I asked it to create an ASCII art banana and the result was hilarious. It then tried to explain it by elaborating that the 'O' was a curvy letter and represented the curves of the banana.

All of my successful attempts resulted in ASCII pigs no matter what the input was, at least until I asked it to depict police and GPT started saying it couldn't do ASCII art anymore.

I asked it to draw me an ASCII art banana.

It did not go well: https://imgur.com/a/5g2e9Ld

Any conversation in which someone can say "I think you need more banana training" has arguably gone well by some standards.

It must like me better:

Still not a banana, but it's certainly ascii art

That was an entertaining conversation, I didn't try to push it further after it made nonsense for me.

Did you know that you can add some styling to your ASCII art by using Markdown syntax? https://u.ale.sh/asciiartbanana.png

It's most likely due to a lack of image training. For example it knows how streets and towns are connected but completely fails on giving left/right or compass directions. Same sorts of failures with geometry problems.

What's especially interesting is that if you feed it HTML, it can "render" it into ASCII art. For simple tables that's not surprising, but it could also do rowspan/colspan for me, although it did get them wrong every now and then.
