On February 15, 2024, OpenAI, which had astonished the world by announcing ChatGPT in late 2022, once again stunned the world with the unveiling of Sora. This technology, capable of creating videos up to a minute long from a text prompt, is undeniably set to be a breakthrough.
In this blog post, we will introduce the underlying methodologies and research behind this astonishing technology, based on the technical report released by OpenAI.
Incidentally, “Sora” means “sky” in Japanese. Although it has not been officially announced whether this naming was intentional, it is speculated to be so, given that their official release tweet featured a video themed around Tokyo.
