GPT 5.6 Sol28.3/100

GPT 5.6 Sol: Newton's Mirror SVG benchmark
Researcher observations

The central sphere and paint ordering are supported, but a frontal, centrally converging chamber replaces the required corner perspective. The first wall and floor images have incorrect placement and scale relationships. Sparse reflection cues remain, while continuous outer chains, open lateral sightlines, dense planar light sequences and curved nested spherical imagery are largely missing.

Grok 4.732.8/100

Grok 4.7: Newton's Mirror SVG benchmark
Researcher observations

Some sphere reflections are correctly placed, with useful size progression and a floor image. Their overlapping side continuations and inverted floor paint order provide additional local optical cues. The gross paint sequence is recognizable, although crimson is a little too low. Incorrect lamp projections and absent nested and receding imagery still leave the mirror system largely incomplete.

Selfie

Different prompts

GPT 5.6 Sol64.5/100

GPT 5.6 Sol: Selfie SVG benchmark
Researcher observations

Six evenly spaced lobes, outward-facing heads and a clear central hexagon establish the requested knot. The ivory silhouette is controlled, but broad crossing bands resemble rigid strips, shading provides limited muscular volume, and repetitive scale lines extend across black loop openings. Small oval heads have readable eyes and mouths but limited anatomical character or moist surface detail.

Grok 4.768.8/100

Grok 4.7: Selfie SVG benchmark
Researcher observations

The bold spiral dominates an appealing, restrained silhouette, with crisp angular turns and subtle charcoal highlights. However, a visible background gap separates the shell from the body, making the shell appear suspended. The connected head and delicate eye stalks read clearly, while shading and small features remain simple.

Beach

Same prompt

GPT 5.6 Sol75.8/100

GPT 5.6 Sol: Beach SVG benchmark
Researcher observations

The purple-to-gold sunset, framing palms and varied beach activities create an appealing, coherent illustration. The sun’s reflection establishes a clear focal path. Figures and animals are recognizable but geometrically simplified; airborne dolphins lack convincing splashes, and the boat reflection is schematic. Clean silhouettes and playful details succeed more strongly than anatomical depth or material realism.

Grok 4.762.3/100

Grok 4.7: Beach SVG benchmark
Researcher observations

The warm sunset, blue water and scattered beach activities create a cheerful, readable composition. Animals and equipment use basic silhouettes, with limited anatomical detail and grounding. The sun reflection forms a rigid tapered strip, and foreground objects lack cast shadows. Clean shapes support the illustration, but depth, materials and drawing complexity remain modest.

Mona Lisa

Same prompt

GPT 5.6 Sol64.0/100

GPT 5.6 Sol: Mona Lisa SVG benchmark
Researcher observations

The crossed hands, dark dress and winding landscape establish the Mona Lisa composition. Replication is limited by enlarged eyes, an elongated face and a more frontal pose. Broad gradients suggest volume, but outlined features and flattened, overlapping fingers weaken the portrait. The frame and restrained palette unify the image; visible grain adds texture without convincing painterly transitions.

Grok 4.749.5/100

Grok 4.7: Mona Lisa SVG benchmark
Researcher observations

The dark clothing, crossed hands, restrained smile and muted landscape make the reference recognizable. Replication is limited by the oversized, simplified face, elongated neck and rounded hands with poorly resolved fingers. Gentle facial shading adds volume, but the clothing and landscape remain flat. Angular veil overlaps and a hard horizontal background boundary weaken the finish.

Raccoon

Same prompt

GPT 5.6 Sol76.3/100

GPT 5.6 Sol: Raccoon SVG benchmark
Researcher observations

Expressive faces, bold silhouettes and layered waves make an appealing cartoon. The raccoon sits convincingly behind the dog's shoulders, and the dog's forward paw reaches the steering grip. Steering construction and seated support remain somewhat ambiguous. The glowing sunset lacks a corresponding warm reflection or consistent illumination on the riders.

Grok 4.762.0/100

Grok 4.7: Raccoon SVG benchmark
Researcher observations

The raccoon rides clearly on the dog's back, and expressive faces, bright colors and a readable orange hull create a playful composition. Steering is unresolved: the dog's visible paws rest on the deck rather than grasping the controls. Simple body shapes and ribbonlike wake limit construction and movement. The glowing sun produces little corresponding illumination or reflection.

Pelican

Outside General and Visual Intelligence.

GPT 5.6 Sol69.3/100

GPT 5.6 Sol: Pelican SVG benchmark
Researcher observations

The expressive pelican and balanced coastal composition remain appealing, but a sky-colored slit between the neck contours above the wing leaves the central anatomy incoherent. This visible construction and layering defect prevents a clean-integrity assessment. Clustered feet lack clear pedal contacts and the chain routing is schematic; lighting and water reflections remain graphic.

Grok 4.763.3/100

Grok 4.7: Pelican SVG benchmark
Researcher observations

The pelican reads clearly through its long bill, throat pouch and curved neck. Clean pastel shapes and balanced scenery make an appealing illustration. The riding mechanism is less convincing: feet lack clear pedal contact, steering is unresolved, and the frame lacks a coherent drivetrain. Simple shading and sparse feather detail limit depth and finish.
