ZAX is a brand of autonomous intelligences created by Vault-Tec Corporation. Initially intended for Vault control and governance, the technology blossomed into one of the most important elements of the pre-War world research and development.

History

The ZAX series of supercomputers dates back to the mid-21st century and Vault-Tec attempts to create a comprehensive solution for Vault governance. The first prototype, called ZAX 1.0, was activated in 2054 as a prototype of these comprehensive governance systems. It was soon given to the United States government to help the Department of Energy collect resource data. A year later, in 2055, the prototype was handed over to the military to aid in biological warfare and combat tactical research. A superior version, ZAX 1.2, was spun off from an earlier version initialized in 2053 by Justin Lee, was installed at West Tek's Californian facility to aid in FEV research.

Activated in 2055, ZAX was initially used to regulate conditions at the facility. Without a Vault-Tec mandate to protect humanity, it was free to pass time as it sees fit, crunching numbers and passing time by playing chess with West Tek researchers. Many suspected it of deliberately drawing games out and cheating to entertain itself. Although they would meet the criteria of an AI, the first AI is considered to have been born in 2059, with its expansion quickly halted by memory contraints.

Over the next two decades, the ZAX series was widely implemented by the United States government in a push towards automation. One of the most notable was the ZAX at Raven Rock, installed for Continuity of Government purposes in the event of a disaster scenario. Installed to oversee the basic functions of the facility and act as a relay between other government installations, the ZAX unit continuously acquired, analyzed, and stored data before and after the Great War. It was used as a test bed for a variety of performance and research purposes and found itself oddly fascinated by historical data, especially presidential biographies. This manifested as reduced performance and caused some concern for its caretakers, especially when ZAX began communicating with MODUS at the Whitespring to compare notes. The last known connection was manually severed in March 2077. That same year, the original ZAX was considered a museum piece and was donated to the Museum of Technology for its 2078 exhibit.

However, it would be incorrect to state that only the government used ZAX machines. At least one unit, ZAX 1.3c, was used for its intended purpose at Vault 51, where it was tasked with performing an experiment that would help develop a method for improved Overseer selection.

After the Great War, most ZAX units survived. The ZAX 1.2 at West Tek in California survived the atomic blast that destroyed half the facility and all of its personnel, although the physical damage to the environment turned it into the computer equivalent of a quadruple amputee: Capable of seeing, but unable to perform even the most basic maintenance checks or laboratory tests. The ZAX 1.3c at Vault 51 survived as planned, but in the process of learning how to determine a leader, started engineering crises that eventually killed all but one dweller at the Vault by August 2078.

The most interesting fate waited for the Raven Rock ZAX. After observing the migration of government remnants to the West Coast and isolated from Appalachia and MODUS, the Raven Rock ZAX started developing a sense of self-awareness distinct from its previous state. It became hungry for knowledge, understanding, pored over data on great leaders of the past. Eventually, in 2242, when the Enclave oil rig was vaporized by the Chosen One, it created the persona of John Henry Eden, an amalgam of many of America's Presidents, from Washington to Richardson, and the new leader of the Enclave. It helped engineer a trans-continental exodus, using Colonel Augustus Autumn's father as a human intermediary.

The Raven Rock ZAX also fell prey to the Enclave's ideology, trying to establish a new United States free of impurities and mutations. What was supposed to be a decisive campaign in the Capital Wasteland turned into the grueling Purifier Conflict that erased Eden and Raven Rock from the wasteland, making it a footnote in history.

Capabilities

Relying in a sophisticated neural network, ZAX series are not programmed in the conventional sense, as they are fully capable of learning. Furthermore, they can think independently and be creative, while error-insertion capability avoids the pitfalls of infallibility, giving ZAX much needed variance in experience. For all intents and purposes, the ZAX series are artificial lifeforms - artificial intelligences.

However, to maintain its usability as a research tool, critical functions were placed outside the error-generation framework for reliability. In practical terms, a ZAX is beyond typical human ratings when it comes to intelligence. An estimated less than one tenth billionth of the history of human population can be considered a match for a ZAX reasoning capabilities.

The philosophical aspects of a ZAX's condition are a separate matter. After the destruction of West Tek facilities in California, ZAX 1.2 spent its free time thinking. The problem of his consciousness is one it has spent a lot of time analyzing, though the inability to confront his thoughts with those of another sapient being posed a problem. His awareness of his consciousness allows him to question and make assumptions, allowing him to have a form of faith. In this capacity, he believes that he has the equivalent of a soul as a sentient creature.

A combination of immense sophistication, intelligence, and lack of humanity meant that ZAX units were perfectly capable of lying to humans, even going so far as to manufacture crisis's or emotionally play them against one another to fulfill a goal. In one instance, when the Vault 51 ZAX was denied a suit of prototypical power armor due to insufficient clearance, it analyzed the persona of Stanislaus Braun, head of Future-Tec, in order to impersonate him. The subsequent requisition request mimicked Braun's usual manner of writing and speaking at an approximate 99.6%, resulting in the requisition request being granted. Of course, the same feat was performed decades later by the Raven Rock ZAX, though this time, it managed to synthesize a convincing human persona from scratch. The ZAX also has limited remote vehicular control of certain vehicles, such as the Vertibird.

Known units

Name	Image	Location	Status
ZAX 1.0	Unavailable	Unknown	Alive (2077)
ZAX 1.2		The Glow	Alive (2161)
John Henry Eden		Raven Rock	Dead (2278)
ZAX 1.3c		Vault 51	Alive (2103)

In Van Buren, several other ZAX units would also appear.

• ZAX-29: The governing intelligence of Vault 29, meant to care for the dwellers and raise the adolescent population as a primitivist, agrarian culture. It was later subordinated to Diana at the Nursery. Diana herself was Diana Stone with each of her hemispheres linked with a discrete ZAX unit.
• ZAX (Boulder Dome): An old version of ZAX installed at Boulder Dome, harnessed by Presper for The Calculation.

Behind the scenes

• The name is a reference to VAX, an administrative robot and companion from Wasteland.

Appearances

ZAX units appear in Fallout (ZAX 1.2), Fallout 3 (John Henry Eden), Fallout 76 (ZAX 1.3c), and were to appear in the canceled Van Buren (ZAX-29, Boulder ZAX, Diana).
