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.

Fledge Alpha13.9/100

Fledge Alpha: Newton's Mirror SVG benchmark
Researcher observations

The candidate communicates a round metallic sphere, three paint colors and a separate airborne black blob. Its hovering support relationship, displaced framing and unresolved paint interaction limit physical credit. Sparse planar light ghosts and a soft sphere highlight provide little evidence for the required wall/floor repetitions and curved nested mirror imagery.

Selfie

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.

Fledge Alpha72.8/100

Fledge Alpha: Selfie SVG benchmark
Researcher observations

A coherent, appealing mascot with expressive eyes, a cheerful beak and a readable swept-back silhouette. Its larger forward foot and trailing feathers suggest a running stride, but the upright body, stiff legs and minimally articulated feet limit convincing motion. Clean flat shapes suit the brief, while uneven feather junctions and incomplete cream accents reduce polish.

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.

Fledge Alpha61.5/100

Fledge Alpha: Beach SVG benchmark
Researcher observations

A cheerful, recognizable sunset beach with a cohesive warm palette and clear accessories. Simple construction, uncertain palm support, an ambiguous upper boundary and schematic reflections limit depth and finish. The scene communicates its subject successfully but lacks the developed forms, lighting and detail of exceptional illustration.

Mona Lisa

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.

Fledge Alpha44.0/100

Fledge Alpha: Mona Lisa SVG benchmark
Researcher observations

A recognizable but basic Mona Lisa reinterpretation with a coherent silhouette and subdued palette. Curtain-like hair obscures much of the face, while elongated facial construction and oversized, minimally articulated hands substantially weaken replication. Soft shading supplies modest volume, but anatomy, landscape depth and purposeful detail remain underdeveloped.

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.

Fledge Alpha74.0/100

Fledge Alpha: Raccoon SVG benchmark
Researcher observations

An appealing sunset illustration with recognizable characters and a clear riding action. Color, expression and silhouette are stronger than anatomical construction: overlapping paws obscure support, the dog's steering limb is simplified, and the vehicle controls lack definition. The wake conveys movement, while lighting and water reflections remain decorative.

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.

Fledge Alpha: Pelican SVG benchmark
Researcher observations

A clear, cheerful illustration with a recognizable pelican, coherent bicycle silhouette and tidy composition. Simplified leg articulation, steering contact, mechanical detail and lighting keep it at a competent illustrative level.
