I have an internal convention to not capitalise LLMs when talking about them as if they were people; so claude is not capitalised, and the internal LLM-based service agent we're building, rex, is not capitalised.

I realise this breaks the capitalisation of proper nouns; claude is a name and therefore a proper noun and therefore should be capitalised. But I like that there's a signal in here that the thing I'm talking about is not a person and so we don't capitalise the name (I realise that cities or companies or other things that we capitalise are also not people).

Digression, but then so was the entire discussion on capitalisation.
