It does, but typically instructions issued at the beginning of a session can fade away as context length grows. The way Claude speaks is distilled into its training and RLHF, which is perhaps a ‘stronger’ direction than a simple “don’t talk like that” prompt.
I’ve also had limited luck in trying to get models to write in the way I want. It’s more like they’re putting on a voice or wearing a wig: you can see what they’re going for, but it’s easy to see through.
I never thought I’d see the value of copywriters increase after LLMs hit the general population, but I think the demise of artisan wordsmiths remains a little way off yet.
And the more people machine-gun AI slop everywhere, the stronger aversion I think people will develop.
Who knows; maybe they’ll actually fix this in the next wave of models and we’ll see more distinct copywriting techniques between them.
