Re: Genie: Generative Interactive Environments
#2Firstly, do these models learn a good physics grounding for nonsense actions? Like keep pressing down even when you are in the ground? Or will they phase you through the ground?
Secondly, why are all videos like half a second long? I thought video generation came much farther than this. My guess would be that the world models unravel at any length longer than that, which is (and has always been) the problem with models such as these. Minus the video generation part, we had pretty good world models for games already, see Dreamer line of work: https://danijar.com/project/dreamerv3/

#3The results seem quite bad. Compare the static image and "game" in this one example:
Static Image: https://lh3.googleusercontent.com/c0GV4hG0Xg0eqpsUS1z62v6aJ2...
"Game": https://lh5.googleusercontent.com/L_WsAa1saPmj29DSKda_fzk15y...
In the video, the character becomes a pixelated mess. In the static image, the character is clearly on rocks in the foreground, but in the "game" we see the character magically jumping from the foreground rocks to the background structure which also contains significant distortions.
The extremely short demo videos make it slightly harder to catch these obvious issues.

What is the video resolution, 64x64? And even then it becomes blurry. Seems like another Google flag-plant-y paper filled with hot air that we will never see the source code or model for because it will expose how poor its capabilities are relative to competitors.
The internal politics at these places must be exhausting. Industry research was supposed to be free from the publish or perish mindset, but it seems like it just got replaced by a different kind of need for posturing.

Author here :) Re: 1) typically no, but of course it can hallucinate just like LLMs. 2) Agreed but the key point missing is Dreamer is trained from an RL environment with action labels. Genie is trained exclusively from videos and learns an action space. This is the first version of something that is now possible and will only improve with scale.

Hey author here :) First, tough crowd, love it, always great to get feedback because we are actively working on improving the model. We are very happy to admit it is not perfect, but given not many people thought this was possible a year ago, I am quite excited to see the next step of improvement. This is like the GPT1 of foundation world models, and we have a fair few ideas in the works to speed up progress.
The resolution is 90p but we use an upsampler to make it 360p for examples on the website.

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?
Also
> This is the first version of something that is now possible and will only improve with scale.
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?

#9I've read twice the announcement and I can't tell what this is good for. Can you please dumb it down for me?
Re: Genie: Generative Interactive Environments
#10> Genie is capable of converting a variety of different prompts into interactive, playable environments that can be easily created, stepped into, and explored
If these are generating a fully interactive environments, why are all the clips ~1 second long?
Based on the first sentence in your paper, I would have expected a playable example as a demo. Or 20.
But reading a bit further into the paper, it sounds like the model needs to be actively running inference and will generate the next frame on the fly as actions are taken- is that correct?
