15个不训练您数据的私人ChatGPT替代品

Every prompt entered into ChatGPT is stored on OpenAI's servers and can be used to train future models by default. A Stanford study published in October 2025 examined the privacy policies of six major AI providers, revealing that user inputs are routinely fed back into model training unless users explicitly opt out, which most do not. The scale is staggering, with ChatGPT processing over one billion queries daily from 700 million weekly active users. Research from Q4 2025 indicates that 34.8% of those inputs contain sensitive data, up from just 11% in 2023. The risks for enterprises are even sharper, as a LayerX Security report highlights that employees are pasting client names, financial figures, internal strategies, and proprietary code into a system that remembers everything.
