Veo 3.1

### Google's photorealistic video model

Veo 3.1 is Google DeepMind's latest video generation model — the reference for photorealism and complex scene understanding across long clips.

Veo 3.1 Fast

### Quick iteration

Use veo-3.1-fast for quick generations and iterative workflows. Strong quality-to-latency ratio — ideal for production pipelines and A/B testing creative variants.

Veo 3.1 Lite T2V

### Cost-efficient text-to-video

veo-3.1-lite-t2v generates 720p-1080p clips from text prompts with lower per-call cost. Great for social video content and long-form scripted output.

Veo 3.1 Lite I2V

### Animate stills

veo-3.1-lite-i2v takes an input image and an optional motion prompt. Animate product shots, concept art, or character designs into short cinematic clips.

One REST API

### No Google Cloud account

Call Veo 3.1 via the ModelsLab REST API. No Google Cloud signup, no Vertex AI setup, no regional quota management — one ModelsLab key for every video model.

Pricing

### Transparent per-clip rates

Veo 3.1 Lite variants on ModelsLab price from ~$0.30 per 5-second clip. Free credits on signup so you can compare against Sora, Kling, Seedance, and Wan before committing.

Webhooks

### Async callbacks

Pass a webhook URL and ModelsLab POSTs the completed MP4 URL to your endpoint when generation finishes. Essential for batch video jobs and production pipelines.

SDKs

### Python & JavaScript

Official SDKs wrap every Veo endpoint. REST + OpenAPI spec for autogenerated clients in any language.
