- Set the early bar for realistic, physically-consistent video generation
- Strong brand recognition and broad public familiarity
- Deprecated in 2026; OpenAI has discontinued the API
- Superseded by newer models from Google, ByteDance, and Kuaishou
Kuaishou
- Excellent character motion and dramatic, controllable camera moves
- Strong image-to-video animation from a single source frame
- Frame preservation needs careful checking on longer generations
- Native audio exists but is often disabled in third-party integrations
Runway
- Full creative production environment, not just a generation endpoint
- Strong iteration, editing, and referencing tools for professional workflows
- Audio still has to be added separately in most pipelines
- Steeper learning curve than simple prompt-and-generate tools
