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.

Glyph Cluster
Rounded sphere volume, compact colored forms and crimson-below-cyan ordering provide limited agreement. The visible paint does not establish the required interaction history, the sphere and black blob are displaced from the prescribed projection, and most of the defining mirror-room structure is missing or unresolved. The faint reflection echoes earn limited optical credit.
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.

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


Glyph Cluster
A charming palette and three expressive companions make the concept recognizable. The dominant paper enclosure overwhelms the small group, the plum character lacks a clear brace silhouette, and the cuddle remains difficult to trace. Sparse furnishings, ambiguous folds and generalized shading limit the promised lived-in richness and tactile depth.
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.

Glyph Cluster
Punctuation-shaped companions gather inside a curled paper home. The scene tests expressive silhouettes, close interaction and the coherence of a detailed miniature environment.
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.
Precise visual recall and portrait reconstruction.


Glyph Cluster
The portrait has a continuous body silhouette, attached sleeves and hands, and simple landscape depth. Its oversized pale head enclosure nearly erases the expression, while separated fists, ochre clothing and frontal construction weaken Mona Lisa likeness. Sparse detail, flat materials and ambiguous facial layers leave the drawing seriously unresolved.
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.

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


Glyph Cluster
A cheerful, recognizable beach illustration with playful accessories and mostly clean silhouettes. Sunset colors and soft glow supply atmosphere, but abbreviated anatomy, unexplained airborne animals, weak ground contact and absent water reflections limit physical coherence. Small details add interest without consistently resolving construction or materials.
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.

A plank, computer mouse and blueberry in a steel room test physical stability, spatial relationships, materials and lighting.
Scene composition and interacting subjects.


Glyph Cluster
Recognizable animals and clean shapes give the scene charm, but the requested steering action is visibly incomplete. Simplified joints, weak vehicle construction and uncertain water contact limit physical coherence. Flat lighting, sparse functional detail and a small focal group keep the illustration basic despite its tidy edges.
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.

Subject construction and spatial relationships.


Glyph Cluster
A readable cartoon with open framing, aligned bicycle wheels and modest atmospheric effects. Pelican likeness is approximate, while the narrow neck, crowded feet, absent steering contact and unclear drivetrain weaken the riding action. Clean shapes help presentation, but shallow space and inconsistent shading limit the finish.
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.
