Newton's Mirror

Same task instructions

Physics, perspective and recursive reflections, tested together. Explore the test ↗

The judgment

DeepSeek-V4-Pro-0813

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.

Gemini 4 Argon

The central sphere, separate airborne black blob, flattened cyan contact and displaced crimson aftermath support the principal camera and physical-state requirements. Open lateral lanes and initial reflection placements provide partial optical structure, but missing outer chains, sparse nested imagery and incomplete emitter mappings remain substantial limitations. The raised crimson mass also weakens paint-scale fidelity.

Selfie

Different task instructions

Visual construction and creative interpretation.

The judgment

DeepSeek-V4-Pro-0813

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.

Gemini 4 Argon

An appealing, controlled illustration with a distinctive buoyant silhouette, expressive comic face and rich luminous colour. The full composition and grounded slipper read clearly. The principal limitation is the crowded raised-foot interaction: paws, toes and lining overlap without making the bent leg or tight fit unmistakable.

Gemini 4 Argon

A luminous little dragon struggles with its bedtime slippers while a buoyant tail pulls it upward. The scene tests expressive anatomy, physical contact and the contrast between translucent forms and heavy objects.

Mona Lisa

Different task instructions

Precise visual recall and portrait reconstruction.

The judgment

DeepSeek-V4-Pro-0813

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.

Gemini 4 Argon

A coherent, moderately complex Mona Lisa reconstruction with substantial portrait volume, articulated clothing and landscape recession. Specific source features support replication beyond recognition alone. Altered facial likeness, uncertain crossed-hand anatomy and pervasive colored crackle keep the result uneven despite its developed shading and detail.

Beach

Same task instructions

Creativity, perspective and visual beauty.

The judgment

DeepSeek-V4-Pro-0813

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.

Gemini 4 Argon

A strong decorative beach illustration with controlled color, intricate silhouettes and abundant playful detail. Connected dolphin forms and recognizable equipment support its construction, while the aligned sunset reflection anchors the scene. Compressed wave depth, ambiguous foreground support and uneven reflection specificity limit physical coherence. The saved comparisons support retaining the category assessments.

Raccoon

Same task instructions

Scene composition and interacting subjects.

The judgment

DeepSeek-V4-Pro-0813

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.

Gemini 4 Argon

An accomplished illustration with expressive characters, intricate spray and strong depth. Direct back seating, steering connections and hull-water contact are only partly demonstrated. Clean graphic execution and purposeful detail remain strengths, while shadows and reflections provide limited physical grounding.

Pelican

Same task instructions

Subject construction and spatial relationships.

The judgment

DeepSeek-V4-Pro-0813

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.

Gemini 4 Argon

An expressive, detailed illustration with controlled gradients and coherent environmental depth. Continuous body contours and connected bicycle components establish competent construction. Steering grip and pedal engagement remain less explicit than the decorative details and wheel placement. These contact uncertainties limit action and placement credit without establishing broken anatomy.
