Shachi: A Modular, Controllable Framework for LLM-Based Agent-Based Modeling of Emergent Collective Behavior

arXiv:2509.21862v3 Announce Type: replace Abstract: How collective behaviors emerge from the interactions of individual LLM-driven agents is a central question in artificial life, yet controlled study of these emergent dynamics has been hindered by the lack of a principled simulation framework for systematic experimentation. To address this, we introduce Shachi, a principled methodology and modular framework that decomposes an agent's cognition into core components: Configuration for intrinsic identity, Memory for contextual continuity, and Tools for extended capabilities, all orchestrated by
The rapid advancement and accessibility of large language models are creating an urgent need for controlled environments to study their collective emergent behaviors, which Shachi directly addresses.
This framework provides a principled method for understanding and simulating complex AI agent interactions, which is crucial for developing and safely deploying advanced autonomous systems.
The ability to systematically experiment with and decompose LLM-driven agents into core cognitive components will accelerate research into multi-agent systems and emergent AI behaviors.
