About Seedream 5.0 Pro

Generate text-rich images or make precise single-reference edits with ByteDance Seedream 5.0 Pro at 1K, 1.5K, or 2K.

Why choose Seedream 5.0 Pro?

Seedream 5.0 Pro is ByteDance Seed's multimodal image generation and editing model. According to ByteDance Seed, it turns data, concepts, and dense text into professional layouts, renders more than ten common languages, reproduces realistic lighting, materials, and skin textures, and supports precise regional editing grounded in spatial understanding.

In Wizzx, one workflow covers generation and editing: leave the reference area empty to create an image from the prompt, or add one reference image to edit it.

Wizzx controlCurrent behavior
PromptRequired, up to 4,000 characters
Reference imageOptional, one JPEG, PNG, or WebP image; not charged
Aspect ratioAuto (default), 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, 2:1, 1:2, 21:9
Resolution1K (default), 1.5K, or 2K
Output formatJPEG (default) or PNG

Suitable workflows

  • Posters, menus, infographics, and UI mockups where legible text and structured layout matter.
  • Multilingual creative where the same template must render several scripts.
  • Realistic portraits and product scenes with natural lighting and materials.
  • Targeted edits to one source image, such as swapping clothing, colors, or materials while keeping the rest intact.

Prompting approach

Describe the subject, layout, style, and any exact text in quotes. For dense layouts, list the sections or data points you want and their order. For edits, name the region to change, what it should become, and what must stay the same. Start at 1K or 1.5K to iterate, then move to 2K for the final image.

Wizzx scope

Wizzx generates one image per request and accepts at most one reference image. Resolution sets the per-image price, and 1.5K costs the same as 1K; aspect ratio, output format, and the reference image do not change it. The live credit amount shown on the page comes from the backend catalog. Generation is slower than lighter image models, so allow extra time before the result appears.

ByteDance Seed also describes multi-image fusion, layer separation, and batch output for Seedream 5.0 Pro. Wizzx does not currently expose multiple references, n, exact pixel sizes, or watermark controls for this model.

Integrate the Seedream 5.0 Pro API

Every request is asynchronous: submit the task, keep the task ID, then poll for the result. The body below uses the model's default settings.

  1. 1

    Get a Seedream 5.0 Pro API key

    Sign in and create a key in the dashboard. Set WIZZX_API_KEY in your server environment; never expose it in browser code.

  2. 2

    Submit a task

    Send a POST request to the model endpoint. A successful submission returns data.task_id; keep that ID before polling. Submission is not generation completion.

  3. 3

    Retrieve the result

    Replace YOUR_TASK_ID with the returned ID and query /api/v1/task/status. Wait for SUCCEEDED and read the output URLs. Stop on FAILED or REVIEW_REQUIRED; do not automatically resubmit an uncertain task.
