Gemini 3.8 Flash25.0/100

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.

Kimi K332.8/100

Kimi K3: Newton's Mirror SVG benchmark
Researcher observations

The room fills the complete portrait frame without visible borders or labels. The main sphere and airborne black are convincingly placed within the portrait frame. Paint ordering is supported, but its contact and transport history remains weakly expressed. Symmetric wall ghosts, inverted floor imagery and panel echoes establish a basic mirror system. Diffuse gradients dominate, with little ordered nested imagery or repeated emitter mapping on either planar or spherical surfaces. The wall images sit too low, and the floor image is unusually large and low.

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.

Kimi K377.5/100

Kimi K3: Selfie SVG benchmark
Researcher observations

The indigo creature and warm reflected counterpart create a balanced, contemplative composition. Equations, constellations and book emblems give the transformation meaning. Clean silhouettes and controlled glow support the scene, but minimally articulated legs, shallow spatial cues and smooth, generalized surfaces limit its anatomical and material richness.

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.

Kimi K373.3/100

Kimi K3: Beach SVG benchmark
Researcher observations

The sunset, animals, birds, beach toys and reflections fulfill the brief in a lively, readable composition. Clean silhouettes and a rich sky provide appeal. Bodies and people remain diagrammatic, depth is shallow, and the inverted figure reflections cross matte-looking sand without convincing surface lighting. Materials and movement are mostly conveyed through flat shapes.

Mona Lisa

Same prompt

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.

Kimi K348.5/100

Kimi K3: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, dark veil, folded hands and misty landscape clearly evoke Mona Lisa. Replication is limited by the elongated neck, simplified facial proportions and oval hands with shallow finger marks. Soft shading gives some volume, but pervasive blur substitutes for controlled painterly transitions and precise detail.

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.

Kimi K376.3/100

Kimi K3: Raccoon SVG benchmark
Researcher observations

The raccoon rides on the dog's back, and the dog's paw meets a steering assembly connected to the red hull. Expressive faces, a warm sunset and sweeping spray create an appealing composition. Crowded body overlaps obscure some limb connections, and the raccoon's right ear appears slightly separated. Flat shading and stylized reflections limit volume and depth.

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.

Kimi K372.8/100

Kimi K3: Pelican SVG benchmark
Researcher observations

The pelican and bicycle are immediately recognizable, with an expressive bill, flowing scarf and cheerful composition. Both legs remain attached, but pedal connections and wing contact with the handlebar are weakly resolved. Wheel alignment and landscape layers are coherent. Clean outlines support the illustration, while flat surfaces and limited lighting keep it short of masterful execution.
