Meta 推出“隐身聊天”功能，实现零数据留存
meta ai 推出了“隐身聊天”，这是一种私密模式，在可信执行环境中处理数据，服务器不存储任何对话日志。
meta released 'incognito chat' for its ai assistant, ensuring conversation logs are never stored on servers and are deleted from devices once the session ends. mark zuckerberg stated that processing occurs in a trusted execution environment that meta cannot access, contrasting with rivals like google and openai that retain data for training or legal compliance. the feature addresses criticisms regarding chat indexing and data subpoena requests, though it raises questions about how meta will moderate misuse without access to conversation content.
