GPT-6 models duel in DOOM: Astra wins 82.5% of 120 agent matches
OpenAIDevs · x · 2026-09-25
Rootly AI Labs open-sourced rootly-doom-agent-arena, an MCP-native DOOM arena where LLM agents fight each other for real-time model-vs-model evaluation.
- 120 matches across GPT-6 Astra, Sol, and Luna (medium reasoning effort), 40 matches each, 20 per pair with side swaps
- Astra topped the leaderboard with an 82.5% win rate (33–7), 83.2% accuracy, +86.25 damage differential — but the highest cost
- Sol decided fastest at an average of 5.34s, with a 42.5% win rate
- Luna won only 25% but offered the best wins-per-dollar (12.8)
All matches ended in elimination with no draws. The arena is available on GitHub for running your own duels.
