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.

Qwen3.8 27B33.3/100

Qwen3.8 27B: Newton's Mirror SVG benchmark
Researcher observations

The room fills the complete 16:9 frame without visible borders or labels. Central placement fits the wider frame, and the paint colors follow the expected vertical order. Bilateral side images, diminishing echoes and an overlapping floor image provide limited mirror depth. Broad sphere surfaces lack ordered nested room imagery, while planar panel sequences and outer chains remain missing or unresolved. Soft highlights do not establish emitter mapping, while paint attachment and transport history are only partly supported.

Selfie

Different prompts

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.

Qwen3.8 27B78.8/100

Qwen3.8 27B: Selfie SVG benchmark
Researcher observations

A cohesive emerald-and-gold illustration with a gentle expression, flowing robes, luminous halo and three clearly ringed orbs. Limbs remain connected, and the asymmetric legs communicate floating. The rounded face reads somewhat bear-like; the raised palm faces outward rather than upward, and chest-hand fingers are crowded. Clean ornamentation exceeds the comparatively simple anatomical modeling and shading.

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.

Qwen3.8 27B78.3/100

Qwen3.8 27B: Beach SVG benchmark
Researcher observations

The sweeping palm, glowing sunset and layered shoreline create an appealing composition with abundant beach activity. Birds, animals and sun reflections satisfy the brief. Animal anatomy remains schematic, wave spacing is repetitive, and shadows and reflective surfaces offer limited physical depth. Clean silhouettes and small beach details support a strong stylized illustration.

Mona Lisa

Different prompts

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.

Qwen3.8 27B42.5/100

Qwen3.8 27B: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, dark clothing and overlapping hands evoke the Mona Lisa, but replication is weak. The face is excessively elongated, the eyes stare broadly, and the hands reduce to rounded masses with shallow finger marks. Soft shading creates some volume, while the landscape remains indistinct. The precise gold frame is more resolved than the portrait.

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.

Qwen3.8 27B70.5/100

Qwen3.8 27B: Raccoon SVG benchmark
Researcher observations

The raccoon clearly rides on the dog's back, and the dog reaches the jet ski's steering grip. Cheerful expressions, a bright palette and sweeping wake make the action readable. Anatomy and machinery remain simplified, with overlapping paws and limited seat definition. Flat lighting, sparse surface detail and broad white splash shapes limit depth and finish. A clipped gray fragment interrupts the upper-left corner.

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.

Qwen3.8 27B71.3/100

Qwen3.8 27B: Pelican SVG benchmark
Researcher observations

The pelican’s oversized bill, straw hat and flowing scarf create a distinctive focal character against a well-composed coastal sunset. Wheels and frame are readable, but the wings do not reach the steering, overlapping legs obscure separate pedal contacts, and the crank linkage is unclear. Clean vector shapes and restrained shading support an appealing illustration with limited physical depth.
