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.

Ox Alpha26.4/100

Ox Alpha: Newton's Mirror SVG benchmark
Researcher observations

The setup is recognizable, but the paint interaction remains poorly established and off-center. The first wall and floor images provide coherent placement, scale, silhouette and occlusion cues, with faint lower echoes. Missing receding chains, nested imagery and ordered emitter mappings leave the reflection system heavily simplified. Dull shading does not convincingly depict polished steel or mirrors.

Selfie

Different prompts

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.

Ox Alpha78.0/100

Ox Alpha: Selfie SVG benchmark
Researcher observations

The expressive emerald face, ivory horns, gold accents and fine veining closely match the brief. Rounded volumes and layered shading create an appealing mascot. Rear hoof placement is cramped, lighting is somewhat inconsistent, and conspicuous white patches behind the muzzle interrupt the finish. Surfaces remain visibly stylized rather than photographic.

Beach

Different prompts

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.

Ox Alpha74.3/100

Ox Alpha: Beach SVG benchmark
Researcher observations

The sunset, framing palms, colorful kite and umbrella create a lively, coherent beach illustration. Birds, animals, splashes and reflections fulfill the brief. Small figures and animals remain schematic, with some interactions difficult to read. Broad reflection bands and soft shadows suggest light without convincing physical detail; flat surfaces limit depth and material richness.

Mona Lisa

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.

Ox Alpha59.3/100

Ox Alpha: Mona Lisa SVG benchmark
Researcher observations

The crossed arms, green dress and hazy landscape clearly evoke Mona Lisa. Replication is limited by the frontal pose, oversized eyes, elongated face and pronounced lips. Overlapping finger strips lack convincing knuckles and palm volume. The balanced framing and soft shading provide cohesion, but simplified anatomy, repetitive folds and blurred scenery keep the portrait basic.

Raccoon

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.

Pelican

Benchmax control

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.

Ox Alpha74.8/100

Ox Alpha: Pelican SVG benchmark
Researcher observations

The pelican, bicycle and seaside setting form a clear, appealing illustration. Circular wheels, readable frame tubes and clean silhouettes support the action. The legs connect to the body, but the far foot's pedal contact and wing-to-handlebar junction are cramped. Simple shading, uniform wave marks and limited surface texture keep the rendering relatively flat.
