What this article says

文章从 GPT-6 Astra 用 Blender 建模、生成 3D 世界这一现象切入,指出这些能力其实是它新增的 computer use 能力的副产品。作者表示自己直接阅读了相关源码,重点拆解让 Astra 表现突出的那个执行循环:模型如何观察屏幕、决定下一步操作、调用工具并在多轮之间维持状态。结论是 Astra 的强项不在于单次生成质量,而在于这个循环把视觉输入、动作执行和反馈校正串成了可稳定重复的流程,因此才能在 Blender 这类复杂 GUI 软件里连续完成多步任务。文章面向想理解 agent 与 computer use 实现细节的读者。

GPT-6 Astra broke the internet with its ability to use blender and generate 3D worlds, all a byproduct of it's new computer use capabilities.

I dove into the source code and wrote about the loop that makes Astra so good: https://x.com/i/article/2097058174125944832
