EDIT: Nevermind, see below. I would definitely go with a LoRA though.
I have a “style guide” markdown that is pretty expansive
I run an RLHF style loop with me in the middle for all my writing now where I give a voice rant that is over expressive (aka redundant samples of concepts that I want to express clearly) in order to manage lossy compression steps
Then I will manually clean up that last 5% after a half dozen rounds
That sequence goes into the style guide to be referenced as a reasoning chain of thought to map rant > output
It’s been three years of tuning I’d suspect at this point
I have a somewhat expansive style guide, and it still reeks of Claude.
My cleanup is much closer to 40%, which still makes it worth the effort, but sometimes when speed matters, I'll apologize for the slop.
