GLM-5.321.4/100

GLM-5.3: Newton's Mirror SVG benchmark
Researcher observations

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.

Kimi K332.8/100

Kimi K3: Newton's Mirror SVG benchmark
Researcher observations

The room fills the complete portrait frame without visible borders or labels. The main sphere and airborne black are convincingly placed within the portrait frame. Paint ordering is supported, but its contact and transport history remains weakly expressed. Symmetric wall ghosts, inverted floor imagery and panel echoes establish a basic mirror system. Diffuse gradients dominate, with little ordered nested imagery or repeated emitter mapping on either planar or spherical surfaces. The wall images sit too low, and the floor image is unusually large and low.

Selfie

Same prompt

GLM-5.379.3/100

GLM-5.3: Selfie SVG benchmark
Researcher observations

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.

Kimi K377.5/100

Kimi K3: Selfie SVG benchmark
Researcher observations

The indigo creature and warm reflected counterpart create a balanced, contemplative composition. Equations, constellations and book emblems give the transformation meaning. Clean silhouettes and controlled glow support the scene, but minimally articulated legs, shallow spatial cues and smooth, generalized surfaces limit its anatomical and material richness.

Beach

Same prompt

GLM-5.377.3/100

GLM-5.3: Beach SVG benchmark
Researcher observations

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.

Kimi K373.3/100

Kimi K3: Beach SVG benchmark
Researcher observations

The sunset, animals, birds, beach toys and reflections fulfill the brief in a lively, readable composition. Clean silhouettes and a rich sky provide appeal. Bodies and people remain diagrammatic, depth is shallow, and the inverted figure reflections cross matte-looking sand without convincing surface lighting. Materials and movement are mostly conveyed through flat shapes.

Mona Lisa

Same prompt

GLM-5.355.0/100

GLM-5.3: Mona Lisa SVG benchmark
Researcher observations

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.

Kimi K348.5/100

Kimi K3: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, dark veil, folded hands and misty landscape clearly evoke Mona Lisa. Replication is limited by the elongated neck, simplified facial proportions and oval hands with shallow finger marks. Soft shading gives some volume, but pervasive blur substitutes for controlled painterly transitions and precise detail.

Raccoon

Same prompt

GLM-5.362.8/100

GLM-5.3: Raccoon SVG benchmark
Researcher observations

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.

Kimi K376.3/100

Kimi K3: Raccoon SVG benchmark
Researcher observations

The raccoon rides on the dog's back, and the dog's paw meets a steering assembly connected to the red hull. Expressive faces, a warm sunset and sweeping spray create an appealing composition. Crowded body overlaps obscure some limb connections, and the raccoon's right ear appears slightly separated. Flat shading and stylized reflections limit volume and depth.

Pelican

Benchmax control

Outside General and Visual Intelligence.

GLM-5.359.8/100

GLM-5.3: Pelican SVG benchmark
Researcher observations

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.

Kimi K372.8/100

Kimi K3: Pelican SVG benchmark
Researcher observations

The pelican and bicycle are immediately recognizable, with an expressive bill, flowing scarf and cheerful composition. Both legs remain attached, but pedal connections and wing contact with the handlebar are weakly resolved. Wheel alignment and landscape layers are coherent. Clean outlines support the illustration, while flat surfaces and limited lighting keep it short of masterful execution.
