The Power of CrewAI with Local LLMs
Large Language Models (LLMs) have opened the door to powerful task automation, but not everyone wants to rely on cloud-based services. That’s where CrewAI shines — allowing you to build multi-agent workflows while connecting to local models for improved privacy, lower latency, and cost savings.
Using CrewAI with locally hosted LLMs such as Ollama or LM Studio gives you full control over your AI workflows. You can design agents that specialize in different roles and chain them together to execute complex processes from start to finish — all on your own machine.
Why use CrewAI with Local Models?
- Privacy & Control– Keep all data on your local machine.
- Offline Capability – Work without an internet connection.
- Reduced Cost – No recurring cloud LLM API fees.
- Customization – Fine-tune models or swap them easily.
Example: Multi-Agent Workflow
Here’s a simple example of using CrewAI with a local model for task automation:
- Research Agent – Gathers and summarizes information.
- Planning Agent – Breaks tasks into actionable steps.
- Execution Agent – Performs structured actions, such as generating reports or code.
Setting It Up
Step 1: Install Ollama (or another local LLM runtime):
brew install ollama
Make sure ollama is running.
Step 2: Then pull the model you want to use:
ollama pull mistral
Step 3: Install CrewAI
pip install crewai
Step 4: Connect CrewAI to your local machine
from langchain_community.llms import Ollama
from crewai import Agent, Task, Crew, Process
llm = Ollama(model="mistral")
research_agent = Agent(
role="Research Analyst",
goal="Research topics and provide summaries",
backstory="An AI that gathers and organizes knowledge.",
llm=llm
)
task = Task(
description="Research CrewAI's features and summarize them in bullet points.",
expected_output="A concise bullet point list.",
agent=research_agent
)
crew = Crew(
agents=[research_agent],
tasks=[task],
process=Process.sequential
)
print(crew.kickoff())
