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 render is an open-bottomed cylindrical can with a six-spoked top face and central boss, matching the bell in the photo repeated six-fold.
- GPT-6 Sol: pass: The renders show a round, open-bottomed bell with a six-spoke face and outer rim, 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 side view shows a wall height of roughly a third of the diameter, and the boss is about 40% of the outer diameter, consistent with the photo and the stated dimensions.
- GPT-6 Sol: pass: The boss, spokes, rim, and can height appear proportionate to the reference.
Pass: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: pass: The central boss with bore, six spokes, forked thin arms, outer rim ring and wall openings are all present.
- GPT-6 Sol: pass: The renders show the central bore, boss, six forked spokes, face openings, and openings in the outer wall.
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-foldAI judges disagreed
- Opus 5.5: pass: The forks sit near the rim at each spoke and the wall openings are centred on the spoke directions, one spoke along +X, as in the photo.
- GPT-6 Sol: fail: The wall openings are isolated slots rather than continuations of the curved openings at the rim.
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: pass: No decorative or unexplained geometry beyond the spoked face, rim and wall openings is visible.
- GPT-6 Sol: fail: The renders add six distinct capsule-shaped wall slots not shown in the reference.
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 near the rim into two thin curved arms that sweep into the rim ring.
- GPT-6 Sol: pass: Each of the six spokes splits into two thin arms that curve toward the rim.
Fail:The arms' arcs continue down the outer wall as openings in the side of the can
- Opus 5.5: fail: The wall openings are separate stadium-shaped slots below a solid top band, not a continuation of the arms' arcs over the edge and down the wall as in the photo.
- GPT-6 Sol: fail: The curved face openings stop at the rim, while separate rounded slots pierce the wall below.
