OpenAI said Thursday night that it has paused the ability to generate videos depicting Martin Luther King Jr. in Sora, its new AI video app, after users produced what the company called disrespectful depictions of the civil rights leader. The move follows a joint statement with King Estate, Inc., which said it had worked with OpenAI to address how Dr. Martin Luther King Jr.’s likeness is represented in Sora generations.

The policy goes beyond one historical figure. OpenAI says authorized representatives or estate owners can now request that their likeness not be used in Sora cameos. The company acknowledged “strong free speech interests” in depicting historical figures but said public figures and their families should have control over how their likeness is used.

The pause arrives weeks after Sora’s launch, which opened the app to realistic AI videos of celebrities, historical figures, and users who opt in to having their own likeness re-created. Dr. Bernice King posted on Instagram the prior week asking people to stop sending her AI videos of her father; Robin Williams’s daughter made a similar request about her father. The Washington Post reported this week that Sora users had generated clips of Dr. King making monkey noises and wrestling Malcolm X, and crude videos of other figures remain easy to find.
