Claude Haiku 5.540.0/100

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.

The exact prompt is held back to prevent benchmaxxing.

Mimo V2.6 Flash9.2/100

Mimo V2.6 Flash: Newton's Mirror SVG benchmark
Researcher observations

The faint lower sphere image provides limited reflection evidence through reversed paint-color ordering. The wider reflection system and nested room imagery are absent. The colored beads do not resolve the required impact and transport history, while displaced paint positions and weak material rendering further limit the result.

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.

Mimo V2.6 Flash74.1/100

Mimo V2.6 Flash: Selfie SVG benchmark
Researcher observations

The centered rabbit has an appealing alert expression, a balanced silhouette, and a restrained technological palette. Outfit panels and orbital accents are cleanly resolved. The orb-holding paw has an ambiguous grip, the ears lack distinct angular bends, and the halo's interlocking construction is unclear. Soft shading suggests volume, but materials and spatial depth remain simplified.

Simplified prompt

Draw a small white rabbit in a futuristic explorer outfit. It floats upright, reaching out with one paw and holding a glowing orb with the other. Geometric rings behind it suggest a connected, technological world.

Mona Lisa

Same prompt

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

Mimo V2.6 Flash32.5/100

Mimo V2.6 Flash: Mona Lisa SVG benchmark
Researcher observations

The dark clothing, long hair, folded hands and hazy landscape make the reference recognizable. Replication is limited by the frontal symmetry, elongated face, wide staring eyes and downturned mouth. Both arms connect to the hands, but the overlapping palms and looplike fingers are poorly resolved. Soft facial shading provides some volume; the clothing and landscape remain broad, simplified shapes.

Beach

Same prompt

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

Mimo V2.6 Flash67.0/100

Mimo V2.6 Flash: Beach SVG benchmark
Researcher observations

The warm sunset, aligned reflection, framing palms and playful beach animals create an appealing, coherent scene. Small toys and shells remain readable. Drawing is simplified: animals have limited volume, water uses repetitive horizontal strokes, and foreground shadows do not consistently follow the central sun. Clean execution supports a competent illustration, but depth and material rendering remain modest.

Simplified prompt

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

Same prompt

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

Mimo V2.6 Flash51.3/100

Mimo V2.6 Flash: Raccoon SVG benchmark
Researcher observations

The raccoon riding the dog reads clearly, with expressive faces and a cheerful waterscape. The steering action is weak: no paw reaches the handlebar, which meets the dog's muzzle. The vehicle resembles a thin board with a steering post. Overlapping limbs obscure anatomy, while limited shadows, reflections and surface modeling keep the scene flat.

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for Claude Haiku 5.5 and Mimo V2.6 Flash.

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

Mimo V2.6 Flash66.3/100

Mimo V2.6 Flash: Pelican SVG benchmark
Researcher observations

The pelican is immediately recognizable, with an expressive eye and prominent pouch, and the landscape provides clear framing. Clean outlines and spokes support the cheerful illustration. Both feet visibly miss the bicycle's pedal mechanism, weakening the riding action. Simplified machinery, shallow depth and loosely directional shading limit the requested masterpiece quality.
