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-foldAI judges disagreed
- Opus 5.5: fail: The result is a plain can with six straight spokes and trapezoidal windows, whereas the reference shows forked spokes with arched openings, so the silhouette of the spoke pattern differs.
- GPT-6 Sol: pass: The renders show an open-bottomed cylindrical bell with a six-spoke top face, matching the reference’s overall type and silhouette.
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 roughly 91:29 and the central boss and bore sizes look plausible relative to the reference.
- GPT-6 Sol: pass: The rendered can’s height, rim width, and central region appear broadly consistent with the 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 forked arms and the arched cutouts running into the side wall seen in the photo are missing; the side wall renders as a solid cylinder.
- GPT-6 Sol: fail: The renders lack the forked spoke ends and openings that continue down 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-fold
- Opus 5.5: fail: The windows are placed between straight spokes rather than reproducing the Y-fork arrangement of the reference.
- GPT-6 Sol: fail: The reference’s openings extend from the spoke ends into the rim and wall, while the rendered openings stop within the top face.
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 beyond a can, spokes, a boss and a bore is visible.
- GPT-6 Sol: pass: The renders show no apparent decorative or unexplained features beyond the requested bell, boss, and centre bore.
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 top view shows six straight spokes of uniform width that do not split into two arms.
- GPT-6 Sol: fail: Each rendered spoke remains a single broad connection to the rim rather than splitting into two thin curved arms.
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 a completely solid outer wall with no openings.
- GPT-6 Sol: fail: The rendered outer wall is continuous and has no openings extending down from the spoke pattern.

Measured

✓ watertight: ok
