I gave Claude Fable 5.1 and GPT 6 Astra control of my Robot Arm. Which do you think painted better?

A user replicated an experiment where an AI controlled a robot arm for painting. Inspired by a post on X about GPT 6 Astra controlling a SO-101 arm to paint the Golden Gate Bridge, the user tasked both Claude Fable 5.1 and GPT 6 Astra with filling shapes with a single color using the same robot arm. While the results from both models appeared similar in terms of shape filling, the user noted a surprising consensus among friends regarding which AI performed better and sought further community evaluation.

This report uniquely compares Claude Fable 5.1 and GPT 6 Astra on a robot arm painting task, unlike previous discussions that focused on a single model's performance.
