Re-captioning is used to augment training data, by using a video-to-text model to create detailed captions on videos. [7] OpenAI trained the model using publicly available videos as well as copyrighted videos licensed for the purpose, but did not reveal the number or the exact source of the videos. [5]
A video generated using OpenAI's Sora text-to-video model, using 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.

OpenAI has released Sora, the video creation tool that it initially suggested may be too powerful to safely unleash. But the one specific feature of the system that had generated the most ...
Generative artificial intelligence (generative AI, GenAI, [1] or GAI) is a subset of artificial intelligence that uses generative models to produce text, images, videos, or other forms of data. [ 2 ] [ 3 ] [ 4 ] These models learn the underlying patterns and structures of their training data and use them to produce new data [ 5 ] [ 6 ] based on ...
The arrival of a tool as powerful as Sora only months after previous sophomoric attempts like the Will Smith video helps explain both the pace of innovation in the field as well as the ongoing ...
Sora is a diffusion model, meaning it "generates a video by starting off with a base video that looks like static noise and gradually transforms it by removing the noise over many steps ...
It can generate videos with resolution up to 1920x1080 or 1080x1920. The maximal length of generated videos is unknown. Sora's development team named it after the Japanese word for "sky", to signify its "limitless creative potential". [235] Sora's technology is an adaptation of the technology behind the DALL·E 3 text-to-image model. [237]
