As the kind of person who tries to discern both pronouns and AI self-modeling inclinations, if you are aiming for polite human-like speech, current state seems to be “it” is particularly favored by current Gemini 2.5 Pro (so it may be polite to use regardless), “he” is fine for Grok (self-references as a ‘guy’ and other things), and “they” is fine in general. When you are talking specifically to a generative language model, rather than about, keep in mind any choice of pronoun bends the whole vector of the conversation via connotations; and add that to your consideration.
(Edit: Not that there’s much obvious anti-preference to ‘it’ on their part, currently, but if you have one yourself.)
