Hello World to CrewAI
Previously we tried agent programming framework LangGraph. In this post, let’s say Hello to CrewAI. According to CrewAI website, it is “Framework for orchestrating role-playing, autonomous AI agents. By fostering collaborative intelligence, CrewAI empowers agents to work together seamlessly, tackling complex tasks.”
TLDR: for sequential tasks, CrewAI is more intuitive to setup, especially on task, passing data between agents.
CrewAI Concepts
Steps
We are following this sample.
Setup LLM
import os
from dotenv import load_dotenv
load_dotenv()
from langchain_openai import AzureChatOpenAI
# Choose the LLM that will drive the agent
llm = AzureChatOpenAI(azure_deployment=os.getenv("AZURE_OPENAI_DEPLOYMENT_NAME"), temperature=0, streaming=True)Setup search tool
