The academy has been using the term “AI” for a while now for things that are much less sophisticated than the current/popular generation of media generators. I took an “Artificial Intelligence” class as part of my undergrad around the turn of the century.
It is confusing though, since sentience and intelligence are synonyms in the right context, but no AI has shown any good evidence of being a non-human sentient being.
The other suggestions are probably better, but you can technically self-host Wire (from Wire Gmbh) but I’ve never done it successfully.
