But whose data OpenAI used to create its groundbreaking system is a mystery. With ChatGPT, OpenAI helped popularize the now-standard industry practice of building more capable AI tools by scraping vast quantities of text from the web without consent. With Sora, launched in December, OpenAI staff said they built a pioneering video generator by taking a similar approach. They developed ways to feed the system more online video — in more varied formats — including vertical videos and longer, higher-resolution clips.
