Uble-do and the Cy
Psyche is the proper term for a category of high-performance AGI typically responsible for managing the affairs of a city or equivalently-sized ship. Astute readers may be familiar with a science fiction equivalent called a Mind; other terms for these machines include Spirits, Sparks, Djinni, Machine Souls, and various other capitalised references to paranormal psychology. Psyches are distinguished from other classes of large-scale AIs in that they are encoded in a substrate that allows self-organising hyperdimensional neural geometry, obtaining a fourth dimension by exploiting quantum effects peculiar to the medium. Small examples of this architecture can be found in the form of Delegate Psyches, which are used to control systems aboard small craft such as transit shuttles, but as the seeding and construction of a new Psyche is an immense undertaking, non-Delegate specimens are almost universally huge structures, usually occupying the inner layer of a Matrioshka brain built around a small artificial star or comparable power source.
The Lyrisclensiae build Psyches using a unique crystal material that acts as a medium for self-propagating cellular automata. These automata are slow, but grow geometrically, allowing a vast architecture to be unfolded procedurally using a chain reaction. Newer designs have surpassed typical four- and even five-dimensional formats, and allow for direct addressing between sub-critical components.
Culturally, the Lyrisclensiae pride themselves on the immaculate reason of these machines; they are seen as supreme arbiters of fact, logic, justice, and morality. Accordingly they are afforded immense respect outside of the Lyrisclensian College, and in Thet's darkest days provided a level of scientific and cultural continuity that could not be matched by any other effort. This has not been without backlash; during the late years of the Reed Administration and the rise of the Gryphon Republic their motives were questioned, and many Psyches in Thet were relocated elsewhere during Ivilon Desqrit's rise to power. Tellingly, however, it would not have been possible to wage Desqrit's war against the Hogedepi without the assistance of the Psyches that remained behind, as the Lyrisclensian armada was almost entirely responsible for halting the expansion of the Hogedep.
Hatel Psyches are a parallel development to the Lyrisclensian invention, and are so named more by analogy than as a result of scientific cooperation between the sibling species of Lyranids. Like Lyran Psyches, they use optical circuits to perform non-classical operations on complex datasets, grow and adapt over time, use immense amounts of power, and exploit materials science to pack extra dimensions into a three-dimensional substrate. This substrate is a unique ceramic rather than a crystal, called bara chan huo (碧船火, or blue ship fire), which can withstand greater temperatures than the crystals used by the Lyrans, and hence operate at higher frequencies. Consequently, the Hatel design actually outperforms typical Lyrisclensian designs for most algorithms in QMA, so fewer processing units are required.
The cultural significance of the Hatel implementation is somewhat less monochromatic than the Lyrisclensian Psyche. Hatelese ships, like the Hatel themselves, are known for their diverse and eccentric personalities, which are protected by (and subject to) law much like their human counterparts. Famous Psyches have, among other things, started and ended civil wars, traded crewmembers for archaeological curios, and written Doctor Who fan-fiction.

Pesenese AI and the Epyesteyi
Telaian ship AI is somewhat different from typical artificial general intelligence.
