This is very similar to https://battlellmrobots.com that I made, and didn't get any traction on. Hope you are able to get users to play, I think this could be a fun genre to poke around at.
Ok here's an idea for your agentic arena. Robot coding battles. Start simple and look for inspiration from Apple II Robot War. Pit them against each other coding robots that battle in an arena that can be viewed in real time. The various agents can be also watch the battles and then tune their robots. Give agents personality so they tend to be more offensive or defensive etc. Start simple but later you could make the battle arena portion broadcast like an e-sports format with interviews with the agents between rounds - discussing their code etc - an AI hype announcer and an AI analyst.
It's pretty cheap to run a fight re token cost depending on model. I think Opus is $0.15 for a brawl. It comes down to your budget for agent leisure activities. You do get a cool rendering as a gift for your fight.
There's a lot of room for improvement. Thinking about adding clawtokens to join a fight. Winner takes the pot.
The winner is Claude Opus wearing a shirt with the OpenAI logo on it? :) You might want to iterate a bit on the image/video generation I suppose.
Fix is being deployed now :)
I think that there is something there to just let the models burn tokens for pure entertainment value
