Dunno, from the WSJ scoop: "CEO Sam Altman announced the changes to staff on Tuesday, writing that the company would wind down products that use its video models. In addition to the consumer app, OpenAI is also discontinuing a version of Sora for developers and won’t support video functionality inside ChatGPT, either."
If they were just shutting down the dedicated app and offering the same capabilities in the ChatGPT interface, I don't see why Disney would exit their deal?
Because Disney's deal was specifically and exclusively related to Sora, which was OpenAI's bizzare attempt at a TikTok like social networking site but using AI generated videos.
It was not a deal that allowed the use of Disney's characters for general purpose AI generated content using OpenAI tools.
