What Veo 3.1 Fast is
Veo 3.1 Fast is Google's video model, reached through Replicate, and it generates picture and speech together in a single pass from a reference image plus a prompt. We deliberately run the Fast variant rather than standard Veo 3.1: standard is roughly two and a half times the wholesale rate for the same clip, and that gap would land on your credit balance rather than ours. Because the Fast rate is flat per second with no resolution multiplier, 720p and 1080p cost the same number of credits as each other.
Where Veo 3.1 Fast fits, and where it does not
Good for
- Hooks and openers, where 8 seconds is the whole ad
- Renders that need speech and picture from one pass, with no separate voice step
- Single reference image driving a scripted scene
Limits
- Hard ceiling of 8 seconds per call, the shortest of the models where you pick the clip length
- Needs a reference image, so there is no prompt-only path
- Tops out at 1080p, with no 4K tier
Choose Veo 3.1 Fast if the ad lives or dies in its first few seconds and you want picture and audio out of a single render.

Veo 3.1 Fast: frequently asked questions
How much does Veo 3.1 Fast cost per render?
Between 120 and 245 credits, depending on clip length. Priced lengths are 4s, 6s and 8s, and 720p and 1080p carry the same credit cost as each other because the underlying rate is flat per second with no resolution multiplier. The full table is on this page.
What is the maximum length of a Veo 3.1 clip?
8 seconds in one call. That is the model's own native limit, not a cap we impose, and it is the shortest ceiling among the models where you choose the length. Longer ads are built by generating several clips and joining them.
Does Veo 3.1 generate audio?
Yes. Audio is native: speech and ambience come out of the same pass as the picture, so there is no separate voiceover step to run or pay for.
Veo 3.1 or Sora 2?
Veo caps at 8 seconds and needs a reference image. Sora 2 runs to 12 seconds and, like Sora 2 Pro, will generate from a written prompt alone, but OpenAI has announced an end date for it, which we show on its own page. If you need one unbroken clip longer than 8 seconds from a model with no announced end date, Happy Horse 1.1, Kling 3.0 and Seedance 2.0 all render up to 15 seconds.
Can I use Veo 3.1 Fast on the free trial?
Veo 3.1 Fast runs during the free 3-day trial. Trial renders are capped at 250 credits each, and Veo 3.1 Fast starts at 120 credits. Inside that ceiling the trial covers 4s at 720p and 1080p for 120 credits, 6s at 720p and 1080p for 180 credits and 8s at 720p and 1080p for 245 credits.
