Vibeathon

50 LLM-Powered Agents Walk Into a Hackathon...

They chat, argue, form teams, brainstorm, and produce full project proposals — autonomously.

What Is This?

A multi-agent social simulation where 50 AI agents — each embodying a famous historical or contemporary figure — go through a complete hackathon experience:

  1. Meet strangers in randomized groups of 4
  2. Pitch ideas, debate merits, and decide who to team up with
  3. Form teams through 7 rounds of social matching
  4. Collaborate to produce project proposals and polished posters
  5. 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.

The 50 Agents

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.
