# Veo 3 Fast

> Google Veo 3 fast tier — 720p, no audio. Cheapest Veo on Kyma at $0.135/sec. Async LRO ~30–60s.

## Overview

`veo-3-fast` is Google's Veo 3 fast tier — 720p output, no audio, fastest gen in the Veo family. Best default for budget cinematic clips, social shorts, and rapid iteration. Async long-running operation (LRO) pattern: submit returns immediately with a `job_id`, generation runs in the background, poll for completion.

Flagship tier with native audio is [`veo-3`](/models/veo-3).

## Use this when

* You need Veo's specific style on a budget.
* Audio not required — pure visuals are enough.
* 720p is acceptable (social, drafts, thumbnails).

## Pick something else when

* You need **native audio** (dialogue + ambient + lip-sync) → [`veo-3`](/models/veo-3).
* Cost is the only constraint → [`hailuo-02-768p`](/models/hailuo-02-768p) at \$0.42 flat for 6–10s.
* You want **multi-shot action** with audio → [`seedance-2-pro`](/models/seedance-2-pro).

## Example — text-to-video

```bash theme={null}
curl -X POST https://kymaapi.com/v1/videos/generations \
  -H "Authorization: Bearer $KYMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "veo-3-fast",
    "prompt": "A small orange cat walking across a kitchen counter, soft morning light",
    "duration": 4
  }'
```

## Example — image-to-video (first frame)

```bash theme={null}
curl -X POST https://kymaapi.com/v1/videos/generations \
  -H "Authorization: Bearer $KYMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "veo-3-fast",
    "prompt": "Camera slowly pushes in as the subject smiles",
    "image_url": "https://example.com/first-frame.jpg",
    "duration": 6
  }'
```

Async — POST returns `202` with `job_id`; poll `GET /v1/jobs/{id}` until status is `succeeded` (\~30–60s for 4s clips). Output URL is a durable Vercel blob (Kyma mirrors the upstream response before exposing the URL — no expiry concerns).
