Part 1 – Foundations (Day 1–2 | ~6 hrs)

Goal: Understand Generative AI, Foundation Models, and LLMs. Think of this as setting the stage for your AI journey. We need to know the basics before we start building!

First, let's define some key terms. Generative AI refers to AI models that can generate new content, such as text, images, or music. Foundation Models are large AI models trained on vast amounts of data, serving as a base for various applications. Large Language Models (LLMs) are a type of foundation model specifically designed for natural language processing. Grasping these core concepts is crucial. You will be able to utilize Generative AI and Foundation Models to enhance your agents' capabilities. Without this understanding, the more complex parts of agent building can feel overwhelming. So, before rushing into the code, let’s make sure we have a solid conceptual grounding. This foundational knowledge is the bedrock upon which we’ll construct your AI agent expertise.

Here are some resources to get you started:

✅ Mini-task: Write a short note (1–2 paragraphs) comparing Generative AI vs LLMs. This will help solidify your understanding. This mini-task isn’t just busywork; it’s about internalizing the differences. By articulating the distinctions between Generative AI and LLMs, you reinforce your learning and prepare for more advanced topics. Understanding the nuances of each concept is essential for making informed decisions when designing and implementing AI agents. Think of it as laying the intellectual groundwork for the exciting projects ahead. It is an investment that pays dividends as you progress through this learning path.

Part 2 – Meet the Agents (Day 3–4 | ~7 hrs)

Goal: Understand what AI Agents are and how they work. Now that we know the basics of AI and LLMs, it’s time to focus on the stars of our show: AI Agents. An AI Agent is an intelligent system that can perceive its environment, make decisions, and take actions to achieve specific goals. They're like little digital helpers that can automate tasks, answer questions, and even create new content. The power of AI Agents lies in their ability to interact with the world and make decisions autonomously. The beauty of AI Agents is their ability to automate tasks and solve problems without constant human intervention. This means understanding their components, how they’re built, and the principles that guide their operation is essential.

In this part, we’ll explore what AI Agents are, how they function, and why they are transforming various industries. We will discuss how AI Agents make decisions and what core components are necessary for their creation. Understanding their mechanics will empower you to design and build effective agents. By the end of this part, you will know exactly what AI Agents are and why they are the future of intelligent systems. This is a crucial step towards building your own agents.

Here are some resources to get you acquainted with AI Agents:

✅ Mini-task: Build a Hello World AI Agent in Python using LangChain. Time to get your hands dirty! This is where you'll write your first lines of code to create an AI Agent. Building a “Hello World” AI agent might sound simple, but it’s a critical step. It’s about applying the theory we've discussed to practical coding. By creating this basic agent, you’re familiarizing yourself with the fundamental components and the workflow of building an agent. It’s a hands-on way to ensure you truly grasp the concept of how agents operate. Plus, you’ll gain confidence as you see your agent come to life.
