What's your opinion on modeling the world? Some people think the world is 3D, so we need to model the 3D world. Some people think that since human perception is 2D, we can just model the 2D view rather than the underlying 3D world, since we don't have enough 3D data to capture the world but we have many 2D views.
Fixed question: Thanks a lot for the feedback that human perception is not 2D. Let me rephrase the question: since all the visual data we see on computers can be represented as 2D images (indexed by time, angle, etc.), and we have many such 2D datasets, do we still need to explicitly model the underlying 3D world?
Also, there is no training data, which would be the "preferred form" of modification.

Not sure what led to that choice. I'd have expected either the U.S. & Canada to be in there, or not these.

What's that doing in the license? What's the implications of a license-listed "encouragement"?
That's malicious compliance. The AI Act is quite straightforward in this case - Tencent would need to document a summary of their training data, copyright compliance (that they're not stealing content to train their model) and explain how they do risk (model safety) management. That's it. It's really not rocket science.
I see a lot of skeptical folks here... isn't this the first such model? I remember seeing a lot of image to 3d models before, but they'd all produce absurd results in a few moments. This seems to produce really good output in comparison.
It explicitly says using a single picture. Wouldn't the world become even more expressive if multiple pictures could be added, such as in a photogrammetry scenario?
So could it actually turn around, like a full 360, and the image would stay the same? It looks super cool but the videos I saw just pan a little one way or the other
In 1995 I went to a talk on Image Processing by an Indian professor. I asked him if there were any methods for improving low resolution images, just to make them look better (I think this was in the context of TV transmissions). He said you couldn't make up information.
Well, 30 years later, you can generate a video from a photograph.

Cool, I guess… If you have tens of thousands of $ to drop on a GPU for output that’s definitely not usable in any 3D project out-of-the-box.

As well as an acceptable use policy: [1]I wonder if you could loop back the last frame of each video to extend the generated world further. Creating a kind of AI fever dream
Ideally based on FOSS models.
These clips are very short and don’t rotate the camera more than like 45 degrees. Genie3 also cheats and only rotate the camera 90 degrees.
It’s always important to pay attention to what models don’t do. And in this case it’s turn the bloody camera around.
I refuse to accept any model to be a “world model” if it can’t pass a simple “spin in place” test.
Bah hum bug.
We're about to see next gen games requiring these as minimum system requirements...
