Seedream 5.5: edit only what you ask for
Seedream 5.5 is the November 2026 image model from ByteDance's Seed team. It writes clean text into pictures, outputs transparent PNGs, and changes only the part of an image you describe. On Buble you can prompt a new picture or edit up to ten reference images at 1K, 1.5K or 2K.
Pictures made with Seedream 5.5
Every image below is an unedited result from Buble, shown with the prompt that produced it. The poster and both cut-outs were made at 2K; the others at 1K. The model also adds things nobody asked for: the night market gained a neon sign with an invented word, and the poster picked up small slogan lines in its corners. Check every result before you use it.

Before and after: edits that leave the rest alone
Each edit sends a showcase image back as the only reference and asks for one change. Drag across a card to compare. In the poster, only the subtitle line moved: under one percent of the pixels changed noticeably, and the headline, saxophone and corner text are the same as in the source. Edits were run at 1K, so the poster came back smaller than its 2K source.
Edit instruction
Change only the sky to a warm sunset; keep everything else exactly the same
What it does
What Seedream 5.5 gives you on Buble
Two modes share the same controls, so an image you generate can go straight back in as the reference for the next edit.
Targeted editing
Upload one to ten JPG, PNG or WEBP files, up to 10 MB each, and describe a change. Areas the instruction does not mention are kept as they were.
Native transparent PNG
Set Format to PNG and Background to Transparent to get an image with a real alpha channel, ready for logos, stickers and product cut-outs without a separate remover.
Readable text
Quoted headlines, dates, prices and signs come back as written in the examples here, including a three-line menu with prices.
Three size tiers
1K, 1.5K and 2K. The first two cost the same on Buble, so 1.5K is a free step up for drafts; 2K gives the sharpest detail.
Auto ratio for edits
In Image to Image you can leave the ratio on auto and let the model keep the shape of your reference, or set a new one.
Prompting
How to brief Seedream 5.5
The model follows plain, specific instructions. These habits made the examples on this page.
Quote every word you want printed
Put headlines, prices and sign text in quotation marks. Words you do not quote may still appear, so say "no other text" when the layout must stay clean.
Use "change only" for edits
Start an edit with the one thing that should change, then list what must stay: the splash, the lighting, the layout. All three edits here were briefed that way.
Ask for transparency in two places
Choose Transparent in the Background control and write "no background" in the prompt. Transparency only works with PNG output.
Pick the ratio before you draft
Text to Image needs a fixed ratio. Choose 3:4 for posters, 16:9 for banners and 1:1 for logos so you do not crop the subject later.
Draft at 1.5K, finish at 2K
Iterate at 1.5K for 3 credits, then rerun the winning prompt at 2K for 5 credits when you need print or retina detail.
Number your references
When you upload several images, say which one supplies the subject and which the style, in upload order.
Use cases
Where Seedream 5.5 fits
These are the jobs the examples above were chosen to show.
Product colorways
Shoot one hero image, then make each color variant with a one-line edit instead of a new render.
Posters and event updates
Generate a poster with real headline text, then correct a date or venue without redrawing the design.
Logos, stickers and cut-outs
Export transparent PNGs that drop straight onto slides, packaging mockups and web pages.
Menus and signage
Create menu boards, price cards and shop signs where the words have to be legible.
Scene relighting
Swap a sky, time of day or weather while the street, people and props stay in place.
Iterative design reviews
Apply reviewer feedback one change at a time and keep the approved parts of the image untouched.

Workflow
From first draft to final file
Generate, review, then fix details with edits instead of starting over.
Step 01
Draft in Text to Image
Run two or three prompt variations at 1.5K and keep the best composition.
Step 02
Fix one thing per edit
Send the keeper back as the reference and change a single element: a color, a word, the sky.
Step 03
Repeat until it is approved
Each edit starts from the last result, so earlier fixes stay in place while you work through the list.
Step 04
Render the final at 2K
Rerun the final prompt or edit at 2K when the image is going to print or a large screen.
Step 05
Download PNG or JPG
Save the result from your Buble library; keep PNG when you need transparency.
