L3G-World: an AI world that remembers what's behind you
KAIST's L3G-World generates an endless 3D world in real time and keeps a 3D Gaussian memory, so places stay the same when you turn around. Research demo: ~9 FPS at 480x832 on one H100; code not released.

Turn around in most AI-generated worlds and what was behind you may be gone. L3G-World, from KAIST AI, is built to remember.
How
As it generates frames, it builds a latent 3D Gaussian memory of the scene, and uses that memory when you look back. That's the difference from world models that only remember recent frames.
Research demo, not a product
