Veo 3.1 Fast. Veo quality at iteration speed.
The fast lane of Google's Veo family. Same prompt language, same native audio, quicker clips at a lower credit cost. Built for drafting, exploring, and batch runs on Treza.
- 4 to 8 second clips
- 16:9 and 9:16
- Native audio
- First and last frame control
- Lower cost per clip
Most videos are not made in one prompt. Veo 3.1 Fast exists for the loop before the final render: try an angle, adjust the light, recast the scene, and see results while the idea is still warm. It keeps the Veo family's look and its native audio, trading some polish for speed and a friendlier price per clip.
In a Treza pipeline, Fast is the exploration engine. Fan a brief out into five prompt variants with a language model, render them all on Fast, pick the winner, and re-run just that prompt on full Veo 3.1. Or ship the Fast clip as-is: for social feeds, it is usually more than enough.
Built for the draft loop
Faster generations mean more takes per sitting. Iterate on framing, light, and action without watching a progress bar.
Same family, same audio
Fast keeps Veo's native soundtrack: dialogue, ambience, and effects generated with the picture.
Batch runs that stay affordable
Render a whole campaign of variants in parallel. The lower per-clip cost is what makes ten takes reasonable instead of reckless.
Keyframes included
First and last frame control works here too, so drafts can respect the same brand bookends as the final render.
What to make with Veo 3.1 Fast
Real prompts, and what comes back. Every one runs in Treza chat or as a node on the canvas.
“Five variations of a 6 second unboxing shot, different table surfaces”
A batch of drafts to pick a direction from in one run.
“A dog catches a frisbee on a beach, late afternoon, 9:16”
A social-ready vertical clip with surf and crowd ambience.
“Same scene as before, but at night in the rain”
A fast re-roll that keeps the framing and changes the mood.
“Storyboard beat: hands typing, screen glow, slow push-in”
A quick b-roll insert for a product story cut.
“A cheerful 'back to school' banner scene for a retail promo”
A seasonal ad variant you can regenerate per campaign.
“Test the same prompt in 16:9 and 9:16”
Both aspect ratios rendered side by side for the same idea.
Veo 3.1 Fast is one node on a canvas
Chain it with language, image, and video models, then publish the whole pipeline as an API.
- Step 01
Draft the brief
A language model node expands a one-line idea into a detailed, on-brand prompt before it ever reaches the model.
- Step 02
Generate with Veo 3.1 Fast
Run variants in parallel, compare against other models on the same prompt, and keep every result in run history.
- Step 03
Publish it as an API
The pipeline becomes a versioned endpoint. Your product calls it with the typed /invoke API or any OpenAI SDK.
Veo 3.1 Fast, answered
When should I use Veo 3.1 Fast instead of Veo 3.1?
Use Fast when you are exploring: drafts, prompt tests, batch variants, and social clips where turnaround matters more than final polish. Use Veo 3.1 when the shot is the deliverable. Many Treza pipelines use both, drafting on Fast and re-rendering the chosen prompt on Veo 3.1.
Does Veo 3.1 Fast include audio?
Yes. Fast generates dialogue, ambience, and effects in sync with the video, just like Veo 3.1.
Is the quality noticeably lower?
Fast trades some fine detail and consistency for speed. For feeds and drafts the difference rarely matters. For hero placements, re-render the final prompt on Veo 3.1.
How much does Veo 3.1 Fast cost on Treza?
Treza uses prepaid credits with no subscription. Each clip is charged at Veo 3.1 Fast's rate from your balance, and only successful generations are charged. Credit packs start at $5 and never expire.
Can I call Veo 3.1 Fast through an API?
Yes. Build a pipeline that uses Veo 3.1 Fast and publish it as a versioned HTTP endpoint. Call the typed /invoke API from your product, or point any OpenAI SDK at the OpenAI-compatible endpoint. If a better model ships later, swap it on the node without changing the API your product calls.
