Not the OP, but I was asking gemini about a Google subscription I had, trying to figure out whether I would lose a particular feature if I changed the subscription. I asked whether my subscription was "grandfathered" and it assured me it was not, then later on acknowledged that I was on a legacy subscription that I would not be able to go back to.

Compared to the other LLMs I've used, it seems to have system instructions that are far more adversarial to the user.

Ask for “grandmothered” for a more forgiving response
