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.2 [dev] Turbo
- + Excellent glass physics, featuring realistic dust/scratches and light refraction.
- + The plant is clearly visible through the glass as requested, interacting logically with the refractive edges.
- + Very high level of photorealism in the wood grain and book texture.
- − The sphere has a slight blue reflection on the floor of the cube that is a bit intense.
- − The composition feels slightly crowded compared to the cleaner look of the other image.
FLUX.2 [pro]
- + Clean, minimalist aesthetic with very sharp edges on the glass cube.
- + Excellent lighting that feels soft and diffuse, consistent with window light.
- + Perfectly centered sphere and well-balanced composition.
- − The plant is heavily blurred and almost disappears behind the cube, failing the 'partially visible through glass' prompt detail compared to Model A.
- − The glass lacks the subtle imperfections that make Model A look like a real photograph.
Verdict: Both models followed the complex spatial instructions perfectly. FLUX.2 [dev] Turbo created a more convincing, lived-in photograph with realistic glass refractions and a better rendering of the plant through the glass, whereas FLUX.2 [pro] produced a cleaner, more commercial-style render but sacrificed the visibility of the plant through the glass.
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.2 [dev] Turbo
- + Excellent depiction of motion blur from passing cars
- + Strong adherence to the 'imperfect framing' prompt with a centered, slightly cluttered composition
- + Authentic rain textures including visible drops and wet asphalt reflections
- − The rear tire of the bicycle is clipping through the ground in the reflection area
- − The bicycle geometry is slightly warped near the handlebars
FLUX.2 [pro]
- + Incredible skin texture and facial detail for the subject
- + Very realistic bicycle mechanics and physical interaction with the wheel
- + Masterful use of shallow depth of field and bokeh in the background
- − Lacks the requested 'motion blur from passing cars'
- − The framing feels a bit too 'perfectly' staged despite the request for imperfect framing
Verdict: Both models followed the prompt well, but FLUX.2 [dev] Turbo captured the specific 'candid' atmosphere and 'motion blur' requested more effectively. However, FLUX.2 [pro] produced a much higher quality image in terms of human anatomy, skin texture, and realistic bicycle mechanics, making it the more visually impressive result despite missing the motion blur detail.
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.2 [dev] Turbo
- + Sharp focus and excellent resolution on facial features and armor textures.
- + Highly detailed engraving on the plate armor with a more realistic metallic sheen.
- + Accurate interpretation of leather straps and buckles with visible stitching and textures.
- − The beads in the hair look slightly more like plastic modern crafts compared to the overall gritty aesthetic.
FLUX.2 [pro]
- + Strong atmospheric lighting with warm torchlight highlights on the character's face.
- + Dynamic composition with a slightly angled perspective that adds to the battle-worn feel.
- + Good integration of scars and dirt, looking naturally seated on the skin.
- − The textures on the armor and leather straps are softer and less detailed than Image A.
- − The bokeh sparks are somewhat smeary and less defined.
Verdict: While both models perform exceptionally well, FLUX.2 [dev] Turbo produces a superior level of technical detail, particularly in the intricate engravings of the armor and the texture of the leather. FLUX.2 [pro] has slightly better atmospheric lighting, but loses out on the sharpness and tactile realism requested in the prompt for the leather and metal surfaces.
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.2 [dev] Turbo
- + Excellent adherence to the grid layout with clean, professional alignment.
- + Very high-quality food photography that fits a modern culinary aesthetic.
- + Superior rendering of legible text for item names and pricing.
- − Logical inconsistency in pricing (e.g., $260 for a pizza).
- − Food photos under 'Appetizers' primarily show pizzas.
FLUX.2 [pro]
- + Features more logical pricing for a casual dining establishment.
- + Includes helpful icons alongside section headers.
- + Good use of vibrant color accents to differentiate sections.
- − Text rendering is messy with typos like 'MINS' instead of 'Mains'.
- − Repeats the same menu items (Margherita Pizza) multiple times in several sections.
- − The layout feels slightly more cramped and less professional than the competitor.
Verdict: FLUX.2 [dev] Turbo produced a much more professional and visually appealing layout that looks like a real minimalist menu, despite some nonsensical high prices. FLUX.2 [pro] struggled with text accuracy, repeating the same dishes across every category and misspelling the section headers.
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.2 [dev] Turbo
- + Excellent front-facing composition that clearly shows the capybara's expression and paws on the wheel.
- + Very high levels of detail on the capybara's fur and the businesswoman's face.
- + Accurate text rendering on the taxi roof light.
- − The businesswoman is sitting in the front passenger seat instead of the requested back seat.
- − The paws have a slightly unnatural, almost human-like finger structure.
FLUX.2 [pro]
- + Perfectly adheres to the spatial prompt by placing the businesswoman in the back seat.
- + Realistic leather jacket texture and side-profile lighting.
- + Captures the 'bored' expression of the passenger very effectively within the background blur.
- − The side view makes it harder to see the capybara's expression compared to the other model.
- − The lighting on the capybara's face is a bit flat.
Verdict: FLUX.2 [dev] Turbo produces a more striking image with better facial details and textures, but it fails the spatial requirement of placing the passenger in the back seat. FLUX.2 [pro] followed the prompt instructions more accurately regarding the seating arrangement, making the scene feel more like a genuine taxi ride. FLUX.2 [pro] is the winner for its superior prompt adherence despite the slightly less detailed fur texture.
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.2 [dev] Turbo
- + Includes all four requested animals: golden retriever, tabby kitten, bunny, and fox kit.
- + Excellent composition with animals interacting in a cohesive group.
- + Captures the 'dew sparkles' very well with floating droplets throughout the scene.
- − The kitten's facial expression is slightly unsettling and less realistic than the others.
- − The lighting, while warm, lacks the distinct 'god rays' requested in the prompt.
FLUX.2 [pro]
- + Beautiful golden lighting with clear god rays filtering through the background tree.
- + Highly expressive and anatomically charming faces on the puppy and fox.
- + Excellent fur texture and sharp detail on the animals' features.
- − Failed to include the requested baby bunny animal.
- − The puppy's raised paw has an unusual number of pads/toes.
Verdict: FLUX.2 [dev] Turbo followed the prompt more accurately by including all four animals, whereas FLUX.2 [pro] missed the baby bunny. However, FLUX.2 [pro] produced a much more atmospheric image with superior lighting and 'god rays' that better captured the requested aesthetic. FLUX.2 [dev] Turbo is the winner for prompt adherence, while FLUX.2 [pro] is more visually stunning despite the missing subject.
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.”
AI Judge Analysis
FLUX.2 [dev] Turbo
- + Perfect adherence to typography including the grave accent on 'Caffè'.
- + Excellent vintage texture and banner design.
- + Strong vector emblem composition with balanced hierarchy.
- − The steam lines are a bit thin compared to the bold weight of the logo.
FLUX.2 [pro]
- + Clean, modern-meets-vintage vector aesthetic.
- + Effective use of shading and negative space on the cloche.
- − The 'Est. 1720' banner is very small and lacks visual impact.
- − The overall composition feels a bit fragmented with the split circle.
Verdict: Both models followed the prompt instructions accurately, but FLUX.2 [dev] Turbo produced a more cohesive and professional-looking logo. FLUX.2 [dev] Turbo's use of a large, detailed banner for the date and the bold, correctly accented typography makes it look like a finished brand identity, whereas FLUX.2 [pro] has some scale issues with its banner and text placement.
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.”
AI Judge Analysis
FLUX.2 [dev] Turbo
- + Excellent typography and accurate, legible text for the mission steps.
- + High-detail illustrations of the Saturn V and Lunar Module.
- + Includes accurate names and silhouettes for the three astronauts.
- − The layout is a bit cluttered and redundant, repeating the Earth icon and Translunar label.
- − Icons for the Earth and Moon are more detailed/realistic than 'flat vector style' requested.
FLUX.2 [pro]
- + Superior infographic structure with clear, linear steps and horizontal dividers.
- + Perfectly adheres to the requested 'flat-vector style' with crisp lines and consistent iconography.
- + Excellent use of the specified NASA-inspired color palette.
- − The placeholder body text under the headings is gibberish.
- − Missed the final 'Landing' step label, though the imagery is present.
Verdict: FLUX.2 [pro] followed the stylistic instructions much better, producing a clean, modern vector aesthetic with a logical linear flow suitable for an infographic. While FLUX.2 [dev] Turbo had better text accuracy and more detailed icons, its layout was messy and it failed the 'flat-vector' style requirement compared to the professional design produced by the pro model.
