The preview slug is legacy — the upstream endpoint behind this model id is now the GA Veo 3.1 text-to-video endpoint (async/veo-3.1-generate-text2video). The id, URL slug, and pricing tier didn’t change so existing integrations keep working.

integer

default:"8"

Server-side constant for this model — Veo 3.1 text-to-video at RouterBase is fixed at 8s. Submit-time defaults are filled in by the schema’s hidden constants; don’t set this from your client.
