Google Major Updates
Google Launches Private AI Compute for Cloud-Based Gemini Processing
Google introduced Private AI Compute, a new cloud system that gives powerful AI processing while still protecting user privacy, like on-device processing. It is designed for handling Gemini model requests securely. The system uses special TPUs with built-in Titanium Intelligence Enclaves (TIE) that create locked, protected spaces for AI processing. When a user sends a request, the device connects through an encrypted and verified channel, ensuring that Google’s engineers or administrators cannot access the data at any point.
Private AI Compute is built so that all data, inputs, and AI results disappear automatically after each session. Google also uses strong security methods like memory encryption, protection against physical attacks, no shell access, and hidden IP relays. A security review by NCC Group found a timing issue in the IP relay system and some denial-of-service risks, and Google is working on fixes. The platform will first be used on Pixel 10 devices to power new AI features such as Magic Cue improvements and smarter Recorder app summaries.
