Switch between them with one field
Both models sit behind the same endpoint, API key and polling flow, so testing one against the other is a one-line change:
curl -X POST "https://videogenapi.com/api/v1/generate" \
-H "Authorization: Bearer $VIDEOGEN_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model": "veo3", "prompt": "A runner crosses a rain-soaked street at night, neon reflections, tracking shot", "duration": 8}'Replace "veo3" with "veo-31" to run the same prompt on Veo 3.1 Fast. Poll GET /api/v1/status/{generation_id} until the status is completed. Full details on the Veo 3 Fast and Veo 3.1 Fast pages, and in the generate reference.
