关于我们的私有AI计算架构的技术更新，该架构将实现持久化、跨设备的AI记忆，并符合设备端隐私标准。

人工智能正变得更具能力和直觉——记住重要的信息，理解你周围的世界，并按你的指示行动。隐私和信任是实现这一目标的核心，确保在AI系统不断进化以在你的设备上提供更持续协助的过程中，你的数据保持私密和安全。

今天，我们分享了如何将私有的、服务器端的记忆引入我们的私有AI计算平台。这一突破解决了现代AI中长期存在的难题：如何在维护通常仅限于设备端处理的严格隐私标准的同时，赋予助手跨设备的长期连续性。

将设备端隐私带入云规模记忆

借助这项新的技术能力，一个新的持久化记忆层将能够像云中的安全数字金库一样运作。在该模型下，用于协助你的信息被密封在专用的加密存储中，而解锁所需的加密密钥仅保留在你的个人设备上——确保你的数据对其他人（包括Google）都不可访问。

下图展示了此次私有AI计算架构更新的工作方式。当AI模型需要访问信息以协助你时，一个经过身份验证的端到端加密通道会将你的设备与云中受保护的隔离环境连接起来。这个空间，即“安全飞地”，在隔离内存中临时解密你的数据以处理请求，保存任何新的上下文，并立即重新加密，使你的信息保持私密，仿佛它从未离开过你的设备。

A technical update on our Private AI Compute architecture, which will enable persistent, cross-device AI memory with on-device privacy standards.

AI is becoming more capable and intuitive — remembering what matters, understanding the world around you, and acting at your direction. Privacy and trust are core to making that possible, ensuring your data stays private and protected as AI systems evolve to provide more continuous assistance across your devices.

Today, we are sharing how we will bring private, server-side memory to our Private AI Compute platform. This breakthrough resolves a longstanding dilemma in modern AI: how to give an assistant long-term continuity across devices while upholding the strict privacy standards typically limited to on-device processing.

Bringing on-device privacy to cloud-scale memory

With this new technical capability, a new persistent memory layer will be able to function like a secure digital vault in the cloud. Under this model, the information needed to assist you is sealed within dedicated, encrypted storage, while the cryptographic keys required to unlock it are held exclusively on your personal devices — ensuring your data is inaccessible to anyone else, even Google.

The diagram below shows how this update to Private AI Compute will work. When an AI model needs to access information to assist you, an authenticated, end-to-end encrypted channel connects your device to a protected, isolated environment in the cloud. That space, or “secure enclave,” temporarily decrypts your data in isolated memory to handle the request, saves any new context, and immediately encrypts it, keeping your information private as if it never left your device.
