Might want a NSFW tag on this. Its not totally explicit, but not a great thing to have ones boss to walk in on either.

  Visiting the website I feel as if there's something to be learned about the current state of anime. Or maybe it's just their training data and I'm reading too much into it, dunno. The model has no idea about what arms are supposed to look like [1] but has no problem making sure that the resulting abominations are wearing underwear only. Also missing: men.

    I think it's a bit of both. There is a pretty large fanservice/borderline NSFW/smut and similar Anime industry. But there are also quite many Animes which don't have the problem or at most have a very small amount of fan service "sprinkl in". But in this generator the borderline NSFW stuff seems to be the main topic.
    - ryandrake 6y ago
      I let it run for a minute or so and every image appeared to be fully clothed or at least “bikini clothed”. Psychedelically distorted? Yes. NSFW? I guess it would depend on your W.
      - dathinab 6y ago
        I did run through it for a while. A while it indeed get's better after some time (interestingly, why does that happen?) it doesn't change that most characters are in implicit poses. Maybe clothed yes, but you can also put clothed characters in poses which imply sexual content. I also realized that the source of the images show is largely from Danbooru (with safe mode), which pretty much explains everything ;=)
        dathinab 6y ago
        Ok sometimes most characters are in implicit poses + likely in underwear/swimsuit and sometimes just some characters are in implicit poses + likely in underwear/swimsuit. It seems to be in flux.
  - Animats 6y ago
    Sometimes it gets arms right. On the rare occasions feet appear, they're totally wrong. Boobs, the system models very well. This probably reflects the training data.
    - mcphage 6y ago

    "This Rental Does Not Exist" would be useful for game world building. Fill up entire cities with plausible furnished rooms. A storefront generator would be useful. There are procedural city generators that generate blank buildings in a reasonable way, but can't fill in the details.

  I am not sure what images you get, but for me it is more wtf than porn. It gets the faces mostly right, it gets the feet sometimes right, the arms are consistently between nightmare fuel and Deadpool regrowing a lost limb.
- vmception 6y ago
  I think it's interesting because it accurately highlights what many of us males focus on. (Face+hair && breasts) || (butt && legs) With everything else and how it mashes together being an afterthought. We can patch our behavior and pretend we are looking at other things, but the GAN aggregates what all of the artists did and has an aesthetically pleasing result even when they don't make sense upon closer inspection, because it is including the features we look at.
  - Kuraj 6y ago
    You're right! I didn't think of it this way.
vmception 6y ago
Hope it learns how to include both arms more consistently
- vittore 6y ago

  Both arms... you mean less than 4? Seriously, I saw a huge number of 4-armed "creatures".
  - thesteamboat 6y ago
    It reminds me of an old article from the Journal of Irreproducible Results that posited that the missing limbs from ancient Greek statues could be found having been transplanted (somehow) to Hindu statues.

I thing they feed to many borderline NSFW picture material into the AI.
- kache_ 6y ago
  it seems that these days most anime content borders on NSFW :(
  - dathinab 6y ago
    Not necessary, but the source used for the images displayed (there are others on the website explaining what it does) has a bias in that direction which is stronger then the bias you find in e.g. Animes on crunchyroll or similar. EDIT: It also a very reasonable source as it's very hard to get large amount of anime/manga images which mostly are in color, which more importantly are tagged and you know you will most likely not get in trouble for using them.

When you look closely at the artwork, you see that almost all of them are deformed bodies. I guess this is how ML systems dream.
- rob74 6y ago
  The "deformed-ness" isn't because of the ML, anime/manga girls drawn by humans are already deformed enough (just looks at those huge eyes, if they were real you probably couldn't fit a brain in that head) - the difference is that human artists have the sensitivity required to keep their drawings from looking too weird, while the AI drives straight over the edge of the uncanny valley (or rather, creepy canyon)...
  - smegger001 6y ago
    I dont know i saw leg/arms leg on one end arm on the other detached from the body next to it there is more to the deformed anatomy then simple scale
  - vharuck 6y ago
    Human-drawn "deformities" are things like super-long legs, missing noses, or mouths so wide they look like a Muppet. This AI creates tumor-like deformities, where limbs are missing or melded together. As an example, here's an image that couldn't decide if it wanted the girl to have a large chest or a dislocated shoulder: https://thisanimedoesnotexist.ai/results/psi-0.8/seed9182.png https://thisanimedoesnotexist.ai/results/psi-0.8/seed9182.pn...
    - userbinator 6y ago
      That one also seems to have trouble deciding on hair or an extreme elf ear.
    - visarga 6y ago
      This problem is famously solved by Progressive GANs - which are trained with images of increasing size, starting from very small; it helps eliminate the deformities by learning shape at multiple scales.

I don't know much about anime, but why are so many anime women depicted in an overly sexualised manner? Didn't we want to leave this kind of sexism behind as a society? It's like watching a sexist ad from the 1950s, but worse.
- bawolff 6y ago
  I dont know much about anime, but isn't at least a portion of anime market basically porn? Women are definitely still portrayed in a sexualized manner in the porn industry, generally speaking.
  - UShouldBWorking 6y ago
    Go to the gym sometime, women portray themselves in a sexualized manner, it's not some patriarchy telling them to sexualize themselves.
- UShouldBWorking 6y ago
  Not sure what you mean about "wanting to leave it behind." If you've been out in public recently, or on instagram or Facebook this is what women are posting and dressing like more than ever. At the gym yesterday a woman was doing squats in a thong with built in leggings. People may say one thing but they have sexualized themselves more than ever, and certainly men don't seem to be complaining about the new looks.
- mst 6y ago
  "overly" is a matter of opinion. Anime is far from a male-only thing in japan and honestly most of the time if I see anime/CGI boobs on my twitter timeline it's women retweeting them. Best to just let people like what they like, and if you don't like it, let the people who do enjoy it in peace.
- Blikkentrekker 6y ago
  Mostly because that's what one encounters and instantly recognizes as “anime”. Most Japanese animation is entertainment targeting young teenagers and younger. Japan does however have a considerable adult animation market. The a.i. is not trained with any “anime”, however, but with still promotional art which is of far higher quality and clearly trained with the adult market where sexualization is, as one might expect, more common. The paradox is that the unrealistically cute “moe” designs are typically targeted at adults and adolescents and most of the children's antertainment does not look like that. Often in Japan, one speaks of four principal demographics: young males, young females, older males, and older females. — the a.i. is quite clearly entirely trained with the “older males” demographic, which should be undertood to target around 18-30 years of age, and even within that demographic it is trained almost exclusively with moe art. Most “anime” would not even be instantly recognized as such, which is why I think the term is fairly useless. — it seems when people speak of “anime” more often than not what they mean is “moe art” whether it be animated or not. This is what the average “anime” looks like: https://assets.moomin.com/uploads/2016/02/Moomin-animation-series-1969.jpg https://assets.moomin.com/uploads/2016/02/Moomin-animation-s...

  - thesteamboat 6y ago
    I'm curious, if trained with mostly English text in the images rather than Japanese, if it would produce mostly recognizable roman characters (but not necessarily words) or whether instead the characters would be largely unrecognizable.

These generated "anime" pictures look overfitted to me. It's not convincing me that it's in any way original. I bet large parts of these pictures actually do exist, and it's just mashing its memories of these pictures together, instead of actually having internalized how to draw manga pictures. Maybe the source dataset was too small, and it was not trained strictly enough, or it should have actually trained on anime stills instead of these Moe manga style drawings. The state of the art, for example that site that generates images from sentences is much more impressive to me.
- Blikkentrekker 6y ago
  At the very least it's mashing them together in such a way that about 50% of the time they form anatomically correct humans. So at the very least it is rotating and shrinking limbs in a three dimensional way and internalized that. The other 50% of the time it goes wrong, and the result is either a human that is not anatomically correct, or something that doesn't even seem to be a two-dimensional projection of three-dimensional Euclidean space.
- isoprophlex 6y ago
  Take into account that the train set is very heterogeneous compared to eg. very well lighted, centered (celebrity) faces or whatever went into thisfacedoesnotexist. From the detailed writeup: > Broadly, his StyleGAN2-ext increases the model size and disables regularizations, which are useful for restricted domains like faces but fail badly on more complex and multimodal domains.
- sillysaurusx 6y ago
  The dataset was 2.4 million images. I assure you that a ~1GB stylegan model isn’t overfitting on that. The fact that it looks overfitted is a sign that the model is legit. The interpolation videos are much more convincing. https://images-ext-2.discordapp.net/external/4Om03hvtvjDhT4culcJGlci43yYmFhCidoK_wmqiuZk/https/i.4cdn.org/a/1611088549640.gif https://images-ext-2.discordapp.net/external/4Om03hvtvjDhT4c...

There's a lot of GAN monsters here. One of the big improvements from StyleGAN->2 was the introduction of Perceptual Path Length Loss (PPL). Has the author thought about adjusting that? Additionally there is StyleGAN2-ADA (recent) which deals better with smaller datasets (I'm not sure how big this dataset is but I'm sure it isn't as big as ImageNet). I'd imagine this would help significantly because most of the monsters are having issues with the body and multiple people, so there's probably not as many samples with that feature in the dataset. I'd be interested to see what improvements these would make.

  The AI-generated characters remind me of hentaigana, which are the obsolete variant forms of kana used before 1900: they're clearly Japanese writing, but weird and basically illegible to the modern reader. https://en.wikipedia.org/wiki/Hentaigana#Gallery https://en.wikipedia.org/wiki/Hentaigana#Gallery (That's hentai as in 変体 "variant form", not hentai as in 変態 "sexual perversion".)

- sillysaurusx 6y ago
  Not far from the truth! The source dataset was 2.4 million images from Danbooru. If you go to the site, you’ll see that male characters are pretty rare. They seem to be frequent, but only because there are an ungodly number of submissions to danbooru. Think of it more like “for every male character, there are at least 10+ female characters.” And it doesn’t help that a lot of the male characters are drawn in a female style...

The ratio of ostensibly male to female characters there is more so 7:18

For those who might not realise, Anime [1] are expensive to make. Hopefully someday those top quality Anime would be cheaper to produce with the help of Machine learning and AI.

  Check the main answer on that link. It starts with: > As animated television goes, anime is actually made on the cheap.
- the_af 6y ago
  The top voted reply states: "So anime are not really that expensive to make, in terms of the usual cost of producing a professional level half-hour animated television show with top talent." Regardless, outside of videogames autogenerated content turns me off (and sometimes even in videogames, you can tell if something was handcrafted or autogenerated). If the way to make animé "survive" means removing meaningful human authorial input, then maybe it's best if it dies? Well respected sci-fi authors of all times have seen this scenario as a dystopia. I remember one short story -- was it by PKD -- where an author inputs a novel "high concept" into a computer, a second later says "wait, I have a minor correction" and the computer replies "too late, I've already written the novel and its sequels based on your concept, it's already being distributed". Surely the answer to "this requires top talent and human artistry, and this stuff costs money" cannot be "replace them all with Machine Learning", can it?
  - Blikkentrekker 6y ago
    It speaks in terms of salary of animators and actors and compares them. Of course, all salaries and in general production of almost everything is cheaper in most nations than in the U.S.A. simply because very few taxes are paid in the U.S.A., so employees receive more salary, but every product also costs more. For instance, in 2019, the average net compensation for a salaried worker in the U.S.A. was 51 916 U.S.D., with median beng 34 248 U.S.D. I found those numbers for Japan to be 39 851 U.S.D. converted, and median 62 9475 U.S.D., actually making median higher due to the top-heavy nature of U.S.A. incomes. This top-heavy nature might also be why it's not far to compare absolute star shows with each other. I, frankly, do not really understand how The Simpsons could ever take more resources to produce than anything which involves choreographed, three-dimensional fighting scenes that involves characters dazzling and jumping through buildings: https://www.youtube.com/watch?v=AbcklBCBaFs#t=1m13 https://www.youtube.com/watch?v=AbcklBCBaFs#t=1m13

If we took the base knowledge math/physics can AI/ML stumble onto the next undiscovered stuff? Somewhat tangent, like how you can conceptualize something in your brain, you could pre-load your neurons randomly to figure out some new idea. I imagine most of it would just be noise.

There's some anime I'm really into, and some that make me really uncomfortable, like Made In Abyss, that has specific sexualization of children around fetishes. As cool as this technology is, a lot of these images seem to draw on pedophillia and sexualizing children. This is an example of a "neutral" training set with results that I wouldn't want to use to represent the entire genre. I have no idea if this comment is off limits for HN. I'm surprised to see no one else voicing their discomfort with the results of this StyleGAN output.

- gwern 6y ago
  If you don't have TFRC access, this is out of the question as a hobbyist. It's >32 GPU-months. Sorry. However, you can still transfer learn this particular model with <1 GPU-month, if you have some anime or artwork dataset you want (eg a specific character). The good news is that there's been huge progress in GAN efficiency over the past few years, and we are rapidly approaching the point where ImageNet-scale datasets can be reasonably trained with 1 GPU-month or less. Worth noting in that vein are VQ-GAN https://compvis.github.io/taming-transformers/ https://compvis.github.io/taming-transformers/ and not-so-BigGAN https://arxiv.org/abs/2009.04433 https://arxiv.org/abs/2009.04433 . There's also a resurgence of VAE work which is relatively efficient: VD-VAE https://arxiv.org/abs/2011.10650#openai https://arxiv.org/abs/2011.10650#openai and NVAE https://arxiv.org/abs/2007.03898#nvidia https://arxiv.org/abs/2007.03898#nvidia ; DALL-E https://openai.com/blog/dall-e/ https://openai.com/blog/dall-e/ also appears to be surprisingly lightweight on the VAE side. So, if you feel left out, don't worry. In the near future, between the RTX GPUs and optimization and new VAE/GANs, I expect things like Danbooru2020 https://www.gwern.net/Danbooru2020 https://www.gwern.net/Danbooru2020 to be totally doable on hobbyist hardware.

Visiting the website I feel as if there's something to be learned about the current state of anime. Or maybe it's just their training data and I'm reading too much into it, dunno. The model has no idea about what arms are supposed to look like [1] but has no problem making sure that the resulting abominations are wearing underwear only. Also missing: men.

  I think it's a bit of both. There is a pretty large fanservice/borderline NSFW/smut and similar Anime industry. But there are also quite many Animes which don't have the problem or at most have a very small amount of fan service "sprinkl in". But in this generator the borderline NSFW stuff seems to be the main topic.

    I let it run for a minute or so and every image appeared to be fully clothed or at least “bikini clothed”. Psychedelically distorted? Yes. NSFW? I guess it would depend on your W.
    - dathinab 6y ago
      I did run through it for a while. A while it indeed get's better after some time (interestingly, why does that happen?) it doesn't change that most characters are in implicit poses. Maybe clothed yes, but you can also put clothed characters in poses which imply sexual content. I also realized that the source of the images show is largely from Danbooru (with safe mode), which pretty much explains everything ;=)
      - dathinab 6y ago
        Ok sometimes most characters are in implicit poses + likely in underwear/swimsuit and sometimes just some characters are in implicit poses + likely in underwear/swimsuit. It seems to be in flux.

I think it's interesting because it accurately highlights what many of us males focus on. (Face+hair && breasts) || (butt && legs) With everything else and how it mashes together being an afterthought. We can patch our behavior and pretend we are looking at other things, but the GAN aggregates what all of the artists did and has an aesthetically pleasing result even when they don't make sense upon closer inspection, because it is including the features we look at.

  Not necessary, but the source used for the images displayed (there are others on the website explaining what it does) has a bias in that direction which is stronger then the bias you find in e.g. Animes on crunchyroll or similar. EDIT: It also a very reasonable source as it's very hard to get large amount of anime/manga images which mostly are in color, which more importantly are tagged and you know you will most likely not get in trouble for using them.

When you look closely at the artwork, you see that almost all of them are deformed bodies. I guess this is how ML systems dream.

rob74 6y ago
The "deformed-ness" isn't because of the ML, anime/manga girls drawn by humans are already deformed enough (just looks at those huge eyes, if they were real you probably couldn't fit a brain in that head) - the difference is that human artists have the sensitivity required to keep their drawings from looking too weird, while the AI drives straight over the edge of the uncanny valley (or rather, creepy canyon)...

- vharuck 6y ago
  Human-drawn "deformities" are things like super-long legs, missing noses, or mouths so wide they look like a Muppet. This AI creates tumor-like deformities, where limbs are missing or melded together. As an example, here's an image that couldn't decide if it wanted the girl to have a large chest or a dislocated shoulder: https://thisanimedoesnotexist.ai/results/psi-0.8/seed9182.png https://thisanimedoesnotexist.ai/results/psi-0.8/seed9182.pn...

Not sure what you mean about "wanting to leave it behind." If you've been out in public recently, or on instagram or Facebook this is what women are posting and dressing like more than ever. At the gym yesterday a woman was doing squats in a thong with built in leggings. People may say one thing but they have sexualized themselves more than ever, and certainly men don't seem to be complaining about the new looks.
mst 6y ago
"overly" is a matter of opinion. Anime is far from a male-only thing in japan and honestly most of the time if I see anime/CGI boobs on my twitter timeline it's women retweeting them. Best to just let people like what they like, and if you don't like it, let the people who do enjoy it in peace.
Blikkentrekker 6y ago
Mostly because that's what one encounters and instantly recognizes as “anime”. Most Japanese animation is entertainment targeting young teenagers and younger. Japan does however have a considerable adult animation market. The a.i. is not trained with any “anime”, however, but with still promotional art which is of far higher quality and clearly trained with the adult market where sexualization is, as one might expect, more common. The paradox is that the unrealistically cute “moe” designs are typically targeted at adults and adolescents and most of the children's antertainment does not look like that. Often in Japan, one speaks of four principal demographics: young males, young females, older males, and older females. — the a.i. is quite clearly entirely trained with the “older males” demographic, which should be undertood to target around 18-30 years of age, and even within that demographic it is trained almost exclusively with moe art. Most “anime” would not even be instantly recognized as such, which is why I think the term is fairly useless. — it seems when people speak of “anime” more often than not what they mean is “moe art” whether it be animated or not. This is what the average “anime” looks like: https://assets.moomin.com/uploads/2016/02/Moomin-animation-series-1969.jpg https://assets.moomin.com/uploads/2016/02/Moomin-animation-s...

These generated "anime" pictures look overfitted to me. It's not convincing me that it's in any way original. I bet large parts of these pictures actually do exist, and it's just mashing its memories of these pictures together, instead of actually having internalized how to draw manga pictures. Maybe the source dataset was too small, and it was not trained strictly enough, or it should have actually trained on anime stills instead of these Moe manga style drawings. The state of the art, for example that site that generates images from sentences is much more impressive to me.

Blikkentrekker 6y ago
At the very least it's mashing them together in such a way that about 50% of the time they form anatomically correct humans. So at the very least it is rotating and shrinking limbs in a three dimensional way and internalized that. The other 50% of the time it goes wrong, and the result is either a human that is not anatomically correct, or something that doesn't even seem to be a two-dimensional projection of three-dimensional Euclidean space.

Take into account that the train set is very heterogeneous compared to eg. very well lighted, centered (celebrity) faces or whatever went into thisfacedoesnotexist.

sillysaurusx 6y ago
The dataset was 2.4 million images. I assure you that a ~1GB stylegan model isn’t overfitting on that. The fact that it looks overfitted is a sign that the model is legit.

There's a lot of GAN monsters here. One of the big improvements from StyleGAN->2 was the introduction of Perceptual Path Length Loss (PPL). Has the author thought about adjusting that? Additionally there is StyleGAN2-ADA (recent) which deals better with smaller datasets (I'm not sure how big this dataset is but I'm sure it isn't as big as ImageNet). I'd imagine this would help significantly because most of the monsters are having issues with the body and multiple people, so there's probably not as many samples with that feature in the dataset.

The ones with text are so surreal. They feel readable and yet everything is just slightly off. I can read Japanese and this feeling is very different from reading a script that I completely don't know (like Arabic or something).

The AI-generated characters remind me of hentaigana, which are the obsolete variant forms of kana used before 1900: they're clearly Japanese writing, but weird and basically illegible to the modern reader. https://en.wikipedia.org/wiki/Hentaigana#Gallery https://en.wikipedia.org/wiki/Hentaigana#Gallery (That's hentai as in 変体 "variant form", not hentai as in 変態 "sexual perversion".)

Faces mostly work. Limbs and feet are way more hit-and-miss, lots of disturbing messes. It's still intriguing, especially since I expect further improvements to the tech over time.

sillysaurusx 6y ago
Not far from the truth! The source dataset was 2.4 million images from Danbooru. If you go to the site, you’ll see that male characters are pretty rare. They seem to be frequent, but only because there are an ungodly number of submissions to danbooru. Think of it more like “for every male character, there are at least 10+ female characters.” And it doesn’t help that a lot of the male characters are drawn in a female style...

  This is the front page of Danbooru for me, as of posting: https://i.imgur.com/9eO6ZpU.png https://i.imgur.com/9eO6ZpU.png [standard warning that it might contain nudity and violence exceeding your personal threshold] It seems to me that if it truly used Danbooru, it also filtered for specific tags, which is also indicated by the art-style that it uses. The ratio of ostensibly male to female characters there is more so 7:18

For those who might not realise, Anime [1] are expensive to make. Hopefully someday those top quality Anime would be cheaper to produce with the help of Machine learning and AI. And hopefully those Japanese companies [2] hopefully take the world wide market more seriously.

Check the main answer on that link. It starts with: > As animated television goes, anime is actually made on the cheap.
the_af 6y ago
The top voted reply states: "So anime are not really that expensive to make, in terms of the usual cost of producing a professional level half-hour animated television show with top talent." Regardless, outside of videogames autogenerated content turns me off (and sometimes even in videogames, you can tell if something was handcrafted or autogenerated). If the way to make animé "survive" means removing meaningful human authorial input, then maybe it's best if it dies? Well respected sci-fi authors of all times have seen this scenario as a dystopia. I remember one short story -- was it by PKD -- where an author inputs a novel "high concept" into a computer, a second later says "wait, I have a minor correction" and the computer replies "too late, I've already written the novel and its sequels based on your concept, it's already being distributed". Surely the answer to "this requires top talent and human artistry, and this stuff costs money" cannot be "replace them all with Machine Learning", can it?
- Blikkentrekker 6y ago
  It speaks in terms of salary of animators and actors and compares them. Of course, all salaries and in general production of almost everything is cheaper in most nations than in the U.S.A. simply because very few taxes are paid in the U.S.A., so employees receive more salary, but every product also costs more. For instance, in 2019, the average net compensation for a salaried worker in the U.S.A. was 51 916 U.S.D., with median beng 34 248 U.S.D. I found those numbers for Japan to be 39 851 U.S.D. converted, and median 62 9475 U.S.D., actually making median higher due to the top-heavy nature of U.S.A. incomes. This top-heavy nature might also be why it's not far to compare absolute star shows with each other. I, frankly, do not really understand how The Simpsons could ever take more resources to produce than anything which involves choreographed, three-dimensional fighting scenes that involves characters dazzling and jumping through buildings: https://www.youtube.com/watch?v=AbcklBCBaFs#t=1m13 https://www.youtube.com/watch?v=AbcklBCBaFs#t=1m13

damn that infinite canvas is cool edit: well it's translating a div but still pretty neat This an uninformed thought but if you're extrapolating something. If we took the base knowledge math/physics can AI/ML stumble onto the next undiscovered stuff? Somewhat tangent, like how you can conceptualize something in your brain, you could pre-load your neurons randomly to figure out some new idea. I imagine most of it would just be noise.

There's some anime I'm really into, and some that make me really uncomfortable, like Made In Abyss, that has specific sexualization of children around fetishes. As cool as this technology is, a lot of these images seem to draw on pedophillia and sexualizing children. This is an example of a "neutral" training set with results that I wouldn't want to use to represent the entire genre. I have no idea if this comment is off limits for HN. I'm surprised to see no one else voicing their discomfort with the results of this StyleGAN output.

  Quite a bit of child nudity and a camera that occasionally lingers in uncomfortable places. It's not strictly pornographic, but it is nonetheless (unfortunately) popular in less scrupulous circles for reasons beyond the plot.

What kind of computer configuration does it require to train a model like this? Speaking as noob, is it possible to create models like this on your average Ryzen 5 / GTX 1060 6GB type PC? If so, how much time would it take? I feel really excited to experiment on such projects in my spare time but reading how it costs researchers hundreds and thousands of dollar don't even try.

Aeolun 6y ago
It seems this was trained for two months! There is a blog post by the author somewhere else in this thread.
gwern 6y ago
If you don't have TFRC access, this is out of the question as a hobbyist. It's >32 GPU-months. Sorry. However, you can still transfer learn this particular model with <1 GPU-month, if you have some anime or artwork dataset you want (eg a specific character). The good news is that there's been huge progress in GAN efficiency over the past few years, and we are rapidly approaching the point where ImageNet-scale datasets can be reasonably trained with 1 GPU-month or less. Worth noting in that vein are VQ-GAN https://compvis.github.io/taming-transformers/ https://compvis.github.io/taming-transformers/ and not-so-BigGAN https://arxiv.org/abs/2009.04433 https://arxiv.org/abs/2009.04433 . There's also a resurgence of VAE work which is relatively efficient: VD-VAE https://arxiv.org/abs/2011.10650#openai https://arxiv.org/abs/2011.10650#openai and NVAE https://arxiv.org/abs/2007.03898#nvidia https://arxiv.org/abs/2007.03898#nvidia ; DALL-E https://openai.com/blog/dall-e/ https://openai.com/blog/dall-e/ also appears to be surprisingly lightweight on the VAE side. So, if you feel left out, don't worry. In the near future, between the RTX GPUs and optimization and new VAE/GANs, I expect things like Danbooru2020 https://www.gwern.net/Danbooru2020 https://www.gwern.net/Danbooru2020 to be totally doable on hobbyist hardware.
