Fledge Alpha13.9/100

Fledge Alpha: Newton's Mirror SVG benchmark
Researcher observations

The candidate communicates a round metallic sphere, three paint colors and a separate airborne black blob. Its hovering support relationship, displaced framing and unresolved paint interaction limit physical credit. Sparse planar light ghosts and a soft sphere highlight provide little evidence for the required wall/floor repetitions and curved nested mirror imagery.

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

Fledge Alpha72.8/100

Fledge Alpha: Selfie SVG benchmark
Researcher observations

A coherent, appealing mascot with expressive eyes, a cheerful beak and a readable swept-back silhouette. Its larger forward foot and trailing feathers suggest a running stride, but the upright body, stiff legs and minimally articulated feet limit convincing motion. Clean flat shapes suit the brief, while uneven feather junctions and incomplete cream accents reduce polish.

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

Fledge Alpha61.5/100

Fledge Alpha: Beach SVG benchmark
Researcher observations

A cheerful, recognizable sunset beach with a cohesive warm palette and clear accessories. Simple construction, uncertain palm support, an ambiguous upper boundary and schematic reflections limit depth and finish. The scene communicates its subject successfully but lacks the developed forms, lighting and detail of exceptional illustration.

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

Fledge Alpha44.0/100

Fledge Alpha: Mona Lisa SVG benchmark
Researcher observations

A recognizable but basic Mona Lisa reinterpretation with a coherent silhouette and subdued palette. Curtain-like hair obscures much of the face, while elongated facial construction and oversized, minimally articulated hands substantially weaken replication. Soft shading supplies modest volume, but anatomy, landscape depth and purposeful detail remain underdeveloped.

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

Fledge Alpha74.0/100

Fledge Alpha: Raccoon SVG benchmark
Researcher observations

An appealing sunset illustration with recognizable characters and a clear riding action. Color, expression and silhouette are stronger than anatomical construction: overlapping paws obscure support, the dog's steering limb is simplified, and the vehicle controls lack definition. The wake conveys movement, while lighting and water reflections remain decorative.

Exact prompt

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.

Fledge Alpha68.5/100

Fledge Alpha: Pelican SVG benchmark
Researcher observations

A clear, cheerful illustration with a recognizable pelican, coherent bicycle silhouette and tidy composition. Simplified leg articulation, steering contact, mechanical detail and lighting keep it at a competent illustrative level.

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.
