▲hi, I made this. thank you for posting.
I love clocks and I love finding the edges of what any given technology is capable of.
I've watched this for many hours and Kimi frequently gets the most accurate clock but also the least variation and is most boring. Qwen is often times the most insane and makes me laugh. Which one is "better?"
Clock drawing is widely used as a test for assessing dementia. Sometimes the LLMs fail in ways that are fairly predictable if you're familiar with CSS and typical shortcomings of LLMs, but sometimes they fail in ways that are less obvious from a technical perspective but are
exactly the same failure modes as cognitively-impaired humans.
I think you might have stumbled upon something surprisingly profound.

> Clock drawing is widely used as a test for assessing dementia
Interestingly, clocks are also an easy tell for when you're dreaming, if you're a lucid dreamer; they never work normally in dreams.
In lucid dreams there's a whole category of things like this: reading a paragraph of text, looking at a clock (digital or analog), or working any kind of technology more complex than a calculator.
For me personally, even light switches have been a huge tell in the past, so basically almost anything electrical.
I've always held the utterly unscientific position that this is because the brain only has enough GPU cycles to show you an approximation of what the dream world looks like, but to actually run a whole simulation behind the scenes would require more FLOPs than it has available. After all, the brain also needs to run the "player" threads: It's already super busy.
Stretching the analogy past the point of absurdity, this is a bit like modern video game optimizations: the mountains in the distance are just a painting on a surface, and the remote on that couch is just a messy blur of pixels when you look at it up close.
So the dreaming brain is like a very clever video game developer, I guess.

[-] My brain learned how to maintain legible text in dreams, I cannot use it in lucid dreaming anymore...
reply▲Wait, lucid dreamers need tells to know where they are?!?
reply▲Yes, that's how you enter the lucid state. You find ways to tell that you're dreaming and condition yourself to check for those while awake. Eventually you will do it inside a dream and realize that you're dreaming.
reply▲Didn't you ever watch Inception? You have to carry around a little spinning top to test which level of VM you're inside of.
reply▲Yeah. It’s very common to notice anomalies inside of a dream. But the anomalies weave into the dream and feel normal. You don’t have much agency to enter a lucid state from a pre-lucid dream.
So the idea is to develop habits called “reality checks” when you are awake. You look for the broken clock kind of anomalies that the grandparent comment mentioned. You have to be open to the possibility of dreaming, which is hard to do.
Consider this difficulty. Are you dreaming?
…
…
How much time did it take to think “no”? Or did you even take this question seriously? Maybe because you are reading a hn comment about lucid dreams, that question is interpreted as an example instead of a genuine question worth investigating, right? That’s the difficulty. Try it again.
The key is that the habit you’re developing isn’t just the check itself — it’s the thinking that you have during the check, which should lead you to investigate.
You do these checks frequently enough you end up doing it in a dream. Boom.
There’s also an aspect of identifying recurring patterns during prelucidity. That’s why it helps to keep a dream journal for your non-lucid dreams.
There are other methods too.
The first time it happened to me, it was accidental. I dreamed that I was in a college classroom but I realized that I never went to college. I was not trying to and had never lucid dreamed before, and so it was very surprising.
reply▲Plenty of folks out there know when they are dreaming just like they know when they are awake. It varies from person to person.

[-] be careful as adding consciousness to a dream means CPU cycles so you wake Up more tired, its cool for kids and teens but grown adults shouldnt explore this to avoid bad rest
reply▲Over time, with accumulated experience, all dreams are lucid from the start. Because of that they are very calm and pleasant; the dreamer is no longer reactive to what happens in the dream because they know nothing is at stake.
reply▲I met someone once who claimed that he lucid dreams almost every night by default and it is exhausting. He smokes weed at night to avoid dreaming entirely. I didn’t dig in super deep, but it sounded pretty intense!
reply▲IMO they would benefit from skipping the weed and instead continue to practice lucid dreaming. Over time they will develop their skill and will learn to simply contemplate the dream without reacting to it. It is a calming experience.

reply▲For me it’s phones… specifically dialling a number manually. No matter how carefully I dial, the number on the screen is rarely correct.
reply▲Whenever I dial a number while in a dream, the person I'm trying to call always turns out to be right next to me.
reply▲It seems that I’ve been stuck in a lucid dream for a couple of decades, no matter how carefully write text on a phone keyboard it never comes out as intended.
reply▲Tank ypu foe wriiting this
reply▲Do they look normal but just not work normally?
Maybe reality is a world of broken clocks, and they only “work” in the simulation.
Maybe explainable via the fact that these tests are part of the LLM training set?
reply▲jorgesborges19 hours ago
[-] Conceptual deficit is a great failure mode description. The inability to retrieve "meaning" about the clock -- having some understanding about its shape and function but not its intent to convey time to us -- is familiar with a lot of bad LLM output.
reply▲LLMs don't do this because they have "people with dementia draw clocks that way" in their data. They do it because they're similar enough to human minds in function that they often fail in similar ways.
An amusing pattern that dates back to "1kg of steel is heavier of course" in GPT-3.5.
How do you
know this?
Obviously, humans failing in these ways ARE in the training set. So it should definitely affect LLM output.
First: generalization. The failure modes extend to unseen tasks. That specific way to fail at "1kg of steel" sure was in the training data, but novel closed set logic puzzles couldn't have been. They display similar failures. The same "vibe-based reasoning" process of "steel has heavy vibes, feather has light vibes, thus, steel is heavier" produces other similar failures.
Second: the failures go away with capability (raw scale, reasoning training, test-time compute), on seen and unseen tasks both. Which is a strong hint that the model was truly failing, rather than being capable of doing a task but choosing to faithfully imitate a human failure instead.
I don't think the influence of human failures in the training data on the LLMs is nil, but it's not just a surface-level failure repetition behavior.

[-] .. would you mind sharing the prompt .. in a gist perhaps .

"Create HTML/CSS of an analog clock showing ${time}. Include numbers (or numerals) if you wish, and have a CSS animated second hand. Make it responsive and use a white background. Return ONLY the HTML/CSS code with no markdown formatting."
Watching this over the past few minutes, it looks like Kimi K2 generates the best clock face most consistently. I'd never heard of that model before today!
Qwen 2.5's clocks, on the other hand, look like they never make it out of the womb.
I knew of Kimi K2 because it’s the model used by Kagi to generate the AI answers when query ends with an interrogation point.
reply▲Really? They must've switched recently cause that was around before kimi came out
reply▲Yes, this is recent. Before it was other model(s), not sure which.
reply▲It's also one of the few 'recommended' models in Kagi Assistant (multi-model ChatGPT basically, available on paid plans).
reply▲I find that Kimi K2 looks the best, but i've noticed the time is often wrong!
reply▲It would be cool to also AI generate the favicon using some sort of image model.
reply▲It could be that the prompt is accidentally (or purposefully) more optimised for Kimi K2, or that Kimi K2 is better trained on this particular data. LLM's need "prompt engineers" for a reason to get the most out of a particular model.
reply▲How much engineering do prompt engineers do? Is it engineering when you add "photorealistic. correct number of fingers and teeth. High quality." to the end of a prompt?
we should call them "prompt witch doctors" or maybe "prompt alchemists".
I write quite a lot of prompts, and the closest analogy that I can think of is a shaman trying to appease the spirits.

[-] If there is ANY relationship to engineering here maybe it's like reverse engineering a bios in a clean room, were you poke away and see what happens. The missing part is the use of anything resembling the scientific method in terms of hypothesis, experiment design, observation guiding actions, etc and the deep knowledge that will allow you to understand WHY something might be happening based on the inputs.

reply▲Well if it works consistently, I don't see any problem with that. If they have a clear theory of when to add "photorealistic" and when to add "correct number of wheels on the bus" to get the output they want, it's engineering. If they don't have a (falsifiable) theory, it's probably not engineering.
Of course, the service they really provide is for businesses to feel they "do AI", and whether or not they do real engineering is as relevant as if your favorite pornstars' boobs are real or not.
>as relevant as if your favorite pornstars' boobs are real or not
This matters more than you might think.
Maybe we could keep the conversation out of the gutter.

reply▲It could be bioengineering if you add that to a clock prompt then connect it to CRISPR process for out putting DNA.
Horrifying prospect, tbh
> we should call them "prompt witch doctors" or maybe "prompt alchemists".
Oh absolutely not! Only in engineering you are allowed to get called an engineer for no apparent reason, do that in other white collar and you are behind the bars because of fraudulent claims.
I like that actually, I've spent the last year probably 60:40 between post-training and prompt engineering/witch doctoring (the two go together more than most people realize)
Some of it is engineering-like, but I've also picked up a sixth sense when modifying prompts about what parts are affecting the behavior I want to modify for certain models, and that feels very witch doctory!
The more engineering-like part is essentially trying to RE a black box model's post-training, but that goes over some people's heads so I'm happy to help keep the "it's just voodoo and guessing" narrative going instead :)
I think the coherence behind prompt engineering is not in the literal meanings of the words but finding the vocabulary used by the sources that have your solution. Ask questions like a high school math student and you get elementary words back. Ask questions in the lingo of a Linux bigot and you will get good awk scripts back. Use academic maths language and arXiv answers will be produced.
reply▲"How is engineering a real science? You just build the bridge so it doesn't fall down."
reply▲Nah.
Actual engineers have professional standards bodies and legal liability when they shirk and the bridge falls down or the plane crashes or your wiring starts on fire.
Software "engineers" are none of those things but can at least emulate the approaches and strive for reproducibility and testability. Skilled craftsman; not engineers.
Prompt "engineers" is yet another few steps down the ladder, working out mostly by feel what magic words best tickle each model, and generally with no understanding of what's actually going on under the hood. Closer to a chef coming up with new meals for a restaurant than anything resembling engineering.
The battle on the use of language around engineer has long been lost but applying it to the subjective creative exercise of writing prompts is just more job title inflation. Something doesn't need to be engineering to be a legitimate job.

[-] The battle on the use of language around engineer has long been lost
That's really the core of the issue: We're just having the age-old battle of prescriptivism vs descriptivism again. An "engineer", etymologically, is basically just "a person who comes up with stuff", one who is "ingenious". I'm tempted to say it's
you prescriptivists who are making a "battle" out of this.
subjective creative exercise of writing prompts
Implying that there are no testable results, no objective success or failure states? Come on man.
Engineers use their ingenuity. That’s it.
If physical engineers understood everything then standards would not have changed in many decades. Safety factors would be mostly unnecessary. Clearly not the case.
skeeter20209 hours ago
[-] >> Engineers use their ingenuity. That’s it.
If this was enough all novel creation would be engineering and that's clearly not true. Engineering attempts to discover & understand consistent outcomes when a myriad of variables are altered, and the boundaries where the variables exceed a model's predictive powers - then add buffer for the unknown. Manipulating prompts (and much of software development) attempts to control the model to limit the number of variables to obtain some form of useful abstraction. Physical engineering can't do this.
I think the selection of models is a bit off. Haiku instead of Sonnet for example. Kimi K2's capabilities are closer to Sonnet than to Haiku. GPT-5 might be in the non-reasoning mode, which routes to a smaller model.
reply▲I had my suspicions about the GPT-5 routing as well. When I first looked at it, the clock was by far the best; after the minute went by and everything refreshed, the next three were some of the worst of the group. I was wondering if it just hit a lucky path in routing the first time.
reply▲Goes to show the "frontier" is not really one frontier. It's a social/mathematical construct that's useful for a broad comparison, but if you have a niche task, there's no substitute for trying the different models.
reply▲Just use something like DSPy/Ax and optimize your module for any given LLM (based on sample data and metrics) and you’re mostly good. No need to manually wordsmith prompts.
reply▲It's not fair to use prompts tailored to a particular model when doing comparisons like this - one shot results that generalize across a domain demonstrate solid knowledge of the domain. You can use prompting and context hacking to get any particular model to behave pseudo-competently in almost any domain, even the tiny <1B models, for some set of questions. You could include an entire framework and model for rendering clocks and times that allowed all 9 models to perform fairly well.
This experiment, however, clearly states the goal with this prompt:
`Create HTML/CSS of an analog clock showing ${time}. Include numbers (or numerals) if you wish, and have a CSS animated second hand. Make it responsive and use a white background. Return ONLY the HTML/CSS code with no markdown formatting.`
An LLM should be able to interpret that, and should be able to perform a wide range of tasks in that same style - countdown timers, clocks, calendars, floating quote bubble cycling through list of 100 pithy quotations, etc. Individual, clearly defined elements should have complex representations in latent space that correspond to the human understanding of those elements. Tasks and operations and goals should likewise align with our understanding. Qwen 2.5 and some others clearly aren't modeling clocks very well, or maybe the html/css rendering latents are broken. If you pick a semantic axis(like analog clocks), you can run a suite of tests to demonstrate their understanding by using limited one-shot interactions.
Reasoning models can adapt on the fly, and are capable of cheating - one shots might have crappy representations for some contexts, but after a lot of repetition and refinement, as long as there's a stable, well represented proxy for quality somewhere in the semantics it understands, it can deconstruct a task to fundamentals and eventually reach high quality output.
These type of tests also allow us to identify mode collapses - you can use complex sophisticated prompting to get most image models to produce accurate analog clocks displaying any time, but in the simple one shot tests, the models tend to only be able to produce the time 10:10, and you'll get wild artifacts and distortions if you try to force any other configuration of hands.
Image models are so bad at hands that they couldn't even get clock hands right, until recently anyway. Nano banana and some other models are much better at avoiding mode collapses, and can traverse complex and sophisticated compositions smoothly. You want that same sort of semantic generalization in text generating models, so hopefully some of the techniques cross over to other modalities.
I keep hoping they'll be able to use SAE or some form of analysis on static weight distributions in order to uncover some sort of structural feature of mode collapse, with a taxonomy of different failure modes and causes, like limited data, or corrupt/poisoned data, and so on. Seems like if you had that, you could deliberately iterate on, correct issues, or generate supporting training material to offset big distortions in a model.
Qwen 2.5 is so bad it’s good. Some really insane results if you watch it for a while. Almost like it’s taking the piss.
reply▲Perhaps Qwen 2.5 should be known as Dali 2.‽
reply▲I’ve been using Kimi K2 a lot this month. Gives me Japanese->English translations at near human levels of quality, while respecting rules and context I give it in a very long, multi-page system prompt to improve fidelity of translation for a given translation target (sometimes markup tags need to be preserved, sometimes deleted, etc.). It doesn’t require a thinking step to generate this level of translation quality, making it suitable for real-time translation. It doesn’t start getting confused when I feed it a couple dozen lines of previous translation context, like certain other LLMs do… instead the translation actually improves with more context instead of degrading. It’s never refused a translation for “safety” purposes either (GPT and Gemini love to interrupt my novels and tell me certain behavior is illegal or immoral, and censor various anatomical words).
reply▲> GPT and Gemini love to interrupt my novels and tell me certain behavior is illegal or immoral, and censor various anatomical words

reply▲I'm a huge K2 fan, it has a personality that feels very distinct from other models (not syccophantic at all), and is quite smart. Also pretty good at creative writing (tho not 100% slop free).
K2 hosted on groq is pretty crazy for intellgence/second. (Low rate limits still, tho.)
my GPT-40 was 100% perfect on the first click. Since then, garbage. Gemini 2.5 perfect on the 3rd click.
reply▲Right as you said that, I checked kimi k2’s “clock” and it was just the ascii art: ¯\_(ツ)_/¯
I wonder if that is some type of fallback for errors querying the model, or k2 actually created the html/css to display that.
Qwen's clocks are highly entertaining. Like if you asked an alien "make me a clock".

reply▲When I clicked, everything was garbage except Grok and DeepSeek. kimi was the worst clock
reply▲Since the first (good) image generation models became available, I've been trying to get them to generate an image of a clock with 13 instead of the usual 12 hour divisions. I have not been successful. Usually they will just replace the "12" with a "13" and/or mess up the clock face in some other way.
I'd be interested if anyone else is successful. Share how you did it!
I've noticed that image models are particularly bad at modifying popular concepts in novel ways (way worse "generalization" than what I observe in language models).
reply▲Maybe LLMs always fail to generalize outside their data set, and it’s just less noticeable with written language.
reply▲This is it. They’re language models which predict next tokens probabilistically and a sampler picks one according to the desired ”temperature”. Any generalization outside their data set is an artifact of random sampling: happenstance and circumstance, not genuine substance.
reply▲However: do humans have that genuine substance? Is human invention and ingenuity more than trial and error, more than adaptation and application of existing knowledge? Can humans generalize outside their data set?
A yes-answer here implies belief in some sort of gnostic method of knowledge acquisition. Certainly that comes with a high burden of proof!
sophrosyne423 hours ago
[-] Yes. Humans can perform abduction, extrapolating given information to new information. LLMs cannot, they can only interpolate new data based on existing data.
reply▲Most image models are diffusion models, not LLMs, and have a bunch of other idiosyncrasies.
So I suspect it's more that lessons from diffusion image models don't carry over to text LLMs.
And the Image models which are based on multi-mode LLMs (like Nano Banana) seem to do a lot better at novel concepts.
They definitely don't
completely fail to generalise. You can easily prove that by asking them something completely novel.
Do you mean that LLMs might display a similar tendency to modify popular concepts? If so that definitely might be the case and would be fairly easy to test.
Something like "tell me the lord's prayer but it's our mother instead of our father", or maybe "write a haiku but with 5 syllables on every line"?
Let me try those ... nah ChatGPT nailed them both. Feels like it's particular to image generation.
They used to do poorly with modified riddles, but I assume those have been added to their training data now (
https://huggingface.co/datasets/marcodsn/altered-riddles ?)
Like, the response to "... The surgeon (who is male and is the boy's father) says: I can't operate on this boy! He's my son! How is this possible?" used to be "The surgeon is the boy's mother"
The response to "... At each door is a guard, each of which always lies. What question should I ask to decide which door to choose?" would be an explanation of how asking the guard what the other guard would say would tell you the opposite of which door you should go through.
Also, they're fundamentally bad at math. They can draw a clock because they've seen clocks, but going further requires some calculations they can't do.
For example, try asking Nano Banana to do something simpler, like "draw a picture of 13 circles." It likely will not work.
Generate an image of a clock face, but instead of the usual 12 hour numbering, number it with 13 hours.
Gemini, 2.5 Flash or "Nano Banana" or whatever we're calling it these days.
https://imgur.com/a/1sSeFX7A normal (ish) 12h clock. It numbered it twice, in two concentric rings. The outer ring is normal, but the inner ring numbers the 4th hour as "IIII" (fine, and a thing that clocks do) and the 8th hour as "VIIII" (wtf).
It should be pretty clear already that anything which is based (limited?) to communicating words/text can never grasp conceptual thinking.
We have yet to design a language to cover that, and it might be just a donquijotism we're all diving into.
> We have yet to design a language to cover that, and it might be just a donquijotism we're all diving into.

Ive been thinking about that a lot too. Fundamentally it's just a different way of telling the computer what to do and if it seems like telling an llm to make a program is less work than writing it yourself then either your program is extremely trivial or there are dozens of redundant programs in the training set that are nearly identical.
If you're actualy doing real work you have nothing to fear from LLMs because any prompt which is specific enough to create a given computer program is going to be comparable in terms of complexity and effort to having done it yourself.
I don’t think that’s clear at all. In fact the proficiency of LLMs at a wide variety of tasks would seem to indicate that language is a highly efficient encoding of human thought, much moreso than people used to think.

Most of them are just giving the result to the well known river crossing riddle. Some "feel" that something is off, but still have a hard time to figure out that wolf, boat and cabbage are just clouds.
Try to twist around words and phrases, at some point it might start to fail.
I tried it again yesterday with GPT. GPT-5 manages quite well too in thinking mode, but starts crackling in instant mode. 4o completely failed.
It's not that LLMs are unable to solve things like that at all, but it's really easy to find some variations that make them struggle really hard.
It really shows how LLMs work. It's all about probabilities, and not about understanding. If something looks very similar to a well known problem, the llm is having a hard time to "see" contradictions. Even if it's really easy to notice for humans.
reply▲I was able to have AI generate an image that made this, but not by diffusion/autoregressive but by having it write Python code to create the image.
ChatGPT made a nice looking clock with matplotlib that had some bugs that it had to fix (hours were counter-clockwise). Gemini made correct code one-shot, it used Pillow instead of matplotlib, but it didn't look as nice.
This is really cool. I tried to prompt gemini but every time I got
the same picture. I do not know how to share a session (like it is possible with Chatgpt) but the prompts were
If a clock had 13 hours, what would be the angle between two of these 13 hours?
Generate an image of such a clock
No, I want the clock to have 13 distinct hours, with the angle between them as you calculated above
This is the same image. There need to be 13 hour marks around the dial, evenly spaced
... And its last answer was
You are absolutely right, my apologies. It seems I made an error and generated the same image again. I will correct that immediately.
Here is an image of a clock face with 13 distinct hour marks, evenly spaced around the dial, reflecting the angle we calculated.
And the very same clock, with 12 hours, and a 13th above the 12...
This is probably my biggest problem with AI tools, having played around with them more lately.
"You're absolutely right! I made a mistake. I have now comprehensively solved this problem. Here is the corrected output: [totally incorrect output]."
None of them ever seem to have the ability to say "I cannot seem to do this" or "I am uncertain if this is correct, confidence level 25%" The only time they will give up or refuse to do something is when they are deliberately programmed to censor for often dubious "AI safety" reasons. All other times, they come back again and again with extreme confidence as they totally produce garbage output.
I agree, I see the same even in simple code where they will bend backwards apologizing and generate very similar crap.
It is like they are sometimes stuck in a local energetic minimum and will just wobble around various similar (and incorrect) answers.
What was annoying in my attempt above is that the picture was identical for every attempt
These tools 'attitude' reminds me of an eager, but incompetent intern or a poorly trained administrative assistant, who works for a powerful CEO. All sycophancy, confidence and positive energy, but not really getting much done.
reply▲The issue is the they always say "Here's the final, correct answer" before they've written the answer, so of course the LLM has no idea if it's going to be right before it starts, because it has no clue what it's going to say.
I wonder how it would do if instead it were told "Do not tell me at the start that the solution is going to be correct. Instead, tell me the solution, and at the end tell me if you think it's correct or not."
I have found that on certain logic puzzles that it simply cannot get right, it always tells me that it's going to get it quite "this last time," but if asked later it always recognizes its errors.

[-] Thanks for the tip about sharing!
No, my clock was an old style one, to be put on a shelf. But at least it had a "13" proudly right above the "12" :)
This reminds me my kids when they were in kindergarden and were bringing home their art that needed extra explanation to realize what it was. But they were very proud!
I do playing card generation and almost all struggle beyond the "6 of X"
My working theory is that they were trained really hard to generate 5 fingers on hands but their counting drops off quickly.
Weird, I never tried that, I tried all the usual tricks that usually work including swearing at the model (this scarily works surprisingly well with LLMs) and nothing. I even tried to go the opposite direction, I want a 6 hour clock.
reply▲Ah! This is so sad. The manager types won't be able to add an hour (actually, two) to the day even with AI.
reply▲From my experience they quickly fail to understand anything beyond a superficial description of the image you want.
reply▲That's just a patch to the training data.
Once companies see this starting to show up in the evals and criticisms, they'll go out of their way to fix it.
What would the "patch" be? Manually create some images of 13-hour clocks and add them to the training data? How does that solution scale?
reply▲I've been trying for the longest time and across models to generate pictures or cartoons of people with six fingers and now they won't do it. They always say they accomplished it, but the result always has 5 fingers. I hate being gaslit.
reply▲LLMs are terrible for out-of-distribution (OOD) tasks. You should use chain of thought suppression and give constaints explictly.
My prompt to Grok:
---
Follow these rules exactly:
- There are 13 hours, labeled 1–13.
- There are 13 ticks.
- The center of each number is at angle: index * (360/13)
- Do not infer anything else.
- Do not apply knowledge of normal clocks.
Use the following variables:
HOUR_COUNT = 13
ANGLE_PER_HOUR = 360 / 13 // 27.692307°
Use index i ∈ [0..12] for hour marks:
angle_i = i * ANGLE_PER_HOUR
I want html/css (single file) of a 13-hour analog clock.

I will try your prompt on chatgpt and gemini
Gemini failed miserably - a standard 12 hours clock
Same for chatgpt
And perplexity replaced 12 with 13
> Please create a highly unusual 13-hour analog clock widget, synchronized to system time, with fully animated hands that move in real time, and not 12 but 13 hour markings - each will be spaced at not 5-minute intervals, but at 4-minute-37-second intervals. This makes room for all 13 hour markings. Please pay attention to the correct alignment of the 13 numbers and the 13 hour marks, as well as the alignment of the hands on the face.
This gave me a correct clock face on Gemini- after the model spent a lot of time thinking (and kind of thrashing in a loop for a while). The functionality isn't quite right, not that it entirely makes sense in the first place, but the face - at least in terms of the hour marks - looks OK to me.[0]
[0] https://aistudio.google.com/app/prompts?state=%7B%22ids%22:%...
I'll also note that the output isn't quite right --- the top number should be 13 rather than 1!
reply▲I mean, the specification for the hour marks (angle_i) starts with a mark at angle 0. It just followed that spec. ;)
reply▲close enough, but digit at the top should be the highest, not 1 :/
reply▲That's because they literally cannot do that. Doing what you're asking requires an understanding of why the numbers on the clock face are where they are and what it would mean if there was an extra hour on the clock (ie that you would have to divide 360 by 13 to begin to understand where the numbers would go). AI models have no concept of anything that's not included in their training data. Yet people continue to anthropomorphize this technology and are surprised when it becomes obvious that it's not actually thinking.
reply▲The hope was for this understanding to emerge as the most efficient solution to the next-token prediction problem.
Put another way, it was hoped that once the dataset got rich enough, developing this understanding is actually more efficient for the neural network than memorizing the training data.
The useful question to ask, if you believe the hope is not bearing fruit, is why. Point specifically to the absent data or the flawed assumption being made.
Or more realistically, put in the creative and difficult research work required to discover the answer to that question.
It's interesting because if you asked them to write code to generate an SVG of a clock, they'd probably use a loop from 1 to 12, using sin and cos of the angle (given by the loop index over 12 times 2pi) to place the numerals. They know how to do this, and so they basically understand the process that generates a clock face. And extrapolating from that to 13 hours is trivial (for a human). So the fact that they can't do this extrapolation on their own is very odd.
reply▲I wonder if you would have more success if you painstakingly described the shape and features of a clock in great detail but never used the words clock or time or anything that might give the AI the hint that they were supposed to output something like a clock.
reply▲And this is a problem for me. I guess that it would work, but as soon as the word "clock" appears, gone is the request because a clock HAS.12.HOURS.
I use this a lot in cybersecurity when I need to do something "illegal". I am refused help, until I say that I am doing research on cybersecurity. In that case no problem.
The problem is more likely the tokenization of images than anything. These models do their absolute worst when pictures are involved, but are seemingly miraculous at generalizing with just text.
reply▲I wonder if it's because we mean different things by generalization.
For text, "generalization" is still "generate text that conforms to all the usual rules of the language". For images of 13-hour clock faces, we're explicitly asking the LLM to violate the inferred rules of the universe.
I think a good analogy would be asking an LLM to write in English, except the word "the" now means "purple". They will struggle to adhere to this prompt in a conversation.

[-] That's true, but I think humans would stumble a lot too (try reading old printed text from the 18fh cenfury where fhey used "f" insfead of t in prinf, if's a real frick fo gef frough).
However humans are pretty adept at discerning images, even ones outside the norm. I really think there is some kind of architectural block hampering transformers ability to really "see" images. For instance if you show any model a picture of a dog with 5 legs (a fifth leg photoshopped to it's belly) they all say there are only 4 legs. And will argue with you about it. Hell GPT-5 even wrote a leg detection script in python (impressive) which detected the 5 legs, and then it said the script was bugged, and modified the parameters until one of the legs wasn't detected, lol.

That's great, but I bet it can't tie it's own shoes.
And a submarine can't swim. Big deal.
reply▲No, but I can get it to do a lot of work.
It's a part of my daily tool box.
I've been struggling all week trying to get Claude Code to write code to produce visual (not the usual, verifiable, text on a terminal) output in the form of a SDL_GPU rendered scene consisting of the usual things like shaders, pipelines, buffers, textures and samplers, vertex and index data and so on, and boy it just doesn't seem to know what it's doing. Despite providing paragraphs-long, detailed prompts. Despite describing each uniform and each matrix that needs to be sent. Despite giving it extremely detailed guidance about what order things need to be done in. It would have been faster for me to just write the code myself.
When it fails a couple of times it will try to put logging in place and then confidently tell me things like "The vertex data has been sent to the renderer, therefore the output is correct!" When I suggest it take a screenshot of the output each time to verify correctness, it does, and then declares victory over an entirely incorrect screenshot. When I suggest it write unit tests, it does so, but the tests are worthless and only tests that the incorrect code it wrote is always incorrect in the same ways.
When it fails even more times, it will get into this what I like to call "intern engineer" mode where it just tries random things that I know are not going to work. And if I let it keep going, it will end up modifying the entire source tree with random "try this" crap. And each iteration, it confidently tells me: "Perfect! I have found the root cause! It is [garbage bullshit]. I have corrected it and the code is now completely working!"
These tools are cute, but they really need to go a long way before they are actually useful for anything more than trivial toy projects.
Have you tried OpenAI Codex with GPT5.1? I'm using it for similar GPU rendering stuff and it appears to do an excellent job.
reply▲Have you given using MCPs to provide documentation and examples a shot? I always have to bring in docs since I don't work in Python and TS+React (which it seems more capable at) and force it to review those in addition to any specification. e.g. Context7
reply▲Haven't looked into MCPs yet. Thanks for the suggestion!
reply▲I know this has been said many times before, but I wonder why this is such a common outcome. Maybe from negative outcomes being underrepresented in the training data? Maybe that plus being something slightly niche and complex?
The screenshot method not working is unsurprising to me, VLLMs visual reasoning is very bad with details because they (as far as I understand) do not really have access to those details, just the image embedding and maybe an OCR'd transcript.
I’m not sure if it's just me, but I've also noticed Claude becoming even more lazy. For example, I've asked it several times to fix my tests. It'll fix four or five of them, then start struggling with the next couple, and suddenly declare something like: "All done, fixed 5 out of 10 tests. I can’t fix the remaining ones", followed by a long, convoluted explanation about why that’s actually a good thing.

It's annoying but I prefer it to how Gemini gets depressed if it takes a few tries to make progress. Like, thanks for not gaslighing me, but now I'm feeling sorry for a big pile of numbers, which was not a stated goal in my prompt.
Amazing, some people are so enamored with LLMs who use them for soft outcomes, and disagree with me when I say be careful they're not perfect -- this is such a great non technical way to explain the reality I'm seeing when using on hard outcome coding/logic tasks. "Hey this test is failing", LLM deletes test, "FIXED!"
reply▲Something that struck me when I was looking at the clocks is that we
know what a clock is supposed to look and act like.
What about when we don't know what it's supposed to look like?
Lately I've been wrestling with the fact that unlike, say, a generalized linear model fit to data with some inferential theory, we don't have a theory or model for the uncertainty about LLM products. We recognize when it's off about things we know are off, but don't have a way to estimate when it's off other than to check it against reality, which is probably the exception to how it's used rather than the rule.
I need to be delicate with wording here, but this is why it's a worry that all the least intelligent people you know could be using AI.
It's why non-coders think it's doing an amazing job at software.
But it's worryingly why using it for research, where you necessarily don't know what you don't know, is going to trip up even smarter people.
Yeah it seems crazy to use LLM on any task where the output can't be easily verified.
reply▲> Yeah it seems crazy to use LLM on any task where the output can't be easily verified.
I disagree, those tasks are perfect for LLMs, since a bug you can't verify isn't a problem when vibecoding.

A nice continuation of the tradition of folk stories about supernatural entities like teapots or lamps that grant wishes and take them literally. "And that's why, kids, you should always review your AI-assisted commits."

[-] Last year I wrote a simple system using Semantic Kernel, backed by functions inside Microsoft Orleans, which for the most part was a business logic DSL processor by LLM. Your business logic was just text, and you gave it the operation as text.
Nothing could be relied upon to be deterministic, it was so funny to see it try to do operations.
Recently I re-ran it with newer models and was drastically better, especially with temperature tweaks.
I'm having a hard time believing this site is honest, especially with how ridiculous the scaling and rotation of numbers is for most of them.
I dumped his prompt into chatgpt to try it myself and it did create a very neat clock face with the numbers at the correct position+animated second hand, it just got the exact time wrong, being a few hours off.

[-] On the second minute I had the AI World Clocks site open the GPT-5 generated version displayed a perfect clock. Its clock before and every clock from it since has had very apparent issues though.
If you could get a perfect clock several times for the identical prompt in fresh contexts with the same model then it'd be a better comparison. Potentially the ChatGPT site you're using though is doing some adjustments that the API fed version isn't.
Think this is just prompt eng tbh. One shot Haiku 3.5 (
https://claude.ai/share/66c17968-485e-4d15-974b-4f6958e1e2fd) decent looking too.
Got it to work on gpt 3.5T w modified prompt (albeit not as good - https://pastebin.com/gjEVSEcJ)
`single html file, working analog clock showing current time, numbers positioned (aligned) correctly via trig calc (dynamic), all three hands, second hand ticks, 400px, clean AF aesthetic R/Greenberg Associates circa 2017. empathy, hci, define > design > implement.`
LLMs can't "look" at the rendered HTML output to see if what they generated makes sense or not. But there ought to be a way to do that right? To let the model iterate until what it generates looks right.
Currently, at work, I'm using Cursor for something that has an OpenGL visualization program. It's incredibly frustrating trying to describe bugs to the AI because it is completely blind. Like I just wanna tell it "there's no line connecting these two points but there ought to be one!" or "your polygon is obviously malformed as it is missing a bunch of points and intersects itself" but it's impossible. I end up having to make the AI add debug prints to, say, print out the position of each vertex, in order to convince it that it has a bug. Very high friction and annoying!!!
Cursor has this with their "browser" function for web dev, quite useful
You can also give it a mcp setup that it can send a screenshot to the conversation, though unsure if anyone made an easy enough "take screenshot of a specific window id" kind of mcp, so may need to be built first
I guess you could also ask it to build that mcp for you...
You can absolutely do this. In fact, with Claude Anthropic encourages you to send it screenshots. It works very well if you aren't expecting pixel-perfection.
YMMV with other models but Sonnet 4.5 is good with things like this - writing the code, "seeing" the output and then iterating on it.
I had some success providing screenshots to Cursor directly. It worked well for web UIs as well as generated graphs in Python. It makes them a bit less blind, though I feel more iterations are required.
reply▲Kinda - Hand waiving over the question of if an LLM can really "look" but you can connect Cursor to a Puppeteer MCP server which will allow it to iterate with "eyes" by using Puppeteer to screenshot it's own output. Still has issues, but it does solve really silly mistakes often simply by having this MCP available.
reply▲Claude totally can, same with ChatGPT. Upload a picture to either one of them via the app and tell it there's no line where there should be. There’s some plumbing involved to get it to work in Claude code or codex, but yes, computers can "see". If you have lm-server, there's tons of non-text models you can point your code at.
reply▲Why are Deepseek and Kimi are beating other models by so much margin? Is this to do with their specialization for this task?
reply▲Something I'm not able to wrap my head around is that Kimi K2 is the only model that produces a ticking second hand on every attempt while the rest of them are always moving continuously. What fundamental differences in model training or implementation can result in this disparity? Or was this use case programmed in K2 after the fact?
reply▲Most look like they were done by a beginner programmer on crack, but every once in a while a correct one appears.

DeepSeek and Kimi seem to have correct ones most of the time I've looked.
reply▲DeepSeek told me that it cannot generate pictures and suggested code (which is very different)
reply▲yes, and sometimes Grok.
reply▲The hour hand commonly seems off on Grok.
reply▲If they can identify which one is correct, then it's the same as always being correct, just with an expensive compute budget.
reply▲I'd say more like a blind programmer in the early stages of dementia. Able to write code, unable to form a mental image of what it would render as and can't see the final result.
reply▲Cool, and marginally informative on the current state of things. but kind of a waste of energy given everything is re-done every minute to compare. We'd probably only need a handful of each to see the meaningful differences.
reply▲It's actually quite fascinating if you watch it for 5 minutes. Some models are overall bad, but others nail it in one minute and butcher it in the next.
It's perhaps the best example I have seen of model drift driven by just small, seemingly unimportant changes to the prompt.
>
model drift driven by just small, seemingly unimportant changes to the promptWhat changes to the prompt are you referring to?
According the comment on the site, the prompt is the following:
Create HTML/CSS of an analog clock showing ${time}. Include numbers (or numerals) if you wish, and have a CSS animated second hand. Make it responsive and use a white background. Return ONLY the HTML/CSS code with no markdown formatting.
The prompt doesn't seem to change.
The time given to the model. So the difference between two generations is just somethng trivially different like: "12:35" vs 12:36"
reply▲presumably the time is replaced with the actual current time at each generation. I wonder if they are actually generated every minute or if all 6480 permutations (720 minutes in a day * 9 llms) were generated and just show on a schedule
reply▲It is really interesting to watch them for a while. QWEN keeps outputting some really abstract interpretations of a clock, KIMI is consistently very good, GPT5's results line up exactly with my experience with its code output (overly complex and never working correctly)
reply▲We can't know how much is about the prompt though and how much is just stochastic randomness in the behavior of that model on that prompt, right? I mean, even given identical prompts, even at temp 0, models don't always behave identically.... at least, as far as I know? Some of the reasons why are I think still a research question, but I think its a fact nonetheless.
reply▲Kimi seems the only reliable one which is a bit surprising, and GPT 4o is consistently better than GPT 5 which on the other hand is unfortunately not surprising at all.
reply▲I sort of assumed they cached like 30 inferences and just repeat them, but maybe I'm being too cynical.
reply▲The energy usage is minuscule.
reply▲Hmm, curious. How did you come up with that?
reply▲It's wasteful. If someone built a clock out of 47 microservices that called out to 193 APIs to check the current time, location, time zone, and preferred display format we'd rightfully criticize it for similar reasons.
In a world where Javascript and Electron are still getting (again, rightfully) skewered for inefficiency despite often exceeding the performance of many compiled languages, we should not dismiss the discussion around efficiency so easily.
Yes it is wasteful.
But I presume you light up Christmas lights in December, drive to the theater to watch a movie or fire up a campfire on holiday.
That too is "wasteful". It's not needed, other, or far more efficient ways exist to achieve the same. And in absolute numbers, far more energy intensive than running an LLM to create 9 clocks every minute. We do things to learn, have fun, be weird, make art, or just spend time.
Now, if Rolex starts building watches by running an LLM to drive its production machines or if we replace millions of wall clocks with ones that "Run an LLM every second", then sure, the waste is an actual problem.
Point I'm trying to make is that it's OK to consider or debate the energy use of LLMs compared to alternatives. But that bringing up that debate in a context where someone is creative, or having a fun time, its not, IMO. Because a lot of "fun" activities use a lot of energy, and that too isn't automatically "wasteful".
What I find amusing with this argument is that, no one ever brought power savings when e.g. used "let me google that for you" instead of giving someone the answer to their question, because we saw the utility of teaching others how to Google. But apparently we can't see the utility of measuring the oversold competence of current AI models, given sufficiently large sampling size.
reply▲Let's do some math.
60x24x30 = 40k AI calls per month per model. Let's suppose there are 1000 output tokens (might it be 10k tokens? Seems like a lot for this task). So 40m tokens per model.
The price for 1m output tokens[0] ranges from $.10 (qwen-2.5) to $60 (GPT-4). So $4/mo for the cheapest, and $2.5k/mo for the most expensive.
So this might cost several thousand dollars a month? Something smells funny. But you're right, throttling it to once an hour would achieve a similar goal and likely cost less than $100/mo (which is still more than I would spend on a project like this).

Same prompt to same model for a pretty straight forward task produces such wildly different outputs. Now, imagine how wildly different the code outputs when trying to generate two different logical functions. The casings are different, commenting is different, no semantic continuity. Now maybe if I give detailed prompts and ask it to follow, it might follow, but from my experience prompt adherence is not so great as well. I am at the stage where I just use LLMs as auto correct, rather than using it for any generation.

This is cool, interesting to see how consistent some models are (both in success and failure)
I tried gpt-oss-20b (my go-to local) and it looks ok though not very accurate. It decided to omit numbers. It also took 4500 tokens while thinking.
I'd be interested in seeing it with some more token leeway as well as comparing two or more similar prompts. like using "current time" instead of "${time}" and being more prescriptive about including numbers
In any case those clocks are all extremely inaccurate, even if AI could build a decent UI (which is not the case).
Some months ago I published this site for fun: https://timeutc.com There's a lot of code involved to make it precise to the ms, including adjusting based on network delay, frame refresh rate instead of using setTimeout and much more. If you are curious take a look at the source code.

Hopefully, the OP has this endpoint protected - https://clocks.brianmoore.com/api/clocks?time=11:19AM
i think it is cached on the minute level, responses cannot be that fast
reply▲where's opus/sonnet! very curious on that!
reply▲I wonder which model will silently be updated and suddenly start drawing clocks with Audemars-Piguet-level kind of complications.

[-] You should render it, show an image to the model and allow it to iterate. No person has to one-shot code without seeing what it looks like.
reply▲Kimi K2 is obviously the best, but gpt-5 has the most gorgeous ones when it works
reply▲What does it mean that each model is allowed 2000 tokens to generate its clock?
reply▲reply▲Thank you very much.... It was a fun game until I got to the prompt
Place a baby elephant in the green chair
I cannot unsee what I saw and it is 21:30 here so I have an hour or so to eliminate the picture from my mind or I will have nightmares.

[-] It is funny to see the performance improve across many of the models, somewhat miraculously, throughout the day today.
reply▲shahzaibmushtaq17 hours ago
[-] Interesting idea!
Why is a new clock being rendered every minute? Or AI models are evolving and improving every minute.

[-] I just realized I'm running late, it's almost -2!
More seriously, I'd love to see how the models perform the same task with a larger token allowance.
Very funny. It seems the Qwen generates the funniest outputs :)
reply▲Oh, Qwen, buddy, you sure are TRYING
reply▲Watching these gives me a strong feeling of unease. Art-wise, it is a very beautiful project.
reply▲just curious, why not the sonnet models? In my personal experience, Anthropic's Sonnet models are the best when it comes to things like this!
reply▲Try adding to the prompt that it has a PhD in Computer Science and have many methods for dealing with complexity.
This gives better results, at least for me.
Why does that give better results? Is this phenomena measurable? How would "you have a phd in computer science" change its ability to interpret prose? Every interaction with an LLM seems like superstition.
reply▲Selection of western models is weird no gpt-5.1 , opus 4.1 ( nailed it perfectly )
Something I quickly tested
reply▲reply▲Imagine if I asked you to draw as pixels and operate a clock via html or create a jpeg with a pencil and paper and have it be accurate.. I suspect your handcoded work to be off by an order of magnitutde compared
reply▲Was Claude banned from this Olympics?
reply▲Haiku is the lightweight Claude model, I'm not sure why they picked the weaker model.
reply▲This is why we need TeraWatt DCs, to generate code for world clocks every minute.
reply▲Looks like we've got a new Turing test here: "draw me a clock"
reply▲If a human had done this, these would be at a museum

[-] Is there a "draw a pelican riding a bicycle" version?
reply▲How Kımı is better than other BILLION$ companys is really fun
reply▲How do they do time without JavaScript? Is there an API I’m not aware of?
reply▲CSS animation. It's not the real time. Just a hypothetical time.
reply▲I’m imagining some must be using JS because I’m seeing (rarely…) times that are perfectly correct.
reply▲Actually you're right. If you view source, you can see `const response = await fetch(`/api/clocks?time=${encodeURIComponent(localTime)}`);`. I'm not sure how that API works, but it's definitely reading the current time using JS, then somehow embedding it in the HTML / CSS of each LLM.
reply▲It's crafted with a prompt that gives the AI the current time, then it simply refreshes every minute so the seconds start at zero correctly.
reply▲Looks like css keyframes
reply▲Qwens clocks are hilarious
reply▲I love that GPT-5 is putting the clock hands way outside the frame and just generally is a mess. Maybe we'll look back on these mistakes just like watching kids grow up and fumble basic tasks. Humorous in its own unique way.
reply▲> Maybe we'll look back on these hilarious mistakes just like watching kids grow up and fumble basic tasks.
Or regret: "why didn't we stop it when we could?"
Because a new clock is generated every minute, looks like simply changing the time by a digit causes the result to be significantly different from the previous iteration.
reply▲Seems like Will's clock drawing test in Hannibal :)
reply▲This really needs to be an xscreensaver hack.
reply▲Its cool to see them get it right .....sometimes
reply▲Grok is impressive, I should give it a shot
reply▲anyone tried opening this from mobile? not a single clock renders correctly, almost looks like a joke on LLMs
reply▲The qwen clocks are art.
reply▲GPT-5 is embarrassing itself. Kimi and DeepSeek are very consistently good. Wild that you can just download these models.
reply▲The new Turing time test
reply▲obviously they're all broken on firefox, no one uses firefox anyways
reply▲grok's looks like one of those clocks you'd find at a novelty shop
reply▲not sure about the accuracy though, although shooting in the dark
reply▲I believe that in a day or two, the companies will address this and it would be solved by them for that use case
reply▲Honestly, I think if you track the performance of each over time, since these get regenerated once in a while, you can then have a very, very useful and cohesive benchmark.
reply▲would be gr8t to also see the prompt this was done with
reply▲The ? has "Create HTML/CSS of an analog clock showing ${time}. Include numbers (or numerals) if you wish, and have a CSS animated second hand. Make it responsive and use a white background. Return ONLY the HTML/CSS code with no markdown formatting."
reply▲i wonder kwen prompt woud look like hallucination?
reply▲I love qwen, it tries so hard with its little paddle and never gets anywhere.
reply▲Lol. This is supposed to replace me at my job already?
Great experiment!
I'm reminded of the "draw a clock" test neurologists use to screen for dementia and brain damage.
reply▲Qwen 2.5 doing a surprisingly good job (as of right now).
reply▲How can Deepseek and Kimi get it right while Haiku, Gemini and GPT are making a mess?
reply▲Security-wise, this is a website that takes the straight output of AI and serves it for execution on their website.
I know, developers do the same, but at least they check it in Git to notice their mistakes. Here is an opportunity for AI to call a Google Authentication on you, or anything else.
It's wild how much the output varies for the same model for each run.
I'm not sure if this was the intent or not, but it sure highlights how unreliable LLMs are.
Oh cool, it's the schizophrenia clock-drawing test but for AI.
reply▲Ask Claude or ChatGPT to write it in Python, and you will see what they are capable of. HTML + CSS has never been the strong suit of any of these models.
reply▲Claude generates some js/css stuff even when i don't ask for it. I think Claude itself at least believes he is good at this.
reply▲Now that is actually creative.
Granted, it is not a clock - but it could be art. It looks like
a Picasso. When he was drunk. And took some LSD.
whatever model Cursor uses was telling me the date was March 12, 2023

[-] What a wonderfully visual example of the crap LLMs turn everything into. I am eagerly awaiting the collapse of the LLM bubble. JetBrains added this crap to their otherwise fine series of IDEs and now I have to keep removing randomly inserted import statements and keep fixing hallucinated names of functions suggested instead of the names of functions that I have already defined in the same file. Lack of determinism where we expect it (most of the things we do, tbh) is creating more problems than it is solving.
reply▲Why? This is diagonal to how LLM's work, and trivially solved by a minimal hybrid front/sub system.
reply▲Because, LLMs are touted to be the silver bullet of silver bullets. Built upon world's knowledge, and with the capacity to call upon updated information with agents, they are ought to rival the top programmers 3 days ago.
reply▲They might be touted like that but it seems like you don't understand how they work. The example in the article shows that the prompt is limiting the LLM by giving it access to only 2000 tokens and also saying "ONLY OUTPUT ...". This is like me asking you to solve the same problem but forcing you do de-activate half of your brain + forget any programming experience you have. It's just stupid.
reply▲> like you don't understand how they work.
I would not make such assumptions.
> The example in the article shows that the prompt is limiting the LLM by giving it access to only 2000 tokens and also saying "ONLY OUTPUT ..."
The site is pretty simple, method is pretty straightforward. If you believe this is unfair, you can always build one yourself.
> It's just stupid.
No, it's a great way of testing things within constraints.
The website is regenerating the clocks every minute. When I opened it, Gemini 2.5 was the only working one. Now, they are all broken.
Also, your example is not showing the current time.
It wouldn't be hard to tell to pick up browser time as the default start point. Just a piece of prompt.
reply▲Even Gemini Flash did really well for me[0] using two prompts - the initial query and one to fix the only error I could identify.
> Please generate an analog clock widget, synchronized to actual system time, with hands that update in real time and a second hand that ticks at least once per second. Make sure all the hour markings are visible and put some effort into making a modern, stylish clock face.
Followed by:
> Currently the hands are working perfectly but they're translated incorrectly making then uncentered. Can you ensure that each one is translated to the correct position on the clock face?

I don't think this is a serious test. It's just an art piece to contrast different LLMs taking on the same task, and against themselves since it updates every minute. One minute one of the results was really good for me and the next minute it was very, very bad.
reply▲Aren't they attempting to also display current time though? Your share is a clock starting at midnight/noon. Kimi K2 seems to be the best on each refresh.
reply▲How are they flawed?
reply▲The results are not reproducable, as evidenced by parent poster.
reply▲isn't that kind of the point of non-determinism?
reply▲No. Good nondeterministic models reproducibly generate equally desirable output - not identical output, but interchangeable.
reply▲oh I see, thank you for clarifying
reply▲Limiting the model to only use 2000 tokens while also asking it to output ONLY HTML/CSS is just stupid. It's like asking a programmer to perform the same task while removing half their brain and also forget about their programming experience. This is a stupid and meaningless benchmark.
