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.

Qwen3.6 27b: Newton's Mirror SVG benchmark
Researcher observations

The artwork depicts a shaded sphere, distinct paint colors and a separate airborne black blob. Crimson's apex overlap does not establish its earlier interaction and transport, while cyan's recent contact remains unsupported. Horizontal centering supplies limited camera agreement, but the sphere, black blob and prominent panel have substantial placement or projection departures. A few planar echoes provide reflection evidence; isolated patches and gradients replace most of the required mirror structure.

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.

Qwen3.6 27b56.3/100

Qwen3.6 27b: Selfie SVG benchmark
Researcher observations

An appealing decorative illustration with coordinated ornament, flowing panels and three glowing orbital lights. The arm arrangement reverses the requested sides. Uncertain neck continuity, concealed leg articulation, simplified paws, crowded chest jewelry and shallow surface modeling limit pose clarity and finish.

Simplified prompt

Draw a friendly capybara floating in ornate green and white robes. A glowing halo and small floating orbs surround it, giving it the feel of a gentle fantasy guide.

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.

Qwen3.6 27b: Mona Lisa SVG benchmark
Researcher observations

The portrait loosely evokes Mona Lisa through its palette and silhouette. Readable pupils, brows and lips provide limited detail, and the torso remains continuous. The frontal elongated face, unresolved chest-level limb forms, shallow landscape and pervasive blur substantially weaken likeness, anatomy and finish.

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.

Qwen3.6 27b56.7/100

Qwen3.6 27b: Beach SVG benchmark
Researcher observations

A recognizable sunset beach with balanced palms, clean shapes and effective warm–cool contrast. Small animals and play equipment address the brief, but rudimentary anatomy, uncertain water contacts, sparse reflections and flat materials keep the drawing basic or uneven.

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.

Qwen3.6 27b57.7/100

Qwen3.6 27b: Raccoon SVG benchmark
Researcher observations

A readable cartoon with balanced colors, clean shapes and a clearly supported raccoon. Continuous body construction and modest shading deserve credit. Rudimentary limbs, unresolved steering connections, stiff gestures and schematic water effects limit physical credibility and finish.

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for DeepSeek V4 Pro 0813 and Qwen3.6 27b.

DeepSeek V4 Pro 081367.5/100

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.

Qwen3.6 27b58.5/100

Qwen3.6 27b: Pelican SVG benchmark
Researcher observations

A lively, coherent illustration with recognizable pelican features, purposeful accessories and useful surface variation. Ambiguous neck layering, uncertain pedal engagement and an unresolved drivetrain limit construction. Aligned wheels and layered scenery establish placement, while inconsistent shadow direction and crowded overlaps constrain finish.
