OpenAI's Cameo Feature Sparks User Confusion Concerns

OpenAI had been using the 'Cameo' name for a feature within its video generation app Sora 2 that allowed users to insert digital likenesses of themselves into AI-generated videos.

Preliminary Injunction Follows Earlier Restraining Order

This latest preliminary injunction builds on a temporary restraining order that the court granted to Cameo back in November. Following that initial restraining order, OpenAI renamed the feature to "Characters," though the company continued to face legal pressure1
