Seedream 4.5 AI Generator
Generated on PixelDojo with Seedream 4.5. Produced by PixelDojo's generation pipeline.
Seedream 4.5 costs 1 credit per image and took about 34 seconds to place a reference character into a new scene on August 26, 2026. We sent it a character reference sheet and an instruction to put that exact woman on a bicycle in a rainy city crosswalk, and it kept her face, glasses, hair, and outfit while building the new setting around her. This page covers what that edit looked like, what a four-image request costs, and when to pay more for Seedream 5 instead.

Seedream 4.5
What we found placing a character into a scene
What we ran
We sent a four-panel character reference sheet as image_urls with the instruction to place that exact woman on a bicycle crossing a rainy city crosswalk at dusk, neon shop signs reflecting in puddles, cinematic wide shot, keeping her face, glasses, red curly hair, denim jacket and yellow shirt identical.
What we saw in the output
The face, round glasses, red curly hair, denim jacket, and yellow shirt all carried over correctly. She is riding a bicycle through a crosswalk at dusk with red and green neon signage reflected in the wet street, matching the prompt closely.
It picked a wide frame on its own
We left image_size at its default, auto_2K, and did not ask for a specific aspect ratio. The output came back in a wide, roughly 21:9 frame rather than the square shape of the reference sheet, which reads as the model leaning into the prompt's own words, cinematic wide shot, rather than matching the source image's proportions.
1 to 4 images per request, flat price
The count field takes 1 to 4, and the price is 1 credit per image regardless of count or whether reference images are attached, so a four-image sweep is 4 credits in one call.
Up to 14 reference images
Send up to 14 reference image URLs alongside a prompt for multi-image composition, at no change to the per-image credit price.
One reference image, one scene-placement instruction: 1 credit, about 34 seconds, on August 26, 2026.
Why Choose Pixel Dojo for Seedream 4.5
Professional-quality results with cutting-edge AI technology
1 credit per image
Flat, regardless of resolution preset or how many reference images you attach. Four images in one call is 4 credits.
About 34 seconds, measured
Timed from request to finished file on August 26, 2026, for a single-image edit with a reference character sheet attached.
Identity held up across the scene change
Face, glasses, hair color and style, and both clothing items all matched the reference sheet in the new setting, with no retries needed.
How It Works
How we ran it, so you can repeat it:
Send the reference and the instruction together
We passed our character sheet as image_urls alongside a prompt naming every detail to preserve: face, glasses, hair, jacket, shirt.
Name what has to change and what has to stay
Our prompt described the new scene, the bicycle, the crosswalk, the neon, while explicitly listing the identity details to keep identical.
Run it in the app or over the API

Common Questions
Everything you need to know about Seedream 4.5
What does Seedream 4.5 cost?
1 credit per image. A request can return 1 to 4 images, priced at 1 credit each, so a four-image call is 4 credits. Sending reference images does not add to the price.
How fast is Seedream 4.5?
About 34 seconds in our August 26, 2026 run, measured from submission to finished file, for a single edit with one reference image attached. Real turnaround moves with queue load.
Can it keep a character consistent across scenes?
In our test, yes. It carried over the face, glasses, red curly hair, denim jacket, and yellow shirt from a reference sheet into a new bicycle-and-crosswalk scene without us needing to retry or adjust the prompt.
How many reference images can I send?
Up to 14 in one request, passed as image_urls, for multi-image composition.
How do I call it from the API?
POST to /api/v1/models/seedream-4/run with your API key, a prompt, and optionally image_urls for an edit. Same key and request shape as every other model in the catalog.
Is Seedream 5 worth the extra credits over 4.5?
Seedream 5 costs 1.25 credits at its 1K tier against 4.5's flat 1 credit, and on our matching scene-placement test it produced a tighter, more shallow-depth-of-field crop with the same identity held intact. 4.5 is the cheaper way to get a wide, fully composed scene; 5 leans toward a closer, more filmic result.
