从技术角度来说,AI智能体是一个旨在代表用户或其他程序自主或半自主执行任务的软件实体。这些智能体利用人工智能做出决策、采取行动,并与它们的环境或其他系统进行交互。智能体的一些关键特性如下:

  1. 自主性:AI智能体在不需要持续的人类干预下运行。一旦它们被赋予目标,它们可以独立执行任务。

  2. 决策制定:它们使用算法、规则和AI模型根据它们的感知和目标做出决策。这包括评估不同的选项并选择最佳的行动方案。

  3. 学习:许多AI智能体结合了机器学习技术来随着时间的推移提高它们的表现。它们可以从过去的经验中学习并适应新的情况。

  4. 交互:AI智能体可以与用户、其他智能体或系统进行通信和协作。这种交互可以涉及自然语言处理、发送和接收数据,或执行协调任务。

  5. 专业化:AI智能体可以为特定任务或领域专门化。例如,一些智能体可能被设计用于浏览网页,而其他智能体可能处理数据库交互、执行复杂计算或生成图像。

  6. 目标导向:AI智能体通常被编程具有特定的目标或目的。它们通过一系列行动和决策来实现这些目标。

AI智能体是强大的工具,可以自动化和增强从简单的重复性任务到复杂的问题解决场景的广泛活动,使它们在各种应用和行业中变得非常宝贵。

想象一下,将所有上述概念集成在一起,并且所有这些都协同工作以实现预定义的目标以获得期望的结果。这些任务可以以顺序或层次结构的过程执行,所有智能体像一个协调的团队一样工作。这种强大的协作可以彻底改变我们处理复杂问题的方式,使流程更加高效,结果更加有效。这就是CrewAI框架发挥作用的地方。

什么是CrewAI?

CrewAI是一个尖端的框架,用于协调角色扮演、自主AI智能体。通过培养协作智能,CrewAI使智能体能够无缝协作,共同解决复杂任务。

CrewAI的核心概念

  1. 智能体(Agent):这些是独立编程以执行任务、做出决策和与其他智能体通信的单元。它们可以使用工具,这些工具可以是简单的搜索功能或涉及其他链、API等的复杂集成。

  2. 任务(Task):任务是AI智能体需要完成的指派或工作。它们可以包括额外信息,比如哪个智能体应该做以及它们可能需要哪些工具。

  3. 一个团队(Crew)是具有特定角色的智能体团队,它们共同实现一个共同目标。组建团队的过程包括组装智能体、定义它们的任务和建立任务执行的顺序。

本文旨在通过一个CrewAI示例,全面概述CrewAI平台的组成部分。

什么是Ollama?

Ollama是一个开源应用程序,允许您在MacOS、Linux和Windows上通过命令行界面本地运行、创建和共享大型语言模型。

Ollama可以直接访问其库中直接可用的广泛LLMs,可以使用单个命令下载。下载后,您可以通过单个命令执行开始使用它。这对于围绕终端窗口工作负载的用户来说非常有帮助。如果他们被困在某个地方,他们可以在不切换到另一个浏览器窗口的情况下获得答案。

Ollama的特点和优势

以下是Ollama成为您工具箱中必备品的原因:

  • 简单性:Ollama提供了一个直接的设置过程。您不需要机器学习博士学位就能让它运行起来。

  • 成本效益:本地运行模型意味着您不会累积云成本。您的钱包会感谢您。

  • 隐私:使用Ollama,所有数据处理都发生在您的本地机器上。这对于用户隐私来说是一个巨大的胜利。

  • 多功能性:Ollama不仅适用于Python爱好者。它的灵活性允许它在各种应用程序中使用,包括Web开发。


使用Ollama选择LLM

默认情况下,Openai模型被用作CrewAI中的LLM。为了在CrewAI团队中获得最佳性能,请考虑使用OpenAI的GPT-4或稍微便宜的GPT-3.5。这些模型是您智能体的支柱,显著影响它们的能力。

但在这里,我们将使用Meta Llama 3,迄今为止最强大的公开可用LLM。Meta Inc.开发的Meta Llama 3是一系列新的最佳实践模型,有8B和70B参数大小(预训练或指令调整)。

Llama 3指令调整模型经过微调和优化,用于对话/聊天用例,在常见基准测试中的表现超过了许多可用的开源聊天模型。

代码实现

安装所需的依赖项

ollama (Windows)

前往Ollama官网下载.exe文件:https://ollama.com

下载并安装Ollama至Windows系统。您可以选择使用默认的模型保存路径,通常位于:C:\Users\your_user\.ollama。

如果程序没有启动,可以在Windows程序中搜索它并从那里启动。

然后在命令提示符中下载llama3模型

ollama run llama3

Crewai

!pip install crewai==0.28.8 crewai_tools==0.1.6 langchain_community==0.0.29

设置LLM为Llama3

在项目目录中创建一个类似于以下的ModelFile。

FROM llama3
# Set parameters
PARAMETER temperature 0.8PARAMETER stop Result
# Sets a custom system message to specify the behavior of the chat assistant
# Leaving it blank for now.

In this article, we will conduct a comparative study of LangGraph, Autogen, and Crewai, three prominent technologies used for building multi-agent systems.
**Introduction**---------------
A multi-agent system (MAS) is defined as a complex system consisting of multiple intelligent agents interacting with each other to achieve a common goal. The importance of MAS lies in its ability to model real-world systems where multiple autonomous entities interact and adapt to changing environments. LangGraph, Autogen, and Crewai are three technologies that have gained significant attention in the field of multi-agent system building.
LangGraph, Autogen, and Crewai are all designed to facilitate the development of multi-agent systems by providing efficient ways to represent, reason with, and generate complex knowledge structures. While each technology has its strengths and weaknesses, a comparative study reveals that LangGraph is well-suited for natural language processing (NLP) tasks, Autogen excels in machine learning (ML) and data generation, and Crewai shines in rule-based systems and knowledge representation.
**Comparative Analysis of LangGraph, Autogen, and Crewai**--------------------------------------------------------
### LangGraph
LangGraph is a novel language designed specifically for describing complex systems. Its natural language processing capabilities make it an ideal choice for tasks that require semantic parsing, such as question answering and text summarization. Advantages of using LangGraph include ease of integration with existing NLP frameworks and scalability. However, its limitations are reflected in its inability to handle complex scenarios.
### Autogen
Autogen is a machine learning framework designed to generate realistic data for training ML models efficiently. Its data generation capabilities make it suitable for tasks such as data augmentation, text classification, and image recognition. Advantages of using Autogen include efficient data processing and the ability to generate realistic data. However, Autogen requires extensive data annotation and may not perform well in noisy environments.
### Crewai
Crewai is a rule-based system designed to facilitate knowledge representation and reasoning. Its scalability makes it suitable for large-scale applications, such as expert systems, decision support systems, and intelligent agents. Advantages of using Crewai include its ability to represent complex knowledge structures and scalability. However, Crewai requires manual rule development and may not be suitable for complex scenarios.
**Key Takeaways and Recommendations**----------------------------------------
In conclusion, LangGraph, Autogen, and Crewai are three technologies that offer distinct strengths in building multi-agent systems. A key takeaway is that each technology has its unique advantages and disadvantages. The choice of technology depends on the specific needs of the application, such as NLP tasks for LangGraph or data generation for Autogen.
Recommendations include:
* Use LangGraph for NLP tasks such as question answering and text summarization.* Utilize Autogen for machine learning tasks that require efficient data processing and generation of realistic data.* Apply Crewai for rule-based systems and knowledge representation that require scalability and complex reasoning.
**Call to Action**-------------------
The next multi-agent system project requires careful consideration of the choice of technology. LangGraph, Autogen, and Crewai offer unique advantages in building successful MASs. Start exploring these technologies today to unlock their potential and reap the rewards of developing cutting-edge multi-agent systems!
