You have access to RunAPI task tools for Imagen 4.

Available Imagen 4 models:
- imagen-4: Balanced quality and speed; recommended default
  endpoints: /api/v1/imagen_4/text_to_image
  request fields: model, prompt, aspect_ratio
- imagen-4-fast: ~2.7s generation; rapid iteration and drafts
  endpoints: /api/v1/imagen_4/text_to_image
  request fields: model, prompt, aspect_ratio
- imagen-4-pro-remix-image: Prompt-guided remix variant; source images to styled output
  endpoints: /api/v1/imagen_4/remix_image
  request fields: model, prompt, source_image_urls
- imagen-4-ultra: Maximum photorealism and prompt adherence; brand/marketing grade

Use the model ID and endpoint that match the user's request.
Example prompt: Generate a product hero image of a matte-black water bottle on a beige stone surface, soft side light.
/api/v1/imagen_4/text_to_image: Submit the task, poll for its status, then verify the completed output. POST /api/v1/imagen_4/text_to_image and save the returned Task id.
GET /api/v1/imagen_4/text_to_image/<task-id> until status is completed or failed.
Verify the completed response contains the endpoint-specific output documented in the API reference.
/api/v1/imagen_4/remix_image: Submit the task, poll for its status, then verify the completed output. POST /api/v1/imagen_4/remix_image and save the returned Task id.
GET /api/v1/imagen_4/remix_image/<task-id> until status is completed or failed.

How it works

Get Started in 3 Steps

  1. Choose a model ID

    Select a public catalog model ID and review its endpoint and current starting price.

  2. Configure RunAPI

    Set RUNAPI_API_KEY before making the endpoint request.

  3. Verify the result

    For asynchronous endpoints, poll the same endpoint until the Task reaches a terminal status.

What to Build with OpenClaw + Imagen 4

  • Rapid prototyping at scale

    Use a faster tier for quick concept exploration, then switch to a higher-quality tier once you have chosen a direction.

  • UI and label design with readable text

    Generate interface mockups, product labels, and signage where the embedded text renders cleanly and follows the prompt.

  • Photorealistic textures and materials

    Create photorealistic material textures, travel postcards, and outdoor photography scenes with accurate lighting and surface detail.

Why Use Imagen 4 Through RunAPI + OpenClaw

  • 4 variants, one API key

    Use one RunAPI connection to choose among the live model variants without changing your integration.

  • Clear usage pricing

    See current catalog pricing before you send a request, with no subscription or minimum spend required.

  • Automatic task workflows

    Submit, poll, and collect asynchronous results through a consistent task workflow without writing manual polling code.

OpenClaw + Imagen 4 Questions

Can I use Imagen 4 in OpenClaw?

Yes. OpenClaw agents call Imagen 4 through the RunAPI endpoint shown on this page, with the same RunAPI API key used for chat. No extra skills or plugins are required.

How do the Imagen 4 tiers differ?

The faster tier suits drafts and concept exploration, the standard tier suits production work, and the highest tier produces the most detail for hero or print assets. All tiers use the same prompt format.

How strict are Imagen 4's content filters?

Imagen 4 filters can flag some harmless prompts, especially around people and brand imagery. If a generation is rejected, rephrase the prompt to state the intended context more clearly.

Which model ID should I use?

Choose a public model ID from the version table. Each ID exposes the endpoints shown for that version.

Does this guide configure a chat model?

No. This Model Line uses the endpoint workflow shown here and is not presented as an agent chat model.
