Inside a Game Where AI Agents Never Sleep

What happens to an MMORPG when half the players never log off? Issac Lee, who runs AI and blockchain experiments at NEXUS, has been testing that idea. His team is filling game worlds with agent players instead of scripted NPCs, so a new title feels alive from day one. We get into why agent-generated content could be the next step after studio-made and user-generated games. We also cover how agent populations might solve the chicken-and-egg problem every multiplayer launch faces, and what it means when your fellow players are relentless and never need sleep. Isaac walks through the NEXUS lab: a text-to-3D world builder for Roblox, an AI pipeline that turns ONE store novels into short web dramas, a loop-based tool for natural pixel animation, and Da Vinci, the internal multi-agent framework the team uses to ship. Then the conversation turns to infrastructure. We talk about why NEXUS went from 200 hand-defined agent roles to a much thinner harness, whether custom harnesses still matter now that Claude and Codex exist, and why the Kimi release pushed the company to start building its own small data center for inference. We close on context: how much of your life you should hand to an AI, what personalized meeting notes could look like, and why shopping agents may force every ecommerce site to rethink who it's designing for.
