Gemma 4 26B A4B8.2/100

Gemma 4 26B A4B: Newton's Mirror SVG benchmark
Researcher observations

Separate airborne black and contact-compatible paint flattening earn partial state credit. Settlement, adhesion and differentiated paint transport remain unresolved. The enlarged, low sphere and thin lamp strip substantially depart from the required camera, while the defining mirror structure is missing. Weak material appearance and oversized black paint limit material credit. The retained base total is 18/170; the floor-damage reward is 0, giving 18/180.

Benchmark task

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.

Owl Alpha23.5/100

Owl Alpha: Newton's Mirror SVG benchmark
Researcher observations

Cyan lies on the sphere's facing middle rather than showing its recent interaction near the apex. Separate airborne black and elongated crimson support part of the timing sequence. Small side images and an overlapping lower image provide limited reflection ordering, but recursive room structure, nested imagery and emitter mappings are largely absent. The main sphere is smaller and higher in the frame than prescribed, and the surfaces have a soft, matte appearance.

Selfie

Different prompts

Gemma 4 26B A4B52.8/100

Gemma 4 26B A4B: Selfie SVG benchmark
Researcher observations

An appealing, readable sparkle-creature with luminous colour and expressive eyes. Simple geometric construction limits sophistication, while sharp body points, ambiguous hand contact and a minimally resolved jar weaken the requested soft, plump character and treasure-presenting pose.

Prompt withheld

Owl Alpha61.6/100

Owl Alpha: Selfie SVG benchmark
Researcher observations

Amber slit eyes, a pointed beak, cream feathers and gold-trimmed black clothing establish the secretive owl rogue. The head appears frontal rather than lowered, with much of the face exposed. The centered silhouette is effective, but stiff cloak geometry, shallow facial modeling and extremely dark clothing limit depth and finish. Sparse gold markings suggest the requested circuitry only loosely.

Benchmark task

Draw a secretive owl in a black hood and cloak. She lowers her head but looks up at the viewer with glowing golden eyes. Small glowing patterns in her clothing hint that she is an AI.

Mona Lisa

Different prompts

Gemma 4 26B A4B17.8/100

Gemma 4 26B A4B: Mona Lisa SVG benchmark
Researcher observations

The centered dark-haired portrait provides a loose reference cue, but its elongated, nearly featureless face and undifferentiated torso fall far short of replication. Crossed hands, the subtle smile, clothing structure and landscape are unresolved. Clean silhouettes and soft gradients provide limited coherence.

Benchmark task

Owl Alpha4.1/100

Owl Alpha: Mona Lisa SVG benchmark
Researcher observations

The centered portrait, slight smile, overlapping hands and distant landscape suggest Mona Lisa, but replication is weak. The face has little volume, the shoulders and torso form a narrow wedge, and the hands are fingerless ovals with unresolved wrists. Broad gray background bands provide limited depth. A bright head rim and pale hands contrast with an almost featureless dark figure.

Beach

Different prompts

Gemma 4 26B A4B28.5/100

Gemma 4 26B A4B: Beach SVG benchmark
Researcher observations

A clean, balanced sunset scene demonstrates the beach, birds and a centered reflection. Animals and play receive only minimal treatment. Coherent layers and controlled gradients support readability, but unresolved aquatic anatomy, sparse details and weak surface modeling keep the drawing basic.

Benchmark task

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

Owl Alpha53.6/100

Owl Alpha: Beach SVG benchmark
Researcher observations

The sunset, palms, birds and beach animals create a cheerful, readable scene. Clean silhouettes and a vivid sky establish the composition, but construction remains schematic. The right palm appears rooted in open water, shadows have limited connection to the sunset, and the sun’s reflection consists of rigid bands. Small creatures and beach equipment are recognizable but minimally developed.

A dark steel room has four pillars and two warm ceiling lights. A wooden plank is placed over a computer mouse, with a blueberry on the plank above it. Draw the scene a few seconds later, showing how the objects settle and how the light, shadows and surfaces look.

Raccoon

Different prompts

Gemma 4 26B A4B40.3/100

Gemma 4 26B A4B: Raccoon SVG benchmark
Researcher observations

The animal stack is recognizable, and clean silhouettes support a basic illustration. Steering is not depicted, while the craft's construction and water contact remain unresolved. Sparse anatomical and material detail limit the finish. The sky gradient and glow provide atmospheric lighting, but the subjects lack corresponding modeling.

Benchmark task

Owl Alpha45.3/100

Owl Alpha: Raccoon SVG benchmark
Researcher observations

The raccoon is recognizable and expressive, with a clear mask and striped tail. The dog's anatomy is poorly resolved, and the flattened craft lacks convincing steering and seating. Feet extend below the hull, weakening the sense of support. An appealing palette, clean shapes and decorative water effects give the illustration some polish.

Pelican

Different prompts

Gemma 4 26B A4B48.5/100

Gemma 4 26B A4B: Pelican SVG benchmark
Researcher observations

A clean, balanced icon suggests a pelican riding a bicycle. Continuous contours and restrained colors support its finish, but the abbreviated bill, undifferentiated body, unresolved riding contacts and incomplete bicycle mechanism limit likeness and construction. Sparse detail and flat lighting keep the drawing basic despite its clarity.

Benchmark task

Owl Alpha79.0/100

Owl Alpha: Pelican SVG benchmark
Researcher observations

A clearly recognizable pelican cycles through a well-composed coastal sunset. Warm colors, flowing scarf, feather contours and bicycle details give the illustration character. The legs connect to the body, but the farther foot's pedal contact and the wing's handlebar grip remain ambiguous. Clean vector shapes provide polish, with limited material texture and directional shading.
