OpenAI reveals Sora, its generative AI model that creates video from your text

With the model undergoing safety testing, the rest of us will have to wait a while before we can properly try out the promise Sora looks like delivering.

ChatGPT’s creator OpenAI has announced a new AI model called Sora that can create “realistic and imaginative scenes from text instructions” that are up to one minute long.

According to OpenAI, Sora is able to create complex scenes with multiple characters, specific types of motion, and accurate details of the subject and background to generate compelling characters that express vibrant emotions.

“The model understands not only what the user has asked for in the prompt, but also how those things exist in the physical world,” the company said in a post.

In a technical post, Sora can sample widescreen 1,920 x 1,080 videos, vertical 1,080 x 1,920 videos and everything inbetween. This lets Sora create content for different devices directly at their native aspect ratios.

OpenAI does admit that there are weaknesses with the current model, such as confusing spatial details like left and right or cause and effect. For example, a person might take a bite out of a cookie, but afterward, the cookie may not have a bite mark.

We converted this from an MP4 to a gif. the 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.

Sora is currently undergoing safety testing with red teamers — domain experts in areas like misinformation, hateful content, and bias. At the same time, OpenAI will leverage existing safety methods that were built for products that use DALL·E 3, which are applicable to Sora as well. So Sora will reject text input prompts that are in violation of our usage policies, like those that request extreme violence, sexual content, hateful imagery, celebrity likeness, or the IP of others.

Sora isn’t the first generative AI model for images, but the major difference between this and Bing Image Creator from Microsoft, is that the latter creates static images while Sora can create moving images.
