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.

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

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.

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

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.

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

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.

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

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.

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.

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.

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.
