A federal district court in Northern California ruled in favor of Cameo, a platform that allows users to get personalized video messages from celebrities, and ordered OpenAI to stop using “Cameo” in its products and features.

OpenAI was using the “Cameo” name for its AI-powered video generation app Sora 2. Users could use that feature to insert digital likenesses of themselves into AI-generated videos.n a ruling filed Saturday, the court said the name was similar enough to cause user confusion, and rejected OpenAI’s argument that “Cameo” was merely descriptive, finding that “it suggests rather than describes the feature.”
