OpenClaw + Z Image Questions
Can I use Z Image in OpenClaw?
Yes. If RunAPI is configured as a provider in OpenClaw, the same API key handles Z Image requests. Call the endpoint shown on this page.
When should I choose Z Image over other image models?
Z Image is suited to high-volume work and concept exploration where speed and cost matter most. For final selects that need maximum fidelity, compare it with a higher-end image model.
Can Z Image render Chinese and English text in the same image?
Yes. You can mix both languages in the prompt, and the model handles typography for both scripts, which helps with multilingual labels and marketing materials.
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.
