OpenAI unveils Sora, its latest AI tool that can make instant videos ...

The maker of ChatGPT on Thursday unveiled its next leap into generative artificial intelligence (AI) with a tool that instantly makes short videos in response to written commands.

San Francisco-based OpenAI's new text-to-video generator, called Sora, isn't the first of its kind. Google, Meta, and the start-up Runway ML are among the other companies to have demonstrated similar technology.

But the high quality of videos displayed by OpenAI - some after CEO Sam Altman asked social media users to send in ideas for written prompts - astounded observers while also raising fears about the ethical and societal implications.

"A instructional cooking session for homemade gnocchi hosted by a grandmother social media influencer set in a rustic Tuscan country kitchen with cinematic lighting," was a prompt suggested on X, formerly Twitter, by a freelance photographer from New Hampshire in the US. 

Altman responded a short time later with a realistic video that depicted what the prompt described.

The tool isn't publicly available yet, and OpenAI has revealed limited information about how it was built. 

The company, which has been sued by some authors and The New York Times over its use of copyrighted works of writing to train ChatGPT, also hasn't disclosed what imagery and video sources were used to train Sora.

The company pays an undisclosed fee to The Associated Press to license its text news archive.

OpenAI said in a blog post that it's engaging with artists, policymakers, and others before releasing the new tool to the public.

"We are working with red teamers - domain experts in areas like misinformation, hateful content, and bias - who will be adversarially testing the model," the company said. 

"We’re also building tools to help detect misleading content such as a detection classifier that can tell when a video was generated by Sora".
