Geometric Composition

Text-to-Image

“A glass cube on a wooden table. Inside the cube is a small blue sphere. On top of the cube sits a red book. A green plant is behind the cube, partially visible through the glass. Soft window light from the left.”

AI Judge Analysis

OmniGen v2

  • + Excellent photographic clarity and lighting
  • + Highly accurate adherence to the glass cube and sphere placement
  • + Realistic window light reflection on the blue sphere
  • The plant in the background is not very visible through the glass due to the angle and glass thickness

Qwen Image 2512

  • + Strong textures on the wood table and book cover
  • + Features complex reflections within the glass structure
  • The 'glass cube' appears more like an open box or a series of mirrors rather than a solid transparent cube
  • The back wall of the cube is missing or misaligned with the plant background
  • The sphere appears to have a ghosted/extra reflection that confuses the geometry

Verdict: OmniGen v2 produced a much cleaner and more physically coherent image that perfectly followed the spatial instructions. While Qwen Image 2512 had nice textures, it failed to render the glass cube as a logical, three-dimensional object, resulting in confusing reflections and missing planes.

Candid Street Photography

Text-to-Image

“A candid street photo of an elderly Japanese man repairing a red bicycle in light rain, reflections on wet pavement, shallow depth of field, 50mm lens, natural skin texture, imperfect framing, motion blur from passing cars, cinematic but realistic, no stylization.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Excellent full-body reflection on the wet pavement.
  • + Clear rendering of rain droplets against the background.
  • The man appears to be standing with the bike rather than repairing it.
  • The image has a clean, digital look that lacks the requested motion blur and imperfect framing.

Qwen Image 2512

  • + Successfully captures the requested motion blur from passing cars.
  • + Follows the candid street photography aesthetic with realistic skin textures and imperfect framing.
  • + The subject is crouched down as if in the middle of a repair.
  • The bike's mechanical details, like the spokes and chain guard, are slightly warped.
  • The right hand resting on the seat has anatomical irregularities.

Verdict: Qwen Image 2512 is the clear winner for its superior adherence to the stylistic requirements, capturing the motion blur and 'candid' feel requested in the prompt. While OmniGen v2 produced a clean and high-quality image, it failed to incorporate the specific street photography elements like motion blur and realistic environmental imperfections.

Fantasy Warrior

Text-to-Image

“Close portrait of a battle-worn paladin in ornate engraved plate armor, hair braided with small beads, faint scars and dirt on the skin, warm torchlight reflecting off metal, shallow depth of field, bokeh sparks, lifelike eyes, highly detailed texture on leather straps and cloth underlayer.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Excellent depiction of ornate engraving on the plate armor
  • + Clean, aesthetically pleasing composition with vibrant warm lighting
  • + Accurate representation of the braided hair with beads
  • The character looks too clean and youthful, failing the 'battle-worn' descriptor
  • Skin texture is somewhat plasticky and lacks the requested grit and realistic scars
  • The 'dirt' looks like superficial makeup spots rather than grime

Qwen Image 2512

  • + Perfectly captures the 'battle-worn' aesthetic with realistic scars, dirt, and facial wearyness
  • + Incredible detail on the leather straps, buckles, and fabric underlayers
  • + Dynamic lighting and bokeh sparks create a much more immersive atmosphere
  • The braids are a bit messy and blend into the loose hair strands compared to the clean braids in A

Verdict: Qwen Image 2512 is the superior choice because it fully embraces the 'battle-worn' aspect of the prompt, delivering high-fidelity skin textures, realistic scars, and gritty details. While OmniGen v2 produces a beautiful image, it is far too polished and clean for a veteran paladin, missing the requested character depth and detailed leather/cloth textures present in Qwen's output.

Modern Clean Menu

Text-to-Image

“Modern minimalist restaurant menu design, white background with colorful food photos in grid, sections for appetizers/pizza/mains, bold sans-serif fonts, vibrant accents, clean professional layout for casual dining.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Excellent use of white space that reflects a modern minimalist aesthetic.
  • + Individual food photos are high quality and clearly presented.
  • + The two-page spread layout creates a professional hierarchy.
  • Numerous spelling errors in headings like 'APPTETIZES' and 'PIZZZZAN'.
  • The text blocks for menu items are completely illegible greeking/nonsense.

Qwen Image 2512

  • + Better execution of the 'grid' request for food photos.
  • + More functional menu layout with numeric prices and categorical icons.
  • + The fonts used are bold and modern, fitting the casual dining prompt.
  • Text rendering is heavily garbled and contains nonsensical characters.
  • Some food photos in the grid appear slightly repetitive or lack distinct clarity.

Verdict: OmniGen v2 excels in minimalist composition and general aesthetic, feeling more like a real designer's mockup in terms of spacing. However, Qwen Image 2512 offers a more practical interpretation of the prompt's request for a 'grid' and 'vibrant accents', provided one can overlook the garbled text characters. OmniGen v2 is the preferred visual winner for its cleaner, more sophisticated minimalist design.

Magic Burger Explosion: Fiery Photorealism Challenge

Text-to-Image

“Ad for 'Magic Burger'. Dynamic, exploded burger with all components (bun, patty, cheese, lettuce, tomato, sauce) suspended in mid-air. Emphasize photorealistic detail and a sense of motion. Dark, fiery background with glowing embers. Integrate text: 'MAGIC BURGER' as a prominent title, 'LIMITED TIME ONLY' as a secondary message, and '€6.99' in a starburst, all rendered with a fiery, glowing effect.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Clean typography and layout
  • + Vibrant, high-contrast colors
  • + Perfect spelling for most text elements
  • Failed to create an 'exploded' burger with suspended components
  • Missing the Euro symbol in the price
  • Looks more like a 2D graphic than a photorealistic advertisement

Qwen Image 2512

  • + Successfully rendered the 'exploded' burger with dynamic movement
  • + Highly detailed and photorealistic food textures
  • + Followed all text instructions including the Euro symbol and starburst
  • Minor text truncation ('LIMITED ONLY' instead of 'LIMITED TIME ONLY')
  • The background floor adds a bit of visual clutter compared to the clean prompt request

Verdict: Qwen Image 2512 followed the core structural instructions much better, delivering the requested 'exploded' view with high photorealism and a fiery aesthetic. While OmniGen v2 produced a cleaner graphic, it failed the primary compositional requirement of separating the burger components in mid-air.

Chalkboard Menu

Text-to-Image

“Handwritten-style chalkboard menu in a cozy café, all text rendered in the exact same realistic chalk handwriting style with natural variations in letter size, slight slant, and chalk texture — no printed or digital fonts anywhere on the board. Title at the top in elegant cursive chalk handwriting: ‘TODAY’S SPECIALS – APRIL 30, 2026’. Below it, three menu items also in the same handwritten chalk style: ‘Truffle Mushroom Risotto – $24’, ‘Grilled Octopus with Lemon & Herbs – $28’, ‘Brown Butter Chocolate Chip Cookies – $9’. At the very bottom, smaller text in the identical handwritten chalk style (slightly smaller but still clearly legible with the same handwriting characteristics): ‘All items made fresh daily • Ask about our gluten-free options’. Warm ambient café lighting, visible chalk dust and smudges, realistic handwriting imperfections, no clean printed text anywhere.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + The text has a strong chalk texture.
  • + Bold and clear font for the header.
  • Numerous spelling errors including 'SPECALS', 'Musonhom', and 'Lemont'.
  • Text layout is cluttered and contains extra random prices.
  • Failed to render elegant cursive as requested for the title.

Qwen Image 2512

  • + Excellent adherence to the 'elegant cursive' title and handwritten chalk style.
  • + Nearly perfect spelling across all requested menu items and dates.
  • + Great composition with a realistic café background and authentic chalk smudges.
  • Minor spelling error in 'Risitto' (missing an 'o').
  • Slightly less 'chalky' edge texture compared to Model A.

Verdict: Qwen Image 2512 is the clear winner as it successfully rendered the elegant cursive title and all requested menu items with high accuracy and beautiful composition. OmniGen v2 struggled significantly with text coherence, producing gibberish words and a messy layout that failed to follow the item list provided in the prompt.

The Reversed Rodeo

Text-to-Image

“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Clean, vibrant colors with a clear 'surreal' aesthetic.
  • + Good composition with a balanced background involving multiple moons.
  • + High clarity in the rendering of the astronaut suit.
  • Completely failed the negative constraint; it shows an astronaut riding a horse instead of a horse riding an astronaut.
  • The horse's legs are cut off at the bottom of the frame.
  • The style is somewhat cartoony rather than cinematic.

Qwen Image 2512

  • + Very high detail in the astronaut suit and horse's fur.
  • + Cinematic lighting and realistic textures.
  • + Dynamic pose for the horse creates a sense of movement.
  • Failed the negative constraint; it shows an astronaut riding a horse.
  • The anatomy where the horse's back meets the astronaut's leg is slightly merged.
  • The background transition between the atmosphere and space is a bit abrupt.

Verdict: Both models failed the specific prompt instruction to place the horse on top of the astronaut, instead providing the common 'astronaut riding a horse' trope. Qwen Image 2512 is the superior image due to its significantly higher level of detail, better lighting, and more cinematic composition compared to the flatter, more illustrated look of OmniGen v2.

The Capybara Taxi Driver

Text-to-Image

“Photorealistic scene inside a yellow New York taxi at night. A capybara is driving, wearing a yellow taxi driver cap and a dark jacket. It has a calm, professional expression and both front paws on the steering wheel. In the back seat sits a human businesswoman in a coat, looking at her phone with a completely normal, bored expression (as if this is just another normal ride). Through the windows you can see the streets of Manhattan at night with blurred lights. Realistic taxi interior, photorealistic, detailed fur and fabric, 35mm lens, night lighting with reflections, shallow depth of field.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + The capybara's fur texture is rendered with high detail.
  • + The lighting on the interior and exterior is vibrant and aesthetically pleasing.
  • Major anatomical failure: the capybara has human hands instead of paws.
  • The human woman is sitting in the front passenger seat instead of the back seat as requested.

Qwen Image 2512

  • + Successfully positions the woman in the back seat and the capybara in the driver seat.
  • + Includes animal-like paws on the steering wheel as requested.
  • + The 'bored' expression on the passenger is accurately depicted.
  • The paws look slightly unnatural, appearing more like primate hands than capybara feet.
  • The composition is a bit tight, losing some of the 'New York' background detail.

Verdict: Qwen Image 2512 is the clear winner because it followed the spatial instructions and character details, whereas OmniGen v2 failed significantly by giving the capybara human hands and placing the passenger in the front seat. Qwen Image 2512 also captured the specific 'bored' nuance of the prompt much more effectively.

The Halloween Invitation

Text-to-Image

“Vintage gothic Halloween party invitation. Dark parchment poster, spooky border with webs and thorns, central glowing jack-o-lantern, bats, twisted trees, moody night sky. Add elegant gothic title text saying "Halloween Party Invitation", a small scroll banner saying "You are invited to a night of frights", and event details at the bottom: Date: 30.10.2026 Time: 7pm Location: The Arches, NYC Spooky but polished, cinematic lighting, square format.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Successfully rendered most of the requested text elements.
  • + Good use of color and high-contrast lighting for the jack-o-lantern.
  • + Includes the parchment texture and scroll element requested.
  • Text rendering contains several typos and hallucinations like 'The Arcas' and 'Friets'.
  • The art style is a bit more like a flat vector graphic than a cinematic vintage poster.
  • Layout is slightly cluttered with redundant text at the bottom.

Qwen Image 2512

  • + Higher visual quality with cinematic lighting and intricate details in the trees and border.
  • + Superior text legibility and accuracy, perfectly matching the location details.
  • + Excellent execution of the requested thorn and web border.
  • Minor spelling error in the word 'Hallowern' in the title.
  • The 'arch' of the scroll banner is a bit uneven.

Verdict: Qwen Image 2512 is the superior choice because it captures the 'cinematic' and 'vintage' aesthetic much More effectively than OmniGen v2. While Qwen has a small typo in the title, its overall composition, detailed textures, and perfect rendering of the event details make it a more professional-looking invitation.

Isometric Miniature Diorama Scenes

Text-to-Image

“Create a clear, 45° top-down isometric miniature 3D cartoon scene of Japan's signature dish: sushi, with soft refined textures, realistic PBR materials, gentle lighting, on a small raised diorama base with minimal garnish and plate. Solid light blue background. At top-center: 'JAPAN' in large bold text, 'SUSHI' below it, small flag icon. Perfectly centered, ultra-clean, high-clarity, square format.”

100% wins 0% ties 0% wins

AI Judge Analysis

OmniGen v2

  • + Excellent 3D isometric perspective and clean lighting
  • + Text is sharp, bold, and perfectly positioned
  • + Vibrant, appealing stylized colors
  • The flag icon is incorrect (red and yellow instead of Japanese flag)
  • The sushi anatomy is slightly nonsensical with a shrimp tail attached to a maki-like roll

Qwen Image 2512

  • + Includes a correct Japanese flag icon
  • + Higher variety of sushi types and more detailed textures on the ginger and wasabi
  • + Excellent adherence to the 'diorama' request with ground texture and small plants
  • The text is less bold and has a somewhat muddy drop shadow
  • Composition feels slightly more cluttered and less 'minimal' than requested

Verdict: Qwen Image 2512 is the winner as it accurately rendered the Japanese flag and provided a more detailed diorama that captured the miniature aesthetic better. While OmniGen v2 had cleaner typography, it failed on the specific cultural icon and produced nonsensical sushi shapes.

Adorable Baby Animals in Sunny Meadow

Text-to-Image

“Hyper-photorealistic scene of fluffy baby animals—a golden retriever puppy, tabby kitten, baby bunny, and red fox kit—with big expressive eyes and ultra-detailed soft fur, playfully chasing butterflies and tumbling together in a lush wildflower meadow, warm golden sunrise light with god rays and dew sparkles, joyful wholesome vibe, 8K masterpiece.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Successfully captures the requested golden sunrise lighting and god rays.
  • + Vibrant colors and a high-key, cheerful aesthetic.
  • Failed to include the baby bunny, showing only three animals.
  • The style is very illustrative or cartoonish, failing the 'hyper-photorealistic' part of the prompt.
  • Anatomical issues, particularly the fox's tail which looks like a white cotton ball.

Qwen Image 2512

  • + Successfully included all four requested animals (dog, cat, bunny, and fox).
  • + Achieved a much higher level of photorealism with detailed fur textures and realistic anatomy.
  • + Excellent composition that makes the animals look like they are tumbling or huddled together.
  • The butterflies appear somewhat static rather than being 'chased'.
  • The transitions between some animals' fur where they overlap are slightly blurred.

Verdict: Qwen Image 2512 followed the complex prompt much more accurately by including all four specified animals, whereas OmniGen v2 missed the bunny entirely. Furthermore, Qwen Image 2512 delivered a truly photorealistic image with fine fur detail, while OmniGen v2 produced a stylized, cartoon-like illustration.

Vintage Cafe Logo

Text-to-Image

“Vintage minimalist restaurant logo for "Caffè Florian", retro cloche dome with steam and "Est. 1720" banner, classic typography, warm brown and cream tones, subtle texture on light background, vector emblem style.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Strong vector emblem style
  • + Clean and minimalist composition
  • + Accurate depiction of a minimalist cloche dome
  • Misspelled the name as 'CAFFFLORIN'
  • Text rendering is slightly cramped on the banner

Qwen Image 2512

  • + Excellent text rendering with correct spelling and accent
  • + High artistic quality with detailed vintage woodcut-style shading
  • + Dynamic and visually appealing steam effects
  • Less minimalist than requested in the prompt
  • The banner at the bottom is slightly off-center compared to the text above it

Verdict: Qwen Image 2512 is the clear winner because it correctly spelled the requested restaurant name 'Caffè Florian' including the accent mark, whereas OmniGen v2 produced a typographical error. Although Qwen Image 2512 is more detailed and less 'minimalist' than the prompt specified, its superior visual quality and typography make it a much better logo.

Apollo 11: Journey to Tranquility

Text-to-Image

“Create a clean, modern vector infographic poster about the Apollo 11 mission. NASA-inspired palette (navy, white, muted red, light gray). Flat-vector style, crisp lines, consistent iconography, subtle gradients only. Steps (stop at landing): 1. Launch (Saturn Vicon) 2. Earth Orbit (Earth + orbit ring icon) 3. Translunar (trajectory arc icon) 4. Lunar Orbit (Moon + orbit ring icon) 5. Descent (lunar module descending icon) 6. Landing (lunar module on the surface icon) Small supporting elements (minimal text): • Crew strip: three silhouette icons with only last names: Armstrong, Aldrin, Collins. • Landing site marker: Moon pin labeled "Tranquility" only. Layout constraints: generous margins, large readable labels, clean background with subtle stars. Vector-only, print-poster look, high resolution.”

OmniGen v2
Qwen Image 2512

AI Judge Analysis

OmniGen v2

  • + Strong adherence to the requested color palette
  • + Clean, minimalist vector aesthetic with consistent icons
  • Confuses the mission number, labeling it Apollo 17 instead of 11
  • Extremely poor text rendering with many gibberish strings
  • Icons do not clearly correspond to the specific steps requested in the prompt

Qwen Image 2512

  • + Successfully includes all specifically requested steps and icons
  • + Features much more legible text, including names of the astronauts
  • + Higher level of detail in the rocket and lunar module illustrations
  • Includes odd text artifacts like 'Steps stop at landing' directly in the graphic
  • Duplicate numbering for steps (two step 2s, two step 3s) and inconsistent ordering
  • Uses an orange color that was not part of the requested muted NASA palette

Verdict: Qwen Image 2512 is the superior choice because it actually attempts to follow the structured steps of the infographic, providing recognizable icons for the Saturn V and Lunar Module as requested. While OmniGen v2 has a cleaner aesthetic, it fails on mission accuracy (citing Apollo 17 and 'NSA') and lacks the semantic connection between the icons and the mission stages.
