The use of "him" by GP is extremely unusual IMO, and I suspect is odd for anyone with English as their native language. The current convention among normal people seems to me to be to avoid pronouns other than "it" with these tools, and generally just use the name. The name is not really relevant: like, sure, in some contexts we think of ships as "she/her", and may prefer feminine names for them, but if you used e.g. "she" rather than "it" to refer to the Titanic or any other ship with a female name, this is going to cause some double-takes / disfluent comprehension in the vast majority of native speakers in most cases.

Only if you imagine e.g. some stereotypical pirate with an eyepatch slapping the hull and saying something like "Aye, but she weathered the storm, as she always does" might this feel normal. Or, maybe if you are a Redditor and trying to make it your AI boyfriend / girlfriend, you can use he/him or some other neo-pronoun, but this is currently abnormal and not the general context.

And the fact that you can make the model act as any gender again shows why choosing "him" as some default here is strange. Absent any specific context, the choice of "him" here is poorly justified.

I thought they picked it specifically because it is gender neutral, but now I double checked and apparently it's only gender neutral in French,
