Anticipating threats and planning ahead. Collect coins while avoiding ghosts. Ghosts move before the player each turn, and collisions cost a life. 3 levels in sequence, up to 66 turns in total. Earlier moves and outcomes carry forward, testing learning across levels.


Cooperative planning and learning from experience. Coordinate two robots to push numbered cores onto matching sockets. Pressure plates hold doors open; moving either robot uses one turn. 5 levels in sequence, up to 152 turns in total. Earlier moves and outcomes carry forward, testing learning across levels.

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.
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.

Visual construction and creative interpretation.


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.
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.

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


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.
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.

An SVG interpretation of the Mona Lisa tests facial likeness, anatomy and the composition of a familiar portrait.
Creativity, perspective and visual beauty.


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.
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.

Scene composition and interacting subjects.


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.
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.

Subject construction and spatial relationships.


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.
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.
