Native 4K rendering, fourteen-frame sequential runs, and editing across ten references sit behind the Seedream v4 API, giving developers ByteDance's unified generation and editing stack through a single pay-as-you-go endpoint.

The Seedream v4 API renders text-to-image output at resolutions up to 4096 by 4096 pixels, with flexible dimensions starting from 1024 on either side. Every frame preserves fine texture, crisp edges, and controlled depth, so detail survives heavy cropping or upscaling. This makes it a dependable choice for large-format print, gallery visuals, and e-commerce shots that must hold up under close inspection.

Feed the edit endpoint one to ten source images and describe the change in ordinary text. The model can add, remove, replace, or restyle specific elements while keeping the original composition intact, so lighting and layout stay coherent. Designers rely on it for commercial retouching, background swaps, and fast iteration without rebuilding a scene from scratch.

Every Seedream v4 API mode, text-to-image, editing, sequential, and edit-sequential, runs through one OpenAI-compatible endpoint on Atlas Cloud. Access is available from Day 0 with transparent pay-as-you-go pricing at $0.03 per image and no subscription. Switch between generation and editing without new keys or SDKs, and scale usage straight from your existing stack.

Up to ten reference images can be blended in a single request, letting the model merge subjects, styles, and settings into one coherent result. Because identity and detail carry across inputs, characters and products stay recognizable from picture to picture. Teams use this to unify brand assets, build consistent casts, and assemble complex scenes that would otherwise demand manual compositing.

When a project needs more than one frame, the Seedream v4 API sequential endpoints return anywhere from one to fourteen images in a single call. Strict stylistic and character continuity holds the set together, so palette, lighting, and subject stay aligned across every frame. It is built for storyboards, character sheets, and campaign sets that must read as one family.

Built as a large-scale generative model, Seedream v4 interprets long, layered prompts and resolves how objects, people, and space relate. Complex briefs involving spatial arrangement or cultural detail translate into images that match the described intent rather than a loose approximation. This precision shortens the distance between a written concept and a usable first result.
The same prompt, generated by Seedream v4 and other leading image models: e-commerce hero image and concise control
Documentary street photography, the decisive moment a barefoot child leaps into a rain puddle in a narrow alley just after a downpour — captured at the peak of the jump, fully airborne and weightless, head thrown back, mouth open in a wild unposed laugh, arms flung out; beneath the launch foot the splash bursts upward into a luminous transparent crown of water, individual droplets suspended and frozen in mid-air. Late-evening low golden-hour backlight rakes low through the alley, rim-lighting the flying droplets and mist so their edges glow crystalline and translucent, catching the soaked cotton shirt clinging to the child's body and the wet strands of hair plastered to the forehead; the rain-slicked cobblestones mirror the warm orange sky. Low ground-level camera angle with the reflective water surface splitting the frame into layered foreground reflection and real subject; weathered red-brick walls converge as leading lines drawing the eye inward, large expanse of negative space above the child. Complementary color scheme of warm orange highlights against cool blue shadow. Rich real-world texture — wet stone grain, transparent beads of water, drenched fabric, damp hair. Shot on telephoto lens for compressed layered depth, natural fine film grain, authentic candid photojournalism, no staging, no over-rendering. 16:9 aspect ratio.

Impressionist thick-impasto oil painting, not a photograph and not a flat poster: a lively open-air seaside swimming pool blazing under harsh midday sun, seen from a high overhead vantage looking down onto a broad turquoise water surface where dozens of tiny sunbathers and swimmers are scattered as small confident dabs of paint, none blurring into mush — each figure a few decisive strokes. At the very center a single diver hangs frozen in mid-air, arms spread wide in a swallow dive, the splash beneath still forming and captured in heavy sculpted ridges of white and pale-blue oil paint — the decisive instant before the plunge, brimming with the noise and joy of high summer. Midday hard light shatters the water into countless glinting specular highlights and interwoven warm-and-cool reflections, and casts crisp short shadows from every swimmer and pool railing. Composition uses the colored ceramic pool-edge tiles and the painted lane lines as strong diagonal leading lines slicing across the frame, with a large calm expanse of open water as breathing negative space. Complementary color clash: turquoise blue set against warm ochre and coral orange, deck umbrellas and towels as punchy accents. Visible palette-knife texture, piled buttery brushwork, and thick impasto ridges catching the light are the soul of the image; loose, gestural, alla prima, in the spirit of Sorolla and Joaquín and early modern plein-air oil painters, saturated but clean color, no muddy tones, no glossy over-rendering. Wide horizontal landscape composition filling the entire frame, wide 16:9 aspect ratio, full-bleed.

From e-commerce catalogs and multi-frame storyboards to campaign key visuals and billboard-scale print, the Seedream 4 API carries one image pipeline across every stage of commercial creative work.
Generate photorealistic product shots from text, with Seedream 4 rendering fine material detail at native 4K resolution up to 4096 by 4096. Storefronts and detail pages gain studio-grade visuals without a physical shoot.
The Sequential endpoint produces a run of 1 to 14 frames that hold character and style continuity across panels. This lets studios draft storyboards, mood boards, and design sheets in one call.
Feed an existing photo to the Edit endpoint and reshape textures, lighting, or individual subjects through plain text commands. Retouchers iterate on commercial shots and swap product contexts while the original composition stays intact.
Edit Sequential turns one reference image into a batch of 1 to 14 on-brand variations sharing palette, lighting, and framing. Marketing teams roll out cross-platform key visuals that stay part of one campaign.
Faster inference and sharper spatial reasoning let art directors move from brief to rendered concept in seconds. Whether pitching a game world or a film sequence, teams explore more directions before committing budget.
Because output arrives at native 4K, artwork holds crisp typography and texture even when scaled to billboards or gallery prints. Print houses and outdoor campaigns receive files that survive close inspection at any size.

The Seedream 4 API provides programmatic access to Seedream v4, ByteDance's large-scale image model that unifies text-to-image generation and prompt-based editing in a single architecture. On Atlas Cloud you reach it through one OpenAI-compatible key and pay per image as you go, with Day-0 access to new releases.
From a text prompt or reference input, the model renders high-fidelity visuals across photography, illustration, and design aesthetics, and it can rework existing images through plain text instructions. Teams typically use it for product imagery, concept art, marketing creative, and multi-frame visual series.
Point your existing SDK at the Atlas Cloud endpoint with one OpenAI-compatible key and you can send a first request within minutes. Pricing stays transparent and pay-as-you-go, so there is no subscription to set up before you build. Start building today.
Atlas Cloud charges transparent pay-as-you-go pricing at $0.03 per generated image, with no subscription or minimum commitment. You are billed only for what you produce, and the rate holds whether you call the standard, Edit, or Sequential endpoints.
Output reaches up to 4K ultra-high-definition, roughly 4096 by 4096 pixels, which keeps fine detail intact for large-format print and high-precision design work. Lower resolutions and multiple aspect ratios are available when you want faster iterations or specific framing.
You can supply several reference images, up to ten, to steer character identity, color palette, style, or composition. This enables subject-consistent fusion, so the key details you care about carry across every output in a set.
The standard endpoint turns text into a single image, while the Edit endpoint transforms an existing image through text guidance for retouching and iterative design. The Sequential and Edit Sequential endpoints extend both modes into a batch of 1 to 14 images that hold style and character continuity, which suits storyboards and character sheets.
Consistency comes from cross-image rules that lock palette, lighting, and subject identity across every frame of a Sequential generation. If drift appears, reusing the same descriptors and reference images across requests keeps scenes and characters coherent.
Against its predecessor, Seedream v4 brings faster inference, stronger reasoning about spatial relationships, and a single pipeline that handles generation and editing without switching models. It ranks among the top performers on public image-editing benchmarks, which reflects its precision on complex, instruction-heavy prompts.
Yes, the images you generate can be used in commercial projects such as advertising, product pages, and print campaigns. Review the current licensing terms in the Atlas Cloud documentation if your use case carries strict compliance requirements.
