There is no "LLM style".

There is a "default LLM style", which is why I call it that. Or technically, one per LLM, but they seem to have converged pretty hard since they're all convergently evolving in the same environment.

It's trivial to prompt it out of that style. Word about how to do it and that you should do it has gotten around in the academic world where the incentives to not be caught are high. So I don't call it "the LLM style". But if you don't prompt for anything in particular, yes, there is a very very strong "default LLM style".

the default LLM style is corporate voice lol
