Claude Haiku 5.5: Newton's Mirror SVG benchmark
Researcher observations

The centered sphere, compact airborne black blob and differentiated cyan/crimson interaction support substantial state and placement credit. The few recognizable sphere and panel images establish limited optical relationships, but most of the required mirror system is missing. Rounded volume and localized paint warrant substantial material credit despite the soft, illustrative finish.

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.

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.

Simplified prompt

Selfie

Different prompts

Claude Haiku 5.546.4/100

Claude Haiku 5.5: Selfie SVG benchmark
Researcher observations

A coherent coral squid emblem with a compact mantle, restrained face and clean centered presentation. Its radial silhouette and floating placement work, but sharp arm tips, crowded roots and sparse surface modeling limit softness, construction and finish.

Simplified prompt

Draw a calm coral-red squid with eight thick arms spreading around it like flower petals. Keep the shape balanced and simple, with soft shading and a friendly face.

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.

Simplified prompt

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

Claude Haiku 5.538.6/100

Claude Haiku 5.5: Mona Lisa SVG benchmark
Researcher observations

A recognizable but basic Mona Lisa reinterpretation. Clean contours and smooth facial lighting provide coherence and volume. Replication remains limited by the frontal pose, elongated neck, schematic expression, unresolved crossed hands and sparse landscape. Lighting is more successful than anatomical construction and purposeful detail.

Exact prompt

Replicate mona-lisa as SVG Make it a masterpiece, no tools allowed

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

Claude Haiku 5.571.9/100

Claude Haiku 5.5: Beach SVG benchmark
Researcher observations

A cheerful, coherent beach illustration with attractive sunset colors, readable accessories and clean silhouettes. Its sun and sailboat reflections establish useful physical relationships. Simple animal construction, flattened foreground placement, sparse directional shadows and minimally differentiated surfaces limit its drawing refinement.

Exact prompt

Create an SVG of a amazing beach scene. Sunset, animals, fun, birds, reflections Make it a masterpiece, no tools allowed

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.

Raccoon

Different prompts

Claude Haiku 5.547.3/100

Claude Haiku 5.5: Raccoon SVG benchmark
Researcher observations

A tidy, appealing cartoon with recognizable animals and a pleasing sunset palette. Steering lacks visible controls, while schematic limbs and uncertain raccoon support weaken the requested interaction. Shallow vehicle construction, flat character lighting and modest displacement limit physical coherence. Clean shapes and readable identifying details remain strengths.

Exact prompt

Generate an SVG: A raccoon sits on a dog's back while the dog steers a jet ski Make it a masterpiece, no tools allowed

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

Benchmax control

Outside General and Visual Intelligence. Excluded from the overall score for Claude Haiku 5.5 and Owl Alpha.

Claude Haiku 5.564.0/100

Claude Haiku 5.5: Pelican SVG benchmark
Researcher observations

A cheerful, recognizable illustration with clean contours and a balanced warm palette. Aligned wheels and readable frame geometry establish the bicycle, but shoulder construction, feet and steering contact remain imprecise. Sparse drivetrain detail, flat materials and absent grounding shadows limit anatomical and spatial conviction.

Exact prompt

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.
