What the AI judge checked

Pass: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: pass: The renders show an open-bottomed cylindrical can with a spoked top face, central boss and bore, which matches the motor bell in the photo.
- GPT-6 Sol: pass: The renders show a cylindrical bell with a six-fold spoked top, matching the reference’s overall form.
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 40 mm boss, thin arms and short can height relative to the diameter look broadly consistent with the reference.
- GPT-6 Sol: pass: The boss, spokes, rim, and can height appear proportionate to the visible reference.
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 side views show the arcs only as faint lines on a solid outer wall, not as the wall cut-throughs visible at the rim in the photo.
- GPT-6 Sol: fail: The top openings and centre bore are present, but the side-wall arcs appear filled rather than open.
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: Six spokes sit at 60° spacing with one along the horizontal axis, and each fork's arcs meet the rim between spokes.
- GPT-6 Sol: pass: The boss is central, and the six spokes and curved rim features repeat in the expected positions.
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: The top view shows small step notches on the outer rim at the arc ends, and the bottom view shows a wide inner annular ring with spiky arc tips that the reference does not show.
- GPT-6 Sol: pass: The renders show no obvious decorative or unexplained features.
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: Each straight spoke ends in two thin curved arms forming a semicircle that runs out to the rim, rather than a straight spoke or a round hole.
- GPT-6 Sol: pass: Each radial spoke divides into two thin, curved arms before reaching the rim.
Fail:The arms' arcs continue down the outer wall as openings in the side of the can
- Opus 5.5: fail: In the side views the arcs appear only as thin scribed lines on a closed wall, with no visible openings through the side of the can.
- GPT-6 Sol: fail: The wall shows scalloped outlines, but the areas inside them appear solid rather than cut-through openings.
