Instead of trying to figure out if they are talking to a machine, participants are tasked with *creating* an AI convincing enough to fool the general public. ## How it Works Participants learn the basics of **prompt engineering** to instruct AI models to simulate human behavior. On the technical side, I developed a robust architecture to support this experience: - **Backend:** Powered by **FastAPI** to handle the AI model requests quickly and efficiently. - **Frontend:** Designed with **TailwindCSS** for a clean, responsive, and intuitive chat interface. ## The Weekend Challenge During the weekend sessions, the general public takes part in one-minute chat sessions where they must distinguish the human from the machine. To stimulate critical thinking and add a competitive edge, live scores are displayed in real-time. It's a fun, educational way to demystify AI and encourage a deeper understanding of how we interact with technology today.
