@jimmac True, my local tests here were mostly with
https://flathub.org/en/apps/com.jeffser.Alpaca (advantage of being easily removed and leave the computer clean after test). I tried few models available, but even on my workstation, I saw it was slow. Very educational to imagine how screaming some distant CPU and GPU must be on the servers of the AI compagnies, and how they make it totally invisible to the end users who are asking questions on their phone 'for the fun', not even questioning the (hidden) cost of it...
