The actual breakthrough with Genie is being able to turn around and look back, and seeing the same scene that was there before. A few other labs have similar world simulators, but they all struggle badly with keeping coherence of things not in view. Hence why they always walk forwards and never look around.
- sfn42 9mo agoAnd what if I go somewhere then go back there a week later?
- jsheard 9mo agoBest they can do is 60 seconds, for now at least.
- autonomousErwin 9mo agoMakes you wonder what the TTL caching for our universe is.
- dabbz 9mo agoWhatever the speed of light is I would imagine
- jacquesm 9mo agoNo, that's just an optimization that saved on computing resources. It effectively allows the party that runs this simulation to have a limited world to simulate. Dark matter is the other half of that trick. Both were invented by one Bebele Zropaxhodb after a particularly interesting party in the universe just above this one...
- autonomousErwin 9mo agoThat's the rendering speed.

- nozbufferHere 9mo agoStill amazed it took ML people so long to realize they needed and explicit representation to cache stuff.
- Legend2440 9mo agoGenie does not use an explicit representation: >Genie 3’s consistency is an emergent capability. Other methods such as NeRFs and Gaussian Splatting also allow consistent navigable 3D environments, but depend on the provision of an explicit 3D representation. By contrast, worlds generated by Genie 3 are far more dynamic and rich because they’re created frame by frame based on the world description and actions by the user.
- emmettm 9mo agoThe representation is learned. Also, see Sutter's "Bitter Lesson" essay
- abraxas 9mo agoWhat about Fei Fei Li's lab? I think they are generating true 3D worlds rather than frames of a video? Although that probably precludes her from having animations in those worlds...
- forrestthewoods 9mo agoCan they? Is there a video of someone standing in place and spinning the camera 1080 degrees?
- postexitus 9mo agoThey achieve that by not generating the scene you see, but a lens warped version of 360 degree view. So you turning the other way doesn't delete what's happening / generated on your back side. However I expect it to breakdown if you put a blocker in between and remove it. i.e. go behind a wall and come back, or enter and exit a building. Would be nice to play with.
