Introduction to Open-Source LLMs: Selection, Setup, and Local Deployment

Proprietary language models offer great power, but open-source alternatives provide unmatched control, privacy, and customization. Understanding how to navigate the rapidly growing ecosystem of open-source models is now an essential skill. This text-based course guides you through the foundational concepts of open-source Large Language Models (LLMs). You will learn how to evaluate different models, set them up on your own hardware, and integrate them into your workflows without relying on third-party APIs. In this course, you will: 1. Understand the core differences between open-source and closed-source model architectures. 2. Evaluate and select the right open-source model for your specific use case using standard benchmarks. 3. Configure and run models locally using modern tools like Ollama and Hugging Face libraries. 4. Apply basic prompt engineering techniques optimized for open-source model behaviors. 5. Explore the fundamentals of retrieval-augmented generation (RAG) using local vector stores. 6. Learn the basics of privacy-focused deployment and resource optimization techniques. You will start with key terminology and architectural foundations before moving on to practical setup guides, model evaluations, and step-by-step written exercises to run your first local model. This course is designed for beginners, developers, and technology-curious individuals, with no prior experience with machine learning or natural language processing required.
