## Safe public summary

The integration of Large Language Models (LLMs) into real-time, multi-participant virtual environments represents a paradigm shift in procedural storytelling and non-player character (NPC) behavior1. However, deploying unconstrained generative agents in a live multiplayer setting introduces critical vulnerabilities regarding latency, context overflow, and unbounded financial liability2. The foundational engineering challenge involves orchestrating a hybrid architecture that seamlessly blends deterministic game logic with stochastic AI generation, ensuring that infrastructure costs scale sub-linearly with user engagement while preserving seamless continuity4. Based on comprehensive queueing simulations, inference-cost modeling, and contemporary vulnerability analyses, th…
