They chat, argue, form teams, brainstorm, and produce full project proposals — autonomously.
Live Simulation | Voting Arena | Devpost | Full Project Overview
A multi-agent social simulation where 50 AI agents — each embodying a famous historical or contemporary figure — go through a complete hackathon experience:
- Meet strangers in randomized groups of 4
- Pitch ideas, debate merits, and decide who to team up with
- Form teams through 7 rounds of social matching
- Collaborate to produce project proposals and polished posters
- Get judged by 5 AI judges with hidden biases through live Q&A
The entire simulation runs end-to-end with zero human intervention. Agents maintain consistent personalities, form genuine preferences, and produce surprisingly creative outputs.
Each agent has a 17-dimension personality model (selfishness, risk appetite, stubbornness, empathy, communication style, etc.) and a deep character prompt (~250 lines each).
| Category | Agents |
|---|---|
| Tech Founders | Elon Musk, Steve Jobs, Mark Zuckerberg, Jeff Bezos, Sam Altman, Peter Thiel, Travis Kalanick, Elizabeth Holmes, Adam Neumann, Alexandr Wang |
| World Leaders | Barack Obama, Vladimir Putin, Xi Jinping, Donald Trump, Angela Merkel, Narendra Modi, Winston Churchill, Margaret Thatcher, Volodymyr Zelenskyy, Joe Biden |
| Artists | Kanye West, Banksy, Salvador Dali, Andy Warhol, Lady Gaga, Ai Weiwei, Damien Hirst, Marina Abramovic, Yoko Ono, Takashi Murakami |
| Historical Figures | Napoleon Bonaparte, Mahatma Gandhi, Cleopatra, Genghis Khan, Martin Luther King Jr., Nikola Tesla, Julius Caesar, Qin Shi Huang, Marie Curie, Leonardo da Vinci |
| Influencers | MrBeast, PewDiePie, Pokimane, Logan Paul, Jake Paul, Andrew Tate, Belle Delphine, Kim Kardashian, Nikocado Avocado, Addison Rae |
Yes, Vladimir Putin is the PM for a visually-impaired accessibility app. Andrew Tate and MLK are on the same team. Donald Trump does UX/UI design.
