LLM
系统
目前我们构建的系统均按照预设流程执行操作。
LLM
最具突破性的发展方向在于其自主决
策能力。这类能够自主规划行动及其序列的系统被称为智能体（
agent
），其核心在于利用
语言模型自主制定行动决策。
智能体系统整合了我们已掌握的各项技术（包括模型输入
/
输出、链式架构和记忆模块），
并通过两大核心组件实现功能扩展：
•
工具
（
tool
）：赋予智能体完成自身无法独立处理的任务的能力。
•
智能体类型
（
agent type
）：规划行动及工具使用策略的决策框架。
相较于传统链式架构，智能体展现出更强大的行为逻辑：可自主创建目标实现路径，具备
自我纠错能力，并能通过工具与现实世界进行交互。这些特性使得智能体能够完成超越单
个
LLM
能力边界的复杂任务。
例如，
LLM
在数学问题上的表现一直为人诟病，经常连简单的数学任务都无法正确解
决

。但当我们为其配备计算器工具时，它们的数学能力便得到显著提升。如图

所示，
智能体的核心原理在于不仅利用
LLM
理解用户查询，更赋予其自主选择调用工具的能力。
