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.

Grok 4.7

Some sphere reflections are correctly placed, with useful size progression and a floor image. Their overlapping side continuations and inverted floor paint order provide additional local optical cues. The gross paint sequence is recognizable, although crimson is a little too low. Incorrect lamp projections and absent nested and receding imagery still leave the mirror system largely incomplete.

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.

Grok 4.7

The bold spiral dominates an appealing, restrained silhouette, with crisp angular turns and subtle charcoal highlights. However, a visible background gap separates the shell from the body, making the shell appear suspended. The connected head and delicate eye stalks read clearly, while shading and small features remain simple.

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.

Grok 4.7

A dark snail with a geometric spiral shell tests silhouette, curved construction and restrained material shading.

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.

Grok 4.7

Dark clothing, overlapping hands and a restrained smile make the reference recognizable. The broad frontal face, elongated neck and oversized head weaken likeness and anatomical proportion; rounded hands lack convincing fingers. Gentle facial shading suggests volume, while clothing and landscape remain flat. Angular veil overlaps and a hard horizontal background boundary weaken the 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.

Grok 4.7

The warm sunset, blue water and scattered beach activities create a cheerful, readable composition. Animals and equipment use basic silhouettes, with limited anatomical detail and grounding. The sun reflection forms a rigid tapered strip, and foreground objects lack cast shadows. Clean shapes support the illustration, but depth, materials and drawing complexity remain modest.

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.

Grok 4.7

The raccoon rides clearly on the dog's back, and expressive faces, bright colors and a readable orange hull create a playful composition. Steering is unresolved: the dog's visible paws rest on the deck rather than grasping the controls. Simple body shapes and ribbonlike wake limit construction and movement. The glowing sun produces little corresponding illumination or reflection.

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.

Grok 4.7

The pelican reads clearly through its long bill, throat pouch and curved neck. Clean pastel shapes and balanced scenery make an appealing illustration. The riding mechanism is less convincing: feet lack clear pedal contact, steering is unresolved, and the frame lacks a coherent drivetrain. Simple shading and sparse feather detail limit depth and finish.
