I still want to know the definition of a world model, because it seems that what they are doing now is a very basic model of GS (not sure if it is self-developed) and a GS browser.

World model is a 3d game engine, which uses neural net to compute screen pixels instead of rasterizing triangles with textures or ray-tracing.

It is different from video generators, because it also accepts control inputs (ie. keyboard, mouse).

I think a robot would want to know a little more about the world though? For instance, picking up a spatula requires less force than picking up a an anvil. So you would want to know about the mass of things.
