The variance he is seeing in the output is primarily the product of random chance, rather than changes in the model. Specifically this "unicorn" that he found today is likely just random chance and there was no changes in the model between yesterday and today that lead to it arising.
If he wanted to track changes in the model for real, he would have to ask multiple questions per day and try to infer some type of distribution characterization and then see if that changes over time. That is much more complex and not what he is doing.
This is just a curious experiment that doesn't mean much.
It is a fun experiment though.
Perhaps in a few months half of the generated pictures will look like unicorns, perhaps in more months they will all be unicorns but 2 or 3 will look way more detailed instead of drawn by a 4 year old, etc. We just need to wait longer for the signal to break through the noise.

Currently, what we are observing is primarily noise with very little signal.
The difference over months or years is what is interesting.
SVG can present arbitrarily complex graphics. The underlying display tech supports what ever fidelity GPT will eventually mature into.
Has GPT plateaud? Will it be stuck forever at this hilariously naive level of competence at SVG art? Will it mature into Midjourney level competence? I have no frigging clue. Since the token context is so small I imagine it will put limitations to the complexity of SVG art piece.
But I don't know. And it's fun to have a daily measure.
As a software engineer with a penchant for graphics asking GPT to draw complex graphic shapes was one of the first tests I did for it. It's extremely interesting for me to collect progress data, no matter how noisy.
I have no idea if GPT will ever mature beyond these squiggles but if it does, this track record will have at least considerable artistic value, if nothing else.
Let's think about it:
1. It has to output SVG [1] 2. It is given a text based representation of what it must draw[2] 3. It must then somehow convert words -- the concept of a unicorn: equine with a horn, white, maybe rainbows? -- into SVG code, and attempt to convey both their location, shape, colour, appearance, with code.
And keep in mind, this is just a token predictor. I doubt there is much data in its training that is this specific.
So while it's quite far from science, for me, it's a bit of fun and I get emails every now and then remarking on things like the turd of May (2023-05-18) and it lightens the mood every now and then, which I think ultimately, is worth it.
[1] System: You are a helpful assistant that generates SVG drawings. You respond only with SVG. You do not respond with text.
[2] User: Draw a unicorn in SVG format. Dimensions: 500x500. Respond ONLY with a single SVG string. Do not respond with conversation or codeblocks.
See: https://github.com/adamkdean/gpt-unicorn/blob/master/src/lib...
That's one the reasons why GPT when it works, feels magical. SVG art does not need to be in it's training set, as long as it knows how to present geometric concepts in SVG.
A good unicorn would require capabilities something like "the outline of unicorn is composed of lines {...}." -> "export lines as svg".
"As mentioned in the hacker news discussion, the model doesn't change daily. [...] As OpenAI releases incremental updates, we'll see the model change automatically and be able to judge outputs. A single sample per day leads to quite different results, but that's fine I think. What I expect to see a year from now is an evolution of output. In variance: how varied are the outputs over a month?"
So yes, they could just produce 100 images with each new model release, but chose to spread those out over 1 per day instead. Is it the most scientific way to measure progress? No. Is it more fun and interesting to check back daily? Probably.

That's worse logic. How would you visualize the very large sample you would get? Even with the current 118 samples (one per day) it's already difficult to find a pattern.
Would you "average" the samples?? That would not help IMO, you would need to average the score of each image, which requires either manually doing it or finding a reliable algorithm to do it automatically, but good luck with that.
So, a sample per day which allows clearly visualizing any change in the results over months and years is a valuable thing to do and I find it hard to improve on the methodology. You just need to keep in mind that one single picture from the sample is not enough, no one is going to disagree with that... but that doesn't make it "bad logic" and it's pretty thoughtless to say so.
But maybe you could covert it to a linear monotonic measure?
You could pass it to an image recognition model and see record the degree to which it thinks it is an:
animal horse unicorn
Basically if it fails to be a unicorn, see if it is a horse and if it fails to be a horse check if it is an animal. This gives you some type of linear measure if you place these three measures along the same axis adjacently. Then you can transform each image to a floating point number and then characterize the distribution.
We don't care what another algorithm "thinks". We want to see if what it draws is humanly interpretable as a unicorn.
I appreciate all the comments around determinism, sampling, scientific method, but as I said when I posted this just after building, it really is just for fun and to see, over time, if the general mish mash of outputs become more refined without any changes to the prompt (which doesn't aid it through CoT/ToT or improving on previous attempts etc.)
This is absolutly fine and it should start showing unicorn like drawings over a longer period and potentially finetuned ones over a longer period of time when the model changes.
Huh? What "original post"? This is an experiment, today the model drew something resembling a unicorn. Tomorrow we will see how the experiment goes again. I see no associated analysis, so what makes your "head hurt".
> The idea behind GPT Unicorn is quite simple: every day, GPT-4 will be asked to draw a unicorn in SVG format. This daily interaction with the model will allow us to observe changes in the model over time, as reflected in the output.
