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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent texture on the red book cover
- + Very sharp image quality and high resolution
- + Sophisticated handling of light and shadows on the table
- − The glass cube has an unrealistic mirrored bottom surface that wasn't requested
- − The plant is mostly behind the cube but not visible 'through' the glass as naturally as the prompt implies
Seedream 4.0
- + Perfectly depicts the plant behind the cube visible through the glass panels
- + Adheres strictly to all spatial instructions in the prompt
- + Captures the 'soft window light' very effectively with a hazy atmosphere
- − The glass edges are slightly thick and look more like an aquarium than a minimalist cube
- − Slightly lower sharpness compared to the other model
Verdict: Both models followed the complex spatial prompt well, but Seedream 4.0 is the winner because it correctly placed the plant behind the cube so that it is viewed through the glass, whereas Imagen 4.0 Fast placed the plant slightly to the side. Imagen 4.0 Fast produced a higher resolution image with better textures, but Seedream 4.0 captured the requested composition more accurately.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent reflection quality on the wet pavement
- + Strong sense of 'imperfect framing' with the foreground bokeh frame
- + Highly realistic skin textures and lighting on the subject
- − Anatomical issues with the man's hands which appear mangled
- − The background cars lack the specific 'motion blur' requested
- − The red bicycle has some structural inconsistencies around the fork
Seedream 4.0
- + Includes visible motion blur on the passing car as requested
- + Detailed setting with tools on the ground and a basket on the bike
- + Captures an authentic candid 'street photography' atmosphere
- − The reflection in the puddle doesn't match the bike's structure accurately
- − The man's right hand is fused with the bike frame
- − The background bokeh is slightly painterly rather than strictly photographic
Verdict: Seedream 4.0 followed the prompt more accurately by including the requested motion blur on the car and a more natural candid scenario. While Imagen 4.0 Fast Generate 001 produced a more cinematic lighting and framing style, it failed to generate the motion blur and had more significant anatomical issues with the hands.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Features a realistic aesthetic with high clarity in the facial textures.
- − Prompt adherence is completely missing; it failed to generate a paladin, plate armor, braids, torchlight, or bokeh sparks.
- − The composition is a full-body shot in a forest rather than the requested close portrait.
Seedream 4.0
- + Excellent adherence to all prompt elements including engraved armor, braided hair with beads, and bokeh sparks.
- + Superb cinematic lighting with warm torchlight reflections and highly detailed textures on leather and cloth.
- + Lifelike eyes and well-executed battle-worn details like scars and dirt.
- − Slightly soft focus on some of the leather straps compared to the facial clarity.
Verdict: Imagen 4.0 Fast Generate 001 failed to follow the prompt entirely, producing a modern man in a leather jacket instead of a medieval paladin. Seedream 4.0 followed the prompt perfectly, delivering a high-quality, cinematic portrait that captures every requested detail from the engraved armor to the specific lighting effects.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent grid layout that feels like a real, professional restaurant menu.
- + Includes specific price points and item descriptions alongside categories.
- + Clean, modern aesthetic with effective use of colored accent bars and bold fonts.
- − Text consists of gibberish/latin placeholder instead of English words.
- − The food photos are repetitive, showing multiple very similar pizzas regardless of the category.
Seedream 4.0
- + Strong, clear rendering of the category titles 'Appetizers', 'Pizza', and 'Mains'.
- + Better variety of food photography shown, including salads and pasta.
- + High contrast and vibrant colors.
- − Lacks any actual menu content like item names or prices, looking more like a mood board.
- − The layout is cramped with images overlapping or cutting off awkwardly.
- − Fails to deliver a 'professional layout' requested by the prompt.
Verdict: Imagen 4.0 Fast Generate 001 provides a legitimate-looking menu structure with professional spacing and design elements, despite the placeholder text. Seedream 4.0 captures the food variety better but fails at the core task of creating a 'menu design,' as it lacks pricing, descriptions, and a coherent layout.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Perfect adherence to all text requirements including the specific '€6.99' price.
- + Excellent photorealistic detail on food textures like the bun and lettuce.
- + Clean, professional composition suitable for a real-world advertisement.
- − The 'exploded' effect is a bit static compared to the sense of motion in the competitor.
Seedream 4.0
- + Strong sense of dynamic motion with swirling effects and aggressive fire.
- + The fiery text effect is very vibrant and well-integrated into the atmosphere.
- − Failed the specific price requirement, displaying '€5.99' instead of '€6.99'.
- − The burger anatomy is a bit chaotic and less 'exploded layer-by-layer' as requested.
- − Text rendering on 'LIMITED TIME ONLY' is slightly less crisp than Model A.
Verdict: Imagen 4.0 Fast Generate 001 is the superior choice for this prompt because it followed every instruction perfectly, including the specific price text and currency symbol. While Seedream 4.0 offered a more dynamic and energetic composition, its failure to render the correct price and its slightly lower photorealistic fidelity on the burger components makes it less effective as a final advertisement.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent text legibility and spelling accuracy for almost all words.
- + Clean, centered composition within the frame.
- − The text style looks like a digital font rather than natural chalk handwriting.
- − Contains spelling errors like 'Octuphus' and 'Cookes'.
- − Lacks the requested 'cozy café' background, showing only the board.
Seedream 4.0
- + Perfectly captures the realistic chalk texture and natural variations in handwriting style.
- + Includes a realistic 'cozy café' background with shallow depth of field.
- + Follows the cursive title instruction much better than the competitor.
- − Slightly less legible in the lower text due to the heavy chalk smudging effect.
Verdict: Seedream 4.0 is the clear winner as it successfully captured the 'handwritten chalk' aesthetic, whereas Imagen 4.0 Fast rendered text that looks like a clean digital font. Seedream 4.0 also followed the environmental context of a 'cozy café' which Imagen 4.0 Fast ignored.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent anatomical details on the horse's musculature and skin texture
- + High-quality, cinematic background with ethereal nebula lighting
- + Crisp rendering of the astronaut's face and gear
- − Failed the negative constraint; the astronaut is riding the horse instead of the horse being on top
Seedream 4.0
- + Dynamic composition with a more vibrant, star-filled background
- + Realistic lighting reflections on the astronaut's visor
- + Good texture work on the astronaut's suit
- − Failed the negative constraint completely
- − The horse's front legs and hoof anatomy are slightly distorted
Verdict: Both models failed the specific instruction to have the 'horse on top' (a surreal role-reversal). Imagen 4.0 Fast Generate 001 is the preferred output because it features superior image quality, cleaner horse anatomy, and a more cohesive cinematic aesthetic compared to Seedream 4.0.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent fur texture and high visual resolution.
- + Interior lighting and reflections are well-rendered.
- + The capybara's head shape is anatomically accurate.
- − The capybara has five long, primate-like fingers instead of paws.
- − The businesswoman is sitting in the front passenger seat instead of the back seat.
- − The perspective makes the capybara look overly massive compared to the car.
Seedream 4.0
- + Correctly places the businesswoman in the back seat as requested.
- + The paws on the steering wheel look much more animal-like and natural.
- + Better captures the requested 'bored' expression on the passenger's face.
- − Lower overall resolution and slightly soft focus.
- − Text on the capybara's hat is nonsensical.
- − The capybara's head lacks the fine detail seen in the other model.
Verdict: While Imagen 4.0 Fast Generate 001 provides a much sharper, high-fidelity image with impressive fur detail, it failed the spatial instructions of the prompt by placing the passenger in the front seat and gave the capybara uncanny human-like fingers. Seedream 4.0 followed the prompt's layout much more accurately, correctly placing the passenger in the back and rendering animal paws, making it the more successful interpretation of the scene despite the lower image quality.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Clean and legible text for the event details
- + Polished graphic design aesthetic
- + Follows the square format and gothic title requirement
- − Includes a significant spelling error in 'IINVIITATION'
- − Missing the thorns requested in the border description
- − The jack-o-lantern and trees look more like digital clip-art than cinematic art
Seedream 4.0
- + Excellent cinematic lighting and moody atmospheric quality
- + Accurately includes all prompt elements including thorns and twisted trees
- + Spelling is generally more accurate across the image, despite some stylistic distortion
- − Text on the banner is slightly blurred and harder to read
- − The parchment paper effect is a bit cluttered around the edges
Verdict: Seedream 4.0 creates a much more atmospheric and cinematic image that perfectly captures the 'vintage gothic' mood requested, including the thorns and twisted trees which Imagen 4.0 Fast Generate 001 omitted. While Imagen 4.0 has cleaner layout for the event details, it suffers from a major spelling error in the title and lacks the visual depth found in Seedream 4.0.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent typography with clean white text that pops against the background.
- + Perfectly captures the 'minimal' diorama style requested.
- + Follows the isometric perspective and lighting instructions very accurately.
- − The sushi choice is very basic, featuring only two pieces.
Seedream 4.0
- + Features a more appetizing and varied selection of sushi types.
- + Excellent material rendering on the salmon and roe with realistic translucency.
- + Stronger 3D depth and shadow work on the base.
- − Black text for 'JAPAN' is slightly aggressive compared to the soft scene.
- − Incorrectly adds a second small pile of wasabi on the right side of the plate.
Verdict: Both models followed the prompt exceptionally well, including the specific text and flag requirements. Imagen 4.0 Fast Generate 001 provides a cleaner, more graphic design with superior typography, while Seedream 4.0 offers a more detailed and visually rich food scene with better PBR material work. Seedream 4.0 is preferred for its higher level of detail in the miniature elements and more convincing textures.
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
Imagen 4.0 Fast Generate 001
- + Excellent fur textures and clarity on all four animals.
- + High level of realism in the lighting and background daffodil field.
- + Accurate depiction of all four requested animals.
- − Missed the 'chasing butterflies' action requested in the prompt.
- − Static composition feels more like a portrait than a playful scene.
- − The 'tabby kitten' is rendered as a solid dark brown/black cat.
Seedream 4.0
- + Perfectly captures the action of 'playfully chasing butterflies and tumbling'.
- + Whimsical lighting with beautiful god rays and sparkling dew droplets.
- + Strong adherence to all prompt details including the tabby kitten markings.
- − The fox kit has a slightly cartoonish/oversaturated look compared to the other animals.
- − Some minor anatomical oddities in the puppy's paws during the action pose.
Verdict: Seedream 4.0 is the clear winner as it successfully captured the complex action and 'wholesome' energy of the prompt, including the specific butterfly and tumbling elements. While Imagen 4.0 Fast Generate 001 provides a high-quality, realistic portrait, it is quite static and failed to include the butterflies or the correct cat markings.
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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Clean vector aesthetic that perfectly matches the 'minimalist' prompt and 'emblem' style.
- + Excellent typography including the correct grave accent on 'Caffè'.
- + Balanced composition with sophisticated horizontal dividers and banner placement.
- − Includes some small, nonsensical filler text ('AFFD CARO') above the main title.
- − The steam effect is very faint and almost disappears against the background.
Seedream 4.0
- + Stronger representation of the 'subtle texture' on the background paper.
- + The cloche dome is more detailed with realistic highlights and shading.
- + Excellent rendering of the steam icon.
- − The text 'Caffé' uses an acute accent instead of the correct Italian grave accent 'Caffè'.
- − The arch of the top text feels a bit tight and less professional than a standard vector logo.
- − Illustrative style leans more toward a drawing than a 'minimalist vector emblem'.
Verdict: Imagen 4.0 Fast Generate 001 provides a superior logo design that feels authentic to the 'minimalist vector emblem' request, with professional spacing and correct Italian spelling. While Seedream 4.0 has beautiful textures and better steam, the overall composition and typo on 'Caffè' make it slightly less polished for its intended use as a restaurant 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.”
Imagen 4.0 Fast Generate 001
Seedream 4.0
AI Judge Analysis
Imagen 4.0 Fast Generate 001
- + Excellent adherence to the NASA-inspired color palette and minimalist flat-vector style.
- + Clean, modern layout that feels like a professional infographic.
- − Poor text rendering with spelling errors like 'APOLO' and 'MOOR'.
- − The logical flow of the diagram is confusing and doesn't follow a clear chronological path.
Seedream 4.0
- + Follows the requested 6-step chronological sequence very clearly.
- + Includes specific names like Armstrong, Aldrin, and Collins which adds to the infographic value.
- + Correctly illustrates icons like the Saturn V and Lunar Module according to the prompt.
- − Typos present in step 5 ('Surfcce') and the word 'Landing' is disproportionately large.
- − The dark blue background is a bit heavy compared to the requested 'clean' aesthetic.
Verdict: Seedream 4.0 is the winner because it successfully captured all six requested steps in a logical, chronological sequence and accurately depicted the specific icons requested, such as the Saturn V. While Imagen 4.0 Fast Generate 001 had a more sophisticated aesthetic, its layout was nonsensical and contained several major spelling errors.
