So it doesn't need 16GB to run then. Sure it will work better maybe with 16GB and 8GB of ram these days is a bit naff and have been for a few years to be honest.I am using Apple AI on my base 8gb M2 MBA with the latest version of Sequoia 18.2. Smooth as butter. Not a hitch or an issue.
I read the reason why 16GB is standard in the M4 machines is because of the way it is produced, not so much that Apple want to give people 16GB. It was that or disabling 8GB.
How much of that is true, i don't know
