About the Flux 3 Video API

How much does the Flux 3 Video API cost?

Flux 3 Video costs from $0.06 per second of video on Revana (draft: $0.06; fhd: $0.29; hd: $0.17; v2v-draft: $0.12; v2v-fhd: $0.53; v2v-hd: $0.41). You pay in prepaid credits, 100 credits to the dollar, with no subscription or monthly minimum. A generation that fails costs nothing.

How do I call Flux 3 Video from code?

Send POST https://api.revana.si/v1/generations with {"model": "flux-3-video", "input": {...}} and your Revana API key as a Bearer token, poll GET /v1/generations/{id} until it succeeds, then download GET /v1/generations/{id}/content. Every model on Revana takes the same request shape.

What happens if a Flux 3 Video generation fails?

You are charged once, only for the route that delivers. A failed generation costs $0.00.

What can Flux 3 Video do on Revana?

Flux 3 Video supports text to video and image to video, resolutions draft, hd, fhd, durations 5 to 20 seconds and generated audio. A value it does not offer is refused with 422 before anything is charged.
