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.
Seedance 2.5

Best for

- Longer AI clips with multiple shots
- Reference-heavy audiovisual production
Watch out for
fal bills by a video-token formula tied to frame size and duration, so aspect ratio changes the cost. Confirm which route supports the resolution and reference mix you need.
