Seedream 5.5: Edits That Hold for Round After Round

Seedream 5.5 changes the part you point at and leaves everything else pixel for pixel — so a product shot survives a background swap, a color change and a relight without drifting. Describe the edit below and run it here: no API key, 4 credits per 1K image.

What Changes After the First Edit

Change One Object, Keep the Whole Room

The pixels outside your selection stay put. Seedream 5.5 takes the object you name, turns it into what you describe, and leaves the walls, shadows and crop exactly where they were. Interior mockups, catalog updates and menu photography can swap a single prop without a reshoot that redoes the whole set.

Up to Ten References in a Single Edit

Ten photos can go into a single edit. Seedream 5.5 reads a mug, a shirt and a board attached together, then places them in one scene under a shared light source — a shorter path than describing four products in words and hoping all four arrive.

Frames Built for the Ratio, Not Cropped After

Eight ratios cover a square feed post, a 4:3 listing image, a 9:16 story and a 21:9 banner. Seedream 5.5 composes for the frame you choose, so a launch graphic does not lose its subject to a center crop when it moves between placements.

Materials and Light That Read as Real

Natural lighting, finer materials and more refined skin texture are the visible difference in close work: brushed metal keeps its grain, plaster keeps its pitting, fabric keeps its weave. That is what lets a frame from Seedream 5.5 sit beside a photographed one in the same catalog.

Costs You Can Predict Before You Run

Five reference photos at 1K come to 14 credits in Seedream 5.5. The arithmetic stays fixed — 4 credits at 1K, 6 at 2K, 2 per reference photo — and the counter confirms the total before the task starts.

What Is Seedream 5.5?

Seedream 5.5 is ByteDance's multimodal image model, released in November 2026. It handles text-to-image generation and reference-based editing, returns 1K or 2K output across eight aspect ratios, and accepts up to ten reference photos per edit. The claim that matters is consistency across rounds: repeated edits stay targeted, and untouched areas survive pixel for pixel.

Edits That Stay Where You Put Them

Furniture swaps, hairstyle changes, object repositioning and watch-face updates all work as repeatable tasks inside Seedream 5.5, with the pixels around each edit left intact from one round to the next.

Generation and Editing Together

Seedream 5.5 has two modes on one model — generating from a prompt and editing from references — so a first draft and its fifth revision share a visual language.

Eight Ratios, Two Resolutions

Pick from 1:1, 4:3, 3:4, 3:2, 2:3, 16:9, 9:16 or 21:9, then choose 1K or 2K output. Edits add an auto option that keeps the source frame.

4 Credits for a 1K Image

A 1K generation costs 4 credits and a 2K generation costs 6, with each reference photo in an edit adding 2.

How to Run a Multi-Turn Edit

Four steps from an empty prompt box to a finished asset, with references optional.

Describe the image or the edit

For a new picture, write the subject, composition, light and mood. For an edit, name the part to change and state plainly that everything else stays as it is.

Attach reference photos

Add the product shots, character sheets or style boards the result should build on — up to ten. Each reference adds 2 credits, so attach only what the edit actually needs.

Choose a ratio and resolution

Pick one of eight ratios and 1K or 2K output. Edits default to auto and keep the source frame; new generations default to 1:1 at 2K.

Review, revise, download

Check the result against the original, request the next change in the same session, and download once the detail holds up. Revisions stay on the part you named.

Where the Model Fits

Anyone who ships several versions of the same image gets the most out of Seedream 5.5.

Ecommerce catalog updates

Swap a colorway, change a prop or restage a background while the item keeps its shape, label placement and proportions. Seedream 5.5 holds those details across the whole set rather than re-deciding them per image.

Campaign variants from one master

Start from a finished key visual, then produce regional and seasonal variants by editing the parts that change and leaving the approved composition intact.

Editorial and blog visuals

Generate a hero image for an article with Seedream 5.5, then adjust a detail that clashes with the copy without regenerating the scene and losing the parts that worked.

Product concepts and packaging

Explore finish, material and label options on the same object, so a packaging study compares real alternatives built on one design.

Characters across a series

Feed a character sheet in as a reference and change outfit, pose or scene while the face and styling stay recognizable from image to image.

Presentation and client work

Take a client note as a direct instruction — move this, recolor that — and return a revised frame that keeps the rest of the approved design in place.

How It Compares With Earlier Rounds

The difference shows up on the second and third edit, where earlier versions drift.

	Earlier Seedream versions	Seedream 5.5
Repeat edits	Detail and color drift as rounds accumulate	Untouched areas preserved pixel for pixel between rounds
Reference photos per edit	Fewer references, or none on earlier text-to-image endpoints	Up to ten in one edit
Output size	One resolution, or a fixed 4K tier	1K or 2K, priced separately
Aspect ratios	A shorter ratio list	Eight ratios, plus auto for edits
Materials and light	Flatter lighting, softer surface detail	Natural lighting, finer material and skin texture
Where it runs	Vendor playground or API integration	Runs here, on one credit balance shared with every model
