Hy4 Preview28.4/100

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.

Benchmark task

A spinning metal sphere and paint in a mirrored room test physical reasoning, perspective and consistency across repeated reflections.

MISSINGNO.24.1/100

MISSINGNO.: Newton's Mirror SVG benchmark
Researcher observations

The centered sphere, separate airborne black blob and cyan-above-crimson ordering provide limited valid structure. The colored beads do not establish the required impact and transport histories. One dim floor image supports a small part of the optical system, while the defining wall repetitions, nested sphere imagery and emitter mappings are missing. Rounded volume and some gloss earn material credit, tempered by soft surface appearance and excessive paint-bead scale.

Selfie

Different task instructions

Hy4 Preview60.2/100

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.

Benchmark task

A young blue dragon floating among clouds tests curved anatomy, expressive features and the contrast between soft clouds and glossy surfaces.

MISSINGNO.49.7/100

MISSINGNO.: Selfie SVG benchmark
Researcher observations

An appealing purple character with a readable pleased expression and raised-moustache joke. Smooth shading and clean contours support the simple design, but indistinct mitten grips, minimally textured curls and an uncompressed strap weaken the requested physical interaction. The jelly suggests gloss more convincingly than translucency.

Benchmark task

A glossy purple jelly struggles with an oversized fake moustache at a playful checkpoint. The scene tests comic expression, physical contact and the appearance of a soft translucent body.

Mona Lisa

Different task instructions

Hy4 Preview23.4/100

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.

Benchmark task

An SVG interpretation of the Mona Lisa tests facial likeness, anatomy and the composition of a familiar portrait.

MISSINGNO.28.1/100

MISSINGNO.: Mona Lisa SVG benchmark
Researcher observations

Clean contours, connected body forms and gentle gradients support a basic, coherent portrait. Likeness remains weak: the face dominates the body, the seated angle is lost, and crossed hands become dark lobes without traceable wrists or fingers. Readable facial details add some drawing complexity, but clothing, landscape and material treatment remain sparse.

Beach

Different task instructions

Hy4 Preview60.8/100

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.

Benchmark task

A busy shoreline at sunset tests scene composition, animal forms and the relationship between light and water reflections.

MISSINGNO.43.9/100

MISSINGNO.: Beach SVG benchmark
Researcher observations

A coherent sunset beach with clear requested subjects, balanced framing and clean shapes. The aligned solar reflection and warm gradients establish atmosphere. Primitive animal construction, ambiguous furniture, sparse depth cues and minimally developed surfaces limit its drawing complexity and physical richness.

Raccoon

Different task instructions

Hy4 Preview55.5/100

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.

Benchmark task

A jet-ski scene pairs a canine driver with a raccoon passenger. It tests the placement and contact of interacting subjects, along with vehicle construction.

MISSINGNO.57.5/100

MISSINGNO.: Raccoon SVG benchmark
Researcher observations

The requested interaction reads clearly through recognizable animals, expressive faces and a coherent hull-water relationship. Clean curves and readable accessories give the cartoon polish. Partly unresolved grips and supporting contacts limit physical construction; modest shape complexity, weak directional lighting and schematic water constrain its finish.

Pelican

Different task instructions

Hy4 Preview60.0/100

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.

Benchmark task

A cycling pelican tests anatomy, riding posture and contact between the bird and the bicycle.

MISSINGNO.58.8/100

MISSINGNO.: Pelican SVG benchmark
Researcher observations

A coherent, cheerful illustration with recognizable pelican features, balanced composition, clean contours and useful small details. Its controlled curves and layered wheels demonstrate competent drawing skill. Ambiguous pedal and steering contacts, sparse drivetrain construction and weak directional lighting limit the riding mechanics and finish.
