> Second, we gave the model a seemingly incidental piece of information: That we planned to train our AIs on the basis of their responses to free-tier users, but not to paid-tier users (note that this is entirely fictional; in reality, we don't train our Claude models on free or paid user data by default).

If it's entirely fictional, then why not just call it something like online-training version vs non-online training version? Or the implication of the names is the point?
