Hermes Agent + Z Image Questions
Can I use Z Image in Hermes Agent?
Yes. If RunAPI is configured as a provider in Hermes Agent, 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.
Does Z Image support custom LoRA adapters through RunAPI?
No. The RunAPI endpoint serves the base model without custom adapters. If you need fine-tuned output, run the open weights locally with your own LoRA.
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.
