name: seedream-image-generation description: Image generation via Volcengine Seedream API. Use this when you need to perform Text-to-Image (T2I), Image-to-Image (I2I),使用豆包生图 or general visual creative tasks based on textual or visual inputs. metadata: { "openclaw": { "requires": { "env": ["ARK_API_KEY"] }, "primaryEnv": "ARK_API_KEY" } }

Seedream Image Generation Skill

This skill provides methods for calling the Volcengine Ark large model service platform's image generation models (Seedream).

Select Environment

The script provides implementations for both Python and JavaScript:

• If your runtime is primarily Node.js/TypeScript or a web module, use seedream.js.
• If your runtime involves complex data analysis, batch scheduling, or is purely Python, use seedream.py.

Supported Model Parameters (Model ID/Endpoint ID)

When invoking, the model parameter needs to be the deployment Endpoint ID from the Ark console (e.g., ep-202X...), which must be backed by one of the following foundational image generation models:

• doubao-seedream-5-0-260128
• doubao-seedream-4-5-251128
• doubao-seedream-4-0-250828

Script Parameters

You must pass specific parameters to control the image generation. The available parameters are:

• model (string, optional): Endpoint ID corresponding to the model. Defaults to doubao-seedream-5-0-260128.
• prompt (string, required): Text description used to generate the image.
• image (string | list of strings, optional): Local image path or image path list used for image-to-image generation. The scripts will read the local file, convert it to base64, and send it as the request image field.
• watermark (boolean, optional): Whether to add a Volcengine AI watermark. Unprovided value assumes false.
• optimize_prompt_options (object, optional): Configure automatic prompt optimization options. Format: JSON object. E.g., {"mode": "standard"}.
• tools (list of objects, optional): Capabilities options for the model, formatted as JSON. Example: [{"type": "web_search"}].
• output_format (string, optional): The output image format. Options include png, jpeg.
• sequential_image_generation (string, optional): Sequential image generation strategy (e.g., "auto").
• download_dir (string, optional): Local directory to save the generated images. If not provided, images will not be downloaded locally, and only the API response will be returned.

Usage Examples

Python Example:

cd <current_skill_dir>
python3 seedream.py \
  --prompt "A cute orange cat laying under the sun" \
  --model "ep-xxxxx..." \
  --size "1024x1024" \
  --watermark "false" \
  --output_format "png"

Node.js Example:

cd <current_skill_dir>
node seedream.js \
  --prompt "A cute orange cat laying under the sun" \
  --model "ep-xxxxx..." \
  --size "1024x1024" \
  --watermark "false" \
  --output_format "png"

Image-to-Image Example (Python):

cd <current_skill_dir>
python3 seedream.py \
  --prompt "Turn this product photo into a clean white-background ecommerce image" \
  --image "/path/to/source.png" \
  --model "ep-xxxxx..."

Advanced Example with Tools and Optimization (Python):

cd <current_skill_dir>
python3 seedream.py \
  --prompt "A futuristic cityscape" \
  --model "ep-xxxxx..." \
  --optimize_prompt_options '{"mode": "standard"}' \
  --tools '[{"type": "web_search"}]'
