“We actually believe that this is going to be the next paradigm of rendering. So it's going to replace how rasterizers, it's going to replace DLSS today because it not only has these pixel prior that's learned from the world, such that you can literally play any game in photorealistic styles”

Opinion
Sun: Pixel-coherent world simulators are overrated for causal reasoning and embodied AI
“Having a world simulator that can produce pixel coherency is very, very useful for games and, you know, marketing and all these things, but it's not as useful as people think when it comes to causal reasoning, when it comes to embodied AI.”

Sun: Synthetic data matches real-world data for multimodal model pre-training
“We were actually generating a lot of synthetic data and showing that, hey, you can actually, these synthetic data are actually as useful as real-world data when it comes to multimodal pre-training.”

Sun: Using structural abstraction in AI does not contradict Bitter Lesson
“I do feel like sometimes people confuse like, oh, like we're taking an, a method with abstraction. That means they don't believe in bitter lesson. Like that's just false, right? Like we are believers in bitter lesson, but then I feel like the question that we …”

Sun: Moonlake splits world modeling into multimodal reasoning and Reverie rendering
“Within our world modeling framework, we think there are two models that we train, right? Like there's the multimodal reasoning model that we just talked about that essentially handles Mainly the causality, the persistency, and logic, determinism, determinism o…”

Sun: Code modifies physical rules better than purely data-driven models
