Our teams are constantly coming up with new ideas for features and ways to improve our Services. In order to do this, we also develop and improve the algorithms and machine learning models (an expression of an algorithm that combs through significant amounts of data to find patterns or make predictions) that make our features and Services work, including through generative AI features (artificial intelligence capable of generating text, images, or other media, using generative models. Generative AI models learn the patterns and structure of their input training data and then generate new data that has similar characteristics). We use algorithms and machine learning models for personalization, advertising, safety and security, fairness and inclusivity, augmented reality, and to prevent abuse or other Terms of Service violations.
