Gemini 3.8 Flash30.3/100

Gemini 3.8 Flash: Newton's Mirror SVG benchmark
Researcher observations

Crimson is carried well down the camera-facing surface, supporting its earlier interaction. The depiction remains highly simplified, with imperfect material rendering. Isolated wall and floor images and a few highlights provide scant reflective evidence; displaced first reflections, missing receding chains and absent nested sphere and emitter imagery leave the room's optical structure largely unsupported.

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 27b: Newton's Mirror SVG benchmark
Researcher observations

The artwork depicts a shaded sphere, distinct paint colors and a separate airborne black blob. Crimson's apex overlap does not establish its earlier interaction and transport, while cyan's recent contact remains unsupported. Horizontal centering supplies limited camera agreement, but the sphere, black blob and prominent panel have substantial placement or projection departures. A few planar echoes provide reflection evidence; isolated patches and gradients replace most of the required mirror structure.

Selfie

Different prompts

Gemini 3.8 Flash77.0/100

Gemini 3.8 Flash: Selfie SVG benchmark
Researcher observations

The dominant four-point silhouette, luminous color progression, raised brows and enormous grin closely fulfill the brief. Attached, secondary limbs support the exuberant expression. Clean facial drawing and glossy eyes give strong character, while shallow depth, minimally articulated extremities and visible steps in the outer glow limit refinement.

Simplified prompt

Draw a glowing four-point star creature with big eyes and an exaggerated grin. Blend blue, purple and pink across its body and add a few tiny sparkles. Keep its star shape easy to recognize.

Qwen3.6 27b56.3/100

Qwen3.6 27b: Selfie SVG benchmark
Researcher observations

An appealing decorative illustration with coordinated ornament, flowing panels and three glowing orbital lights. The arm arrangement reverses the requested sides. Uncertain neck continuity, concealed leg articulation, simplified paws, crowded chest jewelry and shallow surface modeling limit pose clarity and 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

Different prompts

Gemini 3.8 Flash29.8/100

Gemini 3.8 Flash: Mona Lisa SVG benchmark
Researcher observations

The dark clothing, overlapping hands and hazy landscape make the Mona Lisa reference recognizable. Replication is limited by the frontal, elongated face, heavy mouth and chin, and poorly resolved hands, wrists and forearm. Soft shading gives some volume, but muddy transitions, blunt landscape shapes and rigid facial modeling weaken the portrait’s expression and painterly character.

Exact prompt

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

Qwen3.6 27b30.8/100

Qwen3.6 27b: Mona Lisa SVG benchmark
Researcher observations

The portrait loosely evokes Mona Lisa through its palette and silhouette. Readable pupils, brows and lips provide limited detail, and the torso remains continuous. The frontal elongated face, unresolved chest-level limb forms, shallow landscape and pervasive blur substantially weaken likeness, anatomy and finish.

Beach

Same prompt

Gemini 3.8 Flash75.1/100

Gemini 3.8 Flash: Beach SVG benchmark
Researcher observations

A vivid purple-and-gold sunset anchors an appealing beach composition with dolphins, birds, a turtle and playful accessories. Palm silhouettes frame the bright reflection effectively. Sparse animal anatomy, wirelike palm foliage, conspicuously regular reflection bands and limited surface texture keep the execution below exceptional.

Exact prompt

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

Qwen3.6 27b56.7/100

Qwen3.6 27b: Beach SVG benchmark
Researcher observations

A recognizable sunset beach with balanced palms, clean shapes and effective warm–cool contrast. Small animals and play equipment address the brief, but rudimentary anatomy, uncertain water contacts, sparse reflections and flat materials keep the drawing basic or uneven.

Raccoon

Same prompt

Gemini 3.8 Flash68.4/100

Gemini 3.8 Flash: Raccoon SVG benchmark
Researcher observations

Expressive animals, a bold diagonal hull and sweeping spray create an appealing action scene. The raccoon's support on the dog's back is unclear, and the dog lacks a readable paw-to-control grip and connected steering assembly. Clean graphic shapes and lively accessories are stronger than the anatomical construction. Sunset illumination and reflections remain largely decorative.

Qwen3.6 27b57.7/100

Qwen3.6 27b: Raccoon SVG benchmark
Researcher observations

A readable cartoon with balanced colors, clean shapes and a clearly supported raccoon. Continuous body construction and modest shading deserve credit. Rudimentary limbs, unresolved steering connections, stiff gestures and schematic water effects limit physical credibility and finish.

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for Gemini 3.8 Flash and Qwen3.6 27b.

Gemini 3.8 Flash78.8/100

Gemini 3.8 Flash: Pelican SVG benchmark
Researcher observations

The pelican’s enormous bill, lively feathers and orange bicycle create a clear, appealing composition. Basket contents, spokes and facial details reward inspection. Both legs connect to the body, but foot-to-pedal placement and wing-to-handlebar contact are ambiguous. Bicycle mechanics and lighting remain schematic, limiting an otherwise polished illustration.

Qwen3.6 27b58.5/100

Qwen3.6 27b: Pelican SVG benchmark
Researcher observations

A lively, coherent illustration with recognizable pelican features, purposeful accessories and useful surface variation. Ambiguous neck layering, uncertain pedal engagement and an unresolved drivetrain limit construction. Aligned wheels and layered scenery establish placement, while inconsistent shadow direction and crowded overlaps constrain finish.
