FLUX 3 video API adds qhd (2K) and uhd (4K) resolutions, from $0.40/s

resolution on POST /v1/flux-3-video now takes qhd and uhd alongside hd and fhd, so a 2K or 4K clip comes back from a single request instead of a generation followed by a separate upscale call.

Key Features

  • qhd — 2560 × 1440 at 16:9
  • uhd — 3840 × 2176 at 16:9
  • Same generation, larger canvas — every class above hd runs the same generation and differs only in the canvas the video upsampler renders, so the shot does not change with the resolution you pick
  • Available on draft_enhance too — commit a draft straight to 2K or 4K. Drafts themselves still render at hd

Pricing

Per second of output, in addition to the existing hd and fhd rates:

| Mode | qhd | uhd | | - | - | - | | Text to Video (t2v) | $0.40/s | $0.80/s | | Image to Video (i2v) | $0.40/s | $0.80/s | | Video Continuation (v2v) | $0.65/s | $0.95/s |

Endpoint

POST /v1/flux-3-video

Delivered dimensions for every aspect ratio are in the FLUX 3 video documentation, and full rates on the pricing page.
