Seedream 5.0 Pro

ByteDance's flagship image model for dense layouts and pixel-level retouching, with click/lasso/recolor editing and native rendering in a dozen-plus languages.

Released 2026-07-08 · Last checked 2026-09-28

What’s new

  • Dense layouts in one pass: ByteDance says it produces near-ready professional layouts for infographics, posters and UI/product mockups packed with both data and text.
  • Pixel-level interactive editing: point selection, lasso, sketch coloring, recoloring, material swaps, layer separation and multi-image fusion — fix one part instead of regenerating the whole image.
  • More realistic materials and lighting: better skin and material rendering, plus support for photography-style camera moves.
  • A dozen-plus languages, natively: French, German, Russian, Japanese, Korean, Spanish, Arabic and more can be typed directly, no translation to English needed first.

What it’s good for

  • Text-and-data-heavy posters, infographics and UI/product mockups that need to come out already laid out.
  • Commercial retouching where you keep returning to fix one detail: a color, a material, one isolated layer.
  • Localized marketing assets for global markets, generated directly in the target language.

Prompting tips

  • Cover five elements: subject, action/pose, environment, style, and technical details (lighting/camera/resolution) — the structure Dreamina's own guide recommends.
  • Put in-image text in quotes: e.g. text reading "Good Morning Café" renders more reliably than unquoted text.
  • Name the region when editing: with point-select or lasso edits, say exactly where and what should change.
  • Spell out materials and lighting: not "nice light" — say what material, what light source, from which direction.
  • Tag each reference image: note what person or style each of up to 10 reference images is for.
  • Expect one image per run: this tier doesn't support n>1, so generate variations one request at a time.

Known limits

  • Only one image per request — no n>1, no sequential batches, no streaming.
  • Up to 10 reference/input images; more than that is rejected.
  • ByteDance says fine-grained text rendering and pixel-level editing consistency still have room to improve.

Using it in Nomi

On the generation canvas, add a image card, pick “Seedream 5.0 Pro” in the model picker and choose a mode (Text to image, Image editing). Add your references, write the prompt and generate. In the storyboard you can pick it per shot. The first time, connect any one of the providers above under Settings → Models.

Download Nomi
Choose the version for this computer

Nomi downloads directly when the platform is known. If the Mac chip cannot be detected reliably, choose the matching installer.

First launch on macOS

The current macOS build is not Apple Developer ID signed or notarized. Only use download links on this site or in the official Nomi GitHub repository.

  1. Download the matching DMG and drag Nomi to Applications.
  2. In Finder, right-click Nomi in Applications, choose Open, then confirm Open.
  3. If it is still blocked, open System Settings → Privacy & Security, find Nomi, and click Open Anyway.

Only if macOS says Nomi is “damaged”: confirm the installer came from an official link above, then open Terminal and run:

xattr -dr com.apple.quarantine "/Applications/Nomi.app"

You do not need to disable Gatekeeper globally, and should not do so.
