AI 造了个无限世界，还能多人联机玩
你见过能无限玩下去、还能多人一起进的 AI 游戏世界吗？这篇论文造了一个——LingBot-World 2.0。它不只是画面好看，关键是：你可以在里面做各种事，攻击、射箭、施法、射击，而且 AI 会实时响应，60 帧每秒，不卡顿。更厉害的是，它引入了两个 AI 角色：一个「飞行员」负责控制角色行动，一个「导演」负责根据剧情生成新场景。这意味着世界不是固定的，而是随着你的行为不断演化。它还支持多人同时在线，一起探索。虽然这还不是一个能下载的游戏，但它展示了 AI 世界模型从「看视频」到「真正可交互」的跨越。
📄 原文摘要(英文)
We present LingBot-World 2.0 (also known as LingBot-World-Infinity), an advanced iteration of LingBot-World featuring four distinct upgrades. (1) Our model achieves an unbounded interaction horizon while maintaining consistent output quality, benefiting from a carefully crafted causal pretraining paradigm. (2) Through distilling a real-time variant from the base model, our system guarantees rapid response time, sufficient to drive 720p video streams at 60 fps. (3) Compared to the previous version, this update introduces highly diverse interactive elements, comprising a broader spectrum of actions (e.g., attacking, archery, spell-casting, and shooting) alongside a richer variety of text-driven events. (4) We pioneer the integration of an agentic harness within the domain of world modeling, wherein a pilot agent is tasked with planning and executing character behaviors, while a director agent is responsible for synthesizing novel environmental elements as the scene progresses. Additionally, to facilitate a shared experience, we develop an interface that permits multiple players to simultaneously immerse themselves in this vivid world simulator. We pair our primary 14B model with a lightweight 1.3B counterpart, which supports effortless deployment on a single GPU.
