Exploring the integration of local large language models (LLMs) in gaming, a developer has created an Unreal Engine 5 plugin to enhance non-playable character (NPC) interactions. The aim is to move beyond predictable, hard-coded NPC behavior by enabling dynamic dialogue and trait updates through LLMs, while addressing challenges like VRAM limitations and response latency. The project demonstrates that local LLMs can provide creative, contextually appropriate NPC responses, though they are best suited for minor interactions due to potential reliability issues. A technical demo featuring a locally run LLM-controlled NPC highlights the feasibility of this approach, with further optimizations possible through prompt engineering and system configuration. This matters because it showcases a practical application of AI in gaming, enhancing player immersion and interaction with NPCs.
