# 第一章 智能体范式革命

> “AI 的未来不仅是聊天机器人回答问题，而是智能体采取行动解决真实问题。”

本章建立智能体的宏观认知框架。你将学习从静态LLM向动态自主智能体的演进，理解支撑智能体运行的核心理论模型(PEAS、POMDP)，拆解四大核心组件(大脑、感知、行动、记忆)，以及掌握从L1到L5的认知层级分类。

## 学习目标

完成本章后，你将能够：

1. **理解** 智能体与LLM的本质区别
2. **掌握** 智能体的核心理论模型与四大核心组件
3. **评估** 智能体的认知层级与能力边界
4. **应用** 智能体工作流范式优化系统设计

## 章节地图

本章按照“范式转移 → 理论基础 → 核心组件 → 能力分层 → 工作流模式”的顺序展开，先回答“什么是智能体”，再回答“它为什么成立、由什么组成，以及如何落到工程设计”。

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://yeasy.gitbook.io/agentic_ai_guide/di-yi-bu-fen-dan-ti-zhi-neng-jia-gou/01_paradigm.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
