Seedream 5.0 Pro API
Seedream 5.0 Pro creates design-focused images with readable layouts, multilingual text, and detailed materials. Use its Images API through APINEED for 1K or 2K output.
ByteDance released Pro on July 8, 2026, with an emphasis on structured design and localized edits. APINEED returns generated images synchronously in data[]. This playground requests one result at a time; it does not offer streaming or automatic batches. The gallery below contains a real production text-to-image test, not a quality guarantee for other prompts.
Playground
Generate with Seedream 5.0 Pro, review the output, and use the same request shape in your application.

}Providers
ByteDance documents the broader model capability. APINEED separately defines the model ID, endpoint, parameter whitelist, authentication, and billing behavior shown on this page.
Image pricing
Output tiers and reference-image charges. The starting price is not a flat price for every request.
| Billing item | Baseline price | APINEED price |
|---|---|---|
| Output up to 2.4 million pixels | $0.044776 | $0.040299 |
| Output above 2.4 million pixels | $0.089552 | $0.080597 |
| First reference image | $0.000000 | $0.000000 |
| Each additional reference image (2–10) | $0.002985 | $0.002687 |
Availability
APINEED monitors Seedream 5.0 Pro API availability. Applications should preserve request and task IDs and handle upstream failures explicitly.
No model-specific availability history is published yet. A successful request is not an uptime guarantee.
Typography and layout
ByteDance highlights multilingual typography and structured layouts. Specify exact wording, reading order, spacing, and the intended publishing surface. [1]
Reference-guided changes
The documented image field accepts visual references for editing. State what should change and what should stay; reference editing has not yet been re-tested in this frontend release. [2][3]
Output-aware billing
Pro has two output-pixel tiers plus additional-reference charges. A 2K request is not a promise of the lower price; the completed image determines its tier. [3]
Direct the composition
Write the copy verbatim. Put exact labels and headlines in quotes, then describe their position and relative visual weight.
Be specific about edits. Identify the object or region to change and name any background, identity, or layout that must remain unchanged.
Seedream 5.0 Pro API Gallery
Quick Start
Call Seedream 5.0 Pro with the verified APINEED endpoint and model-specific request shape.
Create an API key
Store your APINEED key server-side as API_NEED_API_KEY.
export API_NEED_API_KEY=sk-apineed-v1-...Send the request
Use seedream-5.0-pro with POST /v1/images/generations.
curl https://apineed.com/v1/images/generations \
-H "Authorization: Bearer $API_NEED_API_KEY" \
-H "Content-Type: application/json" \
-d '{

}'Parse the image
Read every item in data[] and handle either its url or b64_json value.
const images = response.data.map((item) => item.url ?? item.b64_json);Seedream 5.0 Pro API Endpoint
Create a single image through the Images API and read the returned data array. This request does not create a video task.
/v1/images/generations- Authorization
- Bearer $API_NEED_API_KEY
- Content-Type
- application/json
- HTTP-Referer
- optional - your site URL, for rankings
- Model
- seedream-5.0-pro
Parameters
These controls follow APINEED's current DTO and adapter behavior. Unsupported upstream-only fields are intentionally omitted.
| Name | Type | Values | Description |
|---|---|---|---|
model | string | Required | Use seedream-5.0-pro. |
prompt | string | Required | Describe the desired image or the edit to make. |
image | string | string[] | Optional | Reference image URL or up to 10 reference URLs. Omit for text-only generation; the playground uploads your selected files first. |
size | string | Optional | 1K or 2K. The playground defaults to 2K; actual dimensions and pixel count depend on the generated composition. |
n | integer | 1 | This integration requests one output per call. Multi-image batches are not exposed. |
response_format | string | Optional | The playground requests url and displays data[].url. |
output_format | string | Optional | png or jpeg; the Pro example uses png. |
watermark | boolean | Optional | Watermark preference. Explicit false is forwarded, not silently removed. |
Seedream 5.0 Pro API questions
Practical answers for choosing, integrating, pricing, and operating the Seedream 5.0 Pro API on APINEED.
When was Seedream 5.0 Pro released?
ByteDance announced Seedream 5.0 Pro on July 8, 2026. APINEED uses this release date in the model directory instead of treating a missing date as an old model. [1]
Why does Pro show a starting price instead of a flat rate?
The configured output charge is $0.040299 up to 2.4 million pixels and $0.080597 above that threshold. Additional reference images can increase the total; the first reference is included. [3]
Does choosing 2K always use the cheaper output tier?
No. Our successful 2K test returned a 2496 × 1664 PNG and settled at approximately $0.080598 after quota rounding. Billing follows the returned image, not the label alone. [3]
How do I submit reference images to Pro?
Use image, not images, with a URL or an array of up to ten URLs. Image to Image uploads files before calling the same generation endpoint. This field is documented; this release has only re-verified real text-to-image generation. [2][3]
Do Pro requests require task polling?
The Pro image call waits for generation and returns data containing image URLs. It is not the video task workflow, so do not try to poll a video task ID afterward. [3]
Can I reuse GPT Image quality and compression settings?
This Pro form intentionally omits GPT-specific quality and output_compression controls. Only the fields listed on this page are sent; use size, output_format, and watermark for the available output preferences. [2][3]
