What is it?

Seedream v4 Edit Sequential is ByteDance's image-to-image model for editing a source image and generating a sequence/group of consistent outputs in one pass. It’s built for high feature retention (identity, logos, layout) and cross-image style continuity—ideal for matched sets, story panels, or product variants.

What makes it stand out?

  • I2I + sequential in one pipeline – Edit a single source and produce N coherent images (series/panels) without switching models.
  • Five core strengths – Precise instruction editing, high feature retention, deep scene understanding, ultra-fast inference, ultra-high-res output.
  • Consistency controls – Strong identity/style preservation across all images in the set.
  • Rich edit ops – Add/remove elements, attribute/style change, structural tweaks (e.g., pose/face swap), texture/brush/frame edits.

Designed for

  • Commercial design — Posters, apparel, packaging, e-commerce sets; fast, brand-safe varianting.
  • Entertainment IP — Character look-dev, key art sequences with locked identity.
  • Fine art & Illustration — Multi-piece series with coherent palette and linework.
  • Architecture — Material/lighting variations across consistent viewpoints.
  • Brand content — Campaign sets and social carousels with fixed logo/palette.

How to use

  1. Inputs: Upload several source images.
  2. Prompt: Write the instruction and repeat the same N in text (e.g., “a series of N images / Panels 1–N”) to lock count & continuity.
  3. Count: Set max_images = N for the number of images.
  4. Control the size: the max size is 4096 * 4096.
  5. Generate → review → iterate (reuse or change seed for A/B).

Please Note: Declare the number of images twice — max_images = N and inside the prompt!

Price

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

Prompting guide

  • Edit instruction (per set) Replace [object A] with [object B]; keep [logo/identity/features]; preserve [lighting/style].

  • Sequential consistency (count locked) Generate a series of [N] edited images (Panels 1–[N]) from the source, maintaining the same [character/product/logo] identity, palette, and composition style.

    Panel 1 — [edit/shot] Panel 2 — [edit/shot] ... Panel N — [edit/shot]

  • Terminology Use precise, domain-native terms (photography, fashion, architecture) to match expectations.

Example (product variant set, N=4)

Set max_images = 4 and use:

Generate a series of 4 edited images (Panels 1–4) from the source photo, keeping the same shoe model and logo placement. Maintain identical angle, lighting, and background; change only the colorway per panel:

Panel 1 — classic white + black swoosh

Panel 2 — navy + gold accents

Panel 3 — matte red + white outsole

Panel 4 — forest green + gum sole

Ensure consistent proportions, stitching detail, and material texture across all 4 panels.

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)
