AI and LLMs Explained for Beginners: What They Are and How They Actually Work
Artificial intelligence is everywhere: in your phone, your email, your streaming recommendations, and now in chatbots that can write essays and fix code. But if terms like AI, machine learning, and large language models (LLMs) sound confusing, you're not alone. This beginner-friendly guide breaks it all down in plain English. What Is Artificial Intelligence? Artificial intelligence (AI) is the field of computer science focused on building machines that can perform tasks that normally require human intelligence, such as recognizing images, understanding speech, making predictions, or translating languages. Your phone's face unlock and Netflix's suggestions are everyday examples. AI is an umbrella term. Inside it sits machine learning, where computers learn patterns from data instead of following fixed rules.
