Sample Outputs

Real outputs generated with Veo 3.1 Fast on deAPI.

“Japanese macaques sit in a steaming outdoor hot spring surrounded by snowy rocks while snow falls softly, one monkey slowly closes its eyes as snowflakes settle on its fur. Close, eye-level shot with a gentle push-in. Quiet trickle of water and the soft hush of falling snow.” “Japanese macaques sit in a steaming outdoor hot spring surrounded by snowy rocks while snow falls softly, one monkey slowly closes its eyes as snowflakes settle on its fur.

“Medium close-up of a weathered ship captain in a dark wool coat standing at the wheel on the bridge of a fishing trawler, thick grey fog outside the rain-streaked windows. He narrows his eyes and says in a gravelly voice: "Hold her steady, the harbour lights should be right ahead." Creaking hull, a low foghorn in the distance.” “Medium close-up of a weathered ship captain in a dark wool coat standing at the wheel on the bridge of a fishing trawler, thick grey fog outside the rain-streaked windows.

“A blue rally car slides sideways through a tight gravel bend on a forest stage, spraying stones and dust toward the camera, then accelerates away between tall pines. Low trackside camera, slight shake as it passes. Screaming engine, gravel pelting and a turbo whistle.” “A blue rally car slides sideways through a tight gravel bend on a forest stage, spraying stones and dust toward the camera, then accelerates away between tall pines.

“A hand-drawn 2D anime scene: a schoolgirl with short black hair stands at the railing of a school rooftop at dusk, the wind lifting her hair and scarf as she looks over a city of glowing windows under a pink and violet sky. Slow pan to the right. Cicadas, distant train bells and soft wind.” “A hand-drawn 2D anime scene: a schoolgirl with short black hair stands at the railing of a school rooftop at dusk, the wind lifting her hair and scarf as she looks over a city of glowing windows under a pink and violet sky.

“A single orange tent glowing from within beside a small campfire on a snowy lakeshore, bright green northern lights rippling and swirling across the starry sky above the mountains. Static wide shot on a tripod. Crackling fire and a faint, cold wind.” “A single orange tent glowing from within beside a small campfire on a snowy lakeshore, bright green northern lights rippling and swirling across the starry sky above the mountains.

Frequently Asked Questions

Veo 3.1 Fast is a faster, lower-cost version of Google DeepMind's Veo 3.1. It turns a text prompt into a single shot with synchronized sound, including spoken dialogue, and is built for quick iteration and volume.
Same inputs, lengths, resolutions and built-in audio, at a quarter of the price per second. The full Veo 3.1 is the choice for the most demanding final shots; Fast is the practical default for drafts, social clips and anything you generate in quantity.
Each clip is 4, 6 or 8 seconds long at 24 frames per second, in 720p (1280×720 or 720×1280) or 1080p (1920×1080 or 1080×1920). A length in between is rounded to the nearest supported one, and an exact tie goes to the shorter: 5 seconds becomes 4, 7 seconds becomes 6. The price follows the length you actually get.
Yes. Every clip comes with an audio track created in the same pass as the picture: dialogue with matching lip movement, sound effects, ambience and music. Write what should be heard into the prompt, and put spoken lines in quotes.
Price depends on the resolution and the length: $0.10 per second at 720p and $0.12 per second at 1080p. A 4-second 720p clip costs $0.40, an 8-second 720p clip $0.80 and an 8-second 1080p clip $0.96. Portrait and landscape cost the same. Call the price endpoint with your exact parameters before committing, and see the partner pricing section at https://deapi.ai/pricing.
Partner models run on our partners' infrastructure rather than on deAPI's own GPU network. deAPI acts as the gateway: same unified API, same key, same job flow.
Partner models are not available on the free tier. Make at least one payment to deAPI and your account moves to Premium. The model then appears in your /models response. Until then it is absent from your model list, and calling it by slug returns a plan error.
Make any payment to move your account to Premium, then open the playground and select Veo 3.1 Fast, or pass "model": "veo-3.1-fast" to the text-to-video endpoint. See https://docs.deapi.ai for code examples.
