The transformational world of AI is evolving, and tools like n8n are paving the way for seamless integration of local language models. Have you heard about Ollama? It's a neat solution that helps you run Large Language Models (LLMs) on your own hardware, giving you control over privacy & cost. Let's dive into the juicy details about setting up Ollama with n8n, and trust me, it’s going to boost your workflow automation game significantly!
What is n8n?
n8n is an open-source workflow automation tool that provides the capability to connect over 422 apps and services with ease. Whether you want to automate repetitive tasks, create custom integrations, or simply streamline your business processes, n8n can handle it all. With its visual interface, you can build complex workflows by just dragging & dropping different nodes.
What is Ollama?
On the flip side, we have Ollama. This tool allows you to run various LLMs locally, freeing you from the clutches of cloud-based hoops. It simplifies the process of downloading & managing these models, significantly reducing the operational costs you might face using cloud services. Want to keep your data private? Ollama has you covered! Using Ollama gives you the ability to tailor the model's behavior based on your specific needs.
Why Use Ollama with n8n?
Integrating Ollama with n8n opens up a world of possibilities by allowing you to leverage LLMs in your workflows. The combination not only helps in task automation but also enhances your application's intelligence capacity by enabling conversational interfaces, automatic responses, and more!
Prerequisites for Setup
Before diving into the setup, there are a few prerequisites you will need:
Ollama installed on your machine.
n8n node to facilitate the connection.
Basic knowledge of how to operate both tools.
To get started, you can either run Ollama locally or as a self-hosted solution. The seamless integration will allow you to connect Ollama with various other services and apps using n8n.
Step-by-Step: Setting Up Ollama with n8n
Let’s break down the setup into digestible steps. This way, you won’t miss a beat!

You’ve got to ensure that the Ollama server is up & running correctly before validating your settings in n8n.
Step 2: Install n8n
The next crucial step is getting n8n set up. You can run n8n either on your desktop or server. n8n’s official site provides options for installation using Docker, npm, or even directly on your system. Choose what's best for you:
Docker is often easier & more consistent across different environments.
npm is perfect if you enjoy the Node.js ecosystem.
Desktop should appeal more to those who prefer a GUI experience.
Step 3: Configure Ollama Node in n8n
Once you have both Ollama and n8n running, the next step is to connect them.
Open your n8n dashboard.
Create a new workflow and add the Ollama node to your canvas. You can search for it using the search bar.
Configure the Ollama node with the appropriate settings:
Base URL: Generally, this is
1
http://localhost:11434
. This is the default port that the Ollama runs on. Make sure this value matches the port you have Ollama running on.
Ensure you enter the right credentials if necessary. Refer to the Ollama credentials documentation if you need guidance on that.
Where Do I Get Credentials?
You can obtain credentials from the Ollama dashboard or directly from your configuration files where you installed Ollama. These credentials will often be linked to the API interactions you intend to set up with n8n.
Step 4: Building Your Workflow
Once you have your Ollama node configured within n8n, it’s time to start building your workflow! Here’s how:
Drag & Drop Nodes: Use other integrated nodes like HTTP Request, Webhook, or anything else that aligns with your workflow.
Input Configuration: Make sure to leverage input fields where needed to tailor responses from your LLM.
Output Flow: Once Ollama generates responses, utilize other nodes to send them back through emails, to your Slack channel, or store in a database.
Before going full throttle, always test the setup. Use sample data & ensure that the responses returned from Ollama are valid and align with expected outputs. Adjust the settings accordingly for optimal results!
Real-World Applications

Double-check your Ollama server is running properly.
Verify the n8n settings & ensure you’ve configured the node correctly.
Ensure there are no network or firewall restrictions that may block connections.
