Veo 3.1 API
Google video APIWith AudioVeo 3.1 is Google's latest line of video generation models, built for cinematic text-to-video and image-to-video creation with stronger prompt following, native audio workflows, and more controllable shots.
Use this page to compare Lite, Fast, Quality, Extend, 1080P, and 4K-oriented variants, then move from playground testing into a production API request with predictable payload fields.
Lowest cost starts at $0.2/s
720p: 40 credits/s - Text/Image to Video - Output seconds × 40
720p: 80 credits/s - Text/Image to Video - Output seconds × 80
1080p: 40 credits/s - Text/Image to Video - Output seconds × 40
1080p: 80 credits/s - Text/Image to Video - Output seconds × 80
4k: 80 credits/s - Text/Image to Video - Output seconds × 80
4k: 120 credits/s - Text/Image to Video - Output seconds × 120
USD estimates use $0.005/credit with the best annual plan. Final billing follows the selected Veo 3.1 variant, resolution, and task type.

The page follows the same API-first structure as the reference: test the model, understand the fields, then move into integration.
Text and image to video
Generate cinematic clips from prompts or starting images, with variants for fast iteration and higher-quality final output.
First and last frame control
Guide transitions with beginning and ending frames so motion, composition, and shot direction stay closer to the creative brief.
Native audio workflows
Build videos that account for sound, dialogue-like ambience, and richer audio direction where the selected Veo 3.1 mode supports it.
Extend and upscale paths
Use dedicated Extend, 1080P, and 4K variants when the workflow needs longer scenes, higher resolution, or post-generation retrieval.
From prompt test to Veo 3.1 API request
A compact integration path for teams that want to validate motion quality before wiring Veo 3.1 into an app or content pipeline.
1. Choose a variant
Select Lite, Fast, Quality, Extend, 1080P, or 4K based on iteration speed, output quality, and delivery target.
2. Add creative inputs
Provide a prompt, optional image references, duration, aspect ratio, resolution, and callback settings for the selected model.
3. Poll and deliver
Track the task until it succeeds, then retrieve the generated video URL for your app, campaign, or production pipeline.
What you can create with Veo 3.1 API
Use the API when your product needs repeatable, high-quality AI video output rather than one-off manual exports.

Veo 3.1 API questions
What is Veo 3.1 API best for?
It is best for cinematic text-to-video and image-to-video generation where motion quality, prompt control, frame guidance, and production-ready delivery matter.
What is the difference between Lite, Fast, and Quality?
Lite is the lower-cost entry point, Fast is tuned for quicker iteration, and Quality focuses on higher-fidelity output when creative direction is already clear.
Can Veo 3.1 use first and last frames?
Yes. Veo 3.1 workflows can use frame guidance to generate transitions between a starting frame and an ending frame, depending on the selected variant and payload.
Does Veo 3.1 support image-to-video?
Yes. The workflow supports prompt-only generation and image-guided generation, so you can animate product shots, characters, scenes, or visual concepts.
Which output formats are common for Veo 3.1?
Veo 3.1 video workflows commonly target short MP4 clips with 16:9 or 9:16 aspect ratios, with resolution options depending on the selected variant.
When should I use Extend?
Use Extend when you already have a generated video task and want to continue the scene rather than start a new clip from scratch.
Where can I test it before integrating?
Use the playground on this page to test prompts, references, resolution, aspect ratio, duration, and API payload behavior before moving into production.
Can I use Veo 3.1 API for commercial projects?
This page is configured for commercial-use workflows. For production use, review your account plan, credit balance, model availability, and any applicable content policy requirements.
