I don't think there is an empirical answer to the question.
I call my Mini 'base model' even though I got it with 16GB ram.
I'm thinking it means 'not Pro', 'not Max' etc., and drive and memory size has nothing to do with it.
Thanks for the response.The base model is the lowest priced configuration for a given product. For both the 14" and 16" MBP, that base configuration includes an M2 Pro, 16GB RAM, and a 512GB SSD. For an Air, that base config includes an M2, 8GB RAM, and a 256GB SSD.
It’s the one you don’t want
I have met manny people who bought the base model (car computer whatever) and wished they got higher model
I have never met a person who got a higher model and wished they got the base model
