This looks interesting, but can someone explain to me how this is different from video generators using the previous frames as inputs to expand on the next frame? Is this more than recursive video? If so, how?

See the demo on their homepage. Calling it a world simulator is a marketing gimmick. It's a worse video generator but you can interact with it in real time and direct the video a little bit. Next version of this thing will be worth looking, this one isnt.

It's plato's cave, but in color! https://en.wikipedia.org/wiki/Allegory_of_the_cave / https://www.youtube.com/watch?v=1RWOpQXTltA&t=56s

Yes, it should be called an AI Metaverse.

It does do a nice job of short term prediction. That's useful as a component of common sense.

As a machine learning researcher, I don't get why these are called world models.

Visually, they are stunning. But it's nowhere near physical. I mean look at that video with the girl and lion. The tail teleports between legs and then becomes attached to the girl instead of the tiger.

Just because the visuals are high quality doesn't mean it's a world model or has learned physics. I feel like we're conflating these things. I'm much happier to call something a world model if its visual quality is dogshit but it is consistent with its world. And I say its world because it doesn't need to be consistent with ours

The input images are stunning, model's result is another disappointing trip to uncanny valley. But we feel Ok as long as the sequence doesn't horribly contradict the original image or sound. That is the world model.

It's called "world models" because it's a grift. An out-in-the-open, shameless grift. Investors, pile on.

why would you assume anything about "the next version"?
