Creating video from text
Sora, an AI model, has the remarkable ability to generate lifelike and creative video sequences based solely on textual prompts.
We’re educating AI to comprehend and replicate dynamic physical environments, aiming to develop models that assist individuals in tackling challenges necessitating real-world engagement.
Meet Sora, our text-to-video model. Capable of producing videos lasting up to a minute, Sora ensures high visual fidelity and fidelity to the user’s input.
Prompt: A stylish woman walks down a Tokyo street filled with warm glowing neon and animated city signage. She wears a black leather jacket, a long red dress, and black boots, and carries a black purse. She wears sunglasses and red lipstick. She walks confidently and casually. The street is damp and reflective, creating a mirror effect of the colorful lights. Many pedestrians walk about. sorce https://openai.com/sora
Today, Sora is being made accessible to red teamers for evaluating critical areas for potential harm or risks. Additionally, we are extending access to visual artists, designers, and filmmakers to gather insights on enhancing the model to best serve creative professionals.
By sharing our research advancements early, we aim to collaborate with and receive feedback from individuals beyond OpenAI, offering the public a glimpse into upcoming AI capabilities.
Prompt: Historical footage of California during the gold rush.
Prompt: The camera follows behind a white vintage SUV with a black roof rack as it speeds up a steep dirt road surrounded by pine trees on a steep mountain slope, dust kicks up from it’s tires, the sunlight shines on the SUV as it speeds along the dirt road, casting a warm glow over the scene. The dirt road curves gently into the distance, with no other cars or vehicles in sight. The trees on either side of the road are redwoods, with patches of greenery scattered throughout. The car is seen from the rear following the curve with ease, making it seem as if it is on a rugged drive through the rugged terrain. The dirt road itself is surrounded by steep hills and mountains, with a clear blue sky above with wispy clouds.
Safety Measures :
Prior to integrating Sora into OpenAI’s products, we’re implementing several crucial safety protocols. Collaboration with red teamers—experts in domains like misinformation, hateful content, and bias—is underway to conduct adversarial testing on the model.
Furthermore, we’re developing tools to detect potentially misleading content, such as a classifier designed to identify videos generated by Sora. Future deployments may incorporate C2PA metadata.
Alongside pioneering new techniques for deployment readiness, we’re leveraging existing safety methodologies established for products like DALL·E 3, which are also relevant to Sora.
For instance, within an OpenAI product, our text classifier will screen and reject prompts violating usage policies, including those requesting extreme violence, sexual content, hateful imagery, celebrity likeness, or others’ intellectual property. Robust image classifiers have been developed to scrutinize every frame of generated videos, ensuring adherence to usage policies before user access.
Engagement with policymakers, educators, and artists globally is prioritized to understand concerns and explore positive applications for this technology. Despite extensive research and testing, we acknowledge the impossibility of foreseeing all potential uses, both beneficial and harmful. Therefore, we consider real-world usage crucial for refining and releasing progressively safer AI systems over time.
Prompt: The camera directly faces colorful buildings in Burano Italy. An adorable dalmation looks through a window on a building on the ground floor. Many people are walking and cycling along the canal streets in front of the buildings.
Research Techniques:
Sora operates as a diffusion model, initiating video generation from a base resembling static noise and gradually refining it by eliminating noise across numerous iterations.
It has the capability to produce entire videos instantaneously or elongate existing ones. By endowing the model with foresight spanning multiple frames, we’ve overcome the challenge of maintaining continuity even when a subject temporarily exits the frame.
Similar to GPT models, Sora utilizes a transformer architecture, ensuring enhanced scalability.
Videos and images are represented as collections of smaller data units called patches, akin to tokens in GPT. Standardizing data representation enables training diffusion transformers on a broader range of visual data, including various durations, resolutions, and aspect ratios.
Building upon prior research in DALL·E and GPT models, Sora employs the recaptioning technique from DALL·E 3, generating detailed captions for visual training data to enhance fidelity to user instructions in generated videos.
Beyond generating videos solely from text prompts, the model can animate existing still images with precision and attention to detail, as well as extend existing videos or fill in missing frames. Further details can be found in our technical report.
Sora lays the groundwork for models capable of comprehending and simulating the real world, marking a significant step toward achieving Artificial General Intelligence (AGI).
