Ancilla

Ancilla were the Forerunner version of our AI. As exemplified by the Monitors, the Forerunners have developed a civilization with an extremely advanced knowledge of artificial intelligence technologies. Forerunner Ancilla have managed to achieve full sentience and are highly intelligent. The manner in which Forerunner Ancilla are created is unknown, yet is probably very different from the human method of cloning the intelligence of a sentient organism. The Forerunner, Bornstellar Makes Eternal Lasting had an Ancilla in his Forerunner armour as do all Forerunners with armour.
