Thanks for braving the crowd here, you will unfortunately only find hard questions.

Anyway, about my second question: why are the videos only half second ish long? Does the model unravel after that?

11b params is already pretty large considering the stable diffusion and LLM scale. How much higher do we need to scale until we get something useful beyond simple setups?

The bigger issue is lack of generating novel content rather than a total "unravel". We focus on OOD images because our motivation is generating diverse environments, but these are much harder to play for longer vs images closer to the training videos. It is interesting because one of the things you gain when going from 1B->10B is the OOD images working at all. Note it is not even trivial to detect the character given our model does not train with any labels or have any inductive biases to do so.

Point of clarification -- we don't expect bigger models to be the only way to improve this and are working on innovations on the modeling side, however we don't want to overlook the significance of scaling either :)

Why not add inductive biases then and make your life easier? What's with this choice to try and do everything the hard way, presumably to make a point? In the end the point made is so specific that it translates to nothing that is usable in real problems.

See MuZero for example- sure, you can learn without being given the rules explicitly, just from the win/loss signal, but then that only works in board games and atari games, and without the chance of a snowball in hell that it will work in the real world. We're dazzled by the technical prowess, but real utility? Where is that?
