OpenAI has closed its ai video app, Sora, which has resulted in the cancellation of a deal with Disney reportedly worth $1 billion. The closure of the app and the cancellation of the deal appear to be linked, although it is unclear which party initiated the cancellation. Reports vary on whether OpenAI or Disney ended the deal, with some suggesting OpenAI's closure of Sora led to the cancellation, while others imply Disney was the one to cancel the agreement.
