Calling FLUX 3

POST /v1/videos
import os
from infro import Infro

client = Infro(api_key=os.environ["INFRO_API_KEY"])

job = client.videos.create(
    model="bfl/flux-3",

What this modality supports

  • Async jobs
  • Signed webhooks
  • Lip sync & avatars
  • Permanent output URLs

Text-to-video, image-to-video, lip sync, and talking avatars as managed async jobs. Submit, get a job id, receive a signed webhook when the render lands. Finished media is re-hosted on our CDN under your account, so output links don't expire underneath you.
