I completely agree with one caveat. It depends on his major. Assuming he is a college student or going to be one, some majors will have more demanding computer tasks. If it's a STEM discipline and you expect it to last him, I might upgrade the RAM to 24. When my daughter started college I got her the 24GB/1TB configuration a few years ago.For his use, 16GB of RAM will be more than enough.
This is true. Some of my group mates in past analytics projects were concerned that they had older hardware (both Mac and non-mac) which might be an issue with large models and AI...wasn't even an issue because most everything was hosted services so the internet connection was the biggest factor at hand. Couldn't have said it better myself the advice you suggest. That base model M4 is staggeringly powerful and shouldn't be underestimated. "Base Model" used to be a dirty word when it came to computers, that isn't the case anymore with apple siliconStay with the base model with 16 Gig. Nothing he will be doing in college for the next 4 or 5 years is going to stress the machine. Save the money that would be spent on memory on something useful. Stay with the minimum SSD size and if more storage is needed just use an external drive. AI is going to run on servers, not on laptops, especially at a college.
