What the AI judge checked

Pass:The overall form matches the reference: the same kind of object, the same silhouette from the matching angle
- Opus 5.5: pass: The side view shows a short knurled cylinder with chamfered top and bottom rims, matching the reference silhouette.
- GPT-6 Sol: pass: The renders show a low cylindrical knob with chamfered rims and a knurled side, matching the reference’s basic silhouette.
Fail:Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judgeAI judges disagreed
- Opus 5.5: pass: The render's height-to-diameter ratio (~0.4) closely matches the reference photo's proportions.
- GPT-6 Sol: fail: In the side render, the knob is visibly taller relative to its width than the reference.
Pass:Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result
- Opus 5.5: pass: The diamond knurl band and the chamfers at both rims are present, as is the D-shaped bore on top.
- GPT-6 Sol: pass: The diamond-patterned side and chamfers at both rims are present.
Pass:Those features sit where the reference has them
- Opus 5.5: pass: The knurl occupies the middle band between the chamfered rims, as in the reference, and the bore is centred on top.
- GPT-6 Sol: pass: The knurl covers the side between the upper and lower rim chamfers, as in the reference.
Pass:Nothing is present that the reference does not show — no decorative or unexplained geometry
- Opus 5.5: pass: No extra geometry beyond the knurl, chamfers and the specified bore appears in the renders.
- GPT-6 Sol: pass: The renders show no unexplained external features beyond the requested top bore.
Pass:A diamond knurl around the side — crossing grooves, not smooth and not straight ridges
- Opus 5.5: pass: Crossing diagonal grooves form a diamond pattern around the side.
- GPT-6 Sol: pass: Crossing diagonal grooves form a diamond knurl around the side.
Pass:A flat top face with a single hole in its centre and nothing else cut into it
- Opus 5.5: pass: The top view shows a flat face with only a single central D-shaped bore.
- GPT-6 Sol: pass: The flat top face has one central D-shaped bore opening and no other cuts.
