大语言模型在本质上其实是一个极其复杂的‘概率预测器’，它并不拥有存放事实的数据库，所有的知识都压缩在它预测‘下一个词是什么’的能力里。

大语言模型本质上是一个基于概率的“下一个词预测器”，它并不拥有存储事实的真实数据库。当模型处理训练数据中出现频率极低的“低频事实”（如特定人物的生日或论文标题）时，它感受到的统计压力不足，无法确定准确答案。由于目前的评估体系往往只奖励答对而不奖励“承认不知道”，模型为了获得潜在的得分机会，会倾向于根据概率分布“蒙一个”逻辑自洽的答案，从而产生自信的幻觉。

代码具有极其严密的语法结构，其预测熵值远低于自然语言。在编写代码时，强约束的语法（如 if 后面必须接冒号和缩进）为模型提供了一个天然的“逻辑脚手架”。更重要的是，代码是可执行的。研究表明，将推理任务转化为代码并交给外部解释器运行，能让准确率大幅提升，因为这种确定性的外部反馈弥补了模型概率预测的不确定性。

代码是逻辑密度最高、噪音最低的人类数据，将其加入预训练可以显著提升模型的通用推理和任务分解能力。然而，代码训练与知识密集型任务之间存在竞争关系。如果纯代码数据比例过高，可能会削弱模型在数学推理和常识知识上的表现。目前顶尖的研究倾向于使用带有解释性文字的“结构化推理数据”，以在逻辑严密性和知识丰富度之间取得平衡。

首先，在提示词中明确给予 AI “弃权”的机会，告诉它如果不确定可以回答“不知道”，这能有效调整其激励机制。其次，尝试将复杂的文字任务“代码化”，要求 AI 先写出处理逻辑的伪代码或步骤拆解。最后，尽量引入外部验证环节，例如利用 AI 的代码执行工具来运行计算任务，用物理世界的确定性逻辑来校准模型的概率预测。
