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 result is a round cylindrical knob with a chamfered top, matching the reference silhouette in the iso and side views.
- GPT-6 Sol: pass: The produced part has the same cylindrical silhouette and sloped top rim as the reference.
Pass:Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge
- Opus 5.5: pass: Width-to-height ratio and chamfer size look the same as the reference in the side views.
- GPT-6 Sol: pass: The body height, diameter, and chamfer width appear to match the reference.
Pass:Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result
- Opus 5.5: pass: Both the top chamfer and the bottom hex socket from the reference are present.
- GPT-6 Sol: pass: The top chamfer and underside hexagonal socket visible in the reference are both present.
Pass:Those features sit where the reference has them
- Opus 5.5: pass: The hex socket is centered on the underside with the same orientation as the reference, and the chamfer is on the top edge.
- GPT-6 Sol: pass: The chamfer circles the top edge, and the hexagonal socket is centered on the underside 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 appears beyond the body, chamfer, and hex socket.
- GPT-6 Sol: pass: The renders show no additional bosses, holes, or decorative geometry.
Pass:The top edge is chamfered, not sharp
- Opus 5.5: pass: Side views show a beveled ring at the top edge, and the top view shows a chamfer band around the face.
- GPT-6 Sol: pass: A distinct sloped band separates the flat top from the cylindrical side.
Pass:A hexagonal socket is visible in the bottom view
- Opus 5.5: pass: The bottom view clearly shows a centered hexagonal recess.
- GPT-6 Sol: pass: The bottom view clearly shows a recessed hexagonal socket.
