DeepSeek V4.1 Flash36.4/100

DeepSeek V4.1 Flash: Newton's Mirror SVG benchmark
Researcher observations

The first wall and floor images provide limited reflection geometry, but the room's mirror recurrence is substantially incomplete, particularly the outer-edge chains and lateral sightlines. The main sphere and its large reflected images lack ordered, curved room and virtual-sphere imagery. Repeated emitter mapping is missing from both planar mirrors and spherical surfaces.

Ox Alpha26.4/100

Ox Alpha: Newton's Mirror SVG benchmark
Researcher observations

The setup is recognizable, but the paint interaction remains poorly established and off-center. The first wall and floor images provide coherent placement, scale, silhouette and occlusion cues, with faint lower echoes. Missing receding chains, nested imagery and ordered emitter mappings leave the reflection system heavily simplified. Dull shading does not convincingly depict polished steel or mirrors.

Selfie

Different prompts

DeepSeek V4.1 Flash76.8/100

DeepSeek V4.1 Flash: Selfie SVG benchmark
Researcher observations

The towering ears, glossy eyes, reaching pose and lavender moon create an appealing storybook composition. Limbs connect coherently, and the smaller rabbit adds character. Smooth gradient surfaces provide limited plush fur or padded fabric detail. Broad helmet highlights, weak contact shadows and crowded glowing outlines reduce depth and finish; the moon ring has conspicuously abrupt ends.

Ox Alpha78.0/100

Ox Alpha: Selfie SVG benchmark
Researcher observations

The expressive emerald face, ivory horns, gold accents and fine veining closely match the brief. Rounded volumes and layered shading create an appealing mascot. Rear hoof placement is cramped, lighting is somewhat inconsistent, and conspicuous white patches behind the muzzle interrupt the finish. Surfaces remain visibly stylized rather than photographic.

Beach

Different prompts

DeepSeek V4.1 Flash68.3/100

DeepSeek V4.1 Flash: Beach SVG benchmark
Researcher observations

The glowing sunset, silhouetted palm and playful foreground create a coherent, appealing beach illustration. Birds, crab, boat and reflections fulfill the brief. The airborne animals have weakly defined anatomy and little convincing splash interaction. Broad, blurred reflections and largely flat surfaces limit depth and finish.

Exact prompt

Ox Alpha74.3/100

Ox Alpha: Beach SVG benchmark
Researcher observations

The sunset, framing palms, colorful kite and umbrella create a lively, coherent beach illustration. Birds, animals, splashes and reflections fulfill the brief. Small figures and animals remain schematic, with some interactions difficult to read. Broad reflection bands and soft shadows suggest light without convincing physical detail; flat surfaces limit depth and material richness.

Mona Lisa

Different prompts

DeepSeek V4.1 Flash43.8/100

DeepSeek V4.1 Flash: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, dark hair, crossed hands and muted landscape make the reference recognizable. Replication is limited by the frontal pose, staring eyes and weakly defined smile. Hands are overlapping oval masses with almost no finger articulation, while wrists disappear into sleeves. Soft gradients suggest volume, but broad, indistinct surfaces and faint stray lines leave the drawing basic and uneven.

Exact prompt

Replicate mona-lisa as SVG Make it a masterpiece, no tools allowed

Ox Alpha59.3/100

Ox Alpha: Mona Lisa SVG benchmark
Researcher observations

The crossed arms, green dress and hazy landscape clearly evoke Mona Lisa. Replication is limited by the frontal pose, oversized eyes, elongated face and pronounced lips. Overlapping finger strips lack convincing knuckles and palm volume. The balanced framing and soft shading provide cohesion, but simplified anatomy, repetitive folds and blurred scenery keep the portrait basic.

Raccoon

DeepSeek V4.1 Flash49.0/100

DeepSeek V4.1 Flash: Raccoon SVG benchmark
Researcher observations

The sunset palette and silhouetted grouping establish an appealing scene. A masked rider sits above a pointed-eared dog, but merged body shapes leave limbs and support unresolved. The boatlike craft lacks readable steering controls, so the requested action is unclear. Sparse facial marks and glowing spray dots offer limited detail.

Pelican

Benchmax control

Outside General and Visual Intelligence.

DeepSeek V4.1 Flash76.0/100

DeepSeek V4.1 Flash: Pelican SVG benchmark
Researcher observations

A recognizable pelican rides a brightly colored bicycle against a striking sunset. The sweeping bill, trailing scarf and circular wheels create a controlled composition. Both legs connect, but pedal linkage, body support and the wing's handlebar grip remain loosely resolved. Clean vector shapes and feather details work well; simplified shading limits volume and integration with the sunset light.

Ox Alpha74.8/100

Ox Alpha: Pelican SVG benchmark
Researcher observations

The pelican, bicycle and seaside setting form a clear, appealing illustration. Circular wheels, readable frame tubes and clean silhouettes support the action. The legs connect to the body, but the far foot's pedal contact and wing-to-handlebar junction are cramped. Simple shading, uniform wave marks and limited surface texture keep the rendering relatively flat.
