When ChatGPT was newer I saw a lot of posts about raps made by it, there were always this same flow. I tried to get it to make decent rhymes, but it cannot get out of the most cheesy typical rhyme scheme possible. This was 3.5, maybe 4 or other models are better. I found I could make interesting lines if I said something like “write a paragraph with as many words that rhyme with ‘taken’ as possible”, and then you could do that with a few rhymes and twist those around to make an interesting verse.
