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
FLUX.1 Krea [dev]
- + Excellent depiction of spatial depth and reflections on the glass cube.
- + Professional, moody lighting that creates a realistic atmosphere.
- + The blue sphere has an interesting, detailed marble-like texture.
- − The plant in the background is very dark and lacks clarity.
- − The glass cube has a very thick base that makes it look more like a container than a simple cube.
GPT Image 2
- + Perfect adherence to all prompt elements, including the specific window light source.
- + High clarity and sharpness across all objects including the plant.
- + Very clean and realistic wood grain on the table.
- − The blue sphere looks a bit like a matte toy ball rather than a sophisticated object.
- − The reflection on the bottom of the cube is slightly inconsistent with the sphere's position.
Verdict: Both models followed the prompt perfectly, but GPT Image 2 is the winner due to its superior lighting and clarity. While FLUX.1 Krea [dev] captured a more artistic and moody aesthetic, GPT Image 2 provided a much clearer view of the background plant and more realistic textures on the book and table.
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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent depiction of motion blur on passing cars
- + Strong adherence to the 'light rain' and 'wet pavement' atmosphere
- + Captures an 'imperfect framing' that feels like a genuine street photo
- − The man is holding the bike rather than actively 'repairing' it
- − The bicycle geometry is slightly distorted around the handlebars
GPT Image 2
- + Stronger adherence to the 'repairing' action with tools visible
- + Excellent skin texture and realistic, non-stylized details
- + Better bicycle anatomy and authentic Japanese street signs
- − Lacks the requested motion blur on the passing cars
- − The rain is barely visible compared to Model A
Verdict: FLUX.1 Krea (dev) captures the requested atmospheric elements like motion blur and rain perfectly, though the man is simply standing with the bike. GPT Image 2 provides a more literal interpretation of 'repairing' with a toolbox and a crouching pose, though it ignores the motion blur requirement. FLUX.1 Krea (dev) is preferred for better following all aesthetic and technical photography constraints of the prompt.
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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent depiction of ornate, high-contrast engraved armor
- + Great execution of the bokeh sparks and dark cinematic lighting
- + Precisely follows the metal and leather texture requirements
- − The blood/dirt on the face looks slightly digital and paint-like
- − The braids are very rigid and symmetrical, looking somewhat artificial
GPT Image 2
- + Incredible lifelike skin texture with realistic dirt and faint scarring
- + Highly complex and natural-looking hair braiding with integrated beads
- + Exceptional use of natural warm lighting and shallow depth of field
- − The armor texture is more weathered/gritty than 'ornate' compared to model A
- − Slightly less emphasis on the specific 'bokeh sparks' requested
Verdict: Both models performed exceptionally well, but GPT Image 2 creates a more believable and 'lifelike' person with superior skin and hair textures. FLUX.1 Krea [dev] has more striking, high-contrast armor engravings and better bokeh sparks, but GPT Image 2's overall composition and realism make it the stronger portrait.
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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Strong composition for a single-page flyer layout
- + Effective use of grid-based food photography
- + Professional shadow and lighting effects on the paper

GPT Image 2
- + Perfectly legible English text with realistic menu descriptions
- + Highly professional graphic design with icons and consistent branding
- + Strict adherence to all prompt elements including specific sections
- − Layout is slightly crowded horizontally
- − Some minor repetition in the food descriptions
Verdict: GPT Image 2 is the clear winner as it produces a fully functional, legible menu with excellent graphic design elements and perfect English text. FLUX.1 Krea [dev] creates a visually appealing layout, but fails completely on text legibility and missed the specific request for a pizza section, instead repeating the appetizer heading.
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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Clean, readable text for the main titles
- + High-quality, realistic food textures
- + Strong studio-lighting aesthetic
- − Failed to apply 'fiery, glowing effect' to the text
- − Placement of the '€6.99' price is not in a starburst as requested
- − Minor AI hallucinations in fine print at the bottom
GPT Image 2
- + Perfectly followed the instruction for fiery, glowing text effects
- + Dynamic explosion effect with realistic sauce splashes and flying embers
- + Correctly placed the price inside a fiery starburst
- − Composition feels slightly more cluttered compared to the clean layout of A
- − Slightly less photorealistic lighting on the top bun compared to Model A
Verdict: GPT Image 2 is the clear winner as it followed every specific stylistic instruction in the prompt, particularly the fiery glowing text and the starburst price tag. While FLUX.1 Krea produced a very clean and professional food shot, it ignored the specific lighting requirements for the typography.
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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent chalk dust textures on the board surface
- + High frame and image clarity
- + Clean layout
- − Significant spelling errors ('Gruffle', 'Loman', 'Uhvcuations')
- − Text looks more like a digital font than actual human handwriting
- − Repeated menu item variations instead of following the prompt list
GPT Image 2
- + Perfect text accuracy for all requested menu items
- + Highly realistic chalk texture within the letters
- + Convincing human handwriting with natural variations as requested
- − Slightly lower contrast between text and board
- − Layout is a bit tight on the right margin
Verdict: GPT Image 2 is significantly better as it strictly followed the text requirements and captured the requested 'handwritten' feel with grain and texture, whereas FLUX.1 Krea [dev] failed on spelling and produced text that looks like a clean digital font. GPT Image 2 also correctly interpreted the truncated prompt to complete the 'Brown Butter' item accurately.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Excellent cinematic lighting and composition.
- + Highly detailed rendering of the space suit and Earth background.
- + Anatomically correct horse features.
- − Failed the negative constraint: the astronaut is riding the horse instead of the other way around.
GPT Image 2
- + Perfectly followed the difficult negative constraint of having the horse on top.
- + Creative use of a saddle and reins placed on the human astronaut.
- + Realistic textures on both the space suit and the horse fur.
- − The astronaut's hands/gloves have an incorrect number of fingers.
- − The horse's front legs are truncated or merge awkwardly into the astronaut's shoulders.
Verdict: While FLUX.1 Krea [dev] produced a much more visually stunning and cinematic image, it completely failed to follow the specific spatial instruction. GPT Image 2 successfully interpreted the 'horse on top' requirement, creating a surreal and humorous scene that directly addresses the prompt's core challenge despite some 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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Includes all elements of the prompt including additional passengers
- + Crisp lighting and clear textures
- + Capybara expression is very calm and fits the 'professional' description
- − The passenger's face in the background has some warping around the phone
- − Capybara's paws are not both clearly on the steering wheel as requested
GPT Image 2
- + Excellent photorealism with shallow depth of field
- + Anatomically correct paws on the steering wheel as requested
- + Superior lighting and bokeh effect in the Manhattan background
- − The passenger in the back is quite blurry
- − The cap is a bit oversized for the capybara's head
Verdict: GPT Image 2 is the preferred output because it delivers a significantly more cinematic and photorealistic result with better adherence to the specific 'both front paws on the steering wheel' instruction. While FLUX.1 Krea (dev) captures the scene well, it feels more like a composite image compared to the seamless lighting and professional composition found in the GPT Image 2 version.
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.”
AI Judge Analysis
FLUX.1 Krea [dev]
- + Features a very clean, high-contrast illustration style
- + Includes all requested elements like the jack-o-lantern and bats
