## About

Veo 3.1 Lite Generate completes the Veo 3.1 family, released on April 2, 2026. Google positions it as its most cost-effective video model, aimed at developers building high-volume video applications, and states that it matches the generation speed of Veo 3.1 Fast. Cost, not turnaround, is what distinguishes the two tiers.

Veo 3.1 Lite Generate supports text-to-video and image-to-video with native audio generation, the capability shared across the whole Veo 3.1 family. Framing covers landscape (16:9) and portrait (9:16), output runs at 720p or 1080p, and duration is configurable at 4, 6, or 8 seconds with cost adjusting to the length you request.

The tier exists for applications where video generation is a continuous product feature rather than a production step. A social app that renders a clip for every post, a commerce catalog animating thousands of product shots, or a creative testing pipeline generating ad variants all hit a volume ceiling set by per-generation cost. Veo 3.1 Lite Generate raises that ceiling. Veo 3.1 Fast remains the iteration tier inside a creative workflow, and Veo 3.1 Generate remains the final-render tier for work that goes straight to distribution.

Rates for Veo 3.1 Lite Generate are listed on this page as N/A, with N/A breaking out resolution and duration tiers. Calling Veo 3.1 Lite Generate through AI Gateway adds usage and cost tracking, automatic retries, and provider failover on one API surface, which matters more across thousands of generations than it does for a single render.

## What to consider

Duration is the direct cost lever on Veo 3.1 Lite Generate. Clips run 4, 6, or 8 seconds, and cost adjusts with the length you request, so trimming a pipeline from 8 seconds to 4 changes the unit economics of every generation you run. Confirm provider rate limits before you route sustained production volume, so batch jobs do not queue unexpectedly. Validate output quality against a representative sample of your prompts before you standardize a pipeline on Veo 3.1 Lite Generate, since Veo 3.1 Generate remains the quality ceiling of the family.

## When to use

### Best For

- **High-volume video applications** where per-generation cost sets the ceiling on how much video a product can render
- **Product catalog animation** turning thousands of still product shots into short clips through image-to-video
- **Ad variant generation** for creative testing pipelines that produce many versions of one concept
- **User-generated video features** where a clip per user action has to stay economical
- **Rapid prompt iteration** at generation speed matching Veo 3.1 Fast

### Consider Alternatives When

- The clip is a finished deliverable. `google/veo-3.1-generate-001` applies full generation compute per request
- Complex motion or fine detail has to hold up. The standard Veo 3.1 tier is the quality ceiling of the family
- You want to revise a clip instead of regenerating it. `google/gemini-omni-flash-preview` edits across turns
- You need still images. `google/imagen-4.0-fast-generate-001` returns images rather than video

## Best for

- **High-Volume Video Applications:** Per-generation cost sets the ceiling on how much video a product can render
- **Product Catalog Animation:** Thousands of still product shots become short clips through image-to-video
- **Ad Variant Generation:** Creative testing pipelines produce many versions of the same concept
- **User-Generated Video Features:** A clip per user action stays economical at this tier
- **Rapid Prompt Iteration:** Generation speed matches Veo 3.1 Fast at a lower listed rate

## Consider alternatives

- **Final Production Renders:** `google/veo-3.1-generate-001` applies full generation compute for finished deliverables
- **Maximum Motion Fidelity:** Veo 3.1 Generate is the quality ceiling of the Veo 3.1 family
- **Conversational Video Editing:** `google/gemini-omni-flash-preview` revises a clip across turns instead of regenerating
- **Still Image Output:** `google/imagen-4.0-fast-generate-001` returns images rather than video clips

## Frequently asked questions

### How does Veo 3.1 Lite Generate differ from Veo 3.1 Fast?

Google positions Veo 3.1 Lite Generate as its most cost-effective video model and states that it matches the generation speed of Veo 3.1 Fast. Compare the rates on each model page for the current difference. Both sit below Veo 3.1 Generate, which applies full generation compute per request.

### What durations and resolutions does Veo 3.1 Lite Generate support?

Durations of 4, 6, or 8 seconds at 720p or 1080p, in landscape (16:9) or portrait (9:16). Cost adjusts with the duration you request. See the Specs table on this page for provider-specific options.

### Does Veo 3.1 Lite Generate generate audio?

Yes. Native audio generation runs across the Veo 3.1 family, covering ambient sound, effects, and dialogue described in the prompt, without a separate audio pass.

### Does Veo 3.1 Lite Generate support image-to-video?

Yes. Provide a reference image alongside a text description and Veo 3.1 Lite Generate animates it with the motion the prompt describes. Text-to-video works the same way without an image.

### When should I use Veo 3.1 Generate instead?

Use `google/veo-3.1-generate-001` when a clip is a deliverable and frame quality decides whether the output ships. Use Veo 3.1 Lite Generate when generation volume drives your cost and any single clip is one of many.

### How is Veo 3.1 Lite Generate priced?

Rates for Veo 3.1 Lite Generate are listed on this page as N/A, and N/A breaks out the resolution and duration tiers. Duration is the main lever, so a 4-second clip costs less than an 8-second one. AI Gateway reflects provider pricing with no markup.

### How do I use Veo 3.1 Lite Generate on AI Gateway?

Use the identifier `google/veo-3.1-lite-generate-001` with `generateVideo` from the AI SDK. AI Gateway handles provider routing and failover automatically.

### How does Zero Data Retention work with Veo 3.1 Lite Generate through AI Gateway?

Yes, Zero Data Retention is available for this model. Zero Data Retention is offered on a per-provider basis. See https://vercel.com/docs/ai-gateway/capabilities/zdr for details.
