Owl Alpha18.6/100

Owl Alpha: Newton's Mirror SVG benchmark
Researcher observations

Cyan lies on the sphere's facing middle rather than showing its recent interaction near the apex. Separate airborne black and elongated crimson support part of the timing sequence. Small side images and an overlapping lower image provide limited reflection ordering, but recursive room structure, nested imagery and emitter mappings are largely absent. The main sphere is smaller and higher in the frame than prescribed, and the surfaces have a soft, matte appearance.

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

Owl Alpha62.0/100

Owl Alpha: Selfie SVG benchmark
Researcher observations

Amber slit eyes, a pointed beak, cream feathers and gold-trimmed black clothing establish the secretive owl rogue. The head appears frontal rather than lowered, with much of the face exposed. The centered silhouette is effective, but stiff cloak geometry, shallow facial modeling and extremely dark clothing limit depth and finish. Sparse gold markings suggest the requested circuitry only loosely.

Qwen 3.8 Flash72.8/100

Qwen 3.8 Flash: Selfie SVG benchmark
Researcher observations

The towering ears, expressive eyes, astronaut suit and diagonal moon ring create an appealing storybook scene. The reaching arm connects coherently to the carrot interaction. Smooth surfaces provide little plush fur, crater depth is simplified, and bright granular fringes roughen the rings and floating rocks. One small rabbit paw appears detached beneath its body.

Beach

Different prompts

Owl Alpha60.3/100

Owl Alpha: Beach SVG benchmark
Researcher observations

The sunset, palms, birds and beach animals create a cheerful, readable scene. Clean silhouettes and a vivid sky establish the composition, but construction remains schematic. The right palm appears rooted in open water, shadows have limited connection to the sunset, and the sun’s reflection consists of rigid bands. Small creatures and beach equipment are recognizable but minimally developed.

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

Different prompts

Owl Alpha32.5/100

Owl Alpha: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, slight smile, overlapping hands and distant landscape suggest Mona Lisa, but replication is weak. The face has little volume, the shoulders and torso form a narrow wedge, and the hands are fingerless ovals with unresolved wrists. Broad gray background bands provide limited depth. A bright head rim and pale hands contrast with an almost featureless dark figure.

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

Different prompts

Owl Alpha52.3/100

Owl Alpha: Raccoon SVG benchmark
Researcher observations

The raccoon is recognizable and expressive, with a clear mask and striped tail. The dog's anatomy is poorly resolved, and the flattened craft lacks convincing steering and seating. Feet extend below the hull, weakening the sense of support. An appealing palette, clean shapes and decorative water effects give the illustration some polish.

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.

Owl Alpha79.0/100

Owl Alpha: Pelican SVG benchmark
Researcher observations

A clearly recognizable pelican cycles through a well-composed coastal sunset. Warm colors, flowing scarf, feather contours and bicycle details give the illustration character. The legs connect to the body, but the farther foot's pedal contact and the wing's handlebar grip remain ambiguous. Clean vector shapes provide polish, with limited material texture and directional shading.

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.
