Ah, yes. We definitely needed another bad dreams generator.

Interesting creative people will produce interesting creative output. People with no taste will produce tasteless content. The mountain of slop will grow. And some of us have no intention of publishing any output whatsoever but just find the existence of these tools fascinating and inspiring.

Interesting creative people are currently creating interesting output _without_ generative AI.

These tools are fascinating, though I can't help but feel that the main benefactor after all is said and done will be venture capitalists and tech/entertainment execs.

It saddens me. Innovations in AI 'art' generation (music, audio, photo) have been a net negative to society and are already actively harming the Internet and our media sphere. Like I said in another comment, LLMs are cool and useful, but who in the hell asked for AI art? It's good enough to fool people and break the fragile trust relationship we had with online content, but is also extremely shit and carries no meani…

How do you know they are a net negative? What's your source?

My opinion ;-)

That's what HN is for

I think something is getting lost in translation. These papers, from my quick skim (tho I did read the first one fully years ago,) seem to show that some images and to an extent video can be generated from discrete tokens, but does not show that exact images nor that any image can be. For instance, what combination of tokens must I put in to get _exactly_ Mona Lisa or starry night? (Tho these might be very well repre…

If you want to know what tokens you want to obtain _exactly_ Mona Lisa, or any other image, you take the image and put it through your image tokenizer aka encode it, and if you have the sequence of token you can decode it to an image. VQ-VAE (Vector Quantised-Variational AutoEncoder), (2017) https://arxiv.org/abs/1711.00937 The whole encoding-decoding process is reversible, and you only lose some imperceptible "detai…

Maybe I’m not able to articulate my thought well enough.

Taking an existing image and reversing the process to get the tokens that led to it then redoing that doesn’t seem the same as inserting token to get a precise novel image.

Especially since, as you said, we’d lose some details, it suggests that not all images can be perfectly described and recreated.

I suppose I’ll need to play around with some of those techniques.

It just plain isn't possible if you mean a prompt the size of what most people have been using lately, in the couple hundred character range. By sheer information theory, the number of possible interpretations of "a zoom in on a happy dog catching a frisbee" means that you can not match a particular clip out of the set with just that much text. You will need vastly more content; information about the breed, informati…

> Long term, you'll never have a coherent movie produced by stringing together a series of textual snippets because, again, that's just impossible. Why snippets? Submit a whole script the way a writer delivers a movie to a director. The (automated) director/DP/editor could maintain internal visual coherence, while the script drives the story coherence.

This almost certainly won’t work. Feel free to feed any of the hundreds of existing film scripts and test how coherent the models can be. My guess is not at all

0 stars, and no comments the last time this was posted. Maybe too good to be true?

I've ran hunyuanvideoai from their GitHub and it seems to generate realistic videos. It is a bit slow (30-60min per video clip) and requires ~50GB VRAM. I wonder how the quality compares though?

oh, and the output videos that are generated are 5sec clips at 554x960px. this is on a single A6000

There's this FinTech ad on the NYC subway right now. I can't remember the company, but the entire ad is just a picture of a guitar and some text. Anyway, the guitar is AI generated, and it's really bad. There are 5 strings, which morph into 6 at the headstock. There's a trem bar jammed under the pickguard, somehow. There's a randomly placed blob on the guitar that is supposed to be a knob/button, but clearly is not.…

> You're trying to sell me on something, why would you put so little effort into your advertising? Why would you not just...take a picture of a real guitar? Is this not evident? Because using AI is much cheaper and faster. Instead of finding the right guitar, paying for a good photographer, location, decoration, and all the associated logistics, a graphics designer can write a prompt that gets you 90% of the vision,…

I was able to find a similar public domain image in all of 5 seconds, so neither faster nor cheaper in this case.

In fact, it's not hard to imagine people using AI tools even if they're slower, more expensive, and yield worse quality results in the long run.

Every day that passes I grow fonder of Google's decision to delay or otherwise keep a lot of this under the wraps. The other day I was scrolling down on YouTube shorts and a couple videos invoked an uncanny valley response from me (I think it was a clip of an unrealistically large snake covering some hut) which was somehow fascinating and strange and captivating, and then scrolling down a few more, again I saw someth…

exactly one lab has passed the test of morals vs profit at this point, and thats deepmind, and they were thoroughly punished for it. Every value oAI has claimed to have hasn't lasted a milisecond longer than there was profit motive to break it, and even anthropic is doing military tech now.

LLMs aren’t AGI

> We’re introducing our video generation technology now to give society time to explore its possibilities and co-develop norms and safeguards that ensure it’s used responsibly as the field advances. That's an interesting way of saying "we're probably gonna miss some stuff in our safety tools, so hopefully society picks up the slack for us". :)

"to give society time to explore its possibilities and co-develop norms and safeguards"

Or, "this safety stuff is harder than we thought, we're just going to call 'tag you're it' on society"

Or,

-Oppenheimer : speaking "man, this nuclear safety stuff is hard, I'm just going to put it all out there and let society explore developing norms and safeguards".

-Society : Bombs Japan

-Oppenheimer : "No, not like that, oops".

Flashbacks to when they were cagey about releasing the GPT models because they could so easily be used for spam, and then just pretended not to see all the spam their model was making when they did release it.

If you happen to notice a Twitter spam bot claiming to be "an AI language model created by OpenAI", know that we have conducted an investigation and concluded that no you didn't. Mission accomplished!
