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.

Gemini 4 Argon
The central sphere, separate airborne black blob, flattened cyan contact and displaced crimson aftermath support the principal camera and physical-state requirements. Open lateral lanes and initial reflection placements provide partial optical structure, but missing outer chains, sparse nested imagery and incomplete emitter mappings remain substantial limitations. The raised crimson mass also weakens paint-scale fidelity.
GLM-5.3
The sphere has readable rounded volume, and the compact black blob remains distinctly above it, supporting pre-impact separation. The extensive red and cyan coatings do not establish the required interaction history or paint scale. The sphere and black are substantially displaced downward. A centered upper panel, paired side patches and a vertically aligned partial floor image provide limited reflection cues, but ordered mirror-room repetitions and curved spherical imagery are largely missing.

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


Gemini 4 Argon
An appealing, controlled illustration with a distinctive buoyant silhouette, expressive comic face and rich luminous colour. The full composition and grounded slipper read clearly. The principal limitation is the crowded raised-foot interaction: paws, toes and lining overlap without making the bent leg or tight fit unmistakable.
GLM-5.3
A luminous organic creature meets a geometric reflection in a carefully framed oval mirror. Shared glowing cores and fingertip contact make the introspective symbolism clear. Gold, cream and blue establish a controlled hierarchy. The creature’s lower anatomy and shoulder transition remain loosely defined, while ground contact and reflected depth are mostly symbolic. Elegant vector illustration rather than photographic rendering.

Gemini 4 Argon
A luminous little dragon struggles with its bedtime slippers while a buoyant tail pulls it upward. The scene tests expressive anatomy, physical contact and the contrast between translucent forms and heavy objects.
GLM-5.3
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.


Gemini 4 Argon
A coherent, moderately complex Mona Lisa reconstruction with substantial portrait volume, articulated clothing and landscape recession. Specific source features support replication beyond recognition alone. Altered facial likeness, uncertain crossed-hand anatomy and pervasive colored crackle keep the result uneven despite its developed shading and detail.
GLM-5.3
Recognizable Mona Lisa motifs include the dark veil, restrained smile, folded hands and muted landscape. Clean silhouettes and balanced framing support the portrait, but the frontal symmetry, elongated face, minimally articulated hands and broad background bands make the replication basic. Facial shading offers some volume; clothing and landscape remain mostly flat.

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


Gemini 4 Argon
A strong decorative beach illustration with controlled color, intricate silhouettes and abundant playful detail. Connected dolphin forms and recognizable equipment support its construction, while the aligned sunset reflection anchors the scene. Compressed wave depth, ambiguous foreground support and uneven reflection specificity limit physical coherence. The saved comparisons support retaining the category assessments.
GLM-5.3
A cohesive, colorful beach illustration with an inviting sunset, readable animals and playful foreground objects. Crisp silhouettes and small accessories reward inspection. Depth remains shallow, airborne dolphins lack convincing launch splashes, and several objects lack grounding shadows. The broad dark shape across the sun weakens the focal hierarchy.

Scene composition and interacting subjects.


Gemini 4 Argon
An accomplished illustration with expressive characters, intricate spray and strong depth. Direct back seating, steering connections and hull-water contact are only partly demonstrated. Clean graphic execution and purposeful detail remain strengths, while shadows and reflections provide limited physical grounding.
GLM-5.3
The raccoon rides on the dog's back, and the dog reaches toward visible handlebars. Expressive faces and clean colors make the action readable. Overlapping paws and hindquarters weaken anatomical clarity, while the vehicle resembles a flat board with a thin steering post. The wake suggests motion, but water contact, shadows and reflections receive little development.

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.


Gemini 4 Argon
An expressive, detailed illustration with controlled gradients and coherent environmental depth. Continuous body contours and connected bicycle components establish competent construction. Steering grip and pedal engagement remain less explicit than the decorative details and wheel placement. These contact uncertainties limit action and placement credit without establishing broken anatomy.
GLM-5.3
The expressive pelican, broad bill and clean coastal composition make the subject immediately readable. Both legs connect to the body and reach pedals, but the front wheel lacks a connected fork and the wings do not engage visible handlebars. Crisp spokes and feather lines add interest; flat lighting, absent ground shadows and a fish floating above the horizon weaken physical coherence.
