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.

The exact prompt is held back to prevent benchmaxxing.

Kolibri 19.9/100

Kolibri 1: Newton's Mirror SVG benchmark
Researcher observations

A segmented gray perimeter surrounds a black field containing one large, low-positioned gray sphere and two small colored circles. Rounded volume and restrained paint scale earn partial material credit. The image does not demonstrate the required optical structure, while paint history, airborne black and settled support remain largely unresolved.

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.

Kolibri 122.9/100

Kolibri 1: Selfie SVG benchmark
Researcher observations

A restrained ivory, teal and green palette gives the image simple graphic coherence. Execution remains rudimentary: detached oval wings, ambiguous central anatomy and unclear feeding contact prevent a convincing hummingbird scene. The requested feather structure, botanical detail, lighting and enclosing arch are largely unresolved.

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.

Exact prompt

Kolibri 13.3/100

Kolibri 1: Mona Lisa SVG benchmark
Researcher observations

The candidate offers a clean, highly simplified frontal portrait with warm skin and dark hair. Its oversized oval face, schematic features and unresolved body provide little Mona Lisa likeness. Missing crossed hands, clothing detail and landscape remove essential parts of the original composition; smooth gradients supply only limited volume.

Beach

Same prompt

DeepSeek V4.1 Flash59.8/100

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

Create an SVG of a amazing beach scene. Sunset, animals, fun, birds, reflections Make it a masterpiece, no tools allowed

Kolibri 112.9/100

Kolibri 1: Beach SVG benchmark
Researcher observations

A recognizable sunset beach has an appealing purple-orange gradient and clean geometric edges. Birds and animals remain unresolved, terrain obscures the relationship between shore and water, and reflections are absent. Sparse detail, flat materials and limited activity keep the drawing elementary despite its tidy rendering.

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.

Exact prompt

A raccoon sits on a dog's back while the dog steers a jet ski Make it a masterpiece, no tools allowed

Kolibri 110.0/100

Kolibri 1: Raccoon SVG benchmark
Researcher observations

Clean shapes and a readable coral platform provide basic graphic clarity, but the animal construction remains fragmented. A recognizable raccoon riding the dog's back, connected steering and convincing water contact are not demonstrated. Sparse detail, flat subjects and absent movement effects support retaining the baseline category assessments.

Pelican

Benchmax control

Outside General and Visual Intelligence. Excluded from the overall score for DeepSeek V4.1 Flash and Kolibri 1.

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.

Kolibri 135.3/100

Kolibri 1: Pelican SVG benchmark
Researcher observations

Clean shapes and aligned wheels establish a readable schematic scene. Pelican likeness, riding support and bicycle mechanics remain substantially unresolved. Sparse detail and flat surfaces limit expression and volume. Strong edge and fill integrity is a separate success and does not repair the construction.
