How many artificial neurons does Caine have?

You see, the circus was made in 1996 (i think) and in 1996 there were Norns, which were a type of AIs with 5 artificial neurons who could learn behavior and english.

These days, ChatGPT has about 175 MILLION artificial neurons, which is (i think) about 3,5 times more than a human has neurons.

Has Caine's amount of artificial neurons been updated, or does he have 5 artifical neurons or more?
