About veo_3_1

veo_3_1 is the platform entry for Veo 3.1. Google's documented family creates video with audio from text or images, using provider IDs such as veo-3.1-generate-preview rather than the platform's underscore spelling.

The corresponding Gemini API preview has a listed earliest shutdown date of 2026-10-22. Confirm the version supplied by the route. Wait for completion and inspect a playable video and its audio.
