Artificial Intelligence for Beginners: Build a Custom ChatGPT in 3 Steps

Are you excited about using AI in your product but intimidated by all the jargon and complexity? The multitude of random third-party products? Let’s cut through all the fluff: Let me show you how to customize an AI from scratch — and in 3 quick steps.  This course is designed for entrepreneurs, developers, product managers, and curious learners who want to build powerful, custom AI applications—without expensive APIs or third-party subscriptions. You’ll discover the fundamental steps to creating practical, tailored AI solutions using entirely free, open-source tools. And most importantly, we’ll improve your LLM’s capabilities without any training. 

What You’ll Learn

Here’s what we’ll do—fast:

• Pick a real, text-in/text-out problem you care about.
• Define the input, the output, and a quick metric so we can judge quality.
• Try the top model in chat, then the API for repeatable results and cost checks.
• Step down to the cheapest model that still passes your metric.
• Make it reliable with prompt structure and constrained outputs (so it always returns the format your app expects).
• Spin up a small open-source model on free GPUs and wire it up, so you’re not blocked by budget.
