i wonder how long would it take for this technology to advance to a point where nice people from /r/freefolk would be able to remake seasons 7 and 8 of Game of Thrones to have a nice proper ending? 5 years, 10?

In a few years we'll have entire shows made exclusively by AI.

As soon as I saw the "Gnome" face option I gnew exactly what I gneeded to do: https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2... EDIT: looks like the model doesn't like Duke Nukem: https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2... Cropping out his pistol only made it worse lol: https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2... A different image works a little bit better, thoug…

This is why we do what we do lol

Say I’m a politician who gets caught on camera doing or saying something shady. Will your service do anything to prevent me from claiming the incriminating video was just faked using your technology? Maybe logging perceptual hashes of every output could prove that a video didn’t come from you?

These sort of models are probably going to end up released as publicly available weights at some point, right? Or, if it can be trained for $500k today, how much will it cost in a couple years? IMO we can’t stuff this genie back in the bottle, for better or worse. A video won’t be solid evidence of much within our lifetimes.

That's how I see it as well. Very soon, people will assume most videos are AI generated, and the burden of prove will be on people claiming videos are real. We plan to embed some kind of hash to indicate our video is AI generated, but people will be able to get around this. Google/Apple/Samsung seem to be in the best place to solve this: whenever their devices record a real video, they can generate a hash directly in HW for that video, which can be used to verify that it was actually recorded by that phone.

Also, I think it will cost around $100k to train a model at this quality level within 1-2 years. And, will only go down from there. So, the genie is out of the bag.

Hi Lina, Andrew and Sidney, this is awesome. My go-to for checking the edges of video and face identification LLMs are Personas right now -- they're rendered faces done in a painterly style, and can be really hard to parse. Here's some output: https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2... Source image from: https://personacollective.ai/persona/1610 Overall, crazy impressive compared to competing off…

I didn't know about Persona Collective - very cool!

I think the issues in your video are more related to the style of the image and the fact that she's looking sideways than the race. In our testing so far, it's done a pretty good job across races. The stylized painting aesthetic is one of the harder styles for the model to do well on. I would recommend trying with a straight on portrait (rather than profile) and shorter generations as well... it might do a bit better there.

Our model will also get better over time, but I'm glad it can already be useful to you!

Ya, it's only a matter of time until very high quality video models will be open sourced.

Tried my hardest to push this into the uncanny valley. I did, but it was pretty hard. Seems robust. https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2...

Not robust enough to work against a sketch https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2... though perhaps it rebelled against the message

We are big fans of Hedra. Do you know if they've publicly commented on their model architecture? As far as we know, our particular choice of an end-to-end diffusion + transformer is novel.

We don't know what Hedra is doing. It could be the approach EMO has taken (https://humanaigc.github.io/emote-portrait-alive/) or VASA (https://www.microsoft.com/en-us/research/project/vasa-1/) or Loopy Avatar (https://loopyavatar.github.io/) or something else.

This is amazing and another moment where I question what the future of humans will look like. So much potential for good and evil! It's insane.

thank you! it's for sure an interesting time to be alive... can't complain about it being boring

That makes sense. It isn’t reasonable to expect malicious users to helpfully set the “evil bit,” but you can at least add a little speedbump by hashing your own AI generated content (and the presence of videos that are verifiably AI generated will at least probably catch some particularly lazy/incompetent bad actors, which will destroy their credibility and also be really funny).

In the end though, the incentive and the capability lies in the hands of camera manufacturers. It is unfortunate that video from the pre-AI era have no real reason to have been made verifiable…

Anyway, recordings of politicians saying some pretty heinous things haven’t derailed some of their campaigns anyway, so maybe none of this is really worth worrying about in the first place.
