It doesn’t make sense to make battle droids hyper intelligent. They are supposed to be mass produced, why would you make them expensive?

We see that they can make hyper intelligent droids, TCW has assassin droids and commander droids.

They are clearly more expensive, since some are uniquely adorned with decorations.

Astromechs would have to be on the more intelligent side, since they handle flying, mechanic work, navigation, etc.

The average B1 droids doesn’t need much more than chatgpt.

Keep in mind each droid is not the same. This was eluded to in episode 1. The battle droids were cheap so they had a centralized controller.

TCW tv show first episode calls this out where the battle droids explicitly said “we are independent thinkers”

Actually the law states that passenger rail has priority.

It’s just unenforced so freight ignores it
