Psyche Ai

Psyche Ai is an open-source subjectivity kernel designed for AI agents, enabling them to develop persistent, emergent personalities and behavioral traits in response to interaction history—not just scripted or prompt-based personas. It models local subjective state, relational dynamics, and adaptive control loops, fundamentally altering how agents behave based on ongoing context, relationship dynamics, and prior interactions. Psyche is aimed at developers and researchers building advanced AI agents or systems seeking nuanced and persistent agent behaviors without additional API/model calls.
