The distinct 'feel' a given AI model has in conversation — its tone, quirks, verbal habits, and apparent temperament — that users come to recognize and prefer or dislike independent of raw capability.

REAL-WORLD EXAMPLE

"I switched models for this project just because the model personality was way less sycophantic."
