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 a cylindrical can with an open-spoked top face and a central hub, matching the outrunner bell in the photo.
- GPT-6 Sol: pass: The render shows a six-fold spoked face atop a cylindrical, open-bottomed bell, 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 wide, shallow can, the hub at about 40% of the diameter, and the small centre bore look consistent with the photo and the stated dimensions.
- GPT-6 Sol: pass: The central boss, rim diameter, and bell height appear close to the reference’s relative proportions.
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 photo shows the rim notched where the arcs meet the outer wall, but the side views show a completely solid outer wall with no openings.
- GPT-6 Sol: fail: The render has the central bore and curved spoke openings, but lacks the openings that continue down the side 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: Six spokes radiate from the central boss, with forks reaching the rim at matching angular positions and one spoke along a horizontal axis in the top view.
- GPT-6 Sol: fail: The curved openings are confined to the top face instead of extending onto the outer wall as in the reference.
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 appears beyond the hub, the spokes and arcs, and the can wall.
- GPT-6 Sol: pass: The render shows no clearly decorative or unexplained 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: In the top view each spoke splits into two thin curved arms that sweep into the rim, forming lens-shaped openings between neighbouring forks.
- GPT-6 Sol: pass: Each of the six radial spokes branches into two curved arms near the rim.
Fail:The arms' arcs continue down the outer wall as openings in the side of the can
- Opus 5.5: fail: All side-view renders show an uninterrupted solid cylindrical wall with no openings continuing the arcs.
- GPT-6 Sol: fail: The outer wall is uninterrupted in the side views, with no arc-shaped openings.
