AI造了个无限世界，还能多人联机玩
你玩过的开放世界游戏，场景和互动都是程序员写死的。这篇论文让AI自己生成无限世界：你打字说“射箭”，AI就生成角色拉弓放箭；你说“下雨”，天空立刻变暗。更关键的是，它把世界拆成两个AI——一个控制角色行动，一个实时生成新场景，所以你能一直探索，不会撞到边界。还支持多人同时进入同一个AI世界，就像联机游戏。目前模型有140亿参数和13亿参数两个版本，小模型一张显卡就能跑。虽然离真正的《头号玩家》还远，但这是第一次让AI世界真正“活”起来，且能多人共享。

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.
