I watched the introduction video of Sora, a text-video model. How did the AI model ‘sora’ get its name?

As of my last knowledge update in January 2022, I don’t have specific information about a model named “Sora” related to text-video synthesis. It’s possible that developments or new models have emerged since then. If “Sora” is a model introduced after that date, I recommend checking official sources from the organization or research team behind it to learn more about how the name was chosen or any specific details related to the model. Keep in mind that developments in the field of AI can occur rapidly, and new models may have been introduced since my last update.
