What is it missing? When was the last time you tried them?

Conversations for Android and gajim are fantastic XMPP clients and very modern.

That’s not how it works at all. You are talking about “thinking” models, which are just models prompting themselves.

LLMs are fancy next word predictors. It’s just returning what mathematically is the next likely word given their training set (really token since it doesn’t actually understand words).

I second XMPP. Conversations is great and its really easy to host your own prosody server.
