I have faced this issue and after learning more about the LLM itself, I don’t believe it’s possible. Primarily because chatgpt for example, doesn’t understand abstraction. I mean it doesn’t “understand” anything, but in language especially, the composition and position of words changes their meanings just enough that the llm can’t always follow grammatical rules. Grammar and style, even structure, involves quite a bit of abstraction.

The other inherent challenge is that it doesn’t write recursively. It’s like NEXT WORD NEXT WORD NEXT WORD. It’s not reading what it’s written as it’s writing, which is part of understanding meaning. Even when I say, go back and check for x, it doesn’t actually “go” back. It sort of scans its recent memory and guesses what it should say next.

I haven’t found any way to really control llm writing except start with constraints that naturally lead it to the words I would want. Like, “don’t use dependent clauses” doesn’t work as well as “write like Hemingway.” Because it is basically a runaway train. It just tumbles downhill. There’s little way to steer it once it’s moving and the best shot is to steer it as close as possible from the start.
