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.

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

Gemini 3.8 Flash82.3/100

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.

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.

Beach

Same prompt

Gemini 3.8 Flash75.8/100

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.

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

Different prompts

Gemini 3.8 Flash47.0/100

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 and wrists. Soft shading gives some volume, but muddy transitions, blunt landscape shapes and awkward arm construction weaken the portrait.

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

Gemini 3.8 Flash69.8/100

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.

Qwen3.8 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

Outside General and Visual Intelligence.

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.

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.
