GPT-6 Astra 操控 200 美元机械臂画金门大桥
OpenAI 机器人实习生用 Astra 拍照—写代码计划—执行—每秒校验的闭环，让 3D 打印 SO-100 机械臂画了五幅画。
OpenAI's robotics intern gave GPT-6 Astra a $200 robot arm, and 4.7M people watched it paint the Golden Gate Bridge The TBPN stream where he explains how it works has 11,024 views on YouTube. He gets to it at minute 45 The loop: Camera -> one photo at 512p -> a plan written in code -> execute -> a check every second or two -> small fixes Astra takes one photo, writes "a plan in code" (45:56), and "plans sort of a minute of action out" (47:09). Between checks the code runs the brush The arm is a Hugging Face SO-100. Open source, fully 3D printable, "around $200 or so" (50:06). Classic robotics gear runs into the thousands Each painting took one to two hours He plans to frame all five attempts. The first came out upside down. By the fifth, the Golden Gate Bridge is readable
