Sora

Sora is an AI model developed by OpenAI that generates realistic video scenes from textual descriptions. It can produce imaginative videos up to a minute long while maintaining visual quality and adhering to the user's prompt.

Key features:
- Generates highly realistic scenes based on text instructions
- Produces imaginative and creative video outputs
- Converts textual descriptions into video content
- Handles complex scenes with multiple characters, specific motions, and detailed backgrounds
- Simulates physical world dynamics, with some limitations for complex interactions and precise spatial details

How it works:
Sora uses a diffusion model framework, starting with a noisy video and gradually removing the noise over many steps to generate the final video. It employs a transformer architecture similar to GPT models and represents videos and images as collections of patches. The model also uses the recaptioning technique from DALL·E 3 to generate descriptive captions for the visual training data, ensuring the generated videos are faithful to the user's prompt.

Use of AI:
Sora is an AI model that uses deep learning techniques to understand language and generate corresponding video scenes.

AI foundation model:
Sora is built on a diffusion model framework and transformer architecture.

How to access:
Sora is currently available to a select group of "red teamers", visual artists, designers, and filmmakers for feedback and assessment. The public release date is anticipated sometime in 2024.

OpenAI is working on safety measures for Sora, including adversarial testing, detection tools, C2PA metadata, usage policies, and engagement with policymakers and educators. The company aims to prevent misuse and identify positive use cases for this new technology.
