Watching an entirely generated video of someone painting is crazy.
I can't wait to play with this but I can't even imagine how expensive it must be. They're training in full resolution and can generate up to a minute of video.
Seeing how bad video generation was, I expected it would take a few more years to get to this but it seems like this is another case of "Add data & compute"(TM) where transformers prove once again they'll learn everything and be great at it
I think it's mostly the scale. Once you have a consistent user base and tons of GPUs, batching inference/training across your cluster allows you to process requests much faster and for a lower marginal cost.
