And so this is a holdout set.

So this clip was never seen before at training time.

As you can see, it has a spatial memory.

This is about a 20-second-ish generation.

Here's what's fascinating.

This is an explosion that occurs, and you can see that in the physical world, the camera would shake, and in the game, that would never happen.

So you see the world model inherits the physical world camera shake, but the actual...

A game never does that, which is sort of, that to us was quite fascinating, right?

Also did the models that I just showed you that we used to transfer over from video.

The two of those combined will allow us to like push way beyond games in terms of training.

um this is another interesting so this is a world model this is rapid camera motion so again this is stuff that we're literally just taking one second from here in the context and the actions and replaying it here right um and so you'll you never essentially have um uh like what we're saying is the skill that you see in the clips that like the speed and the movement that also pays off at training time when you're doing world models um

This is my favorite example.

So this shows that the role model is capable of performing with partial observability.

So what you're going to see is, again, you're replaying the actions from here and here.

using one second of video context.

Everything after that is completely generated.

So what you're going to see is the model is going to encounter, in this case, smoke.

Normally now models break down.

What you actually see is it comes out in the same place.

And so it's capable of, even with partial observability, still maintaining its position in the world.
