Hermes Agent + Runway Questions
Can I use Runway video generation in Hermes Agent?
Yes. With RunAPI configured as a provider in Hermes Agent, the agent can call the Runway endpoints shown on this page using your RunAPI API key.
Can Hermes Agent generate the first frame with another model?
Yes. Hermes Agent can create a starting image with an image model, then pass that image URL to Runway as the first frame.
Can Hermes Agent choose between generating and restyling video?
Yes. The Runway line covers new video generation and editing of existing footage. Hermes Agent picks the endpoint and model version per request.
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.
