Your old Facebook and Instagram posts were probably used to train Meta’s AI. You can’t opt-out as an American, but you can do this instead.

The post says the models weren’t trained on people’s private posts or their private messages, though it adds “we may use the data from your use of AI stickers, such as your searches for a sticker to use in a chat, to improve our AI sticker models.”

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.

Meta execs have talked about the company’s approach to AI training before.

Meta’s chief product officer, Chris Cox, said earlier this year that Meta’s text-to-image model, Emu, can produce “really amazing quality images” because Instagram has many photos of “art, fashion, culture and also just images of people and us.”

“We don’t train on private stuff, we don’t train on stuff that people share with their friends, we do train on things that are public,” he said at Bloomberg’s Tech Summit.

Besides user-generated content, Meta is also considering deals with news publishers for access to more training data, including news, photo, and video content, BI previously reported. AI competitors like Google and OpenAI have already made deals with many news publishers for training data.
