AI settings is different for version 14 and 13.3.1, what happened?

I recently switched to Mathematica version 14. I was using Chat Notebooks and LLMs in version 13.3.1. So, to set up my settings in v 13.3.1, I head to AI settings and select the model I wanted to use (GPT4) and also some tabs to choose and install Personas and check to connect and disconnect for API connection, but now I am getting a single tab for version 14. Was the previous setting page changed? I cannot find anything in the options or documentation or the Stephen Wolfram writings blog.

AI settings version 13.3.1:

Also this one v 13.3.1:

Now on version 14 I only get:

I am curious about this, too. However, my case is slightly different. My V14 personal use licensed laptop has the AI settings page you show for V13.3.1. My V14 primary licensed desktop has the AI settings page you show for V14. Somehow, the 2 upgrades to V14 on 2 PC’s was different.

I submitted a support ticket with WRI support, but I haven’t had a response that solves the issue. The support engineer said he forwarded the issue to the developers. That was many weeks ago. My preference is to have V14 use the AI settings you show for V13.3.1.

I see I am not the only one. It is a little bit strange, I really liked the v 13.3.1 AI settings. And in both versions i used the student and trial versions

On “14.0.0 for Mac OS X ARM (64-bit) (December 13, 2023)” I see the same settings that you see on 13.1.1
