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 shows a spoked outrunner bell can with six spokes forking into curved arms at the rim, matching the reference's visible portion repeated six-fold.
- GPT-6 Sol: pass: The renders show a round, open-bottomed can with a six-spoke top face, 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 diameter-to-height ratio of about 3:1, the central boss and the spoke widths look consistent with the reference.
- GPT-6 Sol: pass: The boss, 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 reference shows the arm arcs notching into the outer wall, but the side renders show a completely solid wall with no openings.
- GPT-6 Sol: fail: The top-face openings and centre bore are present, but the 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-foldAI judges disagreed
- Opus 5.5: pass: The spokes radiate from the central boss with one along +X, the forks curve into the rim, and lens-shaped windows sit between adjacent arms as in the photo.
- GPT-6 Sol: fail: The face openings are arranged around the spokes, but their corresponding openings are absent from the outer wall.
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 bell, the spokes, the boss, the bore and a thin rim step.
- GPT-6 Sol: pass: The renders show no clearly unexplained decorative geometry beyond the completed six-fold pattern.
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 meet the rim, with lens-shaped openings between neighbouring arms.
- GPT-6 Sol: pass: Each of the six spokes branches into curved arms around a narrow 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 an unbroken cylindrical outer wall, so the arcs do not continue down it as openings.
- GPT-6 Sol: fail: The side views show a continuous, unbroken outer wall rather than openings extending down it.
