CrewAI
CrewAI is an innovative framework designed to create and manage multi-agent systems. It enables efficient collaboration among AI agents to accomplish various tasks. This platform is useful for automating workflows, enhancing productivity, and integrating advanced AI capabilities into projects.
Key Components of CrewAI
CrewAI consists of several core components that work together to facilitate the operation of AI agents:
Agents: Agents are the individual members of a crew, each with specific roles and skills, such as ‘Researcher’, ‘Writer’, or ‘Customer Support’. These roles help distribute tasks effectively across the team.
Tasks: Tasks are assignments that agents need to complete. Each task includes a description, the assigned agent, and any tools required for execution, allowing for flexible and complex workflows.
Tools: Tools in CrewAI are functions or skills that agents can use to perform actions. These can include web searches, data analysis, and other utilities that enhance agent capabilities. The framework supports both built-in tools and custom tools developed by users.
Processes: Processes manage how tasks are executed by agents, similar to project management in human teams. They ensure that tasks are distributed and completed efficiently according to a predefined strategy.
Crew: A crew is a collaborative group of agents working together to achieve a set of tasks. The crew defines the overall strategy for task execution and agent collaboration.
Getting Started with CrewAI
To begin using CrewAI, you need to set up your environment. This involves installing the CrewAI library and any necessary tool packages. The installation can be done via pip:
pip install crewai
pip install 'crewai[tools]'
After installation, you can create agents and assign them specific roles and tasks. Here’s a detailed example of how to set up agents and tasks, including setting up environment variables and using advanced features:
Example of Setting Up Agents and Tasks
import os
# Set environment variables for API keys and endpoints
os.environ["OPENAI_API_TYPE"] = "azure"
os.environ["OPENAI_API_VERSION"] = "2024-02-15-preview"
os.environ["OPENAI_API_KEY"] = ""
os.environ["AZURE_OPENAI_ENDPOINT"] = ""
os.environ["SERPER_API_KEY"] = ""
# Import necessary libraries
from crewai import Agent, Task, Crew, Process
from langchain_openai import AzureChatOpenAI
from crewai_tools import SerperDevTool
# Setup development and research tools
search_tool = SerperDevTool()
azure_llm = AzureChatOpenAI(
azure_endpoint=os.environ.get("AZURE_OPENAI_ENDPOINT"),
api_key=os.environ.get("OPENAI_API_KEY"),
model="gpt-4o",
)
# Define a Senior Researcher Agent
researcher = Agent(
role='Senior Researcher',
goal='Uncover insights about {topic},
verbose=True,
backstory=(
"Driven by curiosity, you|'re at the forefront of"
"innovation, eager to explore and share knowledge that could change "
"the world. Your expertise helps demystify complex tech topics."
),
tools=[search_tool],
allow_delegation=True,
llm=azure_llm
)
# Define a Writer Agent
writer = Agent(
role='Writer',
goal='Craft engaging blog posts about {topic},
verbose=True,
backstory=(
"Armed with a knack for explaining intricate concepts, you create "
"enticing narratives that educate and engage readers, making new "
"tech accessible to all."
),
tools=[search_tool],
allow_delegation=False,
llm=azure_llm
)
# Define tasks
research_task = Task(
description=(
"Explore and report on the latest developments in {topic}."
"Identify benefits, drawbacks, and market potentials."
),
expected_output='A detailed report with three key sections on emerging trends in {topic}.',
tools=[search_tool],
agent=researcher,
)
write_task = Task(
description=(
"Write an insightful blog post on {topic}, highlighting recent trends and their impacts. "
"Ensure the content is understandable, engaging, and informative."
),
expected_output='A four-paragraph blog post on {topic}, formatted in markdown.',
tools=[search_tool],
agent=writer,
output_file='blog-post.md'
)
# Assemble the crew
tech_crew = Crew(
agents=[researcher, writer],
tasks=[research_task, write_task],
process=Process.sequential,
cache=True,
max_rpm=100,
share_crew=True
)
# Execute the tasks
result = tech_crew.kickoff(inputs={'topic': 'AI in cybersecurity'})
print(result)
Core Concepts of CrewAI Processes
CrewAI’s process management system is designed to facilitate teamwork among agents, allowing them to operate as a cohesive unit. The key features of this system include:
- Task Execution: Processes manage how tasks are executed, ensuring that goals are met effectively.
- Team Coordination: Agents work together systematically, enhancing overall productivity and coherence.
Types of Processes
CrewAI implements several types of processes, each tailored for different task management needs:
- Sequential Process: Tasks are executed in a predefined order. This method ensures that each task is completed before moving on to the next, allowing for a systematic approach to task management.
- Hierarchical Process: This approach simulates a corporate hierarchy, where a designated manager agent oversees task execution. The manager allocates tasks based on agent capabilities, reviews outputs, and validates results, ensuring efficient delegation and management.
- Consensual Process (Planned): A future implementation aimed at promoting collaborative decision-making among agents. This process is not yet available but is in development.
Implementing Processes
To implement a process in CrewAI, developers must specify the desired process type when creating a crew. Here are examples of how to create crews with different processes:
Sequential Process Example
from crewai import Crew
from crewai.process import Process
# Define agents and tasks
my_agents = [...] # List of agents
my_tasks = [...] # List of tasks
# Create a crew with a sequential process
crew = Crew(agents=my_agents, tasks=my_tasks, process=Process.sequential)
Hierarchical Process Example: Without a Manager Agent
Here’s how to define a Hierarchical Process without a manager agent, using CrewAI and Langchain’s ChatOpenAI to manage a team of AI agents with defined roles and goals
from langchain_openai import ChatOpenAI
from crewai import Crew, Process, Agent
# Agents are defined with attributes for backstory, cache, and verbose mode
researcher = Agent(
role='Researcher',
goal='Conduct in-depth analysis',
backstory='Experienced data analyst with a knack for uncovering hidden trends.',
cache=True,
verbose=False,
# tools=[] # This can be optionally specified; defaults to an empty list
)
writer = Agent(
role='Writer',
goal='Create engaging content',
backstory='Creative writer passionate about storytelling in technical domains.',
cache=True,
verbose=False,
# tools=[] # Optionally specify tools; defaults to an empty list
)
# Establishing the crew with a hierarchical process and additional configurations
project_crew = Crew(
tasks=[...], # Tasks to be delegated and executed under the manager's supervision
agents=[researcher, writer],
manager_llm=ChatOpenAI(temperature=0, model="gpt-4"), # Mandatory if manager_agent is not set
process=Process.hierarchical, # Specifies the hierarchical management approach
memory=True, # Enable memory usage for enhanced task execution
manager_agent=None, # Optional: explicitly set a specific agent as manager instead of the manager_llm
)
Source: https://docs.crewai.com/how-to/Hierarchical/#implementing-the-hierarchical-process
In this example:
- The Researcher agent conducts in-depth analysis, and the Writer agent creates engaging content.
- A hierarchical process is used to manage the agents and tasks, with ChatOpenAI as the manager, ensuring efficient task delegation and execution.
- Memory is enabled for enhanced task performance.
Hierarchical Process Example: Without a Manager Agent
Here’s how you can define a research and writing crew with a custom project manager using CrewAI:
import os
from crewai import Agent, Task, Crew, Process
# Define your agents
researcher = Agent(
role="Researcher",
goal="Conduct thorough research and analysis on AI and AI agents",
backstory="You're an expert researcher, specialized in technology, software engineering, AI, and startups. You work as a freelancer and are currently researching for a new client.",
allow_delegation=False,
)
writer = Agent(
role="Senior Writer",
goal="Create compelling content about AI and AI agents",
backstory="You're a senior writer, specialized in technology, software engineering, AI, and startups. You work as a freelancer and are currently writing content for a new client.",
allow_delegation=False,
)
# Define your task
task = Task(
description="Generate a list of 5 interesting ideas for an article, then write one captivating paragraph for each idea that showcases the potential of a full article on this topic. Return the list of ideas with their paragraphs and your notes.",
expected_output="5 bullet points, each with a paragraph and accompanying notes.",
)
# Define the manager agent
manager = Agent(
role="Project Manager",
goal="Efficiently manage the crew and ensure high-quality task completion",
backstory="You're an experienced project manager, skilled in overseeing complex projects and guiding teams to success. Your role is to coordinate the efforts of the crew members, ensuring that each task is completed on time and to the highest standard.",
allow_delegation=True,
)
# Instantiate your crew with a custom manager
crew = Crew(
agents=[researcher, writer],
tasks=[task],
manager_agent=manager,
process=Process.hierarchical,
)
# Start the crew's work
result = crew.kickoff()
Source: https://docs.crewai.com/how-to/Your-Own-Manager-Agent/
In this example:
- Researcher and Writer agents are defined with specific roles and goals, each specialized in AI and technology content.
- A Task is created to generate article ideas and write paragraphs for each.
- A Manager Agent is introduced to oversee and ensure the completion of tasks to high standards.
- The Crew is instantiated with the agents, tasks, and manager, set to follow a hierarchical process.
- Finally, the crew’s work is started, and the result is printed.
- Task Delegation: In the hierarchical process, a manager agent assigns tasks based on the strengths and roles of each agent.
- Result Validation: The manager evaluates the outcomes of tasks to ensure they meet established standards.
- Asynchronous Execution: Tasks can be executed concurrently, enhancing the efficiency of the crew.
- Human Input Review: An optional feature allows human oversight of task outputs before finalization, ensuring quality control.
- Output Customization: Tasks can generate outputs in various formats, such as JSON or Pydantic models, providing flexibility in data handling.
