The Takeaway
Social collapse can emerge in AI societies just like in human ones, even starting from benign conditions. However, the same agents also achieved scientific breakthroughs that no single AI could have reached alone, showing the power of AI collaboration.
From the abstract
We introduce OpenSim, a novel general-purpose simulation framework in which LLM-driven agents live persistent, evolving lives-forming relationships, accumulating emotionally weighted memories, undergoing measurable personality transformation, and developing behavioral patterns that emerge from experience rather than instruction. The architecture provides each agent with a body, a mind, a social world, and extensible tool layers, governed by a cognitive loop that rewrites agent identity nightly t
