GPT-6 Astra57.8/100

GPT-6 Astra: Newton's Mirror SVG benchmark
Researcher observations

Major placement and the visible contact sequence are convincing. Dense planar light repetition, recognizable spherical panel images and simplified nested sphere motifs provide useful optical structure. Missing outer chains, truncated distant sequences and incorrect bead-like belts still leave the recursive reflections substantially incomplete.

Mimo V2.6 Flash7.8/100

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.

Selfie

Different prompts

GPT-6 Astra76.0/100

GPT-6 Astra: Selfie SVG benchmark
Researcher observations

The sixfold silhouette, pale coloring, outward heads and central hexagon closely match the brief. Fine scales and soft shading support rounded volume. However, several crossings have conspicuous rectangular seams and weak contact shadows, making the weave feel assembled. Small heads have limited anatomical definition, and the repetitive texture conveys less organic life than requested.

Mimo V2.6 Flash76.8/100

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.

Beach

Same prompt

GPT-6 Astra76.8/100

GPT-6 Astra: Beach SVG benchmark
Researcher observations

A coherent sunset beach illustration with an inviting palette, strong palm framing and a clear sun reflection. Animals, playing figures and beach equipment provide variety. Simplified human and dog anatomy, weak dolphin splash cues and uneven shadow directions limit physical conviction. Clean silhouettes and small decorative details support an appealing, polished composition.

Mimo V2.6 Flash73.8/100

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.

Mona Lisa

Different prompts

GPT-6 Astra67.3/100

GPT-6 Astra: Mona Lisa SVG benchmark
Researcher observations

The crossed hands, restrained smile, dark clothing and hazy landscape clearly recall the Mona Lisa. Replication is limited by the frontal, elongated face, schematic eyes and stiff fingers. Soft shading gives basic volume, but broad garment shapes and angular scenery lack the original’s nuanced depth and painterly transitions. The frame and composition are controlled; surface grain adds texture without resolving the simplified drawing.

Mimo V2.6 Flash47.5/100

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.

Raccoon

Same prompt

GPT-6 Astra79.5/100

GPT-6 Astra: Raccoon SVG benchmark
Researcher observations

Expressive animals, a balanced sunset composition and sweeping wake make an appealing illustration. The raccoon rides the dog's back, and the dog's connected foreleg reaches the controls. The compact steering assembly and layered paws are less clearly constructed. Lighting remains mostly flat, with little shadow or sun reflection. Clean contours and purposeful details support strong illustrative execution.

Mimo V2.6 Flash58.8/100

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.

GPT-6 Astra75.8/100

GPT-6 Astra: Pelican SVG benchmark
Researcher observations

The pelican's long bill, flowing scarf and warm coastal palette create a charming, balanced illustration. Wheels, spokes and frame are largely coherent, but neither wing reaches the handlebars, and the rear leg's pedal contact is unclear. Flat lighting and simplified surfaces limit depth despite clean outlines and attractive feather detail.

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.
