数字服务应从平台主导转向用户代理，保障隐私与自主权。
The Next Paradigm Is User-Centric Agent, Not Platform-Centric Service
- 以用户目标为中心，由智能代理协调服务
- 平台优化指标不等于用户真实受益
- 适合关注隐私与自主性的用户及开发者
现代数字服务已发展为不可或缺的工具，支撑大规模信息系统。然而，当前以平台为中心的模式倾向于提升平台驱动的指标（如用户参与度、转化率），常与用户真实需求脱节。尽管平台技术（尤其是大语言模型）已显著进步，但平台服务质量的提升未必带来用户实际利益。平台中心服务往往优先考虑提供方目标，与用户利益存在冲突。本文主张未来数字服务应转向用户中心的智能代理：这类代理注重隐私保护，对齐用户定义的目标，并赋予用户对其偏好与行为的控制权。随着大语言模型和设备端智能的发展，这一愿景现已可行。本文探讨向用户中心智能转型的机遇与挑战，提出一个可落地的设备-云协同实现路径，并讨论所需的治理机制与生态结构。
原文摘要 · Abstract (English)
Modern digital services have evolved into indispensable tools, driving the present large-scale information systems. Yet, the prevailing platform-centric model, where services are optimized for platform-driven metrics such as engagement and conversion, often fails to align with users' true needs. While platform technologies have advanced significantly-especially with the integration of large language models (LLMs)-we argue that improvements in platform service quality do not necessarily translate to genuine user benefit. Instead, platform-centric services prioritize provider objectives over user welfare, resulting in conflicts against user interests. This paper argues that the future of digital services should shift from a platform-centric to a user-centric agent. These user-centric agents prioritize privacy, align with user-defined goals, and grant users control over their preferences and actions. With advancements in LLMs and on-device intelligence, the realization of this vision is now feasible. This paper explores the opportunities and challenges in transitioning to user-centric intelligence, presents a practical device-cloud pipeline for its implementation, and discusses the necessary governance and ecosystem structures for its adoption.
