Newton's Mirror

Same task instructions

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

The judgment

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.

MiniMax M3.1 Flash

The sphere placement, separate airborne black blob, recent cyan contact and elongated crimson aftermath support the required gross physical state. The reflection system remains severely incomplete: isolated side images, broad metallic bands and sparse light patches replace extensive mirror repetitions and curved nested imagery.

Selfie

Same task instructions

Visual construction and creative interpretation.

The judgment

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.

MiniMax M3.1 Flash

The sculptural M, confident grin and miniature theatrical pose closely fulfill the brief. Controlled gradients and clean shapes give the character volume and appeal. Moderate drawing complexity, an apparently separated shoe and ambiguous grounding limit the finish.

Mona Lisa

Different task instructions

Precise visual recall and portrait reconstruction.

The judgment

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.

MiniMax M3.1 Flash

A coherent decorative portrait combines layered hair, garment contours, linked trim and atmospheric scenery. These provide meaningful drawing complexity, but likeness remains limited by the frontal elongated face and altered clothing. Compressed hands, abrupt facial shading and cluttered local edges leave the portrait uneven.

Beach

Different task instructions

Creativity, perspective and visual beauty.

The judgment

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.

MiniMax M3.1 Flash

A controlled, detailed beach illustration with expressive animals, coherent depth and accomplished foliage and accessory drawing. Its warm palette and varied contours sustain visual interest. Simplified anatomy and object volumes limit physical conviction, while reflection streaks crossing dry-looking sand and generic shadows weaken the lighting.

Raccoon

Different task instructions

Scene composition and interacting subjects.

The judgment

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.

MiniMax M3.1 Flash

An expressive, coherent cartoon clearly demonstrates the requested riding and steering relationship. Layered animal shapes, readable vehicle depth and purposeful facial details support its drawing quality. Ambiguous grips, sparse cast shadows and simplified material responses limit physical precision.

Pelican

Different task instructions

Subject construction and spatial relationships.

The judgment

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.

MiniMax M3.1 Flash

A controlled coastal illustration with a clear pelican silhouette, detailed wheels and accomplished feather and bill drawing. Continuous body construction and grounded wheels support the scene. Ambiguous leg, pedal and steering contacts weaken the riding mechanics; approximate directional lighting and simplified materials limit physical conviction.
