What Is Sora OpenAI – How to Access Sora?
Technology is evolving by the day, and as far as AI goes, a machine-learning tool that transforms text prompts into a detailed video looks like the next big deal. OpenAI has recently announced its latest ground-breaking tech—Sora. Its introduction into the tech world has generated both excitement and skepticism.
Sora Open AI was introduced on February 15, 2024, as a generative video model. Although it is still a new product, it seems to be very promising. It is designed by combining transformer and diffusion models to offset the limitations of either model. Moreover, the Sora model presents high levels of consistency and increases video fidelity with recaptioning. However, it remains unknown when the model will be made available for public use.
This article gives a sneak peek of what to expect with the new Sora OpenAI.
What Is Sora OpenAI
Sora is Japanese for ‘sky’ and the same inspiration was used in the creation of this AI to express ‘limitless creative potential’. It is, however, too early to tell whether it lives up to this name. On the bright side, Sora appears to be more capable unlike the models that came before it, creating clips up to one minute long with consistent motion and characters.
Sora OpenAI was introduced to the world in February 2024 as the first artificial intelligence video model that showcased a high level of consistency, photorealism, and duration. This was after its predecessors like Runway’s Gen-2, Stable Video Diffusion, and Pike Labs Pika 1.0 compromised on those aspects. So far, the videos generated from this AI have only been shared on TikTok and X platforms. From there, you can tell that the output is quite impressive
What Is the Technology Behind Sora?
Sora utilizes the adapted version of the models built for DALL-E 3, which is OpenAI’s generative image platform but with advanced features for a more fine-tuned control. Sora is more of a diffusion transformer model that combines the image generation model behind Stable Diffusion with the token-based generators that power ChatGPT.
This model requires you to write a text prompt, and it then creates a video that matches the description of the prompt. The video is generated in a latent space and formed in 3D patches that are then put through a video decompressor to turn them into a standard, human-viewable output.
What Makes the Sora Model Different as a Generative Video Model?
The Sora model seems to be very promising. While it is not the first artificial intelligence video model, it has more to offer.
Solving Temporal Consistency
Sora stands out in this aspect in that it considers several video frames at once. This innovation comes as a solution to keeping objects consistent as they move in and out of view.
Combining Transformer and Diffusion Models
Sora uniquely combines the use of a diffusion model with a transformer architecture. The diffusion models are known to be great at generating low-level texture, but poor at global composition. The converse is true for the transformers. Hence, by combining these two models, you get the best of both worlds. Sora gives you the GPT-like transformer model that works to determine the high-level layout of the video, and a diffusion model to create the details. Another advantage of this hybrid architecture is that video generation is made computationally feasible. Since the process involves creating patches using dimensionality reduction, computation does not happen on every single pixel for every single frame.
Increasing Video Fidelity With Recaptioning
Sora also employs a recaptioning technique to capture the very essence of the user’s prompt. This means that before a video is created, it uses GPT to rewrite the user prompt so that it includes more detail.
How Can I Access Sora?
OpenAI is yet to release the data for Sora, stating that there is still more to be done to enhance the safety and security related to the model. It is likely to be available come April or May. This model is likely to be integrated into ChatGPT, just like the DALL-E 3 rather than be available as a standalone product. Also, it will be available as an API where third-party developers will be able to integrate its functionality into their products— this feature will be available later on.
Where Can Sora Be Applied?
Sora seems to be a promising tool for many industries. It can be used to create videos from scratch, extend existing videos, or fill in missing frames from videos. With these capabilities, the possibilities can be endless. Here are some key cases where Sora can come in handy.
Social Media
This generative video model will be embraced for social media use. It can be utilized to create short videos for different social media platforms such as YouTube shorts, Instagram reels, and TikTok. It will particularly come in handy in creating content that is impossible or difficult to film.
Prototyping and Concept Visualization
Sora videos can be used to quickly demonstrate ideas, even if AI will not be used in the final product. Filmmakers can also use this AI to create mockups of scenes before shooting them, designers can create videos of products before building them.
Advertisement and Marketing
Another potential fan base for the Sora tool is in advertising and marketing. Traditionally, creating promotional videos, product demos, and adverts is an expensive affair. Sora promises to make this process significantly cheaper.
Synthetic Data Generation
Synthetic data is necessary in cases where real data cannot be used due to privacy or feasibility concerns. Synthetic video data can be applied in training computer vision systems.
What Are the Limitations of Sora?
Just like any other AI, the current version of Sora is seen to have a number of limitations. For one, this model does not have an implicit understanding of physics and hence, does not always respect the ‘real-world’ physical rules. Moreover, the spatial position of objects may appear to shift unnaturally. Its reliability remains to be unclear, although all the examples presented by OpenAI are high-quality. To answer the questions on reliability, the public will have to wait until the tool is widely available.
FAQs
What Data Is Sora Trained On?
OpenAI has trained this model on publicly available videos, copyrighted videos, and other public domain content after having purchased the license in advance. The company has also employed a video-to-text engine that creates labels and captions from the ingested video files to fine-tune the model further.
What Are the Risks of Sora?
Since the product is still new, the risks are not fully described as of yet but they are likely to be similar to those of other text-to-video models. This includes the generation of harmful content, misinformation or disinformation, and biases and stereotypes.
Conclusion
Sora is new to the world and so far, this text-to-video generative AI model looks incredibly impressive. No doubt, Sora promises to introduce great potential across many industries. Many await its release with bated breath with the hope that it will exceed their expectations.
