From the AI build battle videos
The AI build battle, on your own server
Type /aibuild and an AI model builds it in front of you, block by block. Same build tools, rules and limits as the videos.
Three steps to your first build.
Put Playkeeper on your VPS
Paste this into your VPS over SSH. It checks the machine and asks before it changes anything.
curl -fsSL https://playkeeper.io/install | sudo shDon't have a VPS yet? Which one to rent

Good to know
- Your own OpenRouter key
- It's never shown in chat, the console or the logs.
- A spend cap per build and per day
- You see it before every build.
- One block at a time
- Blocks go down one by one, so everyone on the server can watch.
- For operators by default
- Other players can't start a build unless you let them.
What does a build cost?
It depends on the model and what you ask for. In the battle of 29 September, a whole build of “Build your worst nightmare” cost $0.15 with GPT-6.1 Sol, $0.30 with Claude Sonnet 5.5 and $0.75 with Claude Opus 5.5. You pay OpenRouter, with your own key.
Which models can build?
Any model on OpenRouter that can call tools, like Claude, GPT and Gemini.
Where do I get an OpenRouter key?
At openrouter.ai/keys, once your OpenRouter account has some credit. Playkeeper keeps the key on your server and never shows it again.
