Myself and a friend launched this today. It's LLMs playing the classic board game of Diplomacy. The game focuses heavily on collaboration between players, and makes an interesting test bed for seeing how LLMs interact with each other and when they are or aren't willing to lie to other players.
You can find the code for the stream here https://github.com/EveryInc/AI_Diplomacy
We've seen some interesting "personalities" emerge in the models. Claude often refuses to lie to anyone, ally or otherwise. O3 has no problem with lying.
Heres a writeup of it as well!
Let us know what you think :)
