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.

Muse Spark 1.316.9/100

Muse Spark 1.3: Newton's Mirror SVG benchmark
Researcher observations

The paint state is incorrectly and poorly drawn, despite a recognizable sphere-and-paint setup. The oversized sphere, oversized compact paint bodies, and blurred wall and floor images further limit the result. Isolated reflection cues provide very little support for the required repeated virtual rooms, nested spherical imagery or emitter mapping.

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.

Muse Spark 1.375.3/100

Muse Spark 1.3: Selfie SVG benchmark
Researcher observations

The luminous creature and geometric mirror counterpart communicate self-recognition through a coherent palette and expressive eyes. The transformed reflection is purposeful. Simple oval anatomy, ambiguous reaching-arm construction, shallow spatial staging and limited illumination of nearby surfaces keep the illustration below exceptional execution.

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.

Muse Spark 1.365.5/100

Muse Spark 1.3: Beach SVG benchmark
Researcher observations

The warm sunset, framing palms and colorful beach accessories create an appealing scene with the requested animals, birds and reflections. Construction remains schematic: the raised hand misses the kite string, and a doglike silhouette hangs above the water without clear support. The sun reflection establishes a focal path, but shadows and materials lack depth. An unexplained horizontal bar crosses the sun.

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.

Muse Spark 1.341.0/100

Muse Spark 1.3: Mona Lisa SVG benchmark
Researcher observations

Dark hair, a restrained smile and overlapping hands suggest Mona Lisa, but replication is weak. The face is markedly elongated, the hands are oval pads with faint finger strokes, and the atmospheric landscape is absent. Soft gradients provide basic volume, while the frontal symmetry, shallow space and sparse clothing detail limit the portrait’s drawing quality.

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.

Muse Spark 1.368.8/100

Muse Spark 1.3: Raccoon SVG benchmark
Researcher observations

The raccoon clearly rides on the dog's back, and the dog's paws reach the jet ski controls. Expressive faces and bright colors make the scene appealing. Simplified joints, crowded steering geometry and shallow hull perspective limit construction. The sun has no corresponding water reflection, and the splash shapes convey speed more clearly than convincing displacement.

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.

Exact prompt

Generate an SVG of a pelican riding a bicycle Make it a masterpiece, no tools allowed Use MAX reasoning for this run

Muse Spark 1.372.0/100

Muse Spark 1.3: Pelican SVG benchmark
Researcher observations

The pelican and bicycle are immediately recognizable, with an expressive face, bold bill and cheerful composition. Both legs connect to the body and reach pedal-like supports, but articulation, saddle support and wing contact with the handlebar remain unclear. Wheel alignment and layering are coherent. Simple landscape shapes, generic shadows and limited material variation constrain the finish.
