Veo 3.1

The currently public Crazyrouter Veo 3.1 model names are:
  • veo-3.1-fast
  • veo-3.1-quality
These are customer-facing public aliases. Internal canonical provider names are not exposed to customers.

​
Via Unified Video API

POST /v1/video/create
This page only covers the public capability surface that is already released:
  • text-to-video
  • single-image image-to-video
Provider-native referenceImages, style reference, and other Veo-specific modes are not part of the current public contract yet.

Google’s official Veo 3.1 docs also describe reference asset images and other provider-native capability details. The current Crazyrouter public page intentionally stays narrower: it only commits to text-to-video and single-image image-to-video under veo-3.1-fast and veo-3.1-quality. Additional Veo capability pages should be published only after the public route and validation artifacts are ready.
