DeepSeek V4 Pro 0813: Newton's Mirror SVG benchmark
Researcher observations

The central sphere and gross paint state are coherent. Reduced circular side images and paired overhead quadrilaterals offer limited, spatially organized reflection cues, but the floor-sphere image, receding mirror-room structure, outer chains, nested imagery and curved emitter mappings are largely missing or invalid.

Muse Spark 1.316.9/100

Muse Spark 1.3: Newton's Mirror SVG benchmark
Researcher observations

The paint state is incorrectly and poorly drawn, despite a recognizable sphere-and-paint setup. The oversized sphere, oversized compact paint bodies, and blurred wall and floor images further limit the result. Isolated reflection cues provide very little support for the required repeated virtual rooms, nested spherical imagery or emitter mapping.

Selfie

Different prompts

DeepSeek V4 Pro 081370.5/100

DeepSeek V4 Pro 0813: Selfie SVG benchmark
Researcher observations

The reaching pose, glossy eyes and lavender moon create an appealing storybook scene. Both rabbits read clearly, and the main limbs connect coherently. However, the towering ears pass through the helmet boundary, plush fur is largely absent, and broad gradients simplify the suit and terrain. Rectangular clipping around several blurred rock halos weakens the finish.

Muse Spark 1.375.3/100

Muse Spark 1.3: Selfie SVG benchmark
Researcher observations

The luminous creature and geometric mirror counterpart communicate self-recognition through a coherent palette and expressive eyes. The transformed reflection is purposeful. Simple oval anatomy, ambiguous reaching-arm construction, shallow spatial staging and limited illumination of nearby surfaces keep the illustration below exceptional execution.

Beach

Same prompt

DeepSeek V4 Pro 081362.0/100

DeepSeek V4 Pro 0813: Beach SVG benchmark
Researcher observations

The glowing sunset, framing palms and layered shoreline create a coherent beach scene with animals, birds and playful accessories. The airborne blue animal has unclear anatomy, while flat foliage, weak ground contact and broad oval reflections limit depth and finish. The image is appealing but visibly simplified.

Muse Spark 1.365.5/100

Muse Spark 1.3: Beach SVG benchmark
Researcher observations

The warm sunset, framing palms and colorful beach accessories create an appealing scene with the requested animals, birds and reflections. Construction remains schematic: the raised hand misses the kite string, and a doglike silhouette hangs above the water without clear support. The sun reflection establishes a focal path, but shadows and materials lack depth. An unexplained horizontal bar crosses the sun.

Mona Lisa

Different prompts

DeepSeek V4 Pro 081342.5/100

DeepSeek V4 Pro 0813: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, dark clothing and hazy landscape evoke the Mona Lisa, but replication is limited by an elongated frontal face, oversized looping sleeves and unresolved crossed hands. The background-colored opening through the lower body weakens construction. Soft facial shading adds some volume, while sparse finger marks and broad flat shapes leave the drawing basic and uneven.

Muse Spark 1.341.0/100

Muse Spark 1.3: Mona Lisa SVG benchmark
Researcher observations

Dark hair, a restrained smile and overlapping hands suggest Mona Lisa, but replication is weak. The face is markedly elongated, the hands are oval pads with faint finger strokes, and the atmospheric landscape is absent. Soft gradients provide basic volume, while the frontal symmetry, shallow space and sparse clothing detail limit the portrait’s drawing quality.

Raccoon

Same prompt

DeepSeek V4 Pro 081358.5/100

DeepSeek V4 Pro 0813: Raccoon SVG benchmark
Researcher observations

The masked raccoon riding the steering dog is readily recognizable, with expressive faces and energetic diagonal movement. The oversized tail dominates the composition, limb connections are difficult to trace, and the jet ski has little structural depth. Blurred spray and a heavy oval shadow weaken water contact, while the glowing sun produces little corresponding illumination.

Muse Spark 1.368.8/100

Muse Spark 1.3: Raccoon SVG benchmark
Researcher observations

The raccoon clearly rides on the dog's back, and the dog's paws reach the jet ski controls. Expressive faces and bright colors make the scene appealing. Simplified joints, crowded steering geometry and shallow hull perspective limit construction. The sun has no corresponding water reflection, and the splash shapes convey speed more clearly than convincing displacement.

Pelican

DeepSeek V4 Pro 081372.8/100

DeepSeek V4 Pro 0813: Pelican SVG benchmark
Researcher observations

A clearly recognizable pelican cycles through a balanced, expressive illustration. The sweeping bill, shaded plumage and carefully drawn wheels give it character. Mechanical construction is weaker: the chain loop sits below the crank, and foot-to-pedal and wing-to-handlebar contact are ambiguous. Smooth gradients provide volume, but the scene remains visibly stylized.

Muse Spark 1.372.0/100

Muse Spark 1.3: Pelican SVG benchmark
Researcher observations

The pelican and bicycle are immediately recognizable, with an expressive face, bold bill and cheerful composition. Both legs connect to the body and reach pedal-like supports, but articulation, saddle support and wing contact with the handlebar remain unclear. Wheel alignment and layering are coherent. Simple landscape shapes, generic shadows and limited material variation constrain the finish.
