[Star Wars] it seems like Battle Droids of varying ranks and positions have varying levels of intelligence and autonomy. Are individual Droids built or just programmed this way?

Can I take the most basic infantry grunt and reprogram him to be an infantry commander? Or an AAT crewman?

Are they all built with the same functionality and then programmed afterwards, or are lower ranking Droids designed to just hold a gun and follow orders?

Higher ranked droids have more sophisticated AI and communication equipment. They receive general orders from their superiors, generate a plan to execute those orders, and transmit that to the droids under their "command." It distributes the processing power required for large scale decision making and limits the impact of a decapitation strike while keeping individual unit cost down.
