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.

Qwen 3.8 Flash22.5/100

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

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.

Qwen 3.8 Flash77.8/100

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.

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

Qwen 3.8 Flash73.8/100

Qwen 3.8 Flash: Beach SVG benchmark
Researcher observations

The sunset gradient, sweeping palms and aligned sun reflection create an appealing beach composition. Birds, animals, boating and beach activities satisfy the brief. Small figures and animal anatomy remain rudimentary, water movement is schematic, and contact shadows are weak. Crowded foreground details and a clipped orange disk at the top limit the finish.

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

Qwen 3.8 Flash54.0/100

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.

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.

Qwen 3.8 Flash62.0/100

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

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

Qwen 3.8 Flash73.5/100

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.
