OpenAI’s latest Sora text-to-video model can create remarkably realistic content.

OpenAI’s latest Sora text-to-video model: OpenAI has made a significant breakthrough with the unveiling of its inaugural text-to-video model, named Sora, capable of producing astonishingly lifelike content.

There has been anticipation surrounding when the company would introduce its video engine, especially considering that many competitors, including Stability AI and Google, have already entered this domain. OpenAI may aim to perfect its technology before a formal launch. If its current trajectory continues, the quality of its outputs could surpass that of its peers.

According to the official page, Sora can generate “realistic and imaginative scenes” from a single text prompt, similar to other text-to-video AI models. However, what sets this engine apart is the underlying technology behind it.

Life-like Content

OpenAI asserts that its artificial intelligence possesses the capability to comprehend the presence of people and objects in the physical realm. This enables Sora to craft scenes featuring multiple individuals, diverse movements, facial expressions, textures, and detailed objects. Unlike some other AI-generated content, the videos generated by Sora generally avoid a plastic appearance or unsettling forms, though there are exceptions.

Moreover, Sora is designed to be multimodal. Users are said to have the ability to upload a still image as a foundation for a video. The elements within the image will be animated with meticulous attention to detail. Additionally, it can take an existing video and either extend its duration or fill in missing frames.

You can discover sample clips on OpenAI’s website and on X (formerly known as Twitter). One of the standout clips showcases a group of puppies frolicking in the snow. Upon closer inspection, you’ll notice that their fur and the snow on their snouts possess a remarkably realistic quality. Another impressive clip depicts a Victoria-crowned pigeon moving about just like a genuine bird.

Work in Progress

While these two videos from Sora may impress, they also reveal its imperfections. OpenAI acknowledges that its “model has weaknesses.” These include difficulties in accurately simulating object physics, distinguishing between left and right, and understanding instances of cause and effect. For instance, while you can command an AI character to bite into a cookie, the cookie may lack a visible bite mark.

Moreover, Sora tends to make peculiar errors. One humorous mishap involves a group of archaeologists excavating a large piece of paper, which inexplicably transforms into a chair before ultimately becoming a crumpled piece of plastic. Additionally, the AI struggles with words, as evidenced by misspellings such as “Oter” for “Otter” and “Danover” for “Land Rover.”

In the future, the company plans to collaborate with its “red teamers,” a group of industry experts, to assess critical areas for potential harms or risks. Their objective is to ensure that Sora does not generate false information, hateful content, or exhibit any biases. Furthermore, OpenAI intends to deploy a text classifier to reject prompts that contravene their policy, such as those requesting sexual content, violent videos, or celebrity likenesses, among other criteria.

There is currently no information available regarding the official launch date of Sora. We have reached out for details on the release and will update this story accordingly at a later time. In the interim, you can explore TechRadar’s list of the best AI video editors for 2024.
