Physics, perspective and recursive reflections, tested together. Explore the test ↗

Glyph Cluster13.8/100

Glyph Cluster: Newton's Mirror SVG benchmark
Researcher observations

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.

Simplified prompt

A shiny steel ball spins in a room with mirrored walls and a mirrored floor. Red, cyan and black paint float above it. Gravity suddenly switches on. Draw the scene a moment later, as the ball drops and paint begins landing on its spinning surface. Show the reflections repeating through the room.

Qwen 3.8 Flash25.1/100

Qwen 3.8 Flash: Newton's Mirror SVG benchmark
Researcher observations

The full-frame illustration supports a central steel sphere, an airborne black blob and the relative ordering of cyan and crimson. Its faint floor return and symmetric repetitions provide sparse mirror structure; outer chains, large reflected images, nested imagery and emitter mapping remain deficient. Vertical framing is substantially displaced, and paint contact histories remain unresolved.

Selfie

Different prompts

Glyph Cluster32.4/100

Glyph Cluster: Selfie SVG benchmark
Researcher observations

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.

Qwen 3.8 Flash76.4/100

Qwen 3.8 Flash: Selfie SVG benchmark
Researcher observations

A coherent, appealing fantasy illustration with disciplined framing, luminous teal accents and consistent ornament. Most requested elements are clearly present. The bear-like facial proportions, lowered resting hand, obscured bent-leg construction and limited fabric modeling constrain likeness and anatomical clarity; glow effects are attractive but weakly integrated with surrounding surfaces.

Simplified prompt

Draw a friendly capybara floating in ornate green and white robes. A glowing halo and small floating orbs surround it, giving it the feel of a gentle fantasy guide.

Mona Lisa

Different prompts

Glyph Cluster11.7/100

Glyph Cluster: Mona Lisa SVG benchmark
Researcher observations

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.

Qwen 3.8 Flash51.9/100

Qwen 3.8 Flash: Mona Lisa SVG benchmark
Researcher observations

The dark dress, crossed hands and hazy landscape evoke the Mona Lisa, but replication is limited by a generic frontal face, coarse smile and poorly articulated fingers. The gold frame has clearer definition than the portrait. Heavy mottling obscures features, while soft shading provides some volume without convincing anatomical detail.

Beach

Different prompts

Glyph Cluster44.1/100

Glyph Cluster: Beach SVG benchmark
Researcher observations

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.

Exact prompt

Qwen 3.8 Flash77.4/100

Qwen 3.8 Flash: Beach SVG benchmark
Researcher observations

Sweeping palms, coordinated sunset colors and a central reflection create an expressive beach composition with clear depth. Birds, animals and varied activities thoroughly realize the brief. Small figures and animal anatomy remain rudimentary, water movement is schematic, and contact shadows are weak. Scattered foreground details and the clipped orange disk limit the finish.

Ground Truth

Same prompt

Glyph Cluster: Ground Truth SVG benchmark
Simplified prompt

A dark steel room has four pillars and two warm ceiling lights. A wooden plank is placed over a computer mouse, with a blueberry on the plank above it. Draw the scene a few seconds later, showing how the objects settle and how the light, shadows and surfaces look.

Raccoon

Different prompts

Glyph Cluster43.6/100

Glyph Cluster: Raccoon SVG benchmark
Researcher observations

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.

Exact prompt

Qwen 3.8 Flash62.4/100

Qwen 3.8 Flash: Raccoon SVG benchmark
Researcher observations

The raccoon clearly rides the dog's back, with expressive features and appealing blue-orange color contrast. The dog's paws do not clearly operate connected controls, and the shallow vehicle lacks convincing jet ski construction. Clean outlines support the cartoon style, but generic shading and blurred water streaks limit depth and motion.

Pelican

Benchmax control

Outside General and Visual Intelligence. Excluded from the overall score for Glyph Cluster and Qwen 3.8 Flash.

Glyph Cluster44.3/100

Glyph Cluster: Pelican SVG benchmark
Researcher observations

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.

Qwen 3.8 Flash77.5/100

Qwen 3.8 Flash: Pelican SVG benchmark
Researcher observations

The pelican's expressive face, oversized bill and flowing scarf create an appealing focal point. The bicycle has recognizable frame, chain and wheel construction, but the far foot lacks a clear pedal connection and the wing's steering contact is ambiguous. Clean contours and gentle gradients support the illustration; simplified volume and weak directional shadows limit depth.
