Generate a set of 5 consecutive illustrations: A close-up of a cheerful person with short, dark hair and wearing a yellow bucket hat and an orange t-shirt, holding up a light blue smartphone as if taking a selfie. Their backpack strap is visible over their shoulder. The background is slightly blurred but hints at an outdoor setting. The person from the first image is now shown from the waist up, their arm extended holding the smartphone, capturing a selfie. Behind them, a vibrant cityscape begins to emerge, featuring traditional Chinese architecture like a temple with a blue roof, and modern skyscrapers, including the recognizable Oriental Pearl TV Tower. A river flows in the midground. A wider shot reveals the full scene: the person is standing in a lush green park by a river. The impressive skyline of Shanghai stretches across the background, showcasing a blend of historical and futuristic buildings. A high-speed train is visible on an elevated track to the right, adding a sense of movement to the modern urban landscape. A panoramic view of the Shanghai cityscape from the park's perspective, without the person. The traditional temple, gleaming skyscrapers, the Oriental Pearl TV Tower, the river, and the elevated train track are all prominently featured. The park's greenery fills the foreground. A slightly zoomed-out panoramic shot, emphasizing the grand scale of the Shanghai skyline at sunset, with warm colors reflecting on the buildings and the river. The high-speed train is now a blur in the distance, and the park is a beautiful, serene space in the foreground.

Seedream V4 Sequential

What is it?

Seedream v4 sequential is ’s SOTA image model that use for sequential/group generation in one pipeline—built for cross-image consistency and rapid iteration.

Why choose Seedream?

  • All-in-one, multi-modal: T2I, edit, and multi-image sets without switching models.
  • Five strengths: precise instruction editing, high feature retention, deep understanding, ultra-fast inference, ultra-high-res output.
  • Speed: as little as ~1.8 s for a 2K image (T2I).
  • Powerful edits: add/remove objects, attribute & style changes, structural ops (e.g., face swap), texture/brush/frame edits.
  • Sequential consistency: maintains identity, palette, and layout across a set/series.

Designed for

  • Commercial design — Posters, apparel, packaging, e-commerce visuals; fast varianting and brand-safe edits.
  • Entertainment IP — Anime/film characters; style-consistent key art, poses, and look dev.
  • Art creation — High-res illustration, stylistic explorations, and series with coherent aesthetics.
  • Architecture — Concept renders, façade studies, material/lighting variations across sets.
  • Brand content — Campaign assets and social creatives with locked palette, logo, and identity.

How to use

  1. Write prompt: action + object + target feature. For sets add “a series of N images” and style locks.
  2. Set the parameter: size, max_images.

Price

  • $0.027 per image.
  • Total price = max_images * $0.027

Prompt Examples

  • Instruction edit: Replace [A] with [B]; keep [lighting/style]; preserve [logo/identity].
  • T2I coherent: A [subject] in [scene/time/weather], [camera/lens], [lighting], [style]; key props [X]; composition [framing].
  • Sequential set: Generate a series of [N] images of [subject/brand] in [scenario]; keep consistent [palette/logo/identity]; vary [poses/angles/backgrounds].

Note

Please set the max_image first, and then input how many images you want to generate in prompt! Such as:

  • max_image = 4.
  • Prompt: I want to generate 4 images... + (your prompt)

Seedream v4 Sequential API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seedream-v4/sequential with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Seedream v4 Sequential below.

HTTP example
# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/bytedance/seedream-v4/sequential" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "size": "2048*2048",
    "max_images": 1,
    "enable_base64_output": false,
    "enable_sync_mode": false
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].
Node.js example
// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("bytedance/seedream-v4/sequential", {

Seedream v4 Sequential API — Frequently asked questions

What is the Seedream v4 Sequential API?

Seedream v4 Sequential is a ByteDance model for image generation, exposed as a REST API on WaveSpeedAI. Seedream 4.0 by creates 4K images with editing, character/object consistency and sequential multi-image generation. Ready-to-use REST API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Seedream v4 Sequential API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedream-v4-sequential.

How much does Seedream v4 Sequential cost per run?

Seedream v4 Sequential starts at $0.027 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Seedream v4 Sequential accept?

Key inputs: `prompt`, `size`, `enable_base64_output`, `enable_sync_mode`, `max_images`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedream-v4-sequential.

How long does Seedream v4 Sequential take to generate?

Average end-to-end generation time on WaveSpeedAI is around 14 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Seedream v4 Sequential outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (ByteDance). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
