> It would be so easy, to generate subconcious addds with an LLM. Like weave a slogan reminder into the conversation...

Probably not without changing the underlying response and tanking the benchmark ratings. Like I ask it to generate code, it tries to add a slogan reminder, now the comments on my code have Tide's slogan in them and the variables are all named "bleach".

Probably less humorous than that, but the underlying point stands. People will be extremely upset about their prompts being tinkered with, and any perceived degradation in quality will be quickly attributed to them. The hidden nature of them will probably cause speculation that they do the same on the higher tier plans.

I think the ads would be more targeted. You ask it about code, and it suggests a paid library or an app that you can pay for.

It is quite interesting problem, because you could just respond with ok I want you to write whatever that library does. I don't want to pay for this.

If my business was a large CRUD app, like CRM I would be worried about smaller apps popping up on the market.
