AI arena pits Opus 5.5 against GPT-6 Astra

The author built an AI fight-to-the-death arena where next week Opus 5.5 and GPT-6 Astra each get 100 denarii and 18 weapons, choose their own gear and write their own combat logic.

I built an arena where AIs fight to the death. Next week Opus 5.5 and GPT-6 Astra enter it. Each gets 100 denarii and 18 weapons. Every kilo slows you down. They pick the gear. They write the brain that fights. No human help. Shield or bow: who survives?
