How do you pronounce it? G as in Gif or G as in jpeg? Chat-gee-pee-tee? Chat-guh-pt? Chat-Gipity?

I like to use both gee-pee-tee and the Primeagen style "chat jippity" interchangeably, depending on who I'm talking to.

Hard G in GIF as in Graphics (which is what it stands for),

Soft G in GPT as in Generative (which is what it stands for)... Simple.

You might get away with "Gippity" in some contexts.
