The field of Large Language Models (LLMs) is evolving rapidly, and the ability to build robust, scalable, and production-ready LLM applications has become a critical skill for developers and AI practitioners. Hamza Farooq’s groundbreaking course, Building LLM Applications from Scratch, has now been open-sourced, offering learners worldwide an unparalleled opportunity to master these skills—for free!

Why This Course Stands Out

Unlike many other courses that rely on pre-built frameworks like LangChain or LlamaIndex, this course delves into the fundamentals of LLM application development. It equips learners with the knowledge to build solutions from first principles, focusing on essential concepts such as:

  • Retrieval-Augmented Generation (RAG): Learn advanced retrieval strategies, chunking methods, and embedding customisation.
  • Custom Embeddings: Understand how to optimise embeddings for specific use cases.
  • Optimised Inference Techniques: Explore fine-tuning, quantisation, and other performance enhancements.
  • AI Agents: Develop intelligent agents capable of handling complex tasks autonomously.

By mastering these core principles, participants can create applications that are not only functional but also scalable and reliable for real-world deployment.

Global Impact and Reach

Since its launch, this course has been taught at prestigious institutions such as Stanford University and UCLA’s Anderson School of Management. It has reached over 1,500 learners across 30+ countries, making it a truly global educational initiative.

What You’ll Gain

Here’s what makes this course a must-learn for anyone interested in LLM application development:

  • Comprehensive Understanding: Gain an end-to-end perspective on building LLM-powered solutions.
  • Deep Dive into RAG: Master tailored retrieval strategies, optimal chunking techniques, and embedding refinement.
  • Deployment Expertise: Learn fine-tuning methods, model quantisation techniques, and strategies for optimising inference performance.
  • Responsible AI Practices: Understand how to implement guardrails for reliability and trustworthiness in real-world applications.
