OpenAI, the company behind the viral chatbot ChatGPT, has just presented its very first video generative artificial intelligence model called Sora. This revolutionary system is capable of generating realistic and imaginative videos of up to 60 seconds in length from simple text instructions.
Sora represents an important step towards AI systems that can understand and simulate the real world, which is essential to achieving artificial general intelligence (AGI).
Sam Altman, CEO of OpenAI
How Sora works
The way Sora works is quite simple. The user simply enters a text description of the desired video scene and Sora then generates a high-quality video that matches that description. For example, given instructions such as "A woman walking in Tokyo", Sora can generate the video according to the description. Here's what it might look like:
A revolution!

Sora’s power lies in its ability to understand natural language and visualize the scene described in a realistic way, with characters and backgrounds rich in details. The model is even able to generate videos in different styles (realistic, animated, black and white, etc.) and fill in missing scenes in existing videos.
Technical challenges met
Creating a video generative AI model as advanced as Sora requires overcoming significant technical challenges:
- Temporal stability : Ensure consistency of objects and characters throughout the video, even when they are temporarily out of shot.
- Language comprehension : Correctly interpret user text instructions.
- Physical simulation : Accurately represent interactions between objects in the real world.
- Cause and effect : Understanding cause and effect relationships in a given scene.
According to OpenAI, Sora addresses these challenges by using cutting-edge deep learning techniques, including a generative adversarial network (GAN) trained on a large amount of video data.
Guarantees on ethical use
While extremely promising, a tool as powerful as Sora could be misused to generate deepfakes or disinformation. Aware of the risks, OpenAI has put in place strict ethical safeguards:
-
- A group of experts tests the model to detect biases and flaws.
- Technical tools are used to identify videos generated by Sora.
- Adding metadata ensures the provenance of the videos.
- Access to Sora is currently limited to a few select researchers.
Positive use cases
Despite these precautions, OpenAI believes in Sora's enormous potential to transform many sectors in a positive way:
-
- Video creation : automation of time-consuming tasks such as editing or special effects.
- Design : generation of storyboards or video prototypes to validate concepts.
- Advertisement : quick creation of personalized promotional videos.
- Entertainment : new interactive storytelling formats where viewers control the plot.
- Education : adaptive video manuals that adjust to students' level of understanding.
Additionally, advances in the quality of AI-generated videos will contribute to advances toward human-level artificial intelligence and beyond.
The Future of Video Creation
With Sora, OpenAI is pushing the boundaries of what is possible in terms of automatic video generation. Although the model is not yet available to the general public, the examples revealed suggest a not-so-distant future where AI will be able to create high-quality, tailor-made films, advertisements or educational content on demand. Some experts believe that Sora marks a decisive turning point, in the same way that ChatGPT was for text generation. Others warn against adopting AI tools too quickly, whose societal impacts are still poorly understood. In any case, with the rapid acceleration of progress in deep learning, our relationship with media and video content creation is about to be turned upside down. The question remains to what extent we will collectively be able to take advantage of these technological advances for a better future.
Sora: A GAN trained on 10,000 hours of videos
The technology behind Sora relies on a type of deep learning algorithm called GAN (Generative Adversarial Network). GANs consist of two competing neural networks:
-
- A generator that creates new content (here videos).
- A discriminator that evaluates the quality of generated content.
By opposing each other in this way, the two networks improve each other until they obtain results that are astonishingly realistic. To train its video GAN, OpenAI used a dataset comprising 10,000 hours of videos labeled with detailed text descriptions. It is by assimilating all of these text-video associations that Sora acquires its fine understanding of language and the physical world.
A “diffusion” process to transform noise into video
On a technical level, Sora uses a video generation method called "diffusion". The principle is to start with "video noise" made up of random pixels, then gradually transform it into a realistic and coherent video. Concretely, Sora applies thousands of small modifications to the initial video noise, under the control of the textual description provided by the user. Little by little, shapes are drawn, objects appear and interact until they converge towards the described scene. This diffusion technique, coupled with the power of GANs, is what allows Sora to generate such detailed videos with realistic characters in motion.
Custom videos up to 60 seconds
Unlike previous video generation models that were limited to a few seconds, Sora can produce high-quality, personalized clips up to 60 seconds. The video remains coherent thanks to a major innovation: the prediction of multiple future frames at each step of the broadcast process. Thus, Sora anticipates the trajectory of objects even when they temporarily move out of the frame. Another highlight: Sora can not only generate a video from scratch, but also extend an existing video or fill in missing frames. These features open the door to many creative applications.
