Prompt Engineering for Token Limits and Context Windows

Every time you interact with a Large Language Model (LLM), behind-the-scenes mechanics dictate how much information the model can process and remember. Understanding how tokens and context windows function is the key to writing efficient, cost-effective, and powerful prompts. This course guides you from the absolute basics of LLM architecture to practical prompt optimization. You will learn how to structure your prompts to fit within strict constraints, maintain coherent multi-turn conversations, and avoid the common pitfalls of stateless AI memory. What you'll learn: - Understand the fundamental concept of tokens, how text is converted to numerical representations, and how to estimate token usage. - Analyze the mechanics of context windows and how LLMs maintain the illusion of memory in conversational threads. - Apply practical prompt engineering techniques to compress prompts and maximize information density. - Manage API costs and performance by designing token-efficient prompt structures. - Explore modern strategies like Retrieval-Augmented Generation (RAG) to handle information that exceeds standard token limits. You will start by exploring core definitions and tokenization basics before moving on to practical written exercises that demonstrate how to manage context drift. Through structured reading and step-by-step conceptual breakdowns, you will learn to write prompts that deliver high-quality results within any model's technical boundaries. This course is designed for beginners looking to improve their prompt engineering skills, with no prior programming or computer science experience required.
