Why do AI body type analyses vary so much, and which one is accurate?

I asked chatgpt and grok to analyse my body, and most of the time grok describes me as "soft curvy", "bottom heavy", "prominent glutes" etc but chatgpt is soo triggering lol. It'll describe my body as "average curves with medium sized glutes" and when I prompt "be brutally honest", it's straight up mean (same thing with grok). Can anyone explain why AI is so inconsistent when it comes to body analysis? Is chatgpt playing safe? Or is grok overly glazing?
