The AI intelligence model ranges from a first-grade system, which can't exchange information with humans, to an almighty God-like sixth-grade system feared by Elon Musk, which "continuously innovates and creates new knowledge, with I/O ability, knowledge mastery, and application ability that all approach infinite values as time goes on".
