Seedream 4.5 AI Image Generator
Seedream 4.5 is ByteDance's photoreal text-to-image model, sitting between Seedream 4.0 and the 5.0 line. It takes a prompt, an aspect ratio and a quality setting, and returns a single image.
From 21:9 through 9:16, chosen up front rather than cropped afterwards.
Signage and lettering in a scene come back legible more often than they used to.
One flat rate per image, whichever ratio and quality you pick.

Three images Seedream 4.5 made here
Generated with Seedream 4.5 on this site on 2026-08-04, unretouched, at the basic quality setting. They were picked to show the three things this model is asked for most: skin and material texture, legible lettering inside a scene, and a flat-lay where every small object has to stay in focus.

What is Seedream 4.5?
Seedream 4.5 is a text-to-image model in ByteDance's Seedream family, positioned above 4.0 and below the 5.0 Lite and 5.0 Pro tiers. It takes three things: a written prompt, one of eight aspect ratios, and a quality setting of basic or high. There is no separate resolution ladder and no image count — one request returns one image.
What it is good at is the photoreal end of the range: material surfaces, skin, and the small print inside a scene. Text rendering is the part most worth knowing about, because it is where image models have historically failed in a way that is obvious to anyone looking; asking 4.5 for a sign, a label or a book spine returns something readable far more often than the generation before it did.
It is not an editor. Handing it an existing image to modify is a different model id on both shelves, and that path is not wired here.

What an image costs
One flat rate per generated image, independent of the aspect ratio you choose.
Between 4.0 and the 5.0 line
The mid tier of the Seedream family, and the cheapest one that does photoreal well.
Three inputs, no more
Prompt, aspect ratio, quality. There is no seed, no batch and no resolution field.
Text to image only
Editing an existing image is a separate model and is not available on this page.
When 4.5 is the right pick
Pick 4.5 when the image has to look photographed and has to contain writing. That combination is narrower than it sounds and it is exactly where the cheaper tiers give up: Seedream 4.0 will produce a handsome image and turn the sign in the background into ornamental squiggles. Go up to 5.0 Pro when the subject is a person in motion, or when you need the extra fidelity enough to pay twice as much for the high quality setting. Stay on 4.0 when the picture is decorative and nobody will read anything inside it. The prompt transfers between all three, so testing down the ladder costs almost nothing. When the writing is the whole picture rather than a sign inside it — a headline, a set of numbered steps, a caption under every panel — [Qwen Image 3](/image/qwen-image-3) is built for that specific job.
Signs, labels and packaging
Anything where the words in the frame are part of the point rather than set dressing.
Material and surface
Rust, condensation, worn leather, wet rope — texture is where photoreal is won or lost.
Fixed ratio from the start
Generating at 21:9 or 9:16 directly beats cropping a square down to it afterwards.
Feature overview
What the model accepts, and what it deliberately does not.
Text to image
One prompt in, one image out, with no source material required.
Eight aspect ratios
1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2 and 21:9.
Basic and high quality
Two settings rather than a resolution ladder; basic is what this page generates by default.
In-scene typography
Words asked for inside the image come back legible more reliably than on 4.0.

From prompt to image
Four steps, and the third is the one that changes the result most.
Pick the ratio first
Decide the shape before you write, because framing changes what belongs in the prompt.
Describe the light
Photoreal models respond to stated lighting far more than to adjectives like beautiful or stunning.
Quote any text exactly
Put the words you want rendered in the prompt verbatim. Paraphrasing them is how they come back wrong.
Run it twice
Two images at 25 credits each is a cheaper way to find the shot than rewriting the prompt blind.
What people generate with it
Jobs where the image has to survive being looked at closely.
Product and packaging shots
Labels, bottles and boxes where the printed text has to read correctly.
Editorial photography
People and places lit like a magazine shoot rather than an illustration.
Storefronts and signage
Scenes built around lettering — shop fronts, menus, street signs.
Flat lays and still life
Overhead arrangements where every object has to hold its own detail.

Model credit guide
What each model costs in credits
You're only charged for successful generations. The exact estimate in the generator varies by model, length, resolution, audio, and number of images.
| Type | Model | Credit cost |
|---|---|---|
| GPT Image 2 | Text to image and description-based edits. 1K ≈ 20 credits, 2K ≈ 90, 4K ≈ 160. | |
| Nano Banana 2 | Generate or edit from up to 14 reference photos. Same 20 / 40 / 80 ladder by resolution. | |
| Nano Banana 2 Lite | The free tier's editor. Lightest cost per edit on the site. | |
| Seedream 5 Lite | Fast drafts. Priced at the 1K tier for iteration passes. | |
| Qwen Image 3 | Legible text and page layout rather than photoreal. Priced by resolution. |
Seedream 4.5 FAQ
Common questions about the mid tier of the Seedream family.
4.5 is the newer generation and is noticeably better at rendering text inside an image. 4.0 takes an image size and a 1K/2K/4K resolution instead of a quality setting, and costs a little less.
About 25 credits, flat, whichever aspect ratio you choose. Seedream 4.0 is about 8 and Seedream 5.0 Pro about 11 at its basic setting.
Not on this page. Seedream editing is a separate model id on the provider, and only the text-to-image path is wired here.
They are the two settings the API exposes. This page generates at basic; on the 5.0 Pro tier the same switch is also a price difference, which is why it is sent explicitly rather than left to a default.
Often, and far more often than earlier models, but not guaranteed. Quote the text verbatim and keep it short — long paragraphs inside an image are still unreliable on every model.
Credits are returned automatically, unless the request broke the content policy.
4.5 is the middle child on purpose: flat 25 credits, more detail than 4.0, more predictable than the 5.0 line. It is the safe default for batch work where you want one engine's consistent look across fifty images.
