Are Giftias more intelligent than humans?
I don't think so. Giftias, however accurate description of human life they may present, they are still just an imitation of how close an Android can be to a human being.

This question can turn out to be philosophical, as we cannot discern what's the true difference between natural and artificial intelligence.

In my opinion, what Giftias can do is all thanks to programming and limited to processing and storage, that still hasn't surpassed human capabilities.
