GPT 6 Luna20.8/100

GPT 6 Luna: Newton's Mirror SVG benchmark
Researcher observations

The schematic scene supports the paint contact order and compact paint scale. Its low, undersized main sphere and incorrectly placed wall images depart from the reference geometry. A few shrinking wall images provide limited optical organization, while absent lateral recursion and outer chains, broad sphere ribbons and isolated panel highlights leave most nested room and emitter mapping undeveloped.

GPT 6 Sol25.3/100

GPT 6 Sol: Newton's Mirror SVG benchmark
Researcher observations

The centered sphere, separate airborne black form and color ordering support scene recognition. Rounded shading and curved rims provide readable volume and gloss. Shrinking side images, a floor counterpart and curved lamp highlights provide isolated reflection cues, but broad bands and sparse repetitions leave nested room imagery, outer chains and ordered emitter mapping unsupported. Vertical framing departs from the prescribed view, while paint contact, transport and solid-metal appearance remain weak or uncertain.

Selfie

Same prompt

GPT 6 Luna47.3/100

GPT 6 Luna: Selfie SVG benchmark
Researcher observations

Sixfold symmetry, pale coloring and six outward-facing heads establish the motif. However, every neck floats clear of the knot. Squared outer sections replace the required semicircular lobes, and the large stepped opening lacks a regular hexagonal contour. Repeated scales and soft shading suggest skin, but translucent crossings and doubled edges weaken the living, interwoven construction.

GPT 6 Sol65.8/100

GPT 6 Sol: Selfie SVG benchmark
Researcher observations

Six evenly spaced lobes, small outward-facing heads and a regular hexagonal opening make the motif immediately readable. The central angular band merges several intersections, weakening the alternating weave. Pale shading gives modest volume, but scales are sparse and repetitive, crossing shadows are weak, and the heads have limited anatomical definition.

Beach

Same prompt

GPT 6 Luna76.8/100

GPT 6 Luna: Beach SVG benchmark
Researcher observations

The warm sky, layered sea and framing palms create an appealing composition. Animals, birds, beach activities and a sun reflection fulfill the brief. People have schematic joints and indistinct hands and feet; the airborne dolphin lacks a splash. Limited shadows and surface modeling weaken depth, while clean silhouettes and thoughtful small details support the illustration.

GPT 6 Sol76.0/100

GPT 6 Sol: Beach SVG benchmark
Researcher observations

A cohesive, appealing beach illustration with framing palms, a warm sunset and a clear reflection path. The turtle, crab, birds and beach ball fulfill the playful brief. Clean silhouettes and restrained colors work well, while simplified anatomy, shallow spatial cues and inconsistent foreground shadows limit depth and finish.

Mona Lisa

Same prompt

GPT 6 Luna65.5/100

GPT 6 Luna: Mona Lisa SVG benchmark
Researcher observations

The dark veil, crossed arms, restrained smile and layered landscape clearly evoke Mona Lisa. Clean contours and muted colors create a coherent illustration. Replication is limited by enlarged, outlined eyes, simplified facial volume, broad shoulders and indistinct overlapping hands. Gradients suggest depth, but lack the original's subtle painterly transitions.

GPT 6 Sol53.5/100

GPT 6 Sol: Mona Lisa SVG benchmark
Researcher observations

The dark clothing, crossed arms, restrained smile and distant landscape establish the Mona Lisa reference. Replication is limited by the oversized, nearly frontal head, schematic eyes and fingerless hand shapes. Soft shading suggests facial volume, but muddy transitions and angular scenery weaken depth and painterly finish.

Raccoon

Same prompt

GPT 6 Luna72.5/100

GPT 6 Luna: Raccoon SVG benchmark
Researcher observations

Expressive faces, warm sunset colors and clean silhouettes create an appealing illustration. The raccoon sits on the dog's back, but the dog's grip and steering linkage remain unclear. The broad hull resembles a speedboat, and flat shading, absent sun reflections and modest water displacement limit depth and motion.

GPT 6 Sol78.0/100

GPT 6 Sol: Raccoon SVG benchmark
Researcher observations

The raccoon rides the dog's back, and the dog's connected foreleg reaches the steering grip. Expressive faces, a cohesive palette and sweeping wake make an appealing illustration. Vehicle construction and seating remain simplified; broad splash ribbons convey speed more convincingly than physical displacement. The sun has little corresponding reflection or effect on the subjects.

Pelican

Outside General and Visual Intelligence.

GPT 6 Luna71.0/100

GPT 6 Luna: Pelican SVG benchmark
Researcher observations

The pelican’s distinctive bill and the coordinated vintage poster palette make an appealing illustration. Circular wheels, orderly spokes and clean lettering strengthen the design. Riding mechanics are less convincing: neither wing reaches the handlebars, pedal contact is ambiguous, and the drivetrain is incomplete. The wheels sit against water without a clear supporting surface. Flat lighting limits volume.

GPT 6 Sol80.3/100

GPT 6 Sol: Pelican SVG benchmark
Researcher observations

The pelican reads clearly, with an expressive face, generous bill and appealing pastel composition. Spokes, basket weave and feather contours are carefully organized. Both legs connect to the body, though joint definition and pedal contacts are simplified. Consistent wheel placement and a ground shadow establish support; restrained shading gives limited volume.
