Open-Sora has the following differentiating advantages in video generation:
| comparison dimension | Open-Sora Advantage |
|---|---|
| degree of openness | Fully open source model weights and training code, while most competing products are closed source API services |
| cost-effectiveness | Training costs only $200,000 and the arithmetic cost of generating a single video is about 1/10th that of commercial products |
| hardware requirement | Supports single GPU operation, mainstream consumer graphics cards (e.g. RTX 4090) can generate 256p video |
| Customizability | Allows modification of model architecture and training process for research-oriented needs |
| performance | Version 2.0 Differs from OpenAI Sora by Only 0.69% in VBench Review |
Typical Case Comparison:
- Compared to Runway, which requires a subscription fee, Open-Sora can be deployed locally for free in perpetuity.
- Open-Sora supports longer video durations (16 seconds vs. the usual 4 seconds) than Stable Video Diffusion.
- Unlike the fixed resolution of Pika and other products, it supports flexible output from 144p to 768p.
These advantages make it particularly suitable for user groups with limited budgets but requiring a high degree of customization.
