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.

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.
• Cost is the only constraint → hailuo-02-768p at $0.42 flat for 6–10s.
• You want multi-shot action with audio → seedance-2-pro.

Example — text-to-video

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)

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 Vertex response before exposing the URL — no expiry concerns).
