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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent photographic quality with realistic textures and lighting.
- + Convincing glass reflections and caustics on the sphere and table.
- + The plant is realistically blurred and visible through the glass as requested.
- − The sphere is a bit dark, bordering on black rather than a vibrant blue.
OmniGen v2
- + Perfect adherence to all colors, specifically the bright blue sphere.
- + Clear composition that follows the spatial instructions of the prompt.
- + Good lighting coming from the window on the left.
- − The sphere appears to be floating rather than sitting on the bottom of the cube.
- − The perspective of the cube's interior floor is slightly inconsistent with its outer edges.
- − The plant is not visible through the glass cube, only behind it.
Verdict: FLUX.1 Krea [dev] produces a much more realistic and aesthetically pleasing image with sophisticated light handling, whereas OmniGen v2 provides better color accuracy for the blue sphere but fails to show the plant through the glass. FLUX.1 Krea [dev] is preferred for its superior texture, realistic reflections, and overall photographic fidelity.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent depiction of motion blur on passing cars as requested.
- + Captures a gritty, 'imperfect' street photography aesthetic.
- + Realistic skin texture and natural lighting.
- − The man is pushing or holding the bike rather than actively 'repairing' it.
- − The bicycle's structure has some minor logical inconsistencies around the handle bars.
OmniGen v2
- + Clean, vibrant colors with strong reflections on the pavement.
- + Clear focus on the subject with a pleasant shallow depth of field.
- + Good character design and posture.
- − Failed to include motion blur on the background cars as requested.
- − The image feels overly clean and 'AI-perfect,' missing the requested 'imperfect framing' and 'no stylization'.
- − The bike's pedal is floating and not connected to a crank arm.
Verdict: FLUX.1 Krea [dev] followed the technical camera prompts much better, successfully incorporating motion blur and an 'imperfect' street photography feel that looks cinematic yet realistic. OmniGen v2 produced a higher-contrast, cleaner image that ignored specific prompt instructions regarding motion blur and framing, resulting in a more generic AI look with significant anatomical errors in the bicycle's construction.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent depiction of ornate, battle-worn armor with realistic grime and texture.
- + Cinematic lighting with convincing bokeh sparks and warm reflections.
- + Strong facial detail and a stoic expression that fits the 'battle-worn' theme.
- − The braids are very subtle and located at the hairline, rather than being a prominent feature of the hairstyle.
OmniGen v2
- + Clear representation of the braided hair with beads as requested.
- + Good lighting contrast between the torchlight and the subject.
- + Clean, lifelike eye rendering.
- − The armor looks somewhat plastic and lacks the complex 'battle-worn' texture and engravings of the competitor.
- − The character looks too pristine and youthful for a 'battle-worn' warrior, despite the superficial dirt marks.
- − The leather and cloth textures are less detailed.
Verdict: FLUX.1 Krea [dev] is the superior model for this prompt as it captures the gritty, 'battle-worn' aesthetic with much higher fidelity in the armor engravings and skin textures. While OmniGen v2 followed the hair braiding instructions more literally, the overall material quality and cinematic atmosphere of FLUX.1 Krea [dev] make it a more convincing interpretation of the scene.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Features a highly realistic and professional layout similar to modern food delivery apps.
- + The food photography grid is well-integrated and visually appetizing.
- + The typography is clean and mimics real menu prices and descriptions effectively.
- − Contains duplicate section headers for 'Appetizers'.
- − Text contains minor gibberish spelling like 'DESIORN'.
OmniGen v2
- + Good use of vibrant color accents and geometric blocks behind the food photos.
- + More creative interpretation of a foldable menu layout.
- + Clearer distinction between different menu categories.
- − Spelling is poor with significant errors like 'PIZZZZAN' and 'RESTAURATED MENTS'.
- − The text blocks for descriptions are just illegible scribbles.
- − The layout feels less like a professional menu and more like an unfinished template.
Verdict: FLUX.1 Krea [dev] is the winner because it provides a much more professional and coherent layout that genuinely looks like a restaurant menu, including realistic price formatting and high-quality food photography. While OmniGen v2 attempts a creative layout with vibrant accents, it is held back by severe spelling errors and illegible text blocks that detract from the professional aesthetic.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent photorealistic texture on the bun and meat.
- + Accurately represents the 'exploded' burger request with separated components.
- + Highly successful implementation of the dark, fiery background with glowing embers.
- − Failed to place the price '€6.99' inside a starburst.
- − Text rendering include some minor artifacts and unnecessary secondary logos in the corners.
OmniGen v2
- + Bold, clean typography for the primary title.
- + Accurately placed the price within a starburst as requested.
- + Vibrant colors and high-contrast composition.
- − Completely ignored the request for an 'exploded burger' with suspended components.
- − Lacks the photorealistic detail requested, appearing more like a digital illustration.
- − Missing the Euro symbol (€) in the price.
Verdict: FLUX.1 Krea (dev) followed the complex structural instructions much better, delivering a truly exploded burger with high-end photorealistic textures. While OmniGen v2 achieved the starburst element and bold text, it failed to deliver the core 'exploded' concept or the requested realism, resulting in a static and overly-illustrated image.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent text legibility and mostly accurate spelling.
- + Beautiful chalk texture with authentic smudge marks on the board.
- + Clean and elegant composition that maintains the cozy café aesthetic.
- − Includes several hallucinations and repetitious lines not in the prompt.
- − The 'Grilled Octopus' line contains gibberish ('with tceman').
OmniGen v2
- + Captured the cursive/printed mix requested in the prompt more distinctly.
- + Followed the date formatting and specific pricing more closely.
- − Significant spelling errors throughout ('Specals', 'Musonhom', 'Lemont').
- − The handwriting is messy and cluttered, overlapping in several places.
- − Lack of chalk texture makes the text look more like a digital brush than physical chalk.
Verdict: FLUX.1 Krea [dev] is the clear winner despite adding extra menu items, as its text is legible and the visual rendering of a physical chalkboard is highly realistic. OmniGen v2 struggled significantly with spelling, layout, and providing a convincing chalk texture, resulting in a cluttered and difficult-to-read image.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Features a high-quality, cinematic art style with lighting that matches the orbital backdrop.
- + Includes interesting details like mechanical armor/harness for the horse.
- − Fails to follow the specific prompt instruction to have the horse on top of the astronaut.
OmniGen v2
- + Clean, illustrative style with nice color contrast.
- + Clear rendering of astronaut equipment and horse tack.
- − Completely ignores the specific prompt logic 'horse on top, not vice versa'.
- − The anatomy of the horse legs at the bottom is noticeably distorted.
Verdict: Both models failed the specific spatial reasoning challenge of placing the horse on top of the astronaut. FLUX.1 Krea (dev) is the likely winner because it provides a much more realistic, cinematic image compared to the sticker-like quality of OmniGen v2, which also suffered from minor anatomical artifacts.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent adherence to the capybara's anatomy being used for paws on the wheel
- + Accurately places the businesswoman in the back seat as requested
- + Better interior lighting and realistic taxi signage
- − Includes an extra passenger in the front seat that wasn't requested
OmniGen v2
- + High clarity on the capybara's facial texture
- + Good blurring of the city background
- − Failed to render paws, giving the capybara human hands instead
- − Placed the businesswoman in the front seat instead of the back seat
- − Anatomically disconnected neck and head for the capybara
Verdict: FLUX.1 Krea [dev] followed the complex spatial instructions much better, placing the businesswoman in the back seat and providing the capybara with appropriate animal paws. OmniGen v2 struggled with the prompt, giving the animal driver human hands and failing to understand the passenger's seating position.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent atmospheric lighting and vintage gothic aesthetic.
- + Ornate border with highly detailed spider webs and thorns.
- + Superior illustration quality and composition.
- − Significant text hallucinations including 'Pasty Halloween' and 'You are are invited'.
- − Small scroll text is cluttered and difficult to read.
OmniGen v2
- + Accurately rendered the primary 'Halloween Party Invitation' title text.
- + Includes all requested event details like the date and location in a legible format.
- + Good use of backlight to create a 'moody night sky' effect.
- − Several spelling errors in the smaller text fields (e.g., 'Of Friets', 'The Arcas').
- − Graphic design style feels more modern/vectorized rather than 'vintage gothic'.
- − Jack-o-lantern is a flat silhouette rather than a detailed glowing character.
Verdict: FLUX.1 Krea (dev) produces a much more beautiful and atmospheric image with intricate gothic details, but it fails significantly on text legibility and accuracy. OmniGen v2 captures the requested layout and prints almost all the specific text details successfully, though its artistic style is less polished and 'vintage'. OmniGen v2 is the winner for this specific invitation challenge because it actually communicates the event information, whereas FLUX.1 Krea (dev) fails at the fundamental purpose of an invitation despite its superior art.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent PBR textures with realistic subsurface scattering on the salmon.
- + Accurate rendering of the Japanese flag icon.
- + Very clean typography that follows the requested layout perfectly.
- − The diorama base is a bit plain and lacks material contrast.
OmniGen v2
- + Colorful and vibrant cartoon aesthetic.
- + Good 3D drop shadow on the text elements.
- + Clean miniature diorama base with layered colors.
- − The flag icon is incorrect, appearing as a red and yellow stripe rather than the flag of Japan.
- − The sushi rolls have slightly confusing geometry where the salmon meets the filling.
- − The background blue is quite saturated, losing some of the 'soft refined' feel requested.
Verdict: FLUX.1 Krea (dev) followed the prompt much more accurately, particularly regarding the flag and the requested PBR materials, producing a highly polished and professional-looking 3D render. OmniGen v2 created a pleasant cartoon scene but failed on the specific detail of the Japanese flag and had less realistic textures on the food.
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.”

AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent fur texture rendering
- + Dynamic and natural action poses
- + Effective use of lighting and depth of field
- − Failed to include a rabbit, providing two cats instead
- − Some anatomical confusion on the cat jumping
OmniGen v2
- + Successfully included different animal types
- + Wibrant and colorful lighting
- − Failed the photorealistic requirement, appearing like a cartoon or 3D render
- − Anatomical issues with the animals' legs and paws
- − Lacks the fine fur detail requested in the prompt
Verdict: FLUX.1 Krea [dev] produces a much higher quality, realistic image that feels like a masterpiece, though it missed the specific combination of animals by including two cats and no bunny. OmniGen v2 failed the primary stylistic instruction for photorealism, resulting in a low-quality, illustrative look with significant AI artifacts.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent woodcut/engraving texture that fits the vintage aesthetic.
- + Beautifully rendered ribbons and cloche details.
- + Highly cohesive composition with a sophisticated color palette.
- − Spelling error in the main name, rendering it as 'Café Flanelín' instead of 'Caffè Florian'.
- − Extra nonsensical text at the bottom.
OmniGen v2
- + Successfully achieves a clean, minimalist vector style.
- + Accurately represents the requested 'Est. 1720' text.
- + Strong contrast with bold, legible typography.
- − Misspelled the name as 'CAFFFLORIN' by merging words and dropping letters.
- − The cloche dome design is very basic compared to the artistic quality of the competitor.
Verdict: Both models failed to spell the brand name correctly, but FLUX.1 Krea (dev) produced a far more professional and aesthetically pleasing design that felt like a true vintage emblem. OmniGen v2 captured the 'minimalist' aspect well but the resulting logo felt overly simplistic and lacked the technical polish of the line work seen in FLUX.1.
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.”
FLUX.1 Krea [dev]
OmniGen v2
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent primary title rendering with clean font.
- + Follows the NASA color palette perfectly.
- + Includes icons for Saturn V, Earth, and the Moon surface as requested.
- − Nonsensical iconography for several steps including 4 people and astronauts in space instead of orbit/trajectory icons.
- − The numeric sequence 1-2-3-6-4-0-5 is completely illogical and messy.
- − Includes a planet with rings (Saturn) which was not in the prompt and is irrelevant to Apollo 11.
OmniGen v2
- + Stronger infographic layout with a clean grid and consistent typography.
- + Captures the 'modern vector' style with minimalist geometric icons.
- + Correctly incorporates the requested 'Tranquility' text at the bottom.
- − Failed to spell 'Apollo 11' correctly, outputting 'Apolo 17' instead.
- − Text throughout the infographic contains heavy garbling and spelling errors.
- − The icons are highly abstract and don't clearly represent the specific mission steps requested.
Verdict: Both models struggled significantly with the complex 6-step infographic requirement, but OmniGen v2 produced a more authentic 'infographic' layout that looked professional from a distance. FLUX.1 Krea [dev] had better title text and colors, but the composition and numbering were chaotic and included irrelevant imagery like a ringed planet.
