Jungian Archetypes in AI DesignThe application of Carl Jung's psychological archetype framework to AI persona design. Jung identified universal character patterns - the Hero, the Caregiver, the Sage, the Trickster, and others - that appear across cultures and resonate at a deep psychological level because they reflect fundamental human experiences and needs. When applied to AI, these archetypes create personas that feel immediately familiar and emotionally coherent. Commitify's Drill Sergeant maps to the Hero/Warrior, the Zen Master to the Sage, the Slay Bestie to a modern Trickster/Companion archetype. The framework provides a rigorous basis for persona differentiation beyond surface-level tone.k-NN (k-Nearest Neighbors)A simple algorithm that classifies something by looking at the k most similar examples it already knows.Knowledge baseA stored, structured collection of information an AI can draw on when answering questions or making judgments.Knowledge graphA database that stores information as a network of entities and the relationships between them.Large Behavior Model (LBM)Lirio's proprietary model class.
