NO

Resolves to yes if in 1 month I think from my research/the technical paper the openai sora model uses a 3d prior like Gaussian splat or nerf when generating videos.

Love the banner image of Sora

bought Ṁ50 NO

From this post - "These properties emerge without any explicit inductive biases for 3D, objects, etc.—"

Inductive biases aren't openai's style, they're mostly scale maximalists.

bought Ṁ100 NO

@SorenBouma Yes, I believe this should resolve NO

lmao the generated banner for this market is amazing

sold Ṁ11 YES

@tftftftftftftftftftftftf The description of 3D consistency as an 'emerging capability' makes me think the answer might actually be NO...

bought Ṁ5 YES

Betting yes on the basis of samples like this: https://openai.com/sora?video=zen-garden-gnome which have weird but perfectly consistent camera motion. I would have expected that if it was just raw pixels, failing to produce reasonable camera motion would also cause distortions in the scene structure.

Not betting very much, because I think it's likely we don't know the answer to this question by the closing date.
