OpenAI, an artificial intelligence startup that created the chatbot ChatGPT, released a text-to-video model called Sora on Friday the 16th. This model allows users to generate videos up to 1 minute long using text commands.
Sora has the ability to generate complex scenes with multiple characters, specific types of actions, and precise details of the subjects and backgrounds. OpenAI showcased several videos generated by Sora on its official website, along with the corresponding text commands used for video generation.
OpenAI also stated that Sora can generate videos based on existing static images, accurately animating the content to create dynamic effects. The model can also utilize existing videos to extend the content or fill in missing frames.
However, OpenAI warned that the current model has limitations. For example, it may struggle to accurately simulate physical phenomena in complex scenes or understand causal relationships in specific situations. Additionally, the model may confuse spatial details, such as distinguishing between left and right.
Sam Altman, the CEO of OpenAI, mentioned on the X platform that the company has started “red-teaming” exercises for Sora and provided limited access to creators. Altman also shared multiple videos generated by Sora on the X platform earlier.
