> what is the obvious thing I'm supposed to be getting from your ellipses?

Well, I'm unsure if it's a correct form of expression in English, but in my native language ellipses can often serve to express speaker/writer feeling of uncertainty about something or some kind of sadness/apathy/similar towards the situation being discussed. It's not about some "obvious thing you should get", sorry for misunderstanding.

> or are you just referring to hosted providers of those AI models?

Yes I am. I was not talking about BYD or Xiaomi; I think I focused too much on AI because that's the main topic in discussion here. That was my mistake and I apologize for that.

No worries, I was just confused, and in part was genuinely wondering if there was a vendor that sold xiaomis in the states because I'd buy one.

The ellipses in American English is often used as an awkward pause, or to indicate trailing off, or sometimes to indicate a sarcasm or passive aggressiveness. The last one seems to be a more modern usage. I have seen older generations use it as an almost soft question mark to indicate uncertainty, which always confused me because I assumed thy were being passive aggressive out of nowhere.
