But most of these models are trained in the cloud, which means your data—photos, messages, typing patterns—gets sent to a server somewhere. That creates a tension: better personalization often comes at the cost of privacy. Researchers at MIT recently published a technique that could change that. They’ve shown a way to train AI models directly on everyday devices like phones, without needing to send your data anywhere else. ...
