I offer 20$ for a consistently working solution for this problem.
I wanted to translate a text with literal speech into other languages.
I specifically instructed the AI to use line breaks instead of paragraphs, everytime a new character starts to speak. Like always, it says, that it will do it, but still uses the damn paragraphs.
Prompt I tried:
Translate this text from my novel into american english following the rules below:
1. maintain sentences, that are thoughts in cursive
2. convert euro measurements into imperial
3. ABSOLUTELY NO paragraphs in between sentences, except they start with someone new speaking.
Investigating the output clearly shows, that the AI sometimes does use linebreaks and sometimes paragraphs. It still uses paragraphs 90% of the time.
If I regenerate often enough, it maybe delivers the output I instructed it to generate.
