# Veo 3.1 vs Veo 3.1 Fast

Fast for a shot that stands alone. Full Veo the moment the clip has to match something else.

- **[Veo 3.1](https://meetkuro.com/models/veo-3.1.md)** — Google's flagship: generates dialogue and sound from the same prompt as the picture. from 83.5 credits · Google
- **[Veo 3.1 Fast](https://meetkuro.com/models/veo-3.1-fast.md)** — Veo without references, at roughly a third of the price. The single-shot tool. from 42 credits · Google

## What each costs

**Veo 3.1**

- 5s · silent: 83.5 credits (≈ $1.98)
- 5s · with audio: 167 credits (≈ $3.97)

**Veo 3.1 Fast**

- 5s · silent: 42 credits (≈ $1.00)
- 5s · with audio: 62.5 credits (≈ $1.48)

Dollar figures are approximate, at the Starter plan's rate of $19.00 for 800 credits.

## Which one

Same two aspect ratios, same 4, 6 and 8 second steps, same self-generated audio. A five-second silent take is 42 credits on Fast against 83.5 on the full model; with audio it is 62.5 against 167. On price alone Fast wins comfortably.

The difference that decides it is references. Full Veo 3.1 takes three reference images; Fast takes none. That means nothing about a Fast clip can be pinned to a character, product or look you already have, and a multi-shot sequence built on it will not hold together, however carefully each shot is prompted.

Both still accept a last frame, so frame-chaining works on either: render a shot, take its final frame, open the next take with it. That is a weaker form of continuity than reference images, but for b-roll, establishing shots and anything where the subject is not a specific recognisable person, it is usually enough.

So the rule is about the sequence rather than the shot. One clip, nobody who has to look like themselves: Fast, and take the saving. A run of clips that share a subject: full Veo, and do not try to economise your way around it. If you want a *silent* clip cheaply, Fast is also the answer, because Veo 3.1 Lite has no silent mode at all.

## When neither is the right pick

Each model's prompting guide names the jobs it hands to another model. Both lists, as the guides write them:

### Use something other than Veo 3.1 when…

- A single take must run longer than eight seconds: [Seedance 2.5](https://meetkuro.com/models/seedance-2.5.md).
- A vertical clip must hold a recurring character from reference pictures: [Seedance 2.5](https://meetkuro.com/models/seedance-2.5.md).
- A talking head should follow a voice track you already have: [OmniHuman 1.5](https://meetkuro.com/models/omni-human-1.5.md).

## Both are one pick in the same composer.

Switching models does not move your references or your library.
