OpenAI, the creator of ChatGPT and image generator DALL-E, said it was testing a text-to-video model called Sora that would allow users to create realistic videos with a simple prompt.

The Microsoft-backed company said the new platform was currently being tested but released a few videos of what it said was already possible, with the accompanying input made to generate the video.

“Sora can generate videos up to a minute long while maintaining visual quality and adherence to the user’s prompt,” OpenAI said in a blog post.

The model could also take an existing still image and generate a video from it, the company said.

OpenAI CEO Sam Altman on X said the company was “offering access to a limited number of creators” in a testing phase.

He also invited users to suggest prompts on X, the convincing results of which he posted on the platform a few moments later.

These included a short video of two golden retrievers podcasting on a mountain. Another showed a “half duck half dragon (that) flies through a beautiful sunset with a hamster dressed in adventure gear on its back.”

The San Francisco-based startup warned that the “current model has weaknesses” such as confusing left and right or failing to maintain visual continuity throughout the length of a video.

In its announcement, the company said that safety would be key and that Sora would face adversarial testing, known as red-teaming, in which dedicated users try to make the platform malfunction, produce inappropriate content or go off the rails.
