[CharacterAI] Improve AI model quality control

I've noticed yesterday, all my bots (I mean also the one I chat with but created by others) have the icon for **regenerating/swiping the greeting**! That was a feature you had to willingly enable as a creator but was set disabled as default! I saw it enabled when I start a new chat even in my own bots in which I've set it as not available, so... is it a bug or a thing now? Well about the stream of complaints on the quality of the models getting worse and worse... I think it's something unavoidable since the models are essentially trained by us users and many of us, me included, are not skilled enough to write paragraphs of good stuff like effing professionals! Many of us are not even native english spoken! The more a model is used because it's great, the more it's doomed to get ruined! It's our fault! Until they find a way to keep the initial quality high by assigning it a sort of priority over the training-by-users one, we're destinate to ruin our own cherished "toy"! 😞
