evidence: While users in the European Union can opt out of having their data used to train Meta's AI models, such an option doesn't exist in the US or Australia. Making sure your audience isn't set to "public" should keep any of your new posts and photos from being used for the company's AI training. The section on generative AI from Meta's privacy center says, "We use public posts and comments on Facebook and Instagram to train generative AI models for these features and for the open-source community. We don't use posts or comments with an audience other than Public for these purposes." [...] Likewise, Meta says it may use your interactions with AI features, such as "messages to AI chats, questions you ask and images you ask Meta AI to imagine for you." It may also save details and context about you from conversations you have with AI characters.
