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 render shows a short knurled cylindrical knob with a central D-bore in the top, matching the reference silhouette from the three-quarter view.
- GPT-6 Sol: pass: The renders show the same low, round knob silhouette with a flat top and textured side.
Pass:Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge
- Opus 5.5: pass: The side views show a height of roughly 0.45 of the diameter, and the bore is about a quarter of the diameter, consistent with the reference.
- GPT-6 Sol: pass: The knob’s height, width, and central bore appear similar in relative size to 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 knurl, the chamfers at the top and bottom rims, and the D-shaped central bore are all present.
- GPT-6 Sol: pass: The central D-shaped bore, diamond knurl, and chamfered outer rims are visible.
Pass:Those features sit where the reference has them
- Opus 5.5: pass: The bore is centred on the top face and the knurl covers the side band between the chamfers, as in the reference.
- GPT-6 Sol: pass: The bore is centred on the top face, while the knurl wraps around the side 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 is visible; the bottom face is plain and the top shows only the bore.
- GPT-6 Sol: pass: The renders show no additional holes, bosses, or decorative features.
Pass:A diamond knurl around the side — crossing grooves, not smooth and not straight ridges
- Opus 5.5: pass: The side views show crossing diagonal grooves forming a diamond pattern.
- GPT-6 Sol: pass: Crossing diagonal grooves form clear diamonds 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 a single central D-shaped hole and nothing else cut into it.
- GPT-6 Sol: pass: The flat top face has one central bore and no other cuts.
