Seedream 5.0 Pro & Flash AI Image Generator
Seedream 5.0 is a family of image generation models from ByteDance
What is Seedream 5.0?
Seedream 5.0 is a family of image generation models from ByteDance. On blubiu it comes in two tiers, Pro and Flash; both render at 1K or 2K, from a text prompt or from reference images (up to 4 per run in the blubiu generator), for a fixed price per image.

What Seedream 5.0 is good at
- +Cheap 2K images in bulk: Flash costs the same at 1K and 2K, so even drafts can be full 2K and a good draft is already a finished image.
- +Combining several references: pass a character, a product and a background, and say what each is for, such as image 1 is the character and image 2 is the room.
- +Restyling an existing image: pass it as the reference, say what must stay, and describe the new look, such as watercolor, winter or night.
- +Clothing and material detail: in our AI outfit changer side-by-side test, Pro got every outfit detail right.
- +A second take on a prompt: run it here and on another model in the image generator AI, then keep the version you prefer.
When not to use it
- −You need 4K. Seedream 5.0 stops at 2K; GPT Image and Nano Banana go up to 4K. See GPT Image →
- −You are editing a photo of a real person and need them to stay recognizable. ByteDance's content review may reject it. See GPT Image →
- −You need a multi-reference result quickly. Pro took about four minutes per image in our outfit test with three references; GPT Image 2.5 Flare is the default there.
- −The image needs a lot of small readable text, like a poster with a title and labels. Our text-heavy character reference sheet renders at 4K because small text needs it, and Seedream 5.0 tops out at 2K. See GPT Image →

How to prompt Seedream 5.0
Describe materials and light
At 2K, surface detail is visible, so specify materials (matte clay, glossy plastic, fur) and the light source; vague prompts produce generic textures. Name one main light, such as window light from the left, soft overcast or a neon rim light, rather than a list of moods.
Label every reference
With several references, say which one carries the subject and which the style or background ("image 1 is the character, image 2 is the room"). Unlabelled references get mixed unpredictably.
Draft on Flash, finish on Pro
Settle the composition on Flash, then rerun the keeper on Pro at 2K if you want the higher tier. Keep the prompt and the references identical between the two runs, so the only thing that changes is the tier and you can judge the difference fairly.
For restyles, say what stays
When you pass an image to restyle, list what must survive (the pose, the layout, the product's colors) before the new look (watercolor, winter, night). Without that list, a restyle can drift into a new picture.
Use a character sheet as the identity reference
For a recurring character, pass one consistent character sheet instead of a single photo: three face angles and a full turnaround give the model a matching view when the head turns or the character faces away.
Pick the ratio for the video it will become
A still you plan to animate in image to video should already be 16:9 or 9:16, because the clip starts from that exact frame; cropping afterwards cuts the edges of the composition.
Seedream 5.0 FAQ
Is Seedream the same as Dreamina (Jimeng)?
No. Seedream is ByteDance's image model family; Dreamina/Jimeng is a ByteDance app. On blubiu you call the Seedream 5.0 models directly and pay with blubiu credits — you are not using the Jimeng app or its account.
What's the difference between Pro and Flash?
Both take text and reference images and render at 1K or 2K. Pro is the higher tier and costs more at 2K; Flash costs the same at 1K and 2K. In our outfit test, Pro got every clothing detail right but took about four minutes per image. A practical split: settle the composition on Flash, then rerun the keeper on Pro, or run the same prompt on both and keep the one you prefer.
Which resolutions are available?
1K and 2K. When Seedream 5.0 is selected, the generator only offers those two sizes. For 4K, for example for print or a large banner, switch to GPT Image or Nano Banana in the image generator AI.
How is it priced?
A fixed number of credits per image for each tier and resolution; see the table above. Flash costs the same at 1K and 2K, Pro costs more at 2K, and once you sign in the Generate button shows the exact price for your account. Failed generations are refunded.
Can I try it for free?
Yes. The Free plan includes monthly credits you can spend on either tier, and the Generate button shows the price before you confirm. Plans and credit packs are on the pricing page.
Which blubiu tools use it?
The image generator AI, where you pick Pro or Flash from the model list, and the AI outfit changer, where Seedream 5.0 Pro is one of three models next to GPT Image 2.5 Flare and Nano Banana Pro.
How long does one image take?
It depends on the tier and the job, and we have timed one case: Pro took about four minutes per image in our outfit test with three references. The job runs on our servers and the result is saved to your library.
Why was my request rejected?
ByteDance's content review may reject some requests, such as edits of photos of real people. A rejected run is refunded automatically; for real-person edits, try GPT Image, and only upload people who have agreed.
Can I animate an image I made with it?
Yes. Use it as the first frame in image to video and describe only the motion, since the picture itself comes from the frame; Seedance 2.0, ByteDance's video model, is one of the models there. Generate the still in the video's ratio first.
Can I use the images commercially?
The images you generate are yours to use. Make sure the references you upload are yours to use too, and note that ByteDance's content policy applies. Check any text or logos in the result before it goes into an ad.
