Introduction to Large Language Models
Course Description
You've heard about ChatGPT, Gemini, and other AI chatbots. But what's actually happening under the hood? This beginner-friendly course from IBM gives you a clear, non-technical introduction to Large Language Models (LLMs).
You'll learn what LLMs are, how they're built (including the revolutionary transformer architecture), and how they learn to understand and generate human-like text. The course covers the training process (pre-training, fine-tuning, and reinforcement learning from human feedback), the capabilities and limitations of today's models, and practical applications across industries. You'll also explore important topics like hallucinations, bias, and the future of LLMs.
This free, self-paced course takes about 1-2 hours to complete. No technical background or coding is required. It's perfect for business professionals, students, or anyone who wants to understand the technology behind the AI revolution. Upon completion, you'll earn an official IBM Skills Badge.

User Reviews
"I've been using ChatGPT for months but never really understood how it worked. This course explained it perfectly, without any technical jargon I couldn't follow. The section on hallucinations and bias was eye-opening. Now I know why my AI sometimes gives confidently wrong answers. Highly recommended for non-technical people."
"As a product manager, I need to understand AI to make better decisions about our product roadmap. This course gave me the perfect foundation. It's short enough to finish in a lunch break but packed with useful information. The IBM badge is a nice credential for my LinkedIn profile."
"Great overview. I appreciated the historical context—I didn't know that LLMs have been in development for decades. The explanation of the transformer architecture was clear even though I'm not an engineer. My only critique: I wish there was a bit more on how to choose between different LLMs for business use cases. Still, an excellent free course."
