Sora- Open AI’s New Text to Video Model


OpenAI, an AI research and development company has revealed on 16th February 2024, a text-to-video model, called Sora which could raise the bar for what’s possible in generative AI.  The term “Sora” refers to “sky” in Japanese. It is speculated that they intentionally named it after Tokyo, as suggested by their official release tweet featuring a themed video.

 

Like Google’s text-to-video device Lumiere, Sora’s availability is limited. Unlike Lumiere, Sora can generate videos as long as 1 minute long.

 

Text-to-video has become the latest arms race in generative AI as OpenAI, Google, Microsoft, and more look beyond text and image generation and seek to cement their situation in a sector projected to reach $1.3 trillion in revenue by 2032. Consumers who have been fascinated by generative AI development since ChatGPT arrived a little more than a year ago will be influenced by it.

 

According to a post on Thursday from OpenAI, maker of both ChatGPT and Dall-E, Sora will be available to “red teamers,” or experts in areas like misinformation, bias, and hateful to  adversarial test the model. Adversarial testing will be especially important to address the potential for influencing deep fakes which is a major area of concern for the use of AI to create images and videos. Additionally, it would be available to visual artists, designers, and filmmakers to gain additional feedback from creative professionals. 

 

Introduction to the new AI model

 

Sora, a Generative AI model introduced on February 16, 2024 created and freely announced by OpenAI – – an artificial intelligence research company in February 2024. OpenAI was founded by a group of entrepreneurs and researchers Elon Musk and Sam Altman in 2015. OpenAI is supported by Microsoft, and by several other investors such as Thrive Capital, Micro VC, and many others. It has also created Dall-E and AI text-to-image generators and trained  GPT-3.5, and GPT-4 & the latest and most powerful OpenAI model.

 

Sora is able to generate videos for as long as a minute extended period maintaining visual quality and commitment to the user’s brief. Sora can generate complex scenes with multiple scenarios, specific types of movement, and accurate details of the main subject and the background. The artificial intelligence model understands what the user has prompted, yet additionally how the details exist in the physical world. OpenAI wrote in its announcement. Sora serves as a foundation for models that can understand and simulate the real world,”

How Sora Works?

 

Sora is a diffusion AI model that, like ChatGPT, uses the Transformer architecture, introduced by Google researchers in a 2017 paper. The world is multimodal,” OpenAI COO Brad Lightcap told CNBC in November. “If you think about the way we as humans process the world and engage with the world, we see things, we hear things, we say things — the world is much bigger than text. So to us, it always felt incomplete for text and code to be the single modalities, the single interfaces that we could have to know how powerful these models are and what they can do.

 

Sora has so far just been available to a small gathering of safety testers, or “red teamers,”. They test the model for vulnerabilities in areas like misinformation and bias. The company hasn’t released any open demonstrations beyond 10 sample clips available on its website, and it said its accompanying technical paper will be released later.

 

OpenAI also said it’s building a “detection classifier” that can identify Sora-generated video clips, and that it plans to include certain metadata in the result to help with identifying AI-generated content. Furthermore, it’s the same type of metadata that Meta is hoping to use to identify AI-generated images this election year.

When Will Sora be accessible to the public? 

 

Security researchers are currently putting Sora through serious hardships to ensure its safety and security before releasing it to the general society and assessing “critical dangers.”

Artists, filmmakers, and designers, including OpenAI, have been given access to Sora. (In this version, OpenAI is no longer speaking passively about itself.)

 

Some in-the-loop accounts on the OpenAI gathering seem to signal that there will be a waiting rundown rolled out at some point, which will be the main chance to get your hands on it.

 

Unfortunately, there is no sign of when we’ll be able to join Sora. Furthermore, all the content that’s been becoming a web sensation on the internet over the past hours has come out of the announcement blog entry published by OpenAI.

 

Interestingly, it doesn’t seem like AI application has even given a vague indication of when it very well may be made generally available – there’s not even been an indication that it will be released for the current year.

 

That’s quite unusual for such a large announcement, and could suggest it’s far off open release – however at that point again, OpenAI does admit that it’s sharing its research early. With the speed that the artificial intelligence industry has moved over the past two years, the true launch date is anyone’s guess.
