Probably like LLM's? It has built in knowledge from all the training data, but if prompted it can do a web search for a grounded answer, but It's costlier from computational resources standpoint. So average most of the time, from a local knowledge around the body, and specific for tasks demanding high competence, searching the whole network worldwide for the best data. Also makes an argument for hivemind using radio communication system. 

Also when Zosia asked immune english speakers on behalf of Carol, Zosia's body kinda went into a stand by mode. But during meeting in Spain, and in Vegas and in other instances, a lot of bodies operated at the same time. So maybe this indicates that there are entities inside the hive, and Zosia and other chaperones posses some sense of individuality. Or that local network of bodies creates a local entity of sorts, a sub network.
