Which API options in Jai do you find most effective and why?

I have been using CAI for some time, but I’m noticing that the character responses are becoming quite repetitive, as each bot tends to provide similar replies, lacking unique personalities. They also quickly forget important plot elements and overly focus on specific actions, which can be frustrating. I’ve noticed that Jai offers various APIs, so I’m curious about your preferences among them. How do you assess the quality of the AI with your chosen API? Does it effectively remember crucial details, maintain character individuality, and advance the storyline while still allowing user interaction?
