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.

Simplified prompt

A shiny steel ball spins in a room with mirrored walls and a mirrored floor. Red, cyan and black paint float above it. Gravity suddenly switches on. Draw the scene a moment later, as the ball drops and paint begins landing on its spinning surface. Show the reflections repeating through the room.

The exact prompt is held back to prevent benchmaxxing.

Ling 3.1 Flash39.6/100

Ling 3.1 Flash: Newton's Mirror SVG benchmark
Researcher observations

Central placement, separate airborne black paint and the elongated crimson coating earn substantial state and placement credit. Cyan contact remains unresolved. A few isolated sphere images provide limited optical evidence, while the defining repeated mirror structure is missing. Readable opaque metallic volume and restrained paint scale justify increased material credit. Core: 61.5/170; including the floor reward: 61.5/180.

Selfie

Different prompts

DeepSeek V4 Pro 081342.4/100

DeepSeek V4 Pro 0813: Selfie SVG benchmark
Researcher observations

The whale’s warm eye, lavender assistant and tilted shell convey appealing character. However, the shrimp and reciprocal inspection are unresolved, the large bubble and upper tail are cropped, and the flipper’s grip is unclear. Broad competing color fields and conspicuous stepped edges weaken the flowing composition. Gradients suggest volume, but lighting and translucent materials remain uneven.

Simplified prompt

Draw a curious blue whale examining a tiny shrimp through a bubble magnifying glass. The shrimp looks back through its own smaller bubble lens. An octopus assistant sits on the whale's head while rising bubbles lift a little seaweed wig above it.

Ling 3.1 Flash77.0/100

Ling 3.1 Flash: Selfie SVG benchmark
Researcher observations

An appealing, coherent storybook ant with a clear expression, complete silhouette and readable signal mechanism. Clean curves and warm accents support the composition, while simplified joints, schematic hardware, limited material differentiation and modest light interaction constrain its finish.

Mona Lisa

Same prompt

DeepSeek V4 Pro 081316.9/100

DeepSeek V4 Pro 0813: Mona Lisa SVG benchmark
Researcher observations

Dark hair, a restrained smile and a hazy landscape make the reference recognizable. Severe construction problems dominate: oversized looping sleeves surround a background-colored opening, and the crossed hands lack coherent wrist and forearm connections. Rigid symmetry and elongated facial proportions weaken expression. Soft skin gradients and clean contours provide limited finish.

Ling 3.1 Flash24.0/100

Ling 3.1 Flash: Mona Lisa SVG benchmark
Researcher observations

A basic, uneven Mona Lisa interpretation with a clear facial focal point, articulated eyes and modest tonal volume. Weak likeness, oversized head proportions, unclear shoulders, curled bare arms and indistinct hands limit replication. The compressed composition and rectangular torso weaken an otherwise coherent earthy palette.

Beach

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.

Exact prompt

Ling 3.1 Flash65.7/100

Ling 3.1 Flash: Beach SVG benchmark
Researcher observations

A coherent sunset illustration with harmonious color, clean silhouettes and readable beach details. Its calm composition works well, while playful activity is modest. Simplified animal anatomy, shallow shoreline layering, repetitive foliage and a geometric reflection limit drawing sophistication and naturalism.

Raccoon

Same prompt

DeepSeek V4 Pro 081354.0/100

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.

Ling 3.1 Flash63.1/100

Ling 3.1 Flash: Raccoon SVG benchmark
Researcher observations

An appealing sunset cartoon with recognizable animals, expressive faces and coherent landscape layers. The sky and warm water streaks provide its strongest rendering. Ambiguous seated support, stiff forelegs, a shallow hull and an unclear steering connection limit construction. Clean shapes and readable accessories add finish, while restrained spray and flat surfaces limit material and motion effects.

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for DeepSeek V4 Pro 0813 and Ling 3.1 Flash.

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.

Ling 3.1 Flash70.0/100

Ling 3.1 Flash: Pelican SVG benchmark
Researcher observations

A clean, appealing pelican illustration with a readable bicycle and coherent landscape. Bill shading, feather layers and faint wheel shadows provide modest depth. Uncertain pedal contact, simplified leg construction and limited material rendering keep the result within competent illustration quality.
