Veo 3.1 - Oxen.ai

Try Veo 3.1 in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: google-veo-3-1 google/veo-3.1 is a video generation model. It excels in generating high-fidelity videos with native synchronized audio, including dialogue, sound effects, and ambient noise, along with improved narrative control and scene consistency over prior versions. Some other noteworthy features of google/veo-3.1 include image-to-video animation with reference images for consistent elements, scene extension, first/last frame interpolation, and multi-shot sequences.

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
