Use Seedream in OpenClaw.
Seedream is Bytedance's image generation model with strong typography rendering and up to 4K output. OpenClaw agents call it through the same RunAPI key and endpoint used for chat — no extra skills or provider accounts.
Generate a 4K product hero image using Seedream through RunAPI.
Requirements:
- Use the RunAPI text_to_image endpoint.
- Set model to seedream-4.5-text-to-image.
- Read the API key from RUNAPI_API_KEY. Do not hardcode the key.
- Poll the task status endpoint until the task completes.
- Return the generated image URL from the task response.
curl -X POST https://runapi.ai/api/v1/task/text_to_image \
-H "Authorization: Bearer $RUNAPI_API_KEY" \
-H "Content-Type: application/json" \

}'

}
Use Seedream in OpenClaw in three steps
Configure RunAPI
If you already set up RunAPI in OpenClaw for chat, you are done. The same RUNAPI_API_KEY and /v1 endpoint handle image generation. If not, paste the setup prompt from the OpenClaw guide or export the key in your shell.
export RUNAPI_API_KEY=runapi_xxx
Call Seedream
Send a request to the text_to_image endpoint with model set to seedream-4.5-text-to-image. Include a text prompt describing the image. RunAPI returns a task ID immediately.
text_to_image
Get the result
Poll the task status endpoint with the returned task ID. When the status changes to completed, the response includes the generated image URL. RunAPI SDKs handle polling automatically.
task_id: tsk_abc123

What is Seedream on OpenClaw?
Seedream is ByteDance's image model that users describe as offering "unmatched value" with 4K-quality output and 94% text accuracy out of the box. It holds onto structure in complex prompts -- multiple objects, specific spatial relationships, detailed typography -- without losing coherence. OpenClaw agents call it through the RunAPI text_to_image endpoint with the same API key used for chat.
Seedream use cases
E-commerce product catalogs
Generate product lifestyle shots with accurate labels and pricing text baked into the image, ready for catalog pages without post-production text overlays.
Typography-heavy poster and event design
Create event posters, signage, and billboards where the text content is specified in the prompt and rendered at 94% accuracy or better.
Batch generation for brand campaigns
Generate consistent character or product series across dozens of images, maintaining the same brand ambassador appearance and house style throughout.
Seedream + OpenClaw questions
Yes. Configure RunAPI as an OpenAI-compatible provider in OpenClaw, then call the text_to_image endpoint with model set to seedream-4.5-text-to-image. The same API key handles both chat and image generation.
No. The same RUNAPI_API_KEY you configured for chat also calls Seedream and every other image model in the RunAPI catalog. One key, one billing account.
Async. RunAPI returns a task ID on the first call. Poll the task status endpoint until the status is completed, then retrieve the image URL from the response. SDKs and the CLI handle polling automatically.
Seedream uses per-generation pricing. Check the RunAPI pricing page for current rates. Failed generations are not charged.
Yes. Seedream handles consistent character generation well when you describe the character in detail across prompts. It maintains facial features, body proportions, and clothing style across a batch of images, making it suitable for creating brand ambassador series or product model sequences.
Yes. Seedream produces photorealistic product shots with accurate material textures, lighting, and spatial relationships. It is particularly strong at lifestyle shots where products appear in realistic settings with proper shadows and reflections.
Seedream 4.5 is the full model with 4K output and the highest fidelity. Seedream 5 Lite is a faster, cheaper variant optimized for speed at standard resolution. Both share the same text_to_image endpoint -- set the model slug to seedream-5-lite-text-to-image for faster generation or seedream-4.5-text-to-image for maximum quality.
