Course Description

Are you looking to build and run customized large language models (LLMs) right on your own system, without depending on cloud solutions? Do you want to maintain privacy while leveraging powerful models similar to ChatGPT? If you're a developer, data scientist, or an AI enthusiast wanting to create local LLM applications, this course is for you!

This hands-on course will take you from beginner to expert in using Ollama, a platform designed for running local LLM models. You’ll learn how to set up and customize models, create a ChatGPT-like interface, and build private applications using Python—all from the comfort of your own system.

In this course, you will:

  • Install and customize Ollama for local LLM model execution

  • Master all command-line tools to effectively control Ollama

  • Run a ChatGPT-like interface on your system using Open WebUI

  • Integrate various models (text, vision, code generation) and even create your own custom models

  • Build Python applications using Ollama and its library, with OpenAI API compatibility

  • Leverage LangChain to enhance your LLM capabilities, including Retrieval-Augmented Generation (RAG)

  • Deploy tools and agents to interact with Ollama models in both terminal and LangChain environments

Why is this course important? In a world where privacy is becoming a greater concern, running LLMs locally ensures your data stays on your machine. This not only improves data security but also allows you to customize models for specialized tasks without external dependencies.

You’ll complete activities like building custom models, setting up Docker for web interfaces, and developing RAG applications that retrieve and respond to user queries based on your data. Each section is packed with real-world applications to give you the experience and confidence to build your own local LLM solutions.

Why this course? I specialize in making advanced AI topics practical and accessible, with hands-on projects that ensure you’re not just learning but actually building real solutions. Whether you’re new to LLMs or looking to deepen your skills, this course will equip you with everything you need.

I was a bit confused about where to start with AI as a senior Java fullstack developer but this course is clearely what I needed to start off my journey with AI powered apllications. Can't wait to see what I can do with Ollama tool.

By Michael Nierla on 5/14/2026

I really liked the course. The information and the practical exercises are helpful and interesting. However, the roleplays were annoying and not fully solvable for me. Especially the last one was impossible to do in time. After the 10minutes I had not even started with topic 3 of 5.

By Daniele Morano on 1/2/2026

Excellent course, the explanations are clear and straightforward, explaining step by step what the objectives are and how to achieve them. It is only a basic course, but it lays a solid foundation for continuing with more advanced courses.

By Anonymized User on 11/21/2025

This course was excellent! I joined to explore new skills, and it really helped me understand the fundamentals. The framework of the course was engaging — not boring at all. It kept me excited throughout, with less theory and more practical, hands-on learning, which suits me perfectly. One challenge I faced was that some libraries have moved to different packages since the recorded videos are a bit old. This caused minor issues, but I managed to figure them out on my own and complete the tasks successfully.

While the course covers the general material, I found the instructor’s instructions to be very vague. The lessons mostly followed a script without explaining the reasoning behind each step or what the commands actually do. There was little discussion about “why” things are done a certain way, and almost no real troubleshooting when things didn’t work as expected. This course could be much better if the instructor took time to explain the concepts, demonstrated troubleshooting techniques, and connected the steps to real-world scenarios, rather than just reading through a preset list of commands.

By Isuru Siriwardana on 4/6/2025

The course is comprehensive and provides all the necessary information required to start diving deep into the AI world. I recommend it as a very good place for any one to start their journey in learning LLM based application development.

By Damian Corbalan on 2/25/2025

Es un vistazo interesante a Ollama y sus capacidades. En mi opinión estaría bueno que use openwebui en todo el curso no solo en la primera parte. Se pierde un poco la idea o el sentido de instalar todo si después no se termina usando. Ademas, ya que se instalo Docker, podría usar Ollama desde un contenedor en lugar de hacer la instalacion exclusiva sobre el sistema. En los docs de Ollama en docker incluso muestran como correrlo para que use nuestras GPU, por lo que no le veo el sentido a instalaciones tan diferentes que separan un poco de la linea del curso que de por si es interesante, claro y bien explicado.

By Siddhesh Wani on 2/5/2025

The course content was well-structured and easy to follow, making complex concepts accessible even for beginners. The practical examples and hands-on exercises were particularly helpful in solidifying my understanding. The instructors were knowledgeable and provided clear explanations throughout. I now feel confident in setting up and utilizing Ollama for my local LLM projects. Highly recommended for anyone looking to get started with LLMs!

By Tamas G. on 1/13/2025

The course is straightforward, practical, short! and to the point. It is one of the best courses I have ever taken on Udemy. You will not get lost in unnecessary information but learn everything that is needed for a quick start. Thank you! I wish there were more courses like this.

By Veerendra Kumar Shakya on 12/2/2024

only the basics are covered, but i was looking for more advance for real world, application development.
