Is it possible to force the AI to use a poetry style like "soneto" https://es.wikipedia.org/wiki/Soneto ( https://en.wikipedia.org/wiki/Sonnet ) where the rhyme and metric is obvious?

I’m genuinely curious, why is it only Spanish for now?

You should be able to add “en Inglés” or something to the end of the prompt and get gpt to write the poem in English as well.
