Veo 3.1 Fast — AI video generator
Veo 3.1 quality at lower latency, for iterating on a shot
Veo 3.1 Fast is the low-latency variant of Google's flagship. It takes the same prompts, the same clip lengths and the same audio generation, and returns them sooner — the version to work in while a shot is still changing, before the final render.
What Veo 3.1 Fast is good at
- Noticeably shorter turnaround than standard Veo 3.1
- Same synchronized audio generation
- Same resolutions and clip lengths, so a draft maps 1:1 onto the final
- Optional reference image as the first frame
What people use it for
- Iterating on prompt wording before a final Veo 3.1 pass
- Client review rounds where turnaround beats the last few percent of quality
