Redditor pits Claude Fable 5.1 vs GPT 6 Astra on a robot arm painting task

Reddit user KungRaLeo replicated an X post that gave GPT 6 Astra control of a SO-101 robot arm to paint the Golden Gate Bridge, but changed the task to filling shapes with a single color and ran it with both Claude Fable 5.1 and GPT 6 Astra on the same arm.

The two models produced similar results in how well the shapes were filled, but a survey of his friends pointed to a surprising consensus. He's asking the community to weigh in on which model painted better.
