“Cinematic coffee commercial: steamed milk poured into a ceramic cup of espresso in slow motion forming delicate latte art, warm morning cafe ambience with soft jazz piano and gentle crowd murmur, cozy golden atmosphere”

What is Veo 3.1 Fast?
Veo 3.1 Fast (veo3.1-fast) is the speed-optimized tier of Google’s Veo 3.1 video model. It renders 4, 6 or 8 second clips at 720p or 1080p with the line’s signature feature intact: native audio generation. Cafe ambience, birdsong, traffic, a line of dialogue — the soundtrack is synthesized alongside the frames, in sync, with no separate audio pass.
That combination — fast turnaround, strong prompt adherence, and sound baked in — makes Veo 3.1 Fast the go-to for short-form content where audio sells the scene: product spots, social hooks, reaction clips and ambient loops. On Viddra it bills at a flat $0.24/sec whether audio is on or off, so there’s no reason to ever render it silent.
Viddra serves Veo 3.1 Fast behind one unified API — no Google Cloud project, no Vertex AI setup, no waitlist. Click Generate to use the browser playground, or POST to the same endpoint you’d use for every other model.
