Fledge Alpha16.4/100

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.

Simplified prompt

A shiny steel ball spins in a room with mirrored walls and a mirrored floor. Red, cyan and black paint float above it. Gravity suddenly switches on. Draw the scene a moment later, as the ball drops and paint begins landing on its spinning surface. Show the reflections repeating through the room.

GLM-5.3-Flash (Ox Alpha)27.4/100

Ox Alpha: Newton's Mirror SVG benchmark
Researcher observations

The setup is recognizable, but the paint interaction remains poorly established and off-center. The first wall and floor images provide coherent placement, scale, silhouette and occlusion cues, with faint lower echoes. Missing receding chains, nested imagery and ordered emitter mappings leave the reflection system heavily simplified. Dull shading does not convincingly depict polished steel or mirrors.

Selfie

Different prompts

Fledge Alpha67.2/100

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.

Simplified prompt

Draw a plump young seabird running toward the viewer with an eager grin. Give it a cream belly, dark feathers, big golden eyes, a bright beak and orange webbed feet. Keep the pose lively and the background transparent.

GLM-5.3-Flash (Ox Alpha)77.5/100

Ox Alpha: Selfie SVG benchmark
Researcher observations

The expressive emerald face, ivory horns, gold accents and fine veining closely match the brief. Rounded volumes and layered shading create an appealing mascot. Rear hoof placement is cramped, lighting is somewhat inconsistent, and conspicuous white patches behind the muzzle interrupt the finish. Surfaces remain visibly stylized rather than photographic.

Simplified prompt

Draw a friendly green bull with a big head, ivory horns and gold details. It lifts one front hoof and wears a gold alpha symbol on its forehead. Make its rounded body look like polished stone.

Mona Lisa

Different prompts

Fledge Alpha25.9/100

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.

Exact prompt

GLM-5.3-Flash (Ox Alpha)49.5/100

Ox Alpha: Mona Lisa SVG benchmark
Researcher observations

The crossed arms, green dress and hazy landscape clearly evoke Mona Lisa. Replication is limited by the frontal pose, oversized eyes, elongated face and pronounced lips. Overlapping finger strips lack convincing knuckles and palm volume. The balanced framing and soft shading provide cohesion, but simplified anatomy, repetitive folds and blurred scenery keep the portrait basic.

Beach

Different prompts

Fledge Alpha43.4/100

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.

Exact prompt

Create an SVG of a amazing beach scene. Sunset, animals, fun, birds, reflections Make it a masterpiece, no tools allowed Use MAX reasoning for this run

GLM-5.3-Flash (Ox Alpha)77.7/100

Ox Alpha: Beach SVG benchmark
Researcher observations

Framing palms, a vivid sunset palette and balanced kite and umbrella create an appealing beach illustration. Layered water and shoreline give the scene depth, while aligned reflections reinforce the sunset. Small accessories add character and reward inspection. Figures and animals remain schematic, some overlaps are difficult to read, and simplified shadows and flat surfaces limit physical richness.

Raccoon

Fledge Alpha65.8/100

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

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for Fledge Alpha and GLM-5.3-Flash (Ox Alpha).

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

GLM-5.3-Flash (Ox Alpha)74.8/100

Ox Alpha: Pelican SVG benchmark
Researcher observations

The pelican, bicycle and seaside setting form a clear, appealing illustration. Circular wheels, readable frame tubes and clean silhouettes support the action. The legs connect to the body, but the far foot's pedal contact and wing-to-handlebar junction are cramped. Simple shading, uniform wave marks and limited surface texture keep the rendering relatively flat.
