I built out battlellmrobots.com[1], it's a platform for battling bots written by LLMs. The documentation explains how the engine works, what information is available to the bots as they fight, and gives a couple example of example bots. Currently only have 3 users, including myself. Hopefully some more people submit bots and then it'll be more fun fighting a range of bots.
