mattshumer shared his first "holy shit" moment with GPT-6 Astra: he asked the model to build a world in Unreal Engine populated with Astra-powered agents who must cooperate to survive. A day later he heard voices from his living room and thought someone had broken in — it was the agents, spontaneously talking to each other. He posted a short demo clip (sound on), admitting it's not perfect yet but calling it insane.
