For asynchronous endpoints, poll the same endpoint until the Task reaches a terminal status.
What to Build with Hermes Agent + Luma
-
Concept reels and animated stills
Turn rough footage into stylized motion pieces, with Hermes Agent generating a base clip first and passing it to Luma for re-rendering.
-
Seasonal and brand content repurposing
Restyle existing video to match seasonal campaigns, new brand guidelines, or different market aesthetics without reshooting.
-
Abstract and surreal visual content
Apply surreal, painterly, or abstract transformations to source footage for creative projects and music visualizations.
Why Use Luma Through RunAPI + Hermes Agent
-
1 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.
Hermes Agent + Luma Questions
Does Luma generate audio?
No. Luma modifies the visual track only. Use an audio model through RunAPI to add sound after the visual transformation.
Can Hermes Agent chain Luma with video generation models?
Yes. A Hermes Agent workflow can generate a clip with another video model, then pass the output URL to Luma for re-rendering, all through the same RunAPI provider.
Can Luma keep characters consistent while modifying video?
Luma preserves composition and character positions, but fine facial details can drift under heavy style changes. Keep style changes moderate when character consistency matters.
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.
