Day 1 – Introduction to Generative AI Lesson

Lesson Overview

Generative AI is the branch of artificial intelligence focused on creating new content—text, images, audio, and video—by learning from existing data. Unlike earlier AI systems that analyzed or classified information, generative AI models actually produce new content that mimics the examples they were trained on. This shift has rapidly changed the landscape of digital creativity and productivity, making powerful tools like ChatGPT, Midjourney, and others available to anyone.

This lesson explains how generative AI became widely adopted, starting with the release of ChatGPT by OpenAI in 2022. Tools like Microsoft Copilot, Google Gemini, Anthropic’s Claude, Meta AI, and Grok from X (Twitter) are discussed, highlighting how quickly the space has expanded. You’ll discover that while many technology companies race to develop their own models, understanding the basic principles behind one tool gives you the foundation to use others.

We’ll also cover the two major forms of generative AI: large language models (for text) and diffusion models (for images, audio, and more). Examples from both categories are introduced, and you’ll get a preview of multimedia applications, from realistic avatars to music generation. The lesson also briefly introduces the concept of Artificial General Intelligence (AGI), a long-term goal in AI development.

By the end of this introduction, you’ll have a mental map of the major tools, ideas, and terms that shape today’s generative AI ecosystem.

Who This Is For

Whether you’re new to AI or have some experience, this lesson is designed for anyone curious about the current state of generative AI. This includes:

• Educators who want to understand new creative technologies
• Business professionals interested in AI-powered content creation
• Content creators exploring new media production tools
• Students and lifelong learners starting their AI journey
• Product managers or team leaders tasked with evaluating AI solutions
• Anyone curious about how and why AI is suddenly everywhere

Where This Fits in a Workflow

Understanding generative AI is often the first step for teams and individuals before applying these tools to their projects or workflows. By knowing the range of available models and how they differ, you’ll have context for picking the right tool—whether you’re hoping to draft content, create images, generate videos, or automate basic creative tasks.

For example, a marketing team might use a large language model to generate ad copy and a diffusion model like Midjourney to design social visuals. Creators can script dialogue with ChatGPT and transform it into lifelike audio using Eleven Labs. This foundational knowledge ensures you can choose the right generative AI tool at each step of a creative or business process.

Technical & Workflow Benefits

Before generative AI, producing new content required extensive manual effort—writing out every sentence, editing images by hand, or composing music note-by-note. With generative AI, those workloads are massively reduced. For instance, drafting an article with ChatGPT can take minutes instead of hours, and creating a custom image with Midjourney removes the need for graphic design expertise.

This new approach also improves creative speed and enables rapid iteration. You can generate multiple versions of a concept, refine through feedback, and streamline production. In contexts like product development, marketing, or teaching, this means more content with fewer resources and faster turnaround. Once you learn the basics of one model, those skills translate quickly to others, making you more adaptive and future-proof as tools continue to evolve.

Practice Exercise

Pick a topic or simple creative prompt relevant to your needs (for example, “Describe a futuristic city,” or “Generate a logo idea for a sustainable coffee shop”).

1. Using any free generative AI tool listed above (such as ChatGPT or Copilot for text, or try a public demo from DALL-E or Midjourney), enter your prompt and review the result.
2. Experiment by rephrasing your prompt or trying a different tool from the list.
3. Compare the outputs: Which tool or model best matched your creative intent? What differences did you notice in the style or quality of the results?

Reflect on how generative AI could make a process you care about faster or easier.

Course Context Recap

This lesson launched your 14-Day AI Boot Camp by introducing the fundamentals of generative AI, key models, and major platforms. With this overview, you now have the background needed to see how specific AI models—like large language models (LLMs)—are built and used. Coming up, you’ll learn how these models work under the hood, how to get the most from them, and how to apply them for real creative or business value. Continue through the course to deepen your skills and discover the best ways to use generative AI in your work or creative projects.
