what you set out to learn within the world model. And I think this is really just one example of showing like the advantages of the approach that we’re taking over most the, let’s call it the zeitgeist, is today, when people talk about clinical role models,…
