A lot of people in the comments say that the supposedly better examples in the article are still “horrible” because they can tell they’re AI and point to things that the AI did “wrong” and a human artist would do better.

That may be true if you’re working with a top of the line artist, but in my experience the average freelance designer online is significantly worse than AI. I’ve worked with dozens of budget friendly designers on Fiverr and consistently get way worse results than I’ve gotten from AI models. Will a great human designer produce better output than an AI? Maybe, but a small local event or business probably won’t have the budget to hire them or know where to find them. It’s cheaper, faster and easier to use AI to generate something that’s good enough for their purposes.

People also point out all the little flaws in the “good” examples and cite them as obvious tells that they were AI generated. I think it would be interesting to see if people could reliably distinguish between AI generated flyers and human made flyers. Sure, sometimes it’s obvious like when the AI adds those weird, cartoony people. But if the model is told not to create designs like that and stick to the styles used in the second half of the article, I expect people would have a much harder time distinguishing the human designs from the AI designs.

The biggest problem that I have with most AI posters is that they are too busy, you have to look for information instead of seeing it popping right away.

Amateurs posters of before AI didn't have this problem. White background, the important info in big letters, maybe one clipart or to. So I'm not talking about how pro artists could make a better job, but even the small local non-profit used to produce better posters. Not in the sense of "better looking", but in the sense that they were more readable.

At least the examples of this blog are more readable than what we usually see.

ereiamjh11 days ago
This is very true and after rendering 100 prompts twice for https://john.hartnup.uk/poster-prompts/ I realised that the prompts could be improved by asking for much less clutter. The best examples on there pick out one main visual subject, but many of them are too fussy.

I may do a V2 one of these days.

Clutter comes with the territory to some extent though. I was recently asked to do a real world PTA fayre poster, and the client (my wife) very firmly wanted 12+ attractions mentioned on the poster. Tombola, hook a duck, bar, BBQ, blah, blah, blah as well as date, location, sponsor, ...

To get a really clean design, you need to edit it down to the essentials. I don't know what pro designers do - convince the client to say less?

Unless the prompt says otherwise, AI will try to get a visual element in for every single word too.

Well what's better ? I have so many pictures of posters of old events or storefronts saved on my phone because they were so astronomically bad it'd have been better to not have any poster at all. Today's AI makes it look even worse but I'm hopeful that in five years we'll all live in a world generally more agreeable to look at and not "concrete with pink and yellow fluo paper smashed on top of it" like https://www.alamy.com/stock-photo/music-poster-wall.html or https://www.alamy.com/stock-photo/france-poster-wall.html?ps... because the cost of making things enjoyable with more colour and detail will have come down. Maybe we can finally go back to Art Nouveau if the cost of making it comes down!

> too busy, you have to look for information

Have you ever seen a bus schedule, or a parking sign, or a list of events at a local library or an “open hours” sign at a restaurant? Those are 99.9% unreadable, busy, and you have to look for information. And even then it’s not always clear if you got it right. And that was all before the AI.

The biggest problem in my view is: It's not editable by hand. There is no production data I could open in InDesign, Illustrator or Photoshop (Layers) and change things to my or my clients liking.

That also reminds me of AI-generated text, which is also (when done without caring) barely readable because of the useless noise mixed the relevant information that a human that proofread the text would have thrown out.

There's an amazing viral twitter thread where someone claimed a real Monet painting was an AI generated imitation, and it got an avalanche of comments from people who claimed it was an obvious fake and a poor imitation at that.

It's not tracking a real thing as much as people would like to think.

hnlmorg12 days ago
This is exactly the problem. Most of the time when people criticise the output of genAI, what they’re actually commenting on is the ethics of AI rather than the output of it. And they then attempt to use the demonstration as a proof of their point rather than forming an unbiased opinion of the output based on its own merit.

Now I’m not saying there isn’t legitimate criticisms that can be made about the ethics of AI, I’m highly concerned about the problems that AI brings too. But that’s a separate argument entirely.

It’s a little like people who are pompous about expensive wine, whisky’s, etc and then fail blind taste tests (plenty of studies there too).

Chance-Device11 days ago
Yes, I think this is exactly right. The labelling of a thing as “AI Generated” or “AI Assisted” makes the viewer perceive it as worse in quality. And they really do think it’s worse.

It’s similar to a well known finding about price: people value things that are more expensive more, and tend to think they are of higher quality. You can give people the same thing for a high price or for free and they’ll say the high priced one is amazing the free one is lacklustre.

It’s like an optical illusion driven by labelling.

kergonath11 days ago
You can see it here in the discussions for about half the stories. It gets sidetracked into people talking past each other.

The thing is, people are really bad at judging this, except for the most stereotypical cases. You have people crying wolf the moment you use "genuinely" or a dash. Different people use different criteria for their personal heuristics and the result is threads full of tedious, completely irrelevant comments from people in a crusade. People don’t seem to realise that we are very good at tricking ourselves and that a lot of the patterns we think we recognise are actually just noise.

I've seen two resdit threads where people insisted the hands were wrong, and people took photos of their hands in the same pose.

But, then, people did this for digital editing before. Insisted there were "clear signs of photoshop", from people who never opened that app.

I've worked with some of the top designers in the world. I don't think that AI will beat them (for now), but the examples in his sample page[0] beat the junk that I've seen a lot of non-top-designers do.

As he states, he isn't trying to make stuff that doesn't "look like AI did it," he just wants to introduce variety, and has proposed a disciplined way to do that.

johnnyanmac11 days ago
If people were not lazy enough to "introduce variety" to begin with, AI wouldn't have the slop reputation we know it to be today.

But any UX designer/engineer will tell you defaults are important. And on social media we're seeing a ton of "default". Which explains the disparity in reactions. "Default code" isn't bad in most contexts. "Default art" is bland by definition; pre-AI it wasn't exactly kosher to use stock art by itself either. It's designed as a placeholder.

Except we have all seen really awful human made posters long before AI. People are just upset just to be upset at this point.

Code was nosediving before AI badly.

johnnyanmac11 days ago
>People are just upset just to be upset at this point.

Despite this being a technical community we seem to be really bad at understanding scale.

A bad artist is at worst like a fee pieces of trash littered in your lawn. Bad AI art is like a dump truck tipping over into your yard. And you see 10 more dump truck coming in at 90mph. It doesn't matter if it's a recyclables truck and all the bottles are individually cleaner and more Eco friendly than candy bar wrappers. The magnitude is still overwhelming.

You can ignore a few bad artists you don't like. You can't ignore swimming through slop day in and day out. Friction in a previously smooth environment angers people, and AI creates a lot of newfound friction.

What? What are you comparing this pre-AI 2020s code to? 90s and 00s code for sure was worse.

It sure seems like, while LLMs and diffusion models won't completely eradicate the middle class, the bar has now risen significantly to actually contribute in a lot of areas.

For programmers, sure SV startups and actual software-first shops are probably only augments with LLMs and not replacing. But what % of software engineers are employed in such shops? Well, from my graduating class in CS, approximately 30% of grads all went to the same contracting shop whose business model seems to be, take the bottom 30% of each CS class, underpay the fuck out of them, bootcamp them into something vaguely usable + teach the house style of CRUD/LOB app framework, then throw them at clients. And this seems to still be a step above "offshore to barely baseline capable (or worse) body shop for extremely dubious results."

That entire bottom 50% is probably about to be eviscerated. The "offshore + pray" approach is probably going to be completely zapped, much easier to just vibe code for probably better (or at least not worse) results. And the onshore-but-cheaper contracting shops are probably going to need a lot fewer people whose main contribution is translating low-ambiguity tickets into syntactically valid java spring code.

Similarly, for artists, disney is probably not going to use AI in a way that substantially speeds them up because they won't tolerate the quality loss at all. But how many artists work for disney? And how many make anime waifus for the gacha apps? The latter of which I can only assume has already switched substantially to AI assets.

Morromist11 days ago
I'm not sure about coders but for artists I don't think a massive number were making anime waifus, but instead were making graphic designs for advertisements, publications & websites.

Currently AI is actually replacing some of these jobs. But there's kinda a hitch there - when you target me with ads or show me your company's website and it has obvious AI art I tend to think that you're either selling me something very low quality or are a scammer. If you show me the novel you've written and it has an AI art cover I assume the contents are also AI generated garbage writing. So I wonder if those jobs will really be replaced? It all depends on society's acceptance of AI art and if AI art doesn't get any better. I thought it would get to the point that I couldn't tell it was AI by now, but so far it hasn't.

I think AI waifus and porn and memes and browser based zynga type games will be a place AI is going to be accepted because nobody cared too much about the authenticity and quality of those things before either. But an advertisement selling me a car? The cover of a book on philosophy? A website that I'm going to give my credit card number to? I'm not sure about those things.

johnnyanmac11 days ago
>But how many artists work for disney?

Given their empire these days: a lot. Mostly because outside of Disney there's really not much such thing as "modern salaried artist". You work for any of Disney's 50 subsidiaries, you work at a games studio (because Disney gave up its expansion early in that medium), or you're likley freelancing/commissioning and grabbing whatever gig comes along.

I'm exaggerating, but less than I care to adnit. Disney makes up that much of "normal" full time artistry these days. And it's no secret how little respect artists have had in the US, even before AI.

>And how many make anime waifus for the gacha apps? The latter of which I can only assume has already switched substantially to AI assets.

In America? Less than you think. Asia has plenty of cheaper and more talented artists to exploit. AI adoption is interesting there because it's already such a sweatshop that you need to consider if AI really saves that much time for its cost. Larger studios are dabbling, smaller ones use sparingly.

No, North/South American slop is fully focused on the hyper-casual market. It's fueling thousands of asset flips for quick mobile games or copying indie games into Roblox/Fortnite. That's where the effort (or lack thereof) is going.

I find it kinda funny that even "smartest", most capable models often have a very hard time going beyond surface-level, top-of-mind associations, when faced with creative tasks.

Of course, a "Japanese Minimal Poster" has a sakura and a stylized flag of Japan, duh

A human designer would probably think that "Japan -> sakura" and "Japan -> Japanese flag" are way too obvious, too banal, too stereotypical, and, most importantly too boring. And then they would probably sit for a while and try to think of something fresher and less clichéd.

But AI has absolutely no problem with going with the cheesiest, most overused trope.

ereiamjh11 days ago
Author here.

Well of course Spring + Japan = Sakura. In a way the model would be faulty if it didn't reach for that cliché. That's what it's meant to do.

If you want originality, you need to supply it. AI fills the vacuum with the obvious thing.

And in a way that's a feature. If I was creating a poster myself I'd think "nah, can't use sakura it's too obvious". AI gets you past that hurdle. "Yeah, we used the cliché, it looks nice, let's move on".

This is if it's for a school fayre, village fête, etc. - brilliant originality isn't the goal. But it's nice when your poster doesn't look the same as three other posters on the same noticeboard (I have seen this).

If brilliant originality is needed, a human has to bring it. Although an LLM with the temperature turned up can offer some nice seeds.

gretch11 days ago
Personally I think if you were going to make a poster for a Japanese themed spring festival, and you did NOT include some sakura, you completely misunderstood the assignment.

Your promotional poster for a community gathering should not be subverting the western gaze on Japanese culture, or any other concept from art criticism 101.

It's supposed to get average people in your neighborhood to glance at it for 5-10 seconds and say, "cool looks like a good time"

wiether11 days ago
YMMV but my experience tells me that the more cliché something looks, the more likely it's bad/cheap.

I've never been in a cliché-looking restaurant that is actually decent.

Meanwhile, the best restaurants I know have, at best, a flag or some kind of small drawing to give a clue about their nationality, but otherwise they look like a regular local one.

sm-silversight11 days ago
Artist here. I'd rip off Kawase Hasui 100 different ways without using sakura or subverting anything.

More like 100ms or less as their visual field coincidentally sweeps over wherever the ad is posted in the physical world. In this regard, it's even more important to use something people subconsciously associate with your thing.
dreambuffer10 days ago
You just don't know what it's like to live in a place where art and culture is truly valued. Take Japan, for a relevant example. Many things in japan are given an extra small twist to aesthetically elevate them. The food looks a little prettier, their packages are just a bit neater, their technology is cute, they put little doodles on everything, aside from new-age products or architecture everything has a little bit of personal touch and care. This is because there is some tradition of taking pride in small details and not reaching for the most obvious solution.

A society that values culture is taking the extra 3 minutes to think of or look up some Japanese iconography that would make the poster a bit more interesting than a sakura even if brainless "average" people cannot figure out how it is relevant to Japan, the hope being that all of us learn and appreciate these things a bit more.

oliwarner12 days ago
That's a prompt problem.

If you named a Japanese artist or style rather than giving an adjective derived from a country, you might get something that wasn't national wank.

Yes, a human might do this step for you. A mediocre one might not.

I remember seeing a poster for Chinese New Year years ago, and someone had included the kanji for Japan on it (日本). Obviously they just wanted generic looking characters without bothering to see what they meant. I couldn't resist writing a comment on the poster about it.

It showed whoever did it had no clue about East Asia or Chinese script...

It’s not complicated - the default style signals low effort. Why should I get excited about the village fete if the organizers put in the barest minimum of effort?

But there’s another reason it drives people crazy - it’s low effort trying to present as high effort. If the sign was simple Comic Sans then it would at least be charmingly honest.

viraptor12 days ago
> Why should I get excited about the village fete if the organizers put in the barest minimum of effort?

Because there's no correlation between the ability to organise a village event and the graphic design skills. (Apart from "it's been so successful we can splash money on a design agency") Maybe someone actually liked it and thought it's enough. I've seen groups overthinking posters and it felt similar to groups at uni overthinking funny names instead of doing the work that actually mattered.

To be clear, I'm not saying those designs are good, just that most of the time the design is not the point and minimum effort above "Times New Roman 12pt" is what many people always wanted to do.

It feels particularly bad for a local arts faire. Like maybe ask one of the local artists if they could design a poster instead of defaulting to the plagiarism machine? If I saw this ai poster for a local crafts faire I’d immediately dismiss it.

The last paragraph in GP’s comment is the key. Nobody would care about a low effort poster, what they care about is the deception of pretending you put a lot of effort into the poster. It’s dishonest, and it would make me subconsciously question what else they’re being dishonest about.

I am inclined to agree. Small community organisation cannot afford to pay a professional designer. They might be lucky and have a talented volunteer, but in general its a waste of limit resources.
dasil00311 days ago
Low effort signals for recognizing effort in creation have all been scrambled. Now it's high effort just to identify real effort, not to mention most people in most cases would not have the expertise to recognize real effort anyway. I don't think this is entirely new from AI either, we already had so much media vying for attention that we could scant attend to more than a vanishing sliver of it.

Also just because someone used AI doesn't mean they didn't put in effort, so I don't think reflexive rejection of any AI smell is the answer. Sure, at work in a corporate white collar job where you have so many talentless strivers looking for any shortcut to climb the corporate ladder, raw AI smell actually is a highly valuable negative signal. But when it comes to local event organizers for example, there's a realness and human factor there that goes beyond anything a programmer or designer in a "scalable" context does with or without AI. We need to give our local humans grace, because humans are what it's all about.

Beer? The first example is about a beer festival. People go there to drink beer, not to see posters. A blank piece of paper that says 250 kinds of beers would get more excitement than any AI or handcrafted poster.

The only ones that aren't horrible manage that because they're so bland there's nothing to go wrong. Look at an example with some detail, the "Now please make one in the style of a 90s drum n bass gig flyer, with early 3D/fractal computer imagery" poster.

At the top of the page we have a deformed wireframe sphere. A wireframe sphere is stylistically appropriate, but the incorrect rendering is not. The "CGI" aesthetic requires obviously computer generated lines, which in the 90s meant accurate and regular lines.

Next we have a messed-up stellated polyhedron, and a messed-up dot pattern. These also fail for the same reason. The main 3D rendering is also obviously broken, as are many other small details.

But the biggest failure is the complete misunderstanding of the culture. 90s DnB was absolutely not about "good vibes". The smiley face logo is completely inappropriate; that's associated with late 80s/early 90s rave culture, pre-DnB era. 90s DnB was much darker and edgier in tone. The scene was almost exclusively male, and it maintained a aggressive vibe carried over from jungle.

A 90s DnB event would never advertise "bringing communities together". Audiences would be repelled by such messaging. This is despite it actually doing just that, as the scene was racially integrated in a way that mainstream music at the time was not. If there's going to be pro-social messaging on the poster it has to be there only implicitly.

Ach, idk. On average people have horrible design aesthetics, yet are now so arrogant about it, because they imagine their a newly found ability to spot design generated with AI equates to them being able to spot bad design.

No, you silly geese. What you are able to spot is somebody using AI poorly. That's not you developing taste. It's the equivalent of being able to tell something is photoshopped because somebody used a default brush poorly, or masked something poorly and then confounding using Photoshop with using Photoshop poorly.

You have absolutely no way of telling when a good designer created something entirely using AI (unless they are fine with you knowing that) and that has always been true.

tripleee11 days ago
Your message is right that you can't spot AI, but from what I've seen professionals by large aren't using AI for from-scratch design.

I do have one way of telling: my wife's a designer, and she has many artist and designer friends so I see how they work first hand. AI is largely used for edits that need to be done quickly rather than from-scratch generation.

You talk about aesthetics but that's very secondary to communicating the precise thing you want to communicate. AI just isn't there.

Again, I'm not really sure that the 'spotting AI' endeavour is always supposed to be a flex of someones own taste.

I have trouble parsing your entire comment, but you have lost me completely at 'always been true'. I don't know how many hours your 'good designer' would waste on creating only with AI something able to fool everybody 2 years ago. It would surely be too many to be practical.

jstummbillig11 days ago
Something, not anything. 2 years ago AI tools were much narrower and there were more things that you could not have done, but still plenty that was possible.

(Granted, given that you always needed some way of steering the AI and a harness around it, defining "entirely" in this context is a separate, debatable exercise)

It's the equivalent of being able to tell something is photoshopped because somebody used a default brush poorly, or masked something poorly and then confounding using Photoshop with using Photoshop poorly.

Speaking only for myself, that is absolutely accounted into my despair when I see an AI poster. Not just the fact that we're having a wide range of cultural and regional artifacts being stamped out and homogenized by the convenience of AI posters, but the fact that I'm only able to point them out right now because the public backlash is somewhat limited to the online sphere, so most people are okay with the default result it spits out. And we're one default ChatGPT/Claude "curated diversified aesthetic selector" feature away from making my current discernment completely useless.

Of course there's an argument of "if it's so good you can't tell, is there really a problem?", but here I'm responding specifically to the argument of a negative reaction to AI posters not taking the above into account.
