crewAI

crewAI

比如一个项目有多个任务，先搜索，然后再生成，搜索需要使用gpt4或搜索引擎，生成使用gpt3.5。通过crewAI定义多agent，多task实现。

crewAI源码很简单，不涉及AI功能。

Usage

pip install crewai
pip install duckduckgo-search

import os
from crewai import Agent, Task, Crew, Process

os.environ["OPENAI_API_KEY"] = "YOUR KEY"

from langchain.tools import DuckDuckGoSearchRun
search_tool = DuckDuckGoSearchRun()

# 定义一个拥有 DuckDuckGoSearchRun 搜索归纳功能的 Agent
researcher = Agent(

# 任务二，基于任务一的归纳，写一篇博客
task2 = Task(
  description="""Using the insights provided, develop an engaging blog
  post that highlights the most significant AI advancements.
  Your post should be informative yet accessible, catering to a tech-savvy audience.
  Make it sound cool, avoid complex words so it doesn't sound like AI.

# 定义
crew = Crew(
  agents=[researcher, writer],
  tasks=[task1, task2],
  verbose=2, # You can set it to 1 or 2 to different logging levels
)

# 执行
