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.

Ling 3.1 Flash39.6/100

Ling 3.1 Flash: Newton's Mirror SVG benchmark
Researcher observations

Central placement, separate airborne black paint and the elongated crimson coating earn substantial state and placement credit. Cyan contact remains unresolved. A few isolated sphere images provide limited optical evidence, while the defining repeated mirror structure is missing. Readable opaque metallic volume and restrained paint scale justify increased material credit. Core: 61.5/170; including the floor reward: 61.5/180.

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.

Ling 3.1 Flash77.0/100

Ling 3.1 Flash: Selfie SVG benchmark
Researcher observations

An appealing, coherent storybook ant with a clear expression, complete silhouette and readable signal mechanism. Clean curves and warm accents support the composition, while simplified joints, schematic hardware, limited material differentiation and modest light interaction constrain its finish.

Mona Lisa

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

Ling 3.1 Flash24.0/100

Ling 3.1 Flash: Mona Lisa SVG benchmark
Researcher observations

A basic, uneven Mona Lisa interpretation with a clear facial focal point, articulated eyes and modest tonal volume. Weak likeness, oversized head proportions, unclear shoulders, curled bare arms and indistinct hands limit replication. The compressed composition and rectangular torso weaken an otherwise coherent earthy palette.

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

Ling 3.1 Flash65.7/100

Ling 3.1 Flash: Beach SVG benchmark
Researcher observations

A coherent sunset illustration with harmonious color, clean silhouettes and readable beach details. Its calm composition works well, while playful activity is modest. Simplified animal anatomy, shallow shoreline layering, repetitive foliage and a geometric reflection limit drawing sophistication and naturalism.

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.

Ling 3.1 Flash63.1/100

Ling 3.1 Flash: Raccoon SVG benchmark
Researcher observations

An appealing sunset cartoon with recognizable animals, expressive faces and coherent landscape layers. The sky and warm water streaks provide its strongest rendering. Ambiguous seated support, stiff forelegs, a shallow hull and an unclear steering connection limit construction. Clean shapes and readable accessories add finish, while restrained spray and flat surfaces limit material and motion effects.

Pelican

Benchmax control

Outside General and Visual Intelligence. Excluded from the overall score for Gemini 3.8 Flash and Ling 3.1 Flash.

Gemini 3.8 Flash76.3/100

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.

Ling 3.1 Flash70.0/100

Ling 3.1 Flash: Pelican SVG benchmark
Researcher observations

A clean, appealing pelican illustration with a readable bicycle and coherent landscape. Bill shading, feather layers and faint wheel shadows provide modest depth. Uncertain pedal contact, simplified leg construction and limited material rendering keep the result within competent illustration quality.
