LLM Fine-Tuning and Application Development with H2O

Harnessing the power of custom Large Language Models (LLMs) no longer requires a massive team of research scientists. With open-source tools like H2O, you can align, fine-tune, and deploy highly specialized generative AI models tailored to your specific domain. This comprehensive text-based course guides you through the entire lifecycle of custom LLM development, helping you transition from a user of generic APIs to a creator of specialized language technologies. By reading through this course, you will progress from foundational concepts of transformer architectures to practical fine-tuning strategies, evaluation methodologies, and modern retrieval-augmented generation setups. You will gain a deep conceptual and practical understanding of how to adapt pre-trained models to perform niche tasks with high accuracy. What you'll learn: - Understand the core architecture of large language models and key terminology. - Fine-tune open-source LLMs using H2O tools for specific domain tasks. - Implement prompt engineering patterns to guide model outputs reliably. - Configure Retrieval-Augmented Generation (RAG) to connect models to custom knowledge bases. - Evaluate model performance using quantitative metrics and alignment techniques. - Deploy customized models to production environments for real-world integration. You will start by exploring foundational LLM concepts, tokenization, and data preparation workflows. From there, you will read through step-by-step guides on parameter-efficient fine-tuning, evaluation, and setting up vector databases to build complete, context-aware AI applications. This course is designed for aspiring AI developers, data practitioners, and technology enthusiasts who want to build custom language models. No advanced machine learning background is required to begin, making it accessible for anyone ready to learn through clear explanations and structured code walk-throughs.
