OpenAI said in a brief social media message on Tuesday that it was "saying goodbye to the Sora app", and it would share more soon about how to preserve what users already had created.
"What you made with Sora mattered, and we know this news is disappointing," it said.
The company behind ChatGPT released Sora in September as an attempt to capture the attention, and potentially advertising dollars, that follow 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 on just about anything they can type into a prompt, leading to the proliferation of non-consensual images and realistic deepfakes in a sea of less harmful "AI slop".
OpenAI was forced to crack down on AI creations of public figures - among them, Michael Jackson, Martin Luther King Jr and Mister Rogers - doing outlandish things, but only after an outcry from family estates and an actors' union.
Disney, which made a deal with OpenAI in 2025 to bring its characters to Sora, said on Tuesday that it respected "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.
