Sora's ability to fuse realism and fantasy is impressive, offering a wide range of potential applications, despite the ongoing challenges in simulating complex physical events and human emotions.
4. Understanding and simulating the physical world
![Exemple de Compréhension et simulation du monde physique de Sora](https://cdn.prod.website-files.com/65e218efa46d5aadb430f5ec/65e998f83f73b4277adf1c2b_65cea2483066a90d5a916700_Screenshot%25202024-02-15%2520at%252017.54.37.jpeg)
Sora aims to understand and simulate the physical world in motion, an ambitious goal that highlights its potential as a step towards general artificial intelligence.
- Understanding the physical world : The model has the ability to understand how objects exist in the physical world, allowing it to create realistic scenes.
- Simulation of specific movements : Sora can generate videos that include specific movements and interactions between characters and objects, reflecting real world dynamics.
Current limits
1. Material interactions: Sora doesn't have a perfect handle on the interactions between different materials, like glass breaking on a table.
2. Basic consistency: Coherence issues, such as the unwanted reversal of a runner's direction or the unexpected appearance of characters, may occur.
3. Combined problems: Combining multiple problems, such as the appearance of unwanted objects or physical problems, remains a challenge.
Despite its notable advances in the generation of text-based videos, Sora has limitations in terms of physical simulation and narrative coherence. These aspects, while presenting challenges, also highlight areas of potential improvement for future iterations of the model.
Safety and ethics
OpenAI takes several important security measures before making Sora available in its products, stressing the importance of ethics in AI development.
- Adversarial testing: Sora is tested by experts in areas such as misinformation, hateful content, and bias, to identify and mitigate potential risks.
- Classification and rejection of inappropriate prompts: Robust text and image classifiers are used to review and reject content prompts that violate OpenAI's content policy.
OpenAI's efforts to keep Sora safe and ethical are commendable, but continued regulation and monitoring will be crucial to prevent abuse and ensure the technology is used responsibly. Collaboration with policy makers, educators, and artists is critical to navigating the ethical and societal implications of creating AI-generated video content.
Pricing
At present, specific information on Sora's pricing has not been disclosed. OpenAI launched Sora in a test phase, accessible to some researchers and visual creation professionals to gather feedback and assess potential risks before possible commercialization.

FAQs
How do I get to Sora?
Access to Sora is currently restricted to a select group including researchers, visual artists, designers and filmmakers, invited by OpenAI or part of their Red Team. There is no public application process for beta access.
How does Sora work?
Sora transforms text prompts into realistic and imaginative video scenes using a delivery model. He starts with a video that looks like static noise that he gradually refines to match the prompt. This allows it to generate complex videos with multiple characters and detailed backgrounds. It can also animate still images or extend existing videos.
What are Sora's limitations?
While Sora marks a significant advance in AI-generated video content, it has limitations. It can have trouble simulating complex physics, understanding some cause-and-effect scenarios, and maintaining spatial details like left and right orientation. Additionally, it may encounter difficulties with accurately sequencing events over time.
