Space Bunny Alpha: Newton's Mirror SVG benchmark
29 Sep onwardResult details ↗
Researcher observations

Visible panel shapes, curved sphere highlights, rounded side images and a lower continuation beneath the large left image establish recognizable local mirror structure. Their uneven arrangement, missing receding chains and absent nested imagery remain substantial shortcomings. The main sphere's framing is close, but black lacks projected separation and cyan does not establish recent apex contact.

Union Alpha38.3/100

Union Alpha: Newton's Mirror SVG benchmark
Researcher observations

Recognizable near-field sphere placement and bilateral convergence provide limited optical structure. Broad gray regions interrupt lateral sightlines and truncate side-floor images. Missing outer chains, absent nested sphere imagery and incomplete planar and curved emitter mappings dominate the reflection system.

Space Bunny Alpha: Selfie SVG benchmark
29 Sep onwardResult details ↗
Researcher observations

The expressive rabbits, lavender moon and diagonal ring create an appealing storybook composition with nearly all requested features. Glossy eyes and pearly highlights work well. The helmet leaves the towering ears unenclosed, the reaching arm has little joint definition, and the spread boots suggest hovering more clearly than pushing off. Repeated scalloped fur marks and broad gradients limit material depth; purple edge halos soften otherwise controlled silhouettes.

Beach

Same prompt

Space Bunny Alpha74.0/100

Space Bunny Alpha: Beach SVG benchmark
29 Sep onwardResult details ↗
Researcher observations

A cheerful, coherent beach illustration with a strong sunset focal point, varied animals and readable small accessories. Connected flamingo legs and grounded foreground objects support the scene. Construction remains schematic, especially the airborne marine animal; its jump lacks clear water displacement. The sun reflection is effective but geometrically rigid, while shadows and material textures provide limited depth.

Exact prompt

Create an SVG of a amazing beach scene. Sunset, animals, fun, birds, reflections

Union Alpha80.0/100

A beach at sunset with a palm tree, turtle, crab, birds, and a leaping dolphin.
Researcher observations

A cohesive sunset palette, sweeping shoreline and playful animals make an appealing beach illustration. The sun’s reflection establishes a clear focal axis, balanced by the palm and umbrella. Clean silhouettes and small decorative features reward inspection, though simplified anatomy, repetitive reflection bars and generic oval shadows limit volume and naturalism.

Mona Lisa

Same prompt

Space Bunny Alpha57.3/100

Space Bunny Alpha: Mona Lisa SVG benchmark
29 Sep onwardResult details ↗
Researcher observations

The dark clothing, folded hands and muted landscape make the reference recognizable. Replication is limited by the broad frontal face, oversized head, explicit smile and simplified landscape. Arms connect coherently, but overlapping hands lack convincing finger construction. Soft gradients suggest volume and atmospheric depth; clothing folds and facial features remain schematic.

Exact prompt

Replicate mona-lisa as SVG

Union Alpha64.0/100

An SVG interpretation of the Mona Lisa, with folded hands and a landscape background.
Researcher observations

The centered portrait, folded hands, dark clothing and hazy landscape clearly evoke the Mona Lisa. Muted colors and soft facial shading create a coherent illustration, but replication remains schematic: the face is broad, eyes outlined, smile simplified and overlapping fingers poorly resolved. Angular landscape shapes and flat fabric limit depth and painterly richness.

Space Bunny Alpha: Raccoon SVG benchmark
Before 29 SepResult details ↗
Researcher observations

The raccoon clearly rides on the dog's back, and the dog's paws reach a connected steering assembly. Expressive faces, controlled outlines and layered mountains make an appealing illustration. The seated anatomy and hull geometry are simplified, while the sunset has little corresponding reflection or directional shading. Curved spray conveys motion, although several splash ribbons look decorative.

Exact prompt

A raccoon sits on a dog's back while the dog steers a jet ski Make it a masterpiece

Union Alpha72.0/100

A raccoon rides on a dog as the dog steers a red jet ski.
Researcher observations

Expressive animals, a readable riding arrangement and sweeping spray create an appealing cartoon. The raccoon sits convincingly on the dog's back, but the dog's paw does not clearly grip the handlebar, whose connection to the hull is unresolved. Flat lighting provides little volume or reflection. A dark rectangular strip interrupts the upper-right background.

Space Bunny Alpha: Pelican SVG benchmark
29 Sep onwardResult details ↗
Researcher observations

The large pouched bill clearly identifies the pelican, and the balanced bicycle silhouette makes the action readable. Attached legs reach the crank area, but overlapping feet and crank lines leave pedal contact ambiguous. Consistent wheel scale, clean contours and a restrained coastal palette support an appealing composition. Lighting and surface treatment remain simple and mostly flat.

Exact prompt

Generate an SVG of a pelican riding a bicycle For this specific task your token limit is increased to 80,000 Juice: 2048

Union Alpha73.8/100

A pelican riding a teal bicycle beneath a sunny blue sky.
Researcher observations

The pelican is immediately recognizable, with an expressive face, convincing bill silhouette and appealing pastel composition. Both legs connect to feet, and the wing reaches the handlebar. Bicycle construction is less resolved: the far pedal lacks a clear crank connection and no chain is visible. Clean contours and orderly spokes support the illustration, while flat lighting and simplified surfaces limit depth.
