For what it's worth, my ASUS motherboard from 2017 has their overclocking utility branded as "AI suite 3" (implying there were 2 before). I think having a buzzword to slap on products that fits the latest trend is a checkbox for whoever is marketing these, whether or not it fits any textbook definition of that term.

Asus's AI Suite has been around a lot longer than that. My 2014 Motherboard has the same software, it came on a CD with the board. it was sold as a utility for continual performance, power, and noise/airflow tuning, nothing really like AI is sold as a feature today.
