OpenAI plans to discontinue its Sora AI video generator, six months after the high-profile launch of a standalone app for the service, as the company works to simplify its portfolio of artificial intelligence products.?

The ChatGPT maker and Walt Disney?are also winding down their partnership, which had centered on Sora, OpenAI said Tuesday. Disney had previously agreed to license iconic characters including Mickey Mouse and Cinderella to OpenAI for use on Sora and to take a $1 billion stake in the startup. The deal was entirely in stock warrants rather than a cash licensing fee.

OpenAI debuted the Sora app in late September with the promise of making it easier for users to generate and share realistic-looking AI videos with each other in a quasi social network. The free app quickly rose to the top of Apple¡¯s App Store, but has since fallen in the rankings.?
