DeepSeek V4.1 Flash43.3/100

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.

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.

Qwen3.6 35B A3B: Newton's Mirror SVG benchmark
Researcher observations

The artwork demonstrates rounded volume, recognizable paint colors and a compact black feature at an appropriate screen height. The enlarged main-sphere framing, unsupported crimson and cyan interaction histories, oversized compact paint balls and largely missing mirror structure remain substantial weaknesses. The core assessment is 20/170; with no demonstrated floor damage, the combined assessment remains 20/180.

Selfie

Different prompts

DeepSeek V4.1 Flash63.4/100

DeepSeek V4.1 Flash: Selfie SVG benchmark
Researcher observations

Expressive faces, cobalt coloring and a flowing diagonal composition make the mutual inspection charming. Execution is uneven: the long pointed flipper lacks a convincing grip, the enlarged shrimp face appears detached from its body, and the large lens is oval. Flat anatomical shading and an unexplained purple ringed patch beneath the whale weaken the requested polished depth.

Simplified prompt

Draw a curious blue whale examining a tiny shrimp through a bubble magnifying glass. The shrimp looks back through its own smaller bubble lens. An octopus assistant sits on the whale's head while rising bubbles lift a little seaweed wig above it.

Qwen3.6 35B A3B: Selfie SVG benchmark
Researcher observations

An appealing fantasy illustration with coordinated ornament, readable suspension and luminous turquoise accents. Plausible limb attachments and soft shading support competent execution. Bear-like proportions, unclear paw gestures, insufficient white robe fabric, crowded chest details and shallow material modeling limit its finish.

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

Same prompt

DeepSeek V4.1 Flash37.5/100

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.

A recognizable but basic geometric interpretation. Muted colors and soft shading provide cohesion, while weak likeness, unresolved hands, rigid anatomy and shallow landscape construction substantially limit the replication.

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.

A recognizable beach sunset with balanced framing and appealing color transitions. Birds, boats and small animals fulfill the main scene requirements. Elementary anatomy, faint details, weak grounding and rigid reflection columns limit depth and finish.

Raccoon

Different prompts

DeepSeek V4.1 Flash43.4/100

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.

Qwen3.6 35B A3B51.9/100

Qwen3.6 35B A3B: Raccoon SVG benchmark
Researcher observations

Clean shapes, cheerful faces and bright colors make the riding arrangement readable. The dog does not visibly operate the control, while awkward limbs, shallow hull placement and stiff poses limit credibility. Gradients and layered foam add modest volume and motion. The obscured tail attachment does not establish detachment.

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for DeepSeek V4.1 Flash and Qwen3.6 35B A3B.

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.

Qwen3.6 35B A3B61.5/100

Qwen3.6 35B A3B: Pelican SVG benchmark
Researcher observations

A cheerful, readable illustration with a distinctive pelican silhouette, clean contours and an orderly landscape. Soft glow and restrained shading provide modest atmosphere. Construction is weaker: the handlebar is disconnected, wings do not reach the controls, and overlapping legs leave pedaling ambiguous. Simple forms and mostly flat materials limit depth and drawing sophistication.
