I’ll try to catch it up that way the issue for you guys would be more obvious. But that you are asking video tells that problems are just mine, not some global thing. My setup is quite typical, though.
But that much I know for sure. It comes from setting Always use default Language Model. When it is enabled it looks like changing a persona will expect very first created persona because of its pseudo-user. If that is disabled everything works just fine — but then everyone must remeber change LLM if used different one; in my case it mainly means alternating between two models, GPT-4o and o1.
I had bad feeling everything comes from very beginning how I handled pseudo-users when the first time LLM was changed. Because at that time visible user changed too at that was a pain UX wise. First you learn to use Bart and then it changed to NewBart, if you understand what I mean. Perhaps I handled it totally wrong back then and that is hounting me now.
But because one setting makes things harder I’m blaming it before I start a bit of a hard job by cleaning everything away and starting all from scratch again.
