OpenAI is shutting down its social media app Sora, which went viral last year as a place to share short-form videos generated by artificial intelligence but also raised alarms in Hollywood and elsewhere.

OpenAI said in a brief social media message Tuesday that it was “saying goodbye to the Sora app” and that it would share more soon about how to preserve what users had already created on the app.

“What you made with Sora mattered, and we know this news is disappointing,” it said.

The company behind chatbot ChatGPT released Sora in September as an attempt to capture the attention — and potentially advertising dollars — claimed by short-form videos on TikTok, YouTube or Meta-owned Instagram and Facebook.

But a growing chorus of advocacy groups, academics and experts expressed concern about the dangers of letting people create AI videos using whatever prompt comes to mind, leading to the proliferation of nonconsensual images and realistic deepfakes — a recording or image that seems real but has been manipulated with AI.

OpenAI was forced to crack down on AI creations of public figures doing outlandish things — among them, Michael Jackson, Martin Luther King Jr. and Mister Rogers — but only after an outcry from family estates and an actors’ union.

Disney, which made a deal with OpenAI last year to bring its characters to Sora, said in a statement Tuesday that it respects OpenAI’s “decision to exit the video generation business and to shift its priorities elsewhere.”

“We appreciate the constructive collaboration between our teams and what we learned from it, and we will continue to engage with AI platforms to find new ways to meet fans where they are while responsibly embracing new technologies that respect IP and the rights of creators,” Disney’s statement said.
