Newton's Mirror

Same task instructions

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

The judgment

GPT-6.1 Terra Low

Deformed colored paint and a separate airborne black body establish readable interaction history. Cyan has travelled too far, framing differs substantially, and the mirror system supplies only elementary bands and oval copies. Missing recursive geometry, nested spherical imagery and emitter mapping remain the dominant weaknesses.

MiniMax M3

The centered sphere, aligned left wall image, smaller lower-left continuation and partially occluded floor image provide recognizable local mirror coherence. Cyan remains airborne, the main sphere resembles white marble, and missing right-side imagery, recursive optics and panel mappings leave the scene substantially incomplete.

Selfie

Different task instructions

Visual construction and creative interpretation.

The judgment

GPT-6.1 Terra Low

Six attached outward-facing heads, delicate scales and soft ivory shading establish an orderly decorative motif. Separate paddle-shaped bodies replace the required interlocking loops and leave no enclosed central hexagon. Surface detail provides interest, but repeated simple forms, schematic faces and limited anatomical modeling constrain the result.

MiniMax M3

The oversized coral M silhouette dominates clearly, with an expressive charcoal face and appealing miniature body. Limbs connect coherently and the cube reads clearly. The lowered left hand only loosely suggests the requested hip pose. Thin highlights and simple gradients provide limited sculptural volume; the cube's glow and grounding shadow are restrained.

A pale serpent woven into an interlocking knot tests connected anatomy, repeated structure and readable overlaps. Organic surface detail must work with the overall geometry.

A small robot with an oversized angular head presents a glowing object. The scene tests character proportions, gesture and contrasting materials.

Mona Lisa

Same task instructions

Precise visual recall and portrait reconstruction.

The judgment

GPT-6.1 Terra Low

A recognizable, coherent portrait with purposeful facial detail, warm local volume and layered scenery. The frontal pose, enlarged face, merged hands and shallow clothing construction substantially limit replication and drawing skill. The visible successes support retaining the current assessment.

MiniMax M3

The centered portrait, dark hair and muted palette suggest Mona Lisa, but characteristic likeness and pose are poorly reproduced. The broad oval face lacks her subtle smile; rounded shoulders and a lone mittenlike hand leave the crossed-arm construction unresolved. Warm shading supplies some volume, while blurred landscape bands, generic clothing and indistinct features limit the drawing.

Beach

Same task instructions

Creativity, perspective and visual beauty.

The judgment

GPT-6.1 Terra Low

A coherent sunset scene demonstrates the beach, animals, birds and reflections. Flowing silhouettes, warm color transitions and intact attachments are its strongest properties. Simplified anatomy, the turtle's elevated viewing angle and symbolic surface effects constrain drawing complexity and physical depth.

MiniMax M3

A cheerful, coherent sunset illustration with framing palms, warm gradients and an aligned sun reflection. Animals and beach toys add character, but their construction remains basic. The sailboat appears suspended above the water horizon, while absent cast shadows weaken foreground contact. Clean geometric shapes provide polish without substantial texture or depth.

Raccoon

Same task instructions

Scene composition and interacting subjects.

The judgment

GPT-6.1 Terra Low

Recognizable animals, a coherent craft and sweeping wake make an appealing cartoon. Basic limb construction, weakly demonstrated raccoon seating and limited shared perspective constrain the scene. Small identifying details work well, while lighting and materials remain broadly graphic.

MiniMax M3

The raccoon sits above the dog's back, and the dog reaches toward the jet ski controls. Expressive faces and a vivid sunset make the scene appealing. Construction is simplified: the dog's paws and steering grip are ambiguous, the hull is shallow, and blurred wake patches give limited water displacement. Sunset glow exceeds the lighting modeled on the riders.

Pelican

Same task instructions

Subject construction and spatial relationships.

The judgment

GPT-6.1 Terra Low

A coherent coastal illustration with a distinctive pelican, controlled contours and clearly organised bicycle wheels. Visible saddle support and shaped neck and wing contours earn credit beyond basic geometric construction. Rubbery legs, unresolved pedal contacts and absent steering contact limit the riding action. Lighting and materials remain restrained and spatially shallow.

MiniMax M3

The pelican's long bill, pouch and curved neck read clearly, and the warm sunset gives the composition appeal. Bicycle construction weakens the riding action: feet do not convincingly engage the pedals, crank connections are unclear, and body support is unresolved. Clean silhouettes and orderly spokes provide a competent illustrative finish.
