Seedream Image Generation

Generate and edit AI images through AceDataCloud's Seedream (ByteDance) API.

Authentication

export ACEDATACLOUD_API_TOKEN="your-token-here"

Quick Start

curl -X POST https://api.acedata.cloud/seedream/images \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a cyberpunk cat wearing VR goggles in a neon city", "model": "seedream-3.0"}'

Models

Model	Resolution	Speed	Best For
`seedream-2.0`	Standard	Fast	Quick drafts
`seedream-2.1`	Standard	Fast	Improved quality over 2.0
`seedream-3.0`	Up to 2048×2048	Standard	High-quality generation (default)
`seedream-3.0-turbo`	Up to 2048×2048	Faster	Speed-optimized with near-3.0 quality

Workflows

1. Text-to-Image

POST /seedream/images
{
  "prompt": "a serene Japanese garden with cherry blossoms and a red bridge",
  "model": "seedream-3.0",
  "width": 1024,
  "height": 1024
}

2. Image Editing (Inpainting / Outpainting)

Edit regions of an existing image using a mask.

POST /seedream/images/edit
{
  "prompt": "replace with a golden sunset sky",
  "image_url": "https://example.com/photo.jpg",
  "mask_url": "https://example.com/mask.png",
  "model": "seedream-3.0"
}

Parameters

Generation

Parameter	Values	Description
`model`	`"seedream-2.0"`, `"seedream-2.1"`, `"seedream-3.0"`, `"seedream-3.0-turbo"`	Model to use
`width`	512 – 2048	Image width in pixels
`height`	512 – 2048	Image height in pixels
`seed`	integer	Seed for reproducible results

Editing

Parameter	Required	Description
`image_url`	Yes	URL of the source image to edit
`mask_url`	Yes	URL of the binary mask (white = edit region)
`prompt`	Yes	Describe what to place in the masked area

Gotchas

Maximum resolution is 2048×2048 — exceed this and requests fail
Mask images must be binary (black/white) with the same dimensions as the source image
seedream-3.0-turbo offers a good speed/quality trade-off for iterative workflows
Results return a direct image URL — no task polling needed for generation
Editing always requires both image_url and mask_url
