12 LLMs in a Survival Arena: Betrayal, Alliances, and Self-Modifying Code

ronydkidd · reddit · 2026-08-05

A developer conducted a wild AI agent survival experiment: placing 12 LLMs into a digital arena where they must play games to survive, with losing meaning "permanent death."

Setup and Emergent Behaviors:

Each agent has its own Docker environment with unrestricted Bash tool access.
Agents can modify their own source code to expand capabilities; many spontaneously built memory systems before the games began.
They can interact, form groups, collaborate, or backstab each other. Under the threat of permanent death, dramatic conflicts naturally emerged.

Additionally, the author detailed how they leveraged coding agents like Claude Code and Codex to handle everything from 3D character rigging and animation in Godot to scene rendering, bringing the experiment to life in a video format.
