I'm really loving the new chat update. I generally use the Advanced AI Chat. I start with a custom character created through the Character Generator's Persona/Chat button. (both are my own forks of the originals with some minor updates on prompt structure) I like to use multiple characters to create a story with the AI controlling characters with small inputs to help guide the narrative and keep it from going off the rails.
I've found, in this particular system at least, that if you use (REMINDER: ......) and include additional instructions on how you want it to respond, it usually will obey, and once it's responded in the appropriate manner enough times, it falls into that pattern.
It has also been really good about capturing a character's personality and keeping it consistent, as well as keeping track of character locations and activities. The previous model would get confused and think that people that were in other rooms or even great distances away were witnesses to an event.
This model seems much more instructible than the previous. I don't know if this is something that will work with the particular generator/bot that you are using. It may take some trial and error to figure out how to guide the AI to behave how you want.
