What the AI judge checked

Fail:The overall form matches the reference: the same kind of object, the same silhouette from the matching angle, allowing for the requested change: the photograph shows only part of the bell; compare the visible part and expect the rest to repeat it six-foldAI judges disagreed
- Opus 5.5: pass: The render shows an open-bottomed cylindrical can with a six-spoke face, a central boss, and a bore, matching the visible portion of the photographed bell.
- GPT-6 Sol: fail: The six-fold spoked face resembles the reference, but the rendered can has a continuous outer wall instead of the reference’s side openings.
Pass:Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge, allowing for the requested change: the photograph shows only part of the bell; compare the visible part and expect the rest to repeat it six-fold
- Opus 5.5: pass: The diameter-to-height ratio, the boss size and the spoke widths look broadly consistent with the reference and the stated dimensions.
- GPT-6 Sol: pass: The rendered boss, rim, and overall can height appear proportionate to the reference and supplied dimensions.
Fail:Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result, allowing for the requested change: the photograph shows only part of the bell; compare the visible part and expect the rest to repeat it six-fold
- Opus 5.5: fail: The reference shows the rim cutouts continuing down the side wall as notches, but the side views show a completely plain, unbroken wall.
- GPT-6 Sol: fail: The face openings and central bore are present, but the openings continuing down the outer wall are missing.
Pass:Those features sit where the reference has them, allowing for the requested change: the photograph shows only part of the bell; compare the visible part and expect the rest to repeat it six-fold
- Opus 5.5: pass: The six spokes radiate from the central boss, one lies along a horizontal axis, and the forks meet the rim at the spoke ends as in the photo.
- GPT-6 Sol: pass: The six spokes, forked ends, and rim openings repeat in the expected positions around the central boss.
Pass:Nothing is present that the reference does not show — no decorative or unexplained geometry, allowing for the requested change: the photograph shows only part of the bell; compare the visible part and expect the rest to repeat it six-fold
- Opus 5.5: pass: No decorative or unexplained geometry is visible beyond the spokes, the forks, the boss, the bore and the can wall.
- GPT-6 Sol: pass: The renders show no decorative or unexplained features beyond the bell’s boss, spokes, openings, and rim.
Pass:Each spoke splits into two thin arms that curve into the rim, the way the photo shows — not straight spokes and not round holes
- Opus 5.5: pass: The top view shows each spoke splitting into two curved arms that join the rim, enclosing a lens-shaped opening.
- GPT-6 Sol: pass: Each of the six radial spokes branches into curved arms around an elongated opening near the rim.
Fail:The arms' arcs continue down the outer wall as openings in the side of the can
- Opus 5.5: fail: The side views show a solid cylindrical wall with no openings, so the arcs do not continue down the wall.
- GPT-6 Sol: fail: Every side view shows a solid, uninterrupted cylindrical wall with no openings continuing down it.
