How We Built Dynamic NPC Dialogue with LLMs — Lessons from Early Access
Vantage Digital Labs has developed an LLM-powered engine for dynamic NPC dialogue in video games, moving beyond static, pre-written lines. Their architecture involves a context builder, LLM API, response parser, and memory system, with a focus on prompt engineering over model size for cost-effectiveness. Key lessons learned include prioritizing response parsing and low latency, with smaller models like DeepSeek and Qwen proving viable for indie games. AI
IMPACT Enables more interactive and responsive non-player characters in games, potentially enhancing player immersion.
