Kimi K336.6/100

Kimi K3: Newton's Mirror SVG benchmark
Researcher observations

The room fills the complete portrait frame without visible borders or labels. The main sphere and airborne black are convincingly placed within the portrait frame. Paint ordering is supported, but its contact and transport history remains weakly expressed. Symmetric wall ghosts, inverted floor imagery and panel echoes establish a basic mirror system. Diffuse gradients dominate, with little ordered nested imagery or repeated emitter mapping on either planar or spherical surfaces. The wall images sit too low, and the floor image is unusually large and low.

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

Kimi K378.8/100

Kimi K3: Selfie SVG benchmark
Researcher observations

The indigo creature and warm reflected counterpart create a balanced, contemplative composition. Equations, constellations and book emblems give the transformation meaning. Clean silhouettes and controlled glow support the scene, but minimally articulated legs, shallow spatial cues and smooth, generalized surfaces limit its anatomical and material richness.

Benchmark task

An imagined creature encounters its reflection. The scene tests original character design, visual self-interpretation and the relationship between a subject and its reflected image.

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

Kimi K342.4/100

Kimi K3: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, dark veil, folded hands and misty landscape clearly evoke Mona Lisa. Replication is limited by the elongated neck, simplified facial proportions and oval hands with shallow finger marks. Soft shading gives some volume, but pervasive blur substitutes for controlled painterly transitions and precise detail.

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

Kimi K375.6/100

Kimi K3: Beach SVG benchmark
Researcher observations

A coordinated sunset palette, expressive silhouettes and varied small details create a lively, appealing beach illustration. The central sun and framing palm and umbrella organize the busy scene, with clean contours preserving readability. Bodies and people remain diagrammatic, depth is shallow, and inverted figure reflections cross matte-looking sand without convincing surface lighting. Materials and movement are mostly conveyed through flat shapes.

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

Kimi K372.5/100

Kimi K3: Raccoon SVG benchmark
Researcher observations

The raccoon rides on the dog's back, and the dog's paw meets a steering assembly connected to the red hull. Expressive faces, a warm sunset and sweeping spray create an appealing composition. Crowded body overlaps obscure some limb connections, and the raccoon's right ear appears slightly separated. Flat shading and stylized reflections limit volume and depth.

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

Kimi K373.5/100

Kimi K3: Pelican SVG benchmark
Researcher observations

The pelican and bicycle are immediately recognizable, with an expressive bill, flowing scarf and cheerful composition. Both legs remain attached, but pedal connections and wing contact with the handlebar are weakly resolved. Wheel alignment and landscape layers are coherent. Clean outlines support the illustration, while flat surfaces and limited lighting keep it short of masterful execution.

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.
