When Will Sora Be Available to the Public?
Sadly, there is currently no release date for Sora. All the content that’s been going viral on the internet over the past 24 hours has come out of the announcement blog post published by OpenAI.
Interestingly, it doesn’t seem like OpenAI has even given a vague indication of when it might be made generally available – there’s not even been an indication that it will be released this year.
That’s quite unusual for such a large announcement, and could suggest it’s a long way off public release – but then 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.
What’s the Hold Up with Sora?
As we’ve covered, OpenAI is not prepared to release Sora to the public yet, unsatisfied that the video-generating technology has been sufficiently safety tested. This is good, considering the myriad of ethical issues relating to the creation of such lifelike videos – not to mention during a year with so many elections.
“We’ll be taking several important safety steps ahead of making Sora available in OpenAI’s products” “We are working with red teamers – domain experts in areas like misinformation, hateful content, and bias - who will be adversarially testing the model” it added.
OpenAI also says it is working on an AI video detection classifier that can identify whether a video has been produced by Sora or not.
This seems like a similar step to the one that was taken after ChatGPT was launched, after which the AI company launched a text classifier. However, it was later shut down due to its unreliability. When we tested it to see if it could uncover ChatGPT Plagiarism, it was unable to even detect content generated by itself.
How Does Sora Work?
“Sora is a diffusion model which generates a video by starting off with one that looks like static noise and gradually transforms it by removing the noise over many steps,” OpenAI said this week.
The technology works similarly to the GPT family of language models that power the company’s chatbot, ChatGPT. They all use a “transformer” architecture – a type of neural network that takes inputs and “transforms” them into outputs. They’ve also incorporated elements of DALLE-3, such as the recaptioning system.
OpenAI has fed Sora videos and images as units of data – or “patches”. “By unifying how we represent data” OpenAI days, “we can train diffusion transformers on a wider range of visual data than was possible before, spanning different durations, resolutions, and aspect ratios.
