OpenAI's Sora: What It Is, How It Works, and Use Cases

The raise of artificial intelligence has started with the development of ChatGPT, a generative model that provides text information based on prompts. This model has grabbed everyone's attention towards generative AI. The next came generation of images based on textual prompts and images. The new-age revolution in AI is the developed of a model that generated video's based on the description provided by the user.

What is OpenAI Sora?

OpenAI Sora is an artificial intelligence model developed by OpenAI to create realistic and creative videos based on the textual description provided by the users. The main goal is to generate physical motion to solve problems that require real-time interaction.

This text-to-video model was unveiled in February 2024. The tool is not yet available to the public. OpenAI is taking steps to protect the generation of harmful and misleading content.

Features of OpenAI Sora

OpenAI Sora is a revolution in generative AI and multimodal AI. Though it is not released to the public, some of the features on the model, as mentioned on their website are ?

• One of the core capabilities of Sora is the generation of videos based on the textual description "prompts".
• It can generate complex scenarios with multiple characters in specific motion and an accurate background and environment.
• The model not only generates based on the prompts provided by the user but also tries to replicate how those things exist in the real world.
• The model is developed with a deep understanding of natural language to accurately interpret the prompts.
• It also has the capability to create multiple shots within a single video.
• Additionally, they have taken several safety measures before making it available for the public. They are building tools to help detect misleading, harmful, and biased content.

Applications of OpenAI Sora

OpenAI Sora's abilities can be applied in various creative and practical fields ?

• Advertising and Marketing ? The model can help businesses create promotional clips and content on social media from product or service descriptions.
• Education ? Educators and instructors can use Sora to create interactive educational videos for a particular concept to help students understand.
• Entertainment ? Sora can also be used to generate video clips of characters, backgrounds, and art sets based on the film description given. It gives an idea for the crew by visually representing their imagination.
• Video prototyping ? Sora can be used by companies to visualize and test concepts before they are fully developed. Like creating a video that shows how a service, product, or interface will work.
• Storyboarding and Concept Creation ? Sora can be widely used by filmmakers or illustrators to create visual storyboards or concept art within seconds by providing textual description.

How to Access OpenAI Sora?

At this point, OpenAI Sora is not open to the public. It has access only to the red teamers to assess the risks and harms. OpenAI also granted access to a few graphic designers and visual artists to evaluate the efficiency of the model and gain feedback for improvements.

How Does OpenAI Sora Work?

The working of OpenAI Sora is very similar to the working of large language models(LLM), where the model is trained on internet-scale data. While LLM's have text tokens, Sora has visual patches. The model is inputted with video, which are converted into patches by compressing video's into a lower dimensional latent space, later decomposing them into spacetime patches.

• The model trains a network to reduce the dimensions of visual data. The raw video is inputted to the network, and the output is latent representation.
• When a compressed video is provided, the network extracts a sequence of spacetime patches, which act as transformer tokens.
• Sora is a diffusion model. When noisy patches are given as input, the network interprets and converts them into clean patches.
• The model is developed in a way where the input is not necessarily textual description but can also be video or images.

Limitations of OpenAI Sora

The current model on which the team is working can still be improved. Some of the limitations as mentioned by OpenAI are ?

• The model might struggle to simulate complex scenarios, and also may not be able to visualize a few instances of cause and effect. For example, a cookie might not have the bitten mark after a character eats it.
• The model might also get confused for directions in prompts like left and right and specific camera trajectories.

Future of OpenAI Sora

This recent idea of generating a video using AI shows how rapidly AI has been implemented in different areas. Eventually, the tool is designed in a way to be implemented in healthcare and other fields. Additionally, there might be companies coming forward to develop tools using AI to better human life.

Conclusion

OpenAI Sora is the latest innovating in AI. This tool is developed by OpenAI which generated videos based on textual description. It will soon be open to public, which will change the working and efficiency of certain works in every industry. Specially business for marketing and adverting, film-making, and storytelling. Surely, it might not be the same as the real video.
