Generative AI is going to drive the marginal cost of building 3D interactive content to zero. Unironically this will unlock the metaverse, cringe as that may sound. I'm more bullish than ever on AR/VR.

I can only speak for myself, but a Metaverse consisting of infinite procedural slop sounds about as appealing as reading infinite LLM generated books, that is, not at all. "Cost to zero" implies drinking directly from the AI firehose with no human in the loop (those cost money) and entertainment produced in that manner is still dire, even in the relatively mature field of pure text generation.

I think the biggest issue with stable diffusion based approaches has always been poor compositional ability (putting stuff where you want), and compounding anatomical/spatial errors that gave the images an offputting vibe.

All these problems are trivially solvable (solved) using traditonal 3d meshes and techniques.

Not all procedurally generated things are slop, and not all slop are made via procedural generation. And popularity has nothing to do with private, subjective quality evaluations of the individual (aka, what someone calls slop might be picasso to another), but with objective, public evaluations of the product via purchases.

What is your definition of slop?

I was thinking about this, and the definition I came up with for slop is 'aspirational and highly detailed content that resolves its details in an uninteresting or nonsensical way'.

For example, an AI picture of a bush is not slop, because we don't expect much from a picture of a bush (not aspirational).

A hand-drawn picture of a knight in armor by an enthusiastic, but not very skilled artist is not slop either - it has tons of details that resolve in an interesting way, and what it lacks in details, it allows the viewers to fill in for themselves.

A 'realistic' knight generated by AI is slop - it contains no imaginative detail, and allows very little room for personal interpretation, and it's not rewarding to view.

Slop doesn't need to be AI - creatively bankrupt overproduced garbage counts as slop in my mind as well.

Can you elaborate on how any sort of backdoor could be hidden in the model weights? It's a technical possibility to hide something in the code, but that would be a bit silly since there's not that much of it here. It's not technically possible to hide a backdoor in a set of numbers that are solely used as the operands to trivial mathematical operations, so I'm very curious about what sort of hidden backdoor you think…

When you run their demo locally, there are two places that trigger a warning that the code loads the weights unsafely. To learn more about this issue, search "pytorch model load safety issues" on Google.

I'm sure there's warnings about possibly loading code alongside the weights since they distribute the weights as pickled data, but:

1. It's trivial to go look at what's being loaded.

2. Any code that's in the distributed pickled data is not weights. The GP suggests that there are backdoors hidden in the weights which is nonsensical unless the code runs eval on the weights or something similar, which would make anyone looking at the code immediately realise it was doing something dodgy.

As an example of (1), here's all the GLOBALs in the pickled code:

    GLOBAL     'collections OrderedDict'
    GLOBAL     'torch HalfStorage'
    GLOBAL     'torch._utils _rebuild_tensor_v2'
None of these could be used for anything malicious as far as I know.

Non sequitur. My sense taste or lack of it, is irrelevant.

Questions about "taste" don't matter when the average person doesn't have the craft to produce what they claim they are competent to judge especially when we're talking about such low hanging fruit as: "write a short story", "write an essay", "analyse this math problem", "draw an anatomically accurate portrait or nude figure", "paint this still life", "sketch this landscape".

Are you able to make the distinction between taste and craftsmanship?

Then after you are done signalling whatever it is you think you're signalling by vaguely gesturing at your undoubtedly superior sense of taste, perhaps we can talk like adults about what I asked?

Recently, a lot of development in this area has been in gaussian splatting and from what I have seen, the new methods are super effective. https://en.wikipedia.org/wiki/Gaussian_splatting https://www.youtube.com/watch?v=6dPBaV6M9u4

Yeah some very impressive stuff with splats going on. But I haven't seen much about going from splats to high quality 3D meshes. I've tried one or two with pretty poor results.

There have been a few papers published on the topic, but it's "early days".

Expect a lot of progress over the next couple of years.

> Take a look at the ImgnAI gallery ( https://app.imgnai.com/ ) and tell me: can you paint better and more imaginatively than that? So while I generally agree with you, I think this was a bad example to use: a lot of these are slop, with the kind of AI sheen we've come to glaze over. I'd say less than 20% are actually artistically impressive / engaging / thought-provoking.

This is a better AI gallery (I sorted all images on the site by top from this year). https://civitai.com/images There's still plenty of slop in there, and it would be a better gallery of if there was a way to filter out anime girls. But it's definitely higher than 20% interesting to me. The closest similar community of human made art is this: https://www.deviantart.com/ Although unfortunately they've decided to allow…

> There's still plenty of slop in there, and it would be a better gallery […]

Thanks for sharing your better AI gallery. It's awesome to see.

Your reply clarifies my point even better: I shared a gallery, you evaluated it and shared an even better gallery! Undoubtedly someone else will look at yours today or next year, and say, as you said, "You missed a slop! Here's a better gallery".

My point fundamentally is about basic capability of the average and even above average person. As a classically trained amateur painter, I frequently ask myself: "Can I paint a nude figure better than what you've called slop?" As I mathematician I ask: "Can I reason better than this model?"

I think you fundamentally misunderstand what people use "slop" to describe. > Most human made art is slop too. I'm assuming you're using the term "slop" to describe low-quality, unpolished works, or works where the artist has been too ambitious with their skill level. Let me put it this way: Every piece of art that is made, is a series of decisions. The artist uses their lived experience, their tastes and their value…

> here's a human-made piece that I appreciate a lot

I like your art. I'm glad you made it. What I like most is that it's fun to look at and think about which is what you say you intended. I hope I get to see more of your art.

> To this point, I don't believe there's such a thing as "bad art" (all works have something to say about the artist!).

As a classically trained oil painter, I know for sure there is bad art especially because I've made more than enough bad art for one lifetime.

Bad art begins with a lack of craftsmanship and is exemplified by a poor use of materials/media and forms, or a lack of knowledge of those forms (e.g. poor anatomical knowledge, misunderstanding the laws of perspective), or an overly literal representation of forms (a photograph is better at being literal, for example).

> Here's an example of some "slop" from the AI Art Turing Test […] But it's very clearly AI-generated. Can you figure out why?

It's only "clearly AI-generated" because we know that AI is capable of generating art. If you saw this without that context you wouldn't immediately say "AI!" Instead, you'd give it a normal critique that you'd give a student or colleague: I'd say:

- there's too much repetition of large forms.

- there's an unpleasant hierarchy of values and not enough separation of values.

- The portrait of the human is the focus of the image yet it has been lost in the other forms.

- The composition can improve with more breathing room in the foreground or background which are too busy.

- Here look at this Frazetta!

However, my rudimentary list could just as easily be turned into prompts to be used to refine the image and experiment with variations. And, perhaps you'd consider that to be a human making decisions?

I assume it's safe to ignore as model weights aren't copyrightable, probably.

you dont know what kind of backdoors are hidden in the model weights

I'm trying to think of what kind of adversarial 3D model the weights could produce. Perhaps a 3D goatse?

I mean... you can just firewall it?

you dont know which prompt activates the backdoor, how can you firewall it if you run the model in production?

Simply sanatieze the model outputs, which is the only thing that would escape running it in complete isolation.

I have tried the model, and I agree with you on the point. A product was uploaded for a test, the output catches the product quite well, but the text on the generated 3D model is unreadable.
