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.
LTX-2.5 Fast
LTX's speed-optimized video model for text, image, or audio input, native sound, automatic duration, and output up to 4K.
Best for
- Fast video experiments with native audio
- Portrait or landscape output up to 4K
- Prompt-driven multi-shot clips with automatic duration
Watch out for
Fast does not mean every 4K job finishes instantly. Price grows from $0.09 to $0.30 per generated second, and permitted duration depends on resolution and frame rate.
