GPT 6.1 Sol50.5/100

GPT 6.1 Sol: Newton's Mirror SVG benchmark
Researcher observations

Recognizable first sphere images and several central planar lights provide limited geometric agreement. Missing outer chains, truncated panel sequences and simplified interiors across the main, side and floor spheres leave most of the recursive reflection structure unsupported.

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.

Qwen3.6 35B A3B: Newton's Mirror SVG benchmark
Researcher observations

The artwork demonstrates rounded volume, recognizable paint colors and a compact black feature at an appropriate screen height. The enlarged main-sphere framing, unsupported crimson and cyan interaction histories, oversized compact paint balls and largely missing mirror structure remain substantial weaknesses. The core assessment is 20/170; with no demonstrated floor damage, the combined assessment remains 20/180.

Selfie

Different prompts

GPT 6.1 Sol76.0/100

GPT 6.1 Sol: Selfie SVG benchmark
Researcher observations

Six outward-facing heads and evenly arranged loops make the pale interlocking knot immediately readable. Uniform widths, angular inner bends and fine scales preserve its ornamental geometry. The bodies feel more like textured tubes than living muscle: shading is subdued, crossing contact shadows are weak, and visible curved seams interrupt surface continuity. Small heads have readable eyes and jaws but limited anatomical depth.

Simplified prompt

Draw a pale six-headed snake woven into a symmetrical knot. Its body passes over and under itself around a small hexagonal opening, with six little heads facing outward. Add lifelike scales, curved muscles and shadows without losing the clear knot shape.

Qwen3.6 35B A3B66.4/100

Qwen3.6 35B A3B: Selfie SVG benchmark
Researcher observations

An appealing fantasy illustration with coordinated ornament, readable suspension and luminous turquoise accents. Plausible limb attachments and soft shading support competent execution. Bear-like proportions, unclear paw gestures, insufficient white robe fabric, crowded chest details and shallow material modeling limit its finish.

Simplified prompt

Draw a friendly capybara floating in ornate green and white robes. A glowing halo and small floating orbs surround it, giving it the feel of a gentle fantasy guide.

Mona Lisa

Different prompts

GPT 6.1 Sol61.4/100

GPT 6.1 Sol: Mona Lisa SVG benchmark
Researcher observations

The recognizable pose, dark clothing and misty landscape form a coherent portrait. Soft facial shading creates volume, but the broad face, outlined eyes and simplified smile limit likeness. Overlapping hands have flattened fingers and ambiguous separation. Angular landscape shapes and sparse fabric detail keep the execution competent rather than masterful.

Qwen3.6 35B A3B: Mona Lisa SVG benchmark
Researcher observations

A recognizable but basic geometric interpretation. Muted colors and soft shading provide cohesion, while weak likeness, unresolved hands, rigid anatomy and shallow landscape construction substantially limit the replication.

Beach

Same prompt

GPT 6.1 Sol76.3/100

GPT 6.1 Sol: Beach SVG benchmark
Researcher observations

A cohesive sunset palette, sweeping shoreline and framing palm create an appealing beach illustration. Animals, birds, play and a prominent sun reflection fulfill the brief. Connected but schematic figures and simplified dolphin anatomy limit construction; stepped reflections and mostly flat surfaces limit lighting and material depth. Small beach accessories remain readable and edges are clean.

Researcher observations

A recognizable beach sunset with balanced framing and appealing color transitions. Birds, boats and small animals fulfill the main scene requirements. Elementary anatomy, faint details, weak grounding and rigid reflection columns limit depth and finish.

Raccoon

Same prompt

GPT 6.1 Sol78.3/100

GPT 6.1 Sol: Raccoon SVG benchmark
Researcher observations

The masked raccoon rides the dog's back, and the dog's forepaw meets a handlebar connected to the deck. Expressive faces, a striped tail and sweeping wake create an appealing composition. Overlapping bodies compress the seating and rear-leg anatomy; hull depth and sunset illumination remain schematic.

Qwen3.6 35B A3B51.9/100

Qwen3.6 35B A3B: Raccoon SVG benchmark
Researcher observations

Clean shapes, cheerful faces and bright colors make the riding arrangement readable. The dog does not visibly operate the control, while awkward limbs, shallow hull placement and stiff poses limit credibility. Gradients and layered foam add modest volume and motion. The obscured tail attachment does not establish detachment.

Pelican

Outside General and Visual Intelligence. Excluded from the overall score for GPT 6.1 Sol and Qwen3.6 35B A3B.

GPT 6.1 Sol79.0/100

GPT 6.1 Sol: Pelican SVG benchmark
Researcher observations

A clearly recognizable pelican rides a well-composed bicycle through a warm coastal scene. The expressive bill, restrained palette and carefully drawn wheels give the illustration character. Leg-to-pedal connections are less convincing, especially the obscured far foot. Lighting provides gentle volume but little directional shadow. The small subtitle is clipped at the lower border.

Qwen3.6 35B A3B61.5/100

Qwen3.6 35B A3B: Pelican SVG benchmark
Researcher observations

A cheerful, readable illustration with a distinctive pelican silhouette, clean contours and an orderly landscape. Soft glow and restrained shading provide modest atmosphere. Construction is weaker: the handlebar is disconnected, wings do not reach the controls, and overlapping legs leave pedaling ambiguous. Simple forms and mostly flat materials limit depth and drawing sophistication.
