Today I started my 90-day journey into Artificial Intelligence. No hype, no shortcuts — just learning step by step and sharing what I understand. What I Learned Today I began with Large Language Models (LLMs). Before today, I genuinely thought AI understands language like we do. But the reality is very different. LLMs don’t understand language.They predict the next word. How It Actually Works At its core, an LLM is trained on massive amounts of text data. Given an input like: "AI is changing the..." The model predicts the most probable next word, such as: "world" It does this by learning patterns and probabilities from data — not by understanding meaning. Every sentence generated is just a sequence of these predictions. What Surprised Me Even without true understanding, LLMs can: Write essays Answer questions Generate code This made me realize: Intelligence (in this case) can emerge from simple rules applied at scale. My Takeaway What feels like “thinking” is actually: Pattern recognition Probability Massive training data And somehow, that’s enough to create powerful AI systems. What’s Next? Tomorrow I’ll explore: What tokens are How text gets converted into numbers Day 1 complete. 89 days to go. If you’re also learning AI, let’s connect and grow together.
