Why not just post the prompt you used? I have access to LLMs too.
I have over 6gb of material resulting from interactions with AI. Even a micro-essay of mediocre quality requires dozens of prompts. Why post dozens and dozens of prompts if the final product is cleaner, and easier to process? I see utterly zero reason.
Edit: One of the things I learned quickly while working with LLMs, is that the quality of the user, the input, determines the quality of the output. Not everyone's input is of equal quality.
You think if he gave you the "prompt" you'd be able to produce that book?
Heck, I should put money on this. Start a competition: I give folks a prompt, and tell them to write a book about a subject with AI. I'm the sole judge of quality. Winner gets $2000. Then let's examine the variance in the entries.
In short: using AI is a skill. It's silly to pretend otherwise.
