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记忆功能，同时遵循设备端隐私标准。

人工智能正变得愈发强大且直观——它能够记住重要的信息，理解你周围的世界，并按你的指令采取行动。隐私与信任是实现这一目标的核心，确保在AI系统不断演进以在你的各类设备上提供更持续协助的过程中，你的数据始终保持私密与安全。

今天，我们分享了如何为私有AI计算平台引入私有的服务端记忆功能。这一突破解决了现代AI领域长期存在的一个难题：如何在维持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在云端充当一个安全的数字金库。在该模式下，用于协助你的信息被封装在专用的加密存储中，而解锁这些数据所需的加密密钥则仅保存在你个人的设备上——确保除你之外任何人都无法访问你的数据，包括Google在内也不例外。

下图展示了此次私有AI计算架构更新的工作原理。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端受保护的隔离环境连接起来。该空间（即“安全飞地”）会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信息，并立即重新加密，从而使你的信息保持私密状态，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.
