Perhaps it's specific to present-day LLMs and things will improve in the future - but when I ask my favourite LLM to suggest creative, novel marketing options for a coffee shop it suggests a tenth-drink-free punch card. Which is pretty much the least novel answer imaginable.

It's such a banal suggestion it makes me think there could be a tension between the requirement to be creative, and the requirement that the next token be among the most probable.

I mean if that's how you're prompting it that's your problem. What are marketing options? Do you mean campaign? Campaign to do what? Increase repeat business? Get new customers? Expand into a new market?

"Hey make me a cool like marketing thing or whatever" isn't going to work.
