OpenAI推出Privacy Filter模型，基于Apache2.0协议在Hugging Face和GitHub开源。该工具可本地运行、高度定制，通过深度语义理解精准识别非结构化文本中的敏感信息，摆脱传统机械匹配局限，为开发者提供高效隐私保护方案。
AI搜索引擎Perplexity因隐私问题被起诉，指控其“隐身模式”无效，用户聊天记录被共享给谷歌和Meta用于广告投放。诉讼称无论用户是否登录或开启隐私保护，对话内容均被自动共享，涉嫌严重侵犯隐私。
Perplexity AI因涉嫌未经用户同意向Meta和Google等第三方共享敏感对话数据，在美面临集体诉讼。诉状称即使用户开启隐身模式，其财务、税务等隐私信息仍可能被追踪工具泄露。公司回应尚未收到正式诉讼文件。
苹果在欧盟法规压力下，向第三方配件开放了iOS通知接入，但新增严格隐私条款，严禁将用户数据用于广告或画像，严防技术底层泄露。
