Nemotron 3 Ultra11.9/100

Nemotron 3 Ultra: Newton's Mirror SVG benchmark
Researcher observations

The candidate establishes a separate airborne black blob and partial crimson overlap, but leaves the paint interaction history and settled support unresolved. Its main silhouette, black placement and lamp projection depart substantially from the required camera geometry. A few faint reflection hints provide little support for the extensive mirror system, while the compact paint volumes are visibly disproportionate.

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.

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

Nemotron 3 Ultra41.0/100

Nemotron 3 Ultra: Selfie SVG benchmark
Researcher observations

An endearing mechanical creature is clearly framed, with expressive amber eyes and readable segmented arms. The shell resembles layered green plates more than a deep coiled spiral. Detached-looking construction, absent working contacts and patchy rendering leave the central assembly action substantially unresolved.

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.

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.

Beach

Same prompt

Nemotron 3 Ultra54.8/100

Nemotron 3 Ultra: Beach SVG benchmark
Researcher observations

A recognizable beach illustration with appealing warm-cool contrast, readable layers and mostly clean shapes. Unresolved seat construction, schematic animals and broad geometric foliage give it an elementary finish. Weakly coordinated reflections and limited material differentiation further constrain depth and atmosphere.

Exact prompt

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

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

Same prompt

Nemotron 3 Ultra10.0/100

Nemotron 3 Ultra: Mona Lisa SVG benchmark
Researcher observations

The centered silhouette provides basic organization, but multicolored mottling and geometric overlays leave the portrait unresolved. No readable face, crossed hands, clothing or landscape establishes Mona Lisa replication. Texture and transparency offer limited visual effects without coherent anatomy, lighting or material distinctions.

Exact prompt

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

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

Nemotron 3 Ultra47.3/100

Nemotron 3 Ultra: Raccoon SVG benchmark
Researcher observations

The masked raccoon, dog and orange craft make the scene recognizable, with an appealing sunset palette. Overlapping bodies obscure the riding relationship, and the dog's connection to the controls remains unresolved. Weak water displacement, inconsistent shading and visible shape artifacts limit the finish. Ambiguous attachments do not establish detached limbs or inverted anatomy.

Exact prompt

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.

Nemotron 3 Ultra47.0/100

Nemotron 3 Ultra: Pelican SVG benchmark
Researcher observations

A recognizable, playful pelican dominates a readable bicycle scene. Its bill and silhouette succeed, but feet below the pedals and confused drivetrain connections weaken the riding action. Local material modeling adds interest; overlapping contours, repetitive detail and inconsistent shadows leave the illustration basic and uneven.

Exact prompt

Generate an SVG of a pelican riding a bicycle Make it a masterpiece, no tools allowed

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.
