What is Seedream 5.5?
Seedream 5.5 is ByteDance's newest AI image model, released on November 9, 2026. It creates images from a text prompt and edits your own pictures, keeping everything you didn't ask to change. On Imgveo it renders 1K or 2K images from 6 credits each.
The release focuses on two jobs that earlier models found hard: editing the same picture many times without it drifting, and writing small, dense text that stays readable. If your work is posters, packaging, menus or step-by-step edits, this is the model to try first.

What's new in Seedream 5.5
ByteDance lists four improvements over Seedream 5.0. The figures below are ByteDance's own, from its launch post.
Steadier multi-round editing
Parts of the picture you don't ask to change stay put, pixel for pixel. ByteDance says an image holds together across as many as 100 rounds of edits.
Sharper small text
Dense text such as menus, labels and fine print comes out cleaner. ByteDance measured severe text errors in 0.4% of images and minor ones in 1.7%.
More realistic edits
Image-to-image results look more like real photos. ByteDance reports a +55.62% GSB (good-same-bad) score against Seedream 5.0 Pro in its own side-by-side tests.
Native transparent output
ByteDance says the model can render full and partial transparency on its own, with no background-removal step. There is no separate transparent-background switch on Imgveo yet.
Seedream 5.5 vs Seedream 5.0 Pro, Flash and Lite
All four run on Imgveo. Seedream 5.5 is the one to start with; the 5.0 models still win on price or on 4K.

Seedream 5.0 Lite

How to use Seedream 5.5 in 3 steps
No design software needed: the generator at the top of this page does the whole job.
01
Write a prompt or add a picture
Describe the image you want, or upload up to four reference images to edit or match. Seedream 5.5 is already selected.
02
Put any words in quotes
If the image needs text, write the exact words in quotation marks and say where they go. Describe everything else plainly.
03
Pick a size and generate
Choose 1K or 2K, an aspect ratio and up to four images. Download the PNGs, with no watermark.
The Edit Ladder: editing one image in rounds
Seedream 5.5 is built for step-by-step edits. Climb one rung at a time, change one thing per round, and the picture keeps everything you didn't touch. We call this the Edit Ladder.
IllustrationRound 1: the starting image
Edit instruction: A bright living room with a gray sofa, white walls and a round wooden coffee table
IllustrationRound 2: add plants
Edit instruction: Add green plants beside the sofa. Keep everything else the same.
IllustrationRound 3: repaint the walls
Edit instruction: Paint the walls sage green. Keep the furniture, the plants and the camera angle.
IllustrationRound 4: relight the room
Edit instruction: Change the light to a warm evening with the floor lamp on. Keep everything else.
Four rules for clean edits
Change one thing per round
One clear change is easy to check and easy to undo. Five changes at once make it hard to see what went wrong.
Say what stays
End each instruction with what must not change: “keep the furniture and the camera angle.”
Edit the latest result
Upload the image from the previous round as your reference, so every rung builds on the one before.
Restart when it drifts
If details start to wander, go back to the last good round instead of fixing the drift with more instructions.
Getting text right in Seedream 5.5
Text is where Seedream 5.5 improved most. Three habits get you clean lettering on the first try.
IllustrationPut the exact words in quotes
Quoted words are rendered as written. Everything outside the quotes is a description, not text to print.
Prompt: A chalkboard café menu titled "Café Menu" listing "Latte $4.50", "Cappuccino $4.75", "Americano $3.75", "Caramel Macchiato $5.25" and "Iced Coffee $4.50"
IllustrationSay where the words go
Name the place for each piece of text (a title on top, a label under each icon) so the layout is planned, not guessed.
Prompt: A clean infographic on a white background: three numbered steps with icons, titled "Boil Water", "Add Tea Leaves" and "Steep", one short line of text under each
IllustrationKeep each line short
A brand name and one short line read cleanly. Paragraphs of fine print add more chances for a typo.
Prompt: A jar of honey on a light gray background with a cream label that reads "Wild Flower Honey" in a classic serif font, small wildflowers around the jar
A Seedream 5.5 prompt formula
Four parts, in this order, cover nearly every image. Leave out the text part when the picture has no words.
- 01
Subject
What the image is of, with two or three concrete details.
- 02
Setting
Where it is: a surface, a room, a plain background or a scene.
- 03
Style
Photo, illustration, 3D or painting, plus the lighting.
- 04
Text
The exact words in quotes and where they appear.
Four templates to copy
Replace the words in brackets. The settings line shows what each template is written for.
Poster with a headline
Text to image · 3:4 · 2K
A [style] poster with the words "[headline]" in [font style] letters, [main image] below, [background color] background
Product shot
Text to image · 1:1 · 2K
[Product] on a [surface], [lighting], plain [color] background, product photography, no text
Edit a photo
Image edit · 3:4 · 2K
Keep the person in the first image exactly as they are. Change [what to change]. Keep the face, the pose and the background.
Packaging label
Text to image · 1:1 · 2K
A [product] with a label that reads "[brand name]" and "[second line]" in [font style] lettering, [background]
Three mistakes to avoid
01
Leaving the words unquoted
Without quotes the model can't tell the words to print from the words describing the scene.
02
Changing everything in one round
A big rewrite throws away what was already right. Edit in small steps instead.
03
Paragraphs of tiny text
Dense text renders better than before, but every extra line is another chance for a typo. Print only what a viewer would read.
Reference images: up to four
Reference images let Seedream 5.5 edit your picture or match its style. Here is how many you can add and why.
Why four
Seedream 5.5 charges for every reference image on top of the picture it makes. Up to four, the price stays at 8 credits per image at 1K or 12 at 2K; past that it would cost more than we charge, so the generator stops at four.
Put the main picture first
Upload the image you are editing first, then any style or object references, and refer to them by position: “the person in the first image.”
One reference is often enough
For a straight edit, the photo you are changing is all you need. Add more only when you are combining things or matching a look.
Seedream 5.5 price: credits per run
You pay per image. Every number below comes from the same code that prices the generator.
| Images | 1K | 2K | 1K + reference | 2K + reference |
|---|---|---|---|---|
| 1 | 6 | 10 | 8 | 12 |
| 2 | 12 | 20 | 16 | 24 |
| 3 | 18 | 30 | 24 | 36 |
| 4 | 24 | 40 | 32 | 48 |
credits
How the price works
Credits = images × the price per image. Four 2K images cost 40 credits; four 2K edits with reference images cost 48.
What a plan buys
The Starter plan's 1,500 monthly credits cover about 150 Seedream 5.5 images at 2K, or 250 at 1K.
Failed images are refunded
If an image fails, its credits go back to your balance automatically, even when the other images in the run succeed.
