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.

Qwen 3.8 Flash22.5/100

Qwen 3.8 Flash: Newton's Mirror SVG benchmark
Researcher observations

The full-frame illustration supports a central steel sphere, an airborne black blob and the relative ordering of cyan and crimson. Its faint floor return and symmetric repetitions provide sparse mirror structure; outer chains, large reflected images, nested imagery and emitter mapping remain deficient. Vertical framing is substantially displaced, and paint contact histories remain unresolved.

Selfie

Different prompts

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.

Qwen 3.8 Flash72.8/100

Qwen 3.8 Flash: Selfie SVG benchmark
Researcher observations

The towering ears, expressive eyes, astronaut suit and diagonal moon ring create an appealing storybook scene. The reaching arm connects coherently to the carrot interaction. Smooth surfaces provide little plush fur, crater depth is simplified, and bright granular fringes roughen the rings and floating rocks. One small rabbit paw appears detached beneath its body.

Beach

Same prompt

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.

Qwen 3.8 Flash73.8/100

Qwen 3.8 Flash: Beach SVG benchmark
Researcher observations

The sunset gradient, sweeping palms and aligned sun reflection create an appealing beach composition. Birds, animals, boating and beach activities satisfy the brief. Small figures and animal anatomy remain rudimentary, water movement is schematic, and contact shadows are weak. Crowded foreground details and a clipped orange disk at the top limit the finish.

Mona Lisa

Different prompts

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.

Qwen 3.8 Flash54.0/100

Qwen 3.8 Flash: Mona Lisa SVG benchmark
Researcher observations

The dark dress, crossed hands and hazy landscape evoke the Mona Lisa, but replication is limited by a generic frontal face, coarse smile and poorly articulated fingers. The gold frame has clearer definition than the portrait. Heavy mottling obscures features, while soft shading provides some volume without convincing anatomical detail.

Raccoon

Same prompt

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.

Qwen 3.8 Flash62.0/100

Qwen 3.8 Flash: Raccoon SVG benchmark
Researcher observations

The raccoon clearly rides the dog's back, with expressive features and appealing blue-orange color contrast. The dog's paws do not clearly operate connected controls, and the shallow vehicle lacks convincing jet ski construction. Clean outlines support the cartoon style, but generic shading and blurred water streaks limit depth and motion.

Pelican

Outside General and Visual Intelligence.

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.

Qwen 3.8 Flash73.5/100

Qwen 3.8 Flash: Pelican SVG benchmark
Researcher observations

The pelican's expressive face, oversized bill and flowing scarf create an appealing focal point. The bicycle has recognizable frame, chain and wheel construction, but the far foot lacks a clear pedal connection and the wing's steering contact is ambiguous. Clean contours and gentle gradients support the illustration; simplified volume and weak directional shadows limit depth.
