# Veo 3.1

**Badge:** New  
**Node type:** `video:veo3_1`  
**Category:** `video`

## Description

Auto-switches between variants based on inputs

## Pricing

- **Cost:** ~64 credits per seconds
- **Per-second rate:** The figure is the rate at a 5-second reference run. Our margin is progressive and steepest on the smallest runs, so a clip shorter than that can cost more per second, and a model priced with a flat multiplier is exact at every length. The charge is always computed from the real duration.

## Variant family

- **Family:** `veo3_1`
- **Is primary:** yes
- **All variants:** `video:veo3_1`, `video:veo3_1_fast`, `video:veo3_1_image_to_video`, `video:veo3_1_fast_image_to_video`, `video:veo3_1_first_last_frame_to_video`

## Canvas ports

These appear as port handles on the left side of the node.
