ODIN

ODIN (Operational Data Interface Network) is an Artificial Intelligence originally created by the Venturis Corporation to function as the operating Station AI of Lunar Transfer Station Tacoma, overseeing Station Tacoma alongside it's crew to ensure optimal performance of it's function as the cargo point between Earth and Luna, the location of the Venturis Zenith Lunar Resort.

Behind the Scenes
ODIN is, in some aspects, a callback to RODIN (Rapture Operational Data Interpreter Network)—nickname The Thinker—from BioShock 2: Minerva's Den, created by Steve Gaynor and Karla Zimonja who went on to form Fullbright and make Tacoma. The most obvious similarity is that ODIN's full name and acronym are extremely similar to that of The Thinker. ODIN is also voiced by Carl Lumbly; the voice of The Thinker's inventor and Minerva's Den protagonist Charles Milton Porter.

Steve Gaynor even remarked in 2015 that after The Thinker had reached the surface, the acronym would be shortened from Rapture Operational Data Interpreter Network (RODIN) to Operational Data Interpreter Network (ODIN). Originally intended to imply The Thinker played an integral role in the development of the technology behind SHODAN (Sentient Hyper-Optimized Data Access Network) from System Shock and the acronym followed with it to eventually become a part of the acronym SHODAN, this applies even more so to and was likely the origins behind ODIN.
