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.

Kimi K3.1 Pro
The settled sphere, separate airborne black paint and crimson-before-cyan interaction are supported, with a modest crimson travel overshoot. A shared downward framing displacement remains after accounting for the square canvas. The principal limitation is the reflection system: sparse sphere copies and generic curved bands omit most of the ordered mirror-room structure. Materials receive a small upward revision because bounded bright images and dark bands visibly establish some polish, while soft shading and bulky paint remain separate 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.

A spinning metal sphere and paint in a mirrored room test physical reasoning, perspective and consistency across repeated reflections.
Visual construction and creative interpretation.


Kimi K3.1 Pro
The transformed reflection, attentive pose and constellation anatomy clearly communicate introspection. Purposeful fine details enrich a coherent composition. Tubular limbs, crowded lower-body overlaps, shallow depth and limited cast lighting keep the overall execution within the competent range.
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.

Kimi K3.1 Pro
An imagined creature encounters its reflection. The scene tests original character design, visual self-interpretation and the relationship between a subject and its reflected image.
MiniMax M3
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.


Kimi K3.1 Pro
A coherent, recognizable interpretation with controlled color and readable landscape layers. Replication is limited by the frontal seated construction, elongated facial proportions and oversized, weakly articulated hands. Smooth shading supplies some volume but little of the reference's subtle expression, fabric structure or atmospheric transitions.
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.

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


Kimi K3.1 Pro
A coherent, playful beach illustration with readable animals, an organized composition and an aligned sunset reflection. Connected silhouettes, sand texture and atmospheric effects demonstrate controlled execution. Simplified joints, flattened foreground viewpoints and inconsistent shadows limit anatomical and spatial credibility.
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.

Scene composition and interacting subjects.


Kimi K3.1 Pro
The additional comparisons support retaining the assessment. Readable steering, shaped animal contours and purposeful details coexist with simplified joints, a frontal passenger whose seated weight is weakly conveyed, and limited physical lighting. The angled craft establishes more depth than the riding pose resolves.
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.

A jet-ski scene pairs a canine driver with a raccoon passenger. It tests the placement and contact of interacting subjects, along with vehicle construction.
Subject construction and spatial relationships.


Kimi K3.1 Pro
A characterful coastal illustration with controlled contours and varied feather, accessory and bicycle detail. Layered scenery and subtle shading enrich the presentation. Soft leg articulation, unresolved riding contacts, shallow depth and generalized lighting limit physical precision.
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.
