As of today, Sora is being made accessible to red teamers for the assessment of critical areas concerning potential harms or risks. We are also extending access to visual artists, designers, and filmmakers, seeking valuable feedback to enhance the model’s utility for creative professionals.

This early disclosure of our research progress aims to involve and gather insights from individuals outside of OpenAI, offering a glimpse into the forthcoming AI capabilities.

Sora exhibits the ability to generate intricate scenes featuring multiple characters, specific motion types, and precise details of subjects and backgrounds. Beyond comprehending user prompts, the model possesses a deep understanding of how these elements exist in the physical world.

The model’s language understanding is profound, enabling accurate interpretation of prompts and the creation of compelling characters expressing vibrant emotions. Sora can craft multiple shots within a single video, maintaining the persistence of characters and visual style.

However, it’s important to acknowledge the current model’s limitations. Challenges may arise in accurately simulating the physics of complex scenes, and there might be instances where cause and effect relationships are not fully understood. For instance, a person taking a bite out of a cookie may not reflect in a bite mark on the cookie.

Spatial details in prompts could be confused, such as left and right orientations, and the model may face difficulties in precisely describing events unfolding over time, like following a specific camera trajectory.

Safety measures are a top priority before Sora becomes available in OpenAI’s products. Red teamers, experts in misinformation, hateful content, and bias, will conduct adversarial testing. Detection tools, including a classifier to identify Sora-generated videos, are being developed, and C2PA metadata may be included in the future.

Leveraging existing safety methods developed for products like DALL·E 3, OpenAI will employ text and image classifiers to ensure adherence to usage policies, rejecting prompts that violate guidelines and reviewing generated videos for compliance.

Engaging with policymakers, educators, and artists globally, OpenAI aims to address concerns and identify positive use cases for this transformative technology. Recognizing the unpredictability of technology use, OpenAI emphasizes learning from real-world applications to refine and release increasingly safe AI systems.

Sora employs a diffusion model, generating videos by transforming static noise gradually. With foresight into multiple frames, the model maintains subject consistency even when temporarily out of view. Using a transformer architecture akin to GPT models, Sora achieves superior scaling performance.

Data representation unification through patches, similar to GPT tokens, enables training diffusion transformers on a wider range of visual data, spanning different durations, resolutions, and aspect ratios.

Building on DALL·E and GPT research, Sora utilizes the recaptioning technique from DALL·E 3, generating descriptive captions for visual training data. This ensures faithful adherence to user text instructions in the generated video.

Sora’s capabilities extend beyond text-only instructions. The model can animate an existing still image, bringing its contents to life with precision and attention to detail. It can also extend existing videos or fill in missing frames.

Sora serves as a foundational model for understanding and simulating the real world, marking a crucial milestone towards achieving Artificial General Intelligence (AGI).
