Choosing and Fine-Tuning Foundation Models for AI Applications

Building modern AI applications requires more than just calling an API; you must know how to select, evaluate, and customize the right model for your specific needs. This text-based course guides you through the practical decisions involved in deploying foundation models effectively. You will transition from simply using pre-trained models to strategically optimizing them. You will understand how to balance trade-offs like model size, latency, cost, and context window length, while learning the fundamentals of fine-tuning and retrieval-augmented generation. What you will learn: Understand foundational AI model terminology, modalities, and architecture types; Evaluate and select the ideal foundation model based on latency, input length, and cost constraints; Apply prompt engineering and modern Retrieval-Augmented Generation patterns to enhance model outputs; Explore fine-tuning techniques and customization strategies to adapt models to specialized domains; Analyze performance trade-offs to ensure reliable and scalable AI application deployment. The course begins with core terminology and selection frameworks before moving into practical optimization, fine-tuning methodologies, and modern application patterns. You will learn through clear written explanations, structured decision guides, and conceptual code snippets. Designed for software developers, product managers, and technology enthusiasts new to AI engineering, this program requires no advanced machine learning background.
