It’s frozen in time, there are no updates to it..
All of these will be drawn using the same model until they push a new update, or you switch to a different GPT
But I already think they proved the point that the generation is random enough that it would be extremely difficult to track progress this way.

And when I ask it to draw Mona Lisa, I get this:

So far as I can see, the only difference is that the GitHub repo uses the API; the ones that I have were rendered using the web chat UI. Which makes me wonder if they're using the bleeding edge model for the chat.
I haven't yet gained access to the enhanced chat features with image outputs. I'm using the API with default parameters, with the gpt-4-0314 model, outputting SVG.
It's not a perfect experiment, but we'll see how it gets on over time.
