Fable 5.1 and GPT-6 Astra driving the same SO-101 robot arm, and the community picked the one with worse coverage

A builder replicated a circulating X demo that had GPT-6 Astra paint the Golden Gate Bridge with an SO-101 arm, but swapped the task to filling shapes with a single color so the comparison had a measurable target. After 100+ comments the subreddit's auto-summary recorded the verdict: Bot B won on technique, cleaner edges and rounder shapes despite having less coverage and missing a box entirely, while Bot A got credit for coverage and staying in the lines but was dismissed as 'pixel-dabbing'. The model identities were withheld in-thread, which is the part that makes it useful rather than a brand fight.
