Quick take
Sora 2
OpenAI's legacy synced-audio video model for short text- or image-guided clips—still documented, but approaching a permanent API shutdown.
Best for
- Evaluating an existing Sora integration
- Short synced-audio experiments before shutdown
- Planning a migration to another video provider
Watch out for
The API shutdown is imminent. Treat every new dependency on Sora 2 as temporary and export anything you need to keep.
Veo 3.1 Fast
Google's lower-cost Veo 3.1 variant for quickly creating short video clips with native audio and output options up to 4K.
Best for
- Rapid ad and social-video variations
- Short clips that need generated audio
- Teams seeking a lower-cost route into Veo
Watch out for
Fast does not mean instant: Google says video requests can still take from seconds to several minutes at peak times. Generated files are retained for two days, and feature combinations vary by endpoint.
