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-fold
- Opus 5.5: fail: The render shows a three-spoke wheel with large windows, whereas the reference shows six spokes that each fork into two curved arms, so the face pattern does not match.
- GPT-6 Sol: fail: The render shows a three-spoke face rather than the six-fold pattern requested from the reference.
Fail: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-foldAI judges disagreed
- Opus 5.5: fail: The spoke count and widths differ: three wide spokes with large openings instead of six narrower spokes, and a solid side wall with no windows.
- GPT-6 Sol: pass: The can’s height, diameter, and central boss appear proportionate to the stated 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 forked Y-shaped arms and the wall openings seen in the reference are missing.
- GPT-6 Sol: fail: The six forked spokes and openings continuing down the outer wall are missing.
Fail: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: fail: Only three spokes are placed around the face, at 120° spacing rather than the six-fold 60° spacing of the reference.
- GPT-6 Sol: fail: The face openings follow a three-fold layout instead of the reference’s six-fold spoke placement.
Fail: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-foldAI judges disagreed
- Opus 5.5: fail: Small circular-ended cutouts at each spoke tip are present, and these do not appear in the reference.
- GPT-6 Sol: pass: The renders show no clearly decorative or unexplained features beyond the bell, boss, bore, and face openings.
Fail: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: fail: The spokes run straight to the rim with round notches at their tips and do not split into two curved arms.
- GPT-6 Sol: fail: Each rendered spoke is a broad stem, not two thin arms curving into 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-view renders show a completely solid cylindrical wall with no openings.
- GPT-6 Sol: fail: The rendered outer wall is continuous, with no openings extending down from the face.
