The Motion Picture Association on Monday urged OpenAI to "take immediate and decisive action" against its new video creation model Sora 2, which is being used to produce content that it says is infringing on copyrighted media.
Following the Sora app's rollout last week, users have been swarming the platform with AI-generated clips featuring characters from popular shows and brands.
"Since Sora 2's release, videos that infringe our members' films, shows, and characters have proliferated on OpenAI's service and across social media," MPA CEO Charles Rivkin said in a statement.
OpenAI CEO Sam Altman clarified in a blog post that the company will give rightsholders "more granular control" over how their characters are used.
But Rivkin said that OpenAI "must acknowledge it remains their responsibility – not rightsholders' – to prevent infringement on the Sora 2 service," and that "well-established copyright law safeguards the rights of creators and applies here."
OpenAI did not respond to a request for comment.
Concerns erupted immediately after Sora videos were created last week featuring everything from James Bond playing poker with Altman to body cam footage of cartoon character Mario evading the police.
Although OpenAI previously held an opt-out system, which placed the burden on studios to request that characters not appear on Sora, Altman's follow-up blog post said the platform was changing to an opt-in model, suggesting that Sora would not allow the usage of copyrighted characters without permission.
However, Altman noted that the company may not be able to prevent all IP from being misused.
"There may be some edge cases of generations that get through that shouldn't, and getting our stack to work well will take some iteration," Altman wrote.
Copyright concerns have emerged as a major issue during the generative AI boom.
Disney and Universal sued AI image creator Midjourney in June, alleging that the company used and distributed AI-generated characters from their films and disregarded requests to stop. Disney also sent a cease-and-desist letter to AI startup Character.AI in September, warning the company to stop using its copyrighted characters without authorization.
