Fashion editorial
Fashion editorial
Prompt: High-fashion editorial photograph of a model in a sculptural cobalt-blue gown with exaggerated pleats, standing in a brutalist concrete stairwell, one shaft of hard sunlight cutting diagonally across the scene, fabric catching the light while the rest falls into deep shadow, medium-format camera look, 80mm lens, bold composition with strong geometry, fashion magazine quality.
Character illustration
Detailed character scene
Prompt: Detailed painterly illustration of an elderly clockmaker in his cluttered shop at night, leaning close over an open pocket watch with a jeweler's loupe, hundreds of brass gears and hanging clocks around him glowing in warm lamplight, his cat watching from a shelf, rich storybook detail in every corner, cozy amber palette, square composition.
Large-format detailed scene
Prompt-rich city composition
Prompt: Ultra-detailed cinematic cityscape of a rainy evening in a dense old-town shopping street: paper lanterns and neon signs reflecting on wet cobblestones, a ramen shop with steam curling from its window, commuters with transparent umbrellas, a cyclist splashing through a puddle, layered depth from foreground lanterns to a misty temple gate far down the street, atmospheric teal-and-amber grade, photorealistic, rendered at 4K with crisp fine detail throughout.
Cover design
Magazine cover concept
Prompt: Magazine cover concept for a fictional food quarterly: overhead shot of a long harvest table crowded with roasted vegetables, breads, and shared plates, hands reaching in from the edges, warm candlelit tones. Render the masthead "GATHER" in large cream serif capitals across the top, and one cover line "THE SLOW TABLE ISSUE" in small type at the lower left. Realistic print magazine layout with confident hierarchy.
Product lifestyle image
Product lifestyle mockup
Prompt: Lifestyle product photograph of a pour-over coffee set — glass carafe, ceramic dripper, and a small bag of beans with a blank kraft label — arranged on a sunlit kitchen windowsill with trailing pothos leaves, steam rising softly from the carafe, warm morning light, calm slow-living aesthetic, realistic textures, square format for a web shop.
Nature editorial
Wildlife editorial spread
Prompt: Editorial wildlife photograph of a puffin standing on a cliff-top carpet of pink thrift flowers, beak full of silver sand eels, soft overcast light, the sea a muted blue-gray blur far below, crisp feather and flower detail in the foreground, medium telephoto compression, nature-magazine double-page composition with breathing room on the right.
Seedream V4 is ByteDance's layout-aware image model: it plans where headlines, subjects, and negative space go instead of scattering elements, which is why posters and covers come back with a hierarchy you can actually ship.
On RenderFlow AI, width and height each scale from 1024 to 4096 pixels at a flat 5 credits per image, with a seed field for locking compositions — enough room for print-adjacent key art and a week of social cutdowns from one master.
Pick width and height first — 2048×2048 is the default, but posters usually want a tall frame like 2048×3072 and banners a wide one like 4096×2048. Sizing early matters because Seedream V4 composes to the frame you give it.
Name the format (concert poster, magazine cover, product key art), the visual hierarchy, and the mood. Then add the exact words in quotes and say where each line sits: masthead across the top, subtitle below, footer small.
Review the first output for type errors before touching the art. If one line is wrong, shorten it or cut the number of text elements and regenerate — rewriting everything usually costs you a layout that already worked.
When a composition lands, copy its seed into the Seed field and change one variable at a time — palette, background, or a single line of copy. Locked seeds turn one good poster into a coherent campaign set.
For high-volume social variations where 4K is wasted, run the same prompt on Seedream 3.0 at 4 credits and smaller sizes. Keep V4 for the master visuals that need the big canvas.
Width and height are set independently from 1024 to 4096 pixels per side — anything from a 1024×4096 banner strip to a full 4096×4096 square. The default is 2048×2048, and the 5-credit price stays flat whatever size you pick.
V4 raises the canvas ceiling from 2048 to 4096 pixels per side and brings noticeably stronger layout and in-image text handling. Seedream 3.0 remains available at 4 credits with a guidance-scale control, which suits established Seedream 3 workflows and budget bulk generation.
Yes — short quoted strings like headlines, dates, and labels are one of its strengths, especially when you say where each line sits in the layout. Long paragraphs and many separate text blocks still risk letter errors, so keep copy tight.
GPT-Image-2 offers three quality tiers and stricter accuracy on small copy, while Seedream V4 counters with a bigger native canvas (4096px per side) and a flat 5-credit price. For an important poster, run the same headline test on both and keep the winner.
Shorten the offending string, reduce the number of separate text elements, and describe placement explicitly ("masthead across the top"). Then regenerate with a fresh seed — rewriting the whole prompt usually sacrifices a layout that already worked.
