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.

Mistral Large 4 030.2/100

Mistral Large 4 0: Newton's Mirror SVG benchmark
Researcher observations

The central sphere, airborne black and deformed crimson support substantial state and placement credit. Recent cyan contact and crimson transport remain uncertain. Sparse wall patches and glossy gradients provide little evidence of the required extensive mirror system, while the missing centerline lamp and bulky crimson remain visible weaknesses.

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.

Mistral Large 4 072.5/100

Mistral Large 4 0: Selfie SVG benchmark
Researcher observations

An appealing, coherent illustration whose enormous rounded cat anchors the windblown composition. Warm shading and floating sketches communicate the brief well. Simplified paws, faint ear construction, inconsistent wind cues and limited material texture keep the execution below exceptional.

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.

Exact prompt

Mistral Large 4 041.7/100

Mistral Large 4 0: Mona Lisa SVG benchmark
Researcher observations

A recognizable, cleanly rendered interpretation with a restrained palette and some facial modeling. Its enlarged frontal head, simplified expression, compressed low hands and schematic landscape substantially limit likeness and construction. The smooth rendering does not reproduce the painting's nuanced anatomy, clothing or atmospheric depth.

Beach

Different prompts

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.

Exact prompt

Mistral Large 4 065.4/100

Mistral Large 4 0: Beach SVG benchmark
Researcher observations

A clean, appealing beach illustration with clear subject coverage, a cohesive sunset palette and expressive animal details. Bodies and accessories resolve basic construction coherently, although joints remain schematic. Layered shapes establish modest depth; generic oval shadows and flat surfaces limit physical richness. Repeated forms and sparse articulation leave room for more accomplished drawing.

Raccoon

Different prompts

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.

Mistral Large 4 069.5/100

Mistral Large 4 0: Raccoon SVG benchmark
Researcher observations

The central interaction is clear, with recognizable animals, expressive faces and a coherent sunset composition. Clean contours and readable accessories give the cartoon polish. Simplified joints, uncertain steering attachment, shallow hull volume and limited directional lighting constrain its physical resolution.

Pelican

Benchmax control

Outside General and Visual Intelligence. Excluded from the overall score for GPT 6.1 Sol and Mistral Large 4 0.

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.

Mistral Large 4 072.3/100

Mistral Large 4 0: Pelican SVG benchmark
Researcher observations

A coherent, appealing pelican illustration with a continuous body silhouette, readable bicycle and grounded wheels. Simplified legs and ambiguous steering and pedal connections limit construction. Clean shapes and expressive accessories succeed, while shallow depth, modest lighting and sparse material differentiation leave substantial room for refinement.
