GPT-6 Astra drives a $200 robot arm to paint the Golden Gate Bridge
OpenAI's robotics intern used Astra in a loop of taking a photo, writing a code plan, executing, and checking every second or two, letting a 3D-printed SO-100 arm paint five pictures.
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
