よくある質問
神经网络是一种模拟人类大脑结构的计算模型，由大量类似神经元的连接点组成。传统的计算机处理方式像是一个“超级算盘”，依赖人类预设的死板指令和规则进行快速计算，但它不会自我总结规律。而神经网络通过模拟大脑的“万物互联”结构，使机器能够从海量数据中提炼模式，从而实现像人一样的感知、思考和自我进化。
这种现象被称为 AI 的“幻觉”。因为大模型本质上是一个“概率预测引擎”，它并不真正理解什么是“事实”，而是根据语境计算下一个字出现的最高概率。当模型缺乏相关知识或数据模糊时，为了完成回复任务，它会根据概率拼凑出一个听起来合理但实际上是虚构的答案。通过引入 RAG（检索增强生成）技术或要求 AI 进行“自我批判”，可以有效减少这种现象。
大模型更像是一个“博学的大脑”，主要负责处理信息、回答问题和生成内容，但它通常没有自主行动的能力。而智能体是在大模型的基础上安上了“手脚”，它具备感知、决策、目标和自主行动四个要素。例如，你只需给智能体一个模糊的目标（如“我饿了”），它能自主规划步骤、调用工具并完成任务，而不仅仅是提供建议。
这源于 AI 计算的底层逻辑差异。普通的 CPU 像是一位全能教授，擅长处理复杂的逻辑但一次只能做一两件事；而 GPU 像是一万个只会简单算术的小学生，虽然单个能力有限，但能进行海量并行计算。由于 AI 训练和推理涉及极大规模的重复性数学运算，GPU 的“人海战术”在效率上远超 CPU，因此成为了 AI 时代的算力核心。
编写高质量提示词的黄金法则是提供明确的“背景、目标、约束和风格”。不要给 AI 模糊的指令，而要把它当成一个没有常识但极其聪明的实习生。进阶技巧包括“少样本提示”，即给 AI 提供一两个参考案例；以及“思维链（CoT）”，即在指令中加入“请一步一步思考”，强制 AI 拆解复杂任务的逻辑，从而显著提升回答的准确性。
