Available Veo 3.1 Official API Models on Vidgo API

Veo 3.1 Lite Official

Lowest-cost Veo 3.1 Official option for text-to-video, single-image, and first/last-frame iteration. Supports 720p and 1080p, with 1080p limited to 8-second jobs.

Veo 3.1 Fast Official

Balanced official Veo 3.1 tier with 720p, 1080p, 4K, optional native audio, and reference mode for production-speed creative workflows.

Veo 3.1 Quality Official

Higher-quality official Veo 3.1 tier for premium output, native audio, reference guidance, and 4K delivery when visual fidelity matters more than minimum cost.

Key Features of Veo 3.1 Official API

Official Google Veo 3.1 access with model-tier choice, native audio, image control, 4K output paths, and async delivery.

One Official Veo 3.1 Family, Three Cost Profiles

Veo 3.1 Official on Vidgo API exposes Lite, Fast, and Quality variants through the same submit workflow. That lets teams use a single integration while routing jobs by cost, speed, and output quality instead of maintaining separate video stacks.

Lite for low-cost iteration
Fast for balanced production jobs
Quality for higher-fidelity output

Native Audio Control

Each request can choose whether to generate video with sound. That makes cost and output intent explicit: keep silent runs cheaper for internal previews, or enable audio when the final clip needs ambience, motion sound, or a richer social-ready result.

sound true or false per request
Separate silent and audio pricing
Useful for preview and final-render pipelines

Text, Image, First/Last Frame, and Reference Modes

Use pure prompts for text-to-video, one image for image-to-video, two images for first/last-frame control, or three reference images on supported variants. The endpoint keeps the control surface compact while covering the most common production video workflows.

1 image for image-to-video
2 images for first/last-frame mode
3 images for reference mode on Fast and Quality

4K Path with Async Task Delivery

Fast and Quality variants support 4K options for jobs that need a higher-resolution delivery path. Submit the request, receive a task ID, then poll status or use a callback URL to collect the generated video when the async job finishes.

4K available on Fast and Quality
Returns task_id immediately
Poll status or receive callback results

Frequently Asked Questions about Veo 3.1 Official API

What is Veo 3.1 Official API on Vidgo API?

Veo 3.1 Official API gives developers access to the official Google Veo 3.1 model family through Vidgo API. It includes Lite, Fast, and Quality variants for different cost and quality needs.

What model IDs should I use?

Use veo3.1-lite-official, veo3.1-fast-official, or veo3.1-quality-official in the model field.

Does Veo 3.1 Official support audio?

Yes. Use the sound parameter to request audio or silent output. Audio and no-audio jobs have different per-second rates.

What image input modes are supported?

One image creates image-to-video, two images use first/last-frame mode with generation_type set to frame, and three images use reference mode with generation_type set to reference on Fast and Quality.

What limitations should I know before integrating?

Prompts are limited to 1000 characters. Duration supports 4, 6, or 8 seconds. Reference mode requires exactly 3 images and 8 seconds. Lite supports at most 2 images, does not support reference mode, does not support 4K, and Lite 1080p supports 8 seconds only.

How does async delivery work?

Submit a job to the generate endpoint and receive a task_id. Your backend can poll status by task_id or include callback_url to receive the result asynchronously.

When should I choose Lite, Fast, or Quality?

Choose Lite for low-cost iteration, Fast for balanced production jobs and 4K access, and Quality when you need the strongest output quality or premium 4K results.

When is Veo 3.1 Official not the right choice?

It is not ideal if you need one request to generate more than 8 seconds, Lite 4K output, or a Lite reference workflow with three images.
