Interesting and cool technology - but I can't seem to ignore that every high-quality AI art application is always closed, and I don't seem to buy the ethics excuse for that. The same was said for GPT, yet I see nothing but creativity coming out from its users nowadays.

That only lasts until the community copies the paper and catches up. For example the open source DALLE-2 implementation is coming along great: https://github.com/lucidrains/DALLE2-pytorch
Re:Imagen, a text-to-image diffusion model by lucidrains on Monday May 23, 2022 @08:44PM (#31486693)
Imagen actually shows some of the components in DALLE2 is unnecessary, so Imagen will end up being easier to build. I'll definitely add the dynamic thresholding trick from Imagen to DALLE2 repository though; that is a finding that should boost any DDPMs using classifier free guidance.

I don't buy the ethics but I do buy the obvious PR nightmare that would inevitably happen if journalists could play with this and immediately publish their findings of "racist imagery generated by googles AI". That's all it's about and us complaining is not going to make them change their minds.

There already is an article calling DALL E racist and it isn’t even public yet. Just imagine what horrible things the general public will get it to spit out.
Re:Imagen, a text-to-image diffusion model by hda2 on Tuesday May 24, 2022 @12:06AM (#31487862)
Then they should be honest about it. They can use all the PR lingo they want but don't flat out lie about it.

Lying about ethics or misattributing their actions to some misguided sense of "social" responsibility puts google in a far worse light in my eyes. I can't help but wonder how many skilled employees were driven off from accepting a position at google because of lies like these.

GTP-3 was an erotica virtuoso before it was gagged. There's a serious use case here in endless porn generation. Google would very much like to not be in that business.

That said, you can download Dream by Wombo from the app store and it is one of the top smartphone apps, even though it is a few generations behind state of the art.

It is a shame that such powerful AI had to arrive during an age of prudishness that makes the Victorians seem wild.
Re:Imagen, a text-to-image diffusion model by astrange on Monday May 23, 2022 @07:00PM (#31485910)
The current GPT3 on the OpenAI dashboard is perfectly capable of generating erotica or being racist even if you don’t want it to. They didn’t block it so much as put up a warning dialog when it’s acting up.

Actually, I think they made InstructGPT even better at erotica because it’s trained to be “helpful and friendly”, so in other words they made it a sub.

"Google would very much like to not be in that business."

Google is not a hobby project anymore: "don't do evil" or whatever they whittered on about back in the day.

Re:Imagen, a text-to-image diffusion model by alexb_ on Tuesday May 24, 2022 @01:26AM (#31488323)
I imagine it's viewing porn not as "evil" but as "something we should absolutely never even come close to touching or talking about and is best left as something we pretend doesn't exist so we don't get regulated out of existence"

You're aware of nothing but creativity from its users. The people using the technology unethically intentionally don't advertise that they're using it.

There's mountains of ai-generated inauthentic content that companies (including Google) have to filter out of their services. This content is used for spam, click farms, scamming, and even state propaganda operations. GPT-2 made this problem orders of magnitude worse than it used to be, and each iteration makes it harder to filter.

The industry term is (generally) "Coordinated Inauthentic Behavior" (though this includes uses of actual human content). I think Smarter Every Day did a good videos (series?) on the topic, and there are plenty of articles on the topic if you prefer that.

The AI ethics thing is just a PR larp at this point.

“Oh our tech is so dangerous and amazing it could turn the world upside down” yet we hand it to random Bluechecks on Twitter.

It’s just marketing

Re:Imagen, a text-to-image diffusion model by fragmede on Monday May 23, 2022 @09:53PM (#31487169)
You know Twitter and Google are different companies, right?
Re:Imagen, a text-to-image diffusion model by gamegoblin on Monday May 23, 2022 @10:02PM (#31487229)
The commenter was probably referring to the fact that the people who tend to get access to things like GPT3 or DALL-E 2 tend to be people with large Twitter followings (and blue checks), and that there may be a significant marketing component to this fact.
Re:Imagen, a text-to-image diffusion model by smaudet on Monday May 23, 2022 @10:32PM (#31487384)
And that's why we need to be shutting this stuff down, completely.

Someone tried to say there were ethics committees etc the other day...what a bad joke. Who checks the ethics committee is making ethical decisions?

I was told I "didn't know what" I was talking about, excuse from some over-important know-it-all who didn't know what ethics was, i.e. they don't know what they are talking about.

Thanks for the link. Doesn't appear to be very good yet, though.

Granted that's a selection bias: you likely won't hear about the cases where legit obscene output occurs. (the only notable case I've heard is the AI Dungeon incident)
Re:Imagen, a text-to-image diffusion model by toxicFork on Monday May 23, 2022 @09:06PM (#31486841)
What is the AI dungeon incident?

TL;DR generative story site creators employ human moderation after horny people inevitably use site to make gross porn; horny people using site to make regular porn justifiably freaked out

Bring your popcorn

Re:Imagen, a text-to-image diffusion model by jchw on Monday May 23, 2022 @11:59PM (#31487828)
I always felt like the AI Dungeon response is absurdly stupid. Yeah, erotic text involving minors is not exactly something you want to be associated with, but I've heard that one of their approaches to avoiding it was to ban numbers below 18. That's... not worth it.

I feel like it would've been more than reasonable for them to have taken the position that the AI might output something distasteful, and implement a filter for people who were afraid of it.

Re:Imagen, a text-to-image diffusion model by fumblebee on Monday May 23, 2022 @09:58PM (#31487203)
Another consideration here is that hosting a queryable model like this becomes expensive. I remember a couple of years ago lone developer had to take down his site which hosted a freely accessible version of GPT-2 (3?) model because the bills were running to some $20k. (Chump change for Google, but still).
Re:Imagen, a text-to-image diffusion model by Gigachad on Tuesday May 24, 2022 @12:20AM (#31487950)
I think a lot of people would be perfectly happy to pay per query to access this.
Re:Imagen, a text-to-image diffusion model by s17n on Monday May 23, 2022 @08:57PM (#31486781)
Running inference on one of these models takes like a GPU minute, so they can't just let the public use them.
Re:Imagen, a text-to-image diffusion model by throwawaaaaay17 on Monday May 23, 2022 @09:06PM (#31486846)
They can absolutely do for it if they charge the public the cost of GPU time.
Re:Imagen, a text-to-image diffusion model by yeldarb on Monday May 23, 2022 @09:52PM (#31487164)
Can't be this; Google Colab gives out tons of free GPU usage.
Re:Imagen, a text-to-image diffusion model by astrange on Tuesday May 24, 2022 @02:02AM (#31488527)
Google has a lot of GPUs, but even so Colab seems like it’s a lot cheaper than it should be. You can get some very good GPUs on the paid plan.

Ethics,racist, LGBT, bla,bla. If we talk about political correct, I really suggest you guys go somewhere else. instead of stay in hacker news. AI generated porn is better that let some people, who do not want to do the porn, doing the porn themselves.
