AI Summary

Video Summary

Introduction

  • The video introduces the integration of Open Web UI into the local AI starter kit, allowing users to chat with their n8n workflows directly.
  • Open Web UI is an open-source interface similar to ChatGPT, which can be used to chat with large language models running with Olama.
  • It features functions and pipelines for implementing custom functionality, such as chatting with your own agents and API endpoints.

Local AI Starter Kit Overview

  • The local AI starter kit, developed by the n8n team, includes a Docker compose file that combines containers for various services to host everything locally.
  • Services included are n8n for workflow automations, Olama for large language models, Quadrant for vector databases, and PostgreSQL for SQL databases.
  • The repository for the starter kit has been forked and updated to include Open Web UI.

Setting Up the Local AI Package

  • Detailed instructions are provided for setting up the local AI package, including a basic AI agent workflow in n8n and integrating it with Open Web UI.
  • The setup process involves cloning the repository, configuring environment variables, and running Docker compose commands.
  • The Docker compose file has been updated to include a container for Open Web UI.

n8n Workflow and Open Web UI Integration

  • A demonstration workflow in n8n combines services like Quadrant, PostgreSQL, n8n, and Olama to create a simple AI agent.
  • The workflow starts with a webhook that receives user input and generates a response using Olama.
  • Credentials for connecting n8n to services like Olama and Quadrant are set up within the n8n interface.
  • The workflow responds to the webhook with the output from the AI agent.

Open Web UI Customization

  • Open Web UI allows for the creation of custom functions to interact with agents and API endpoints.
  • The video demonstrates how to set up a custom function for n8n integration using Python scripts.
  • Parameters such as the n8n webhook URL and bearer token can be customized within Open Web UI.
  • The function makes an HTTP request to the n8n webhook with the user’s input and returns the AI agent’s response.

Voice Interaction

  • Open Web UI supports voice interaction, allowing users to talk to their n8n AI agents using a microphone.

Conclusion

  • The video concludes with the successful integration of Open Web UI into the local AI starter kit, enabling chat with workflow agents.
  • Viewers are encouraged to suggest future extensions for the local AI stack.
