Not much is known about the wealthy business Zabrak known only by "Mister Kasleev", but he seems to be the one who created the blueprints for the droids and possibly built them himself. Despite the number, GP-103 was really the last to be created, taking traits from both GP-101, 102, and 104 to make him the ultimate droid. However, 103 would always lack a mind and free will, making the title of "ultimate" impossible. After 103 and the other units were constructed, they all had their memories wiped for security measures and placed on a cargo ship to be delivered.
