Sundar Pichai 展示 Antigravity /swarm 功能：子智能体迭代生成 3D 鹈鹕骑车游戏
Google 把 /swarm 多智能体功能直接演示给你看了：Builder 和 Critic 子智能体自己跑 Blender 和 Three.js、自己检查渲染，最后真的做出了能玩的 3D 游戏。做智能体工作流或游戏开发的可以看看这套编排思路，和 Cursor 那种单智能体模式思路不一样。
Google CEO Sundar Pichai 在 X 上分享了一个由 Carbon 制作的演示：用 Antigravity 新推出的 /swarm 功能，让 Builder 和 Critic 两类子智能体以迭代循环方式协同工作，完成长时程编程任务。最终产出是一个可玩的 3D 游戏——一只鹈鹕在 Google Mountain View 园区骑自行车。
技术流程上，子智能体跨 Blender 和 Three.js 两个工具运行，并且会检查自己渲染的画面来校验输出效果，而非单纯生成代码。Builder 负责构建，Critic 负责审查，两者循环往复直到结果达标，这是 /swarm 多智能体协作机制的一次公开展示。
这个演示也侧面展示了 Antigravity 与 Cursor、Claude Code 等编程工具的差异路径：把多智能体编排和视觉自查直接内置进产品。对做游戏开发、3D 内容生成或智能体工作流的开发者来说，/swarm 的实际协作模式值得参考。
Carbon made a pelican demo so you don't have to 😅 fun test of long-horizon coding and the new /swarm feature in Google @Antigravity . Builder and critic subagents ran iterative loops across Blender and Three.js - checking their own renders to build a playable 3D game of a pelican biking around our Mountain View campus.
