Newton's Mirror

Same task instructions

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

The judgment

Cat Jam Free

The image conveys a supported central sphere, separate black paint and crimson below cyan. Its contact and transport story is partially resolved. The exterior cutaway camera and largely missing mirror system dominate the limitations; isolated discs and smooth highlights provide little coherent optical structure.

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.

Selfie

Different task instructions

Visual construction and creative interpretation.

The judgment

Cat Jam Free

A coherent, restrained cat illustration captures the pale palette and intent eyes. Its central expressive requirement—the committed forward-and-down neck bob—is insufficiently articulated. Simple geometry, faint paw construction and minimal surface detail limit the physical presence and finish.

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.

Benchmark task

Cat Jam Free

An ivory cat nods intently to music beside a tiny speaker. The scene tests feline anatomy, movement conveyed through a still pose and the contrast between pale fur and woven fabric.

DeepSeek-V4-Pro-0813

A whale and a tiny shrimp examine one another through bubble lenses, with an octopus nearby. The scene tests interacting characters, differences in scale and transparent materials.

Mona Lisa

Different task instructions

Precise visual recall and portrait reconstruction.

The judgment

Cat Jam Free

The portrait is recognizable and cleanly assembled, but replication remains basic. Its frontal symmetry, elongated silhouette, simplified facial likeness and unresolved hands differ markedly from the original. Modest skin gradients provide volume, while clothing and landscape rely on broad, flat shapes.

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.

Beach

Same task instructions

Creativity, perspective and visual beauty.

The judgment

Cat Jam Free

The scene clearly supplies the requested beach subjects and playful activity. Clean silhouettes and warm gradients support readability, but elementary drawing, ambiguous parasol construction, weak grounding and a rigid sun reflection limit its depth and finish.

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.

Raccoon

Same task instructions

Scene composition and interacting subjects.

The judgment

Cat Jam Free

An appealing cartoon demonstrates the back-riding arrangement through expressive faces and clean shapes. Uncertain steering contact, indistinct deck support and weak hull-water interaction limit physical coherence. Smooth gradients add volume, but simple rounded construction and sparse material detail constrain complexity and finish.

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.

Pelican

Same task instructions

Subject construction and spatial relationships.

The judgment

Cat Jam Free

A coherent cartoon with readable bicycle placement, controlled outlines and modest surface shading. The separated-looking upper bill weakens pelican likeness; schematic limbs, uncertain gripping contact and simplified mechanics constrain construction. Opaque wheel interiors flatten spatial relationships. Limited feather complexity and directional lighting keep the finish modest.

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.
