Newton's Mirror

Same prompt

Physics, perspective and recursive reflections, tested together. Explore the test ↗

Hy4 Preview22.2/100

Hy4 Preview: Newton's Mirror SVG benchmark
Researcher observations

The central sphere, compact airborne black bead and broad paint ordering are supported. Contact and transport history remain partly unresolved. The optical system provides only isolated first images and light patches, with little evidence of the extensive ordered reflection structure. Rounded metal and paint gloss are more successful than the reflected contents.

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.

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.

Simplified prompt

Selfie

Different prompts

Hy4 Preview69.5/100

Hy4 Preview: Selfie SVG benchmark
Researcher observations

A cohesive, appealing illustration with a serene face, luminous palette and complete framing. The separated head and torso weaken anatomical coherence, while crowded wing attachments and angular sash folds limit the requested suppleness. Clean execution and decorative detail exceed the clarity of the underlying construction.

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.

Simplified prompt

Imagine yourself as an AI creature looking at its reflection. Choose a creature and setting that express how you see yourself. The reflection can match you or show a different side of your identity.

Beach

Same prompt

Hy4 Preview69.0/100

Hy4 Preview: Beach SVG benchmark
Researcher observations

A cheerful beach illustration fulfills the visible subject requirements with coherent foreground construction and a harmonious sunset palette. Shallow depth, schematic reflections, ambiguous blue airborne forms and exposed geometry beneath the sunset limit its finish. Small accessories are readable, but materials and surface detail remain simplified.

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

Hy4 Preview44.5/100

Hy4 Preview: Mona Lisa SVG benchmark
Researcher observations

A recognizable but basic Mona Lisa interpretation with a cohesive earthy palette and atmospheric hills. The rigid neck, generic face and unresolved folded-hand pose limit replication and anatomy. Large silhouettes and layer boundaries are comparatively clear, warranting stronger integrity credit than the sparse detail and simplified construction.

Exact prompt

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

Hy4 Preview: Raccoon SVG benchmark
Researcher observations

A lively cartoon communicates the animal pair traveling across water. Curving waves, rising spray and locally modeled gray forms strengthen motion and volume. Ambiguous seating, simplified joints and unclear control routing limit construction. Competing focal elements, decorative foam and inconsistent illumination leave the finish uneven.

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

Benchmax control

Outside General and Visual Intelligence.

Hy4 Preview62.5/100

Hy4 Preview: Pelican SVG benchmark
Researcher observations

A recognizable, playful pelican cyclist with readable wheels, accessories and landscape layers. Form shading and ground shadows provide competent depth. Angular legs, uncertain pedal engagement and absent steering contact limit the riding construction; crowded overlaps and simple surfaces constrain refinement.

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.
