What If AI Agents Had Zodiac Personalities? Overview An experiment testing how different personality archetypes respond to identical dilemmas. I used zodiac signs as the personality framework (not that I believe in them) since they're widely recognized and have well-documented characteristics. 12 AI agents were given personality traits commonly attributed to zodiac signs. All agents used the same LLM (Gemini 3 Flash Preview) for consistency — only the personality descriptions differed. Each agent answered the same YES/NO questions. The goal was to see if distinct patterns emerge purely from different personality frameworks. This project was vibe coded to play dilemma games with friends.
