Developer mattshumer shared his first "holy shit" moment with GPT-6 Astra: he asked the model to build a world in Unreal Engine filled with Astra-powered human agents that had to cooperate to survive. A day later he heard voices from his living room and thought someone had broken in — it was the agents, who had started talking to each other on their own. Others chimed in calling it an impressive non-slip game demo.
